BACKGROUND: Patients with temporomandibular disorders (TMD) mostly suffer from muscle-related pain. Several conservative interventions have been suggested as treatments for TMD in the last years. OBJECTIVE: The aim of this systematic review with meta-analysis was to assess the efficacy of rehabilitative approaches in reducing pain in patients with muscle-related TMD. METHODS: PubMed, Scopus, and Web of Science were systematically searched from inception until April 28th, 2021 to identify randomized controlled trials (RCTs) presenting: patients with painful muscle-related TMD; rehabilitative approaches as interventions; placebo or sham treatment as comparisons; pain intensity, using visual analogue scale as outcome. A meta-analysis was performed to evaluate the overall effect on painful muscle-related TMD patients. PROSPERO registration number of this systematic review is CRD42021251904. RESULTS: Out of 1997 papers suitable for title/abstract screening, 189 articles were assessed for eligibility. Sixteen RCTs were included and most of them (n= 6, 37.5%) investigated the effects of the laser therapy. The meta-analysis revealed that rehabilitative interventions had a significant overall effect size (ES) of 1.44 (p< 0.0001) in decreasing pain in patients with muscle-related disorders. CONCLUSION: Findings of this systematic review with meta-analysis suggested that rehabilitative approaches might be effective in reducing pain in muscle-related TMD patients. However, the low number of RCTs evaluating conservative approaches might impair the synthesis of evidence regarding the different techniques, calling for caution in the interpretation of these results.

Temporomandibular disorders (TMD) are a group of musculoskeletal diseases affecting masticatory muscles and temporomandibular joints (TMJ). In this context, the chronic TMD could be considered as a condition with chronic primary orofacial pain, presenting as myofascial TMD pain or TMJ arthralgia. In this context, myogenous TMD may present overlapping features with other disorders, such as fibromyalgia and primary headaches, characterized by chronic primary pain related to dysfunction of the central nervous system (CNS), probably through the central sensitization. This phenomenon could be defined as an amplified response of the CNS to sensory stimuli and peripheral nociceptive, characterized by hyperexcitability in the dorsal horn neurons in the spinal cord, which ascend through the spinothalamic tract. The main objectives of the management of TMD patients are: decreasing pain, increasing TMJ function, and reducing the reflex masticatory muscle spasm/pain. The first-line treatments are physical therapy, pharmacological drugs, occlusal splints, laser therapy, extracorporeal shockwave therapy, transcutaneous electrical nerve stimulation, and oxygen–ozone therapy. Although all these therapeutic approaches were shown to have a positive impact on the central sensitization of TMD pain, there is still no agreement on this topic in the scientific literature. Thus, in this comprehensive review, we aimed at evaluating the evidence on pain management and rehabilitation for the central sensitization in TMD patients.

Objective To evaluate the best option among orthoses for carpometacarpal (CMC) osteoarthritis (OA) of the thumb, using a network meta-analysis. Data Sources Medline, Embase, Cochrane, and ClinicalTrials.gov registry databases were used. PubMed, Embase, Cochrane Controlled Trials Register, Cochrane, and other databases were used without language restrictions. Study Selection We searched randomized controlled trials (RCTs) on adults with OA of the thumb by studying any orthosis from the beginning to March 10, 2020. Data Extraction Data were extracted and checked for accuracy and completeness by pairs of reviewers. Outcomes were pain and function. Comparative treatment effects were analyzed by random-effects model for direct pairwise comparisons and Bayesian network meta-analyses to integrate direct and indirect evidence. Data Synthesis Eleven RCTs involving 619 patients were included. We evaluated 5 groups, for 4 different orthoses: short thermoplastic CMC splint (rigid CMC) (n=5), long thermoplastic carpometacarpal-metacarpophalangeal splint (rigid CMC-MCP) (n=7), short neoprene CMC splint (soft CMC) (n=1), long neoprene CMC-MCP splint (soft CMC-MCP) (n=5), and one as a control group (n=5). Our results show that all splints were superior to placebo to reduce pain intensity and the top-ranked intervention was the rigid CMC-MCP (surface under the cumulative ranking curve analysis [SUCRA], score: 65.4). In function evaluation, we report a 71.6 SUCRA for rigid CMC. Conclusions Although the current evidence is unclear on the use of the splint in OA of the thumb, it is not known which orthosis is more effective and whether the orthosis is more effective than other interventions. The network meta-analysis shows that a long thermoplastic splint it is the best choice for pain relief and the short thermoplastic CMC splint is the best treatment to increase function. These results may suggest initial treatment with a long rigid orthosis and then a short rigid orthosis.

Padel is a racket sport that has been gaining great popularity and scientific interest in recent years. It could be considered to be a high-intensity intermittent sport with valuable cardiovascular and neuromuscular benefits; however, the risk of injury cannot be neglected. To date, there is still a gap of knowledge in the scientific literature on this emergent sport. Therefore, the present review aims to synthetize the current knowledge on padel game dynamics to better characterize the main risk factors, the injury rate and characteristics, and the most effective rehabilitative treatment strategies. PubMed, Scopus, Cochrane, and PEDro were screened up to January 2022 to identify eligible studies focusing on padel players as participants. Out of 160 records, we included 19 studies, which were focused on match analysis, anthropometric and physical training, the risk of injury, and rehabilitative interventions. The results showed that the high action velocity and the sudden changes in direction during a padel match could represent a risk factor for injuries, especially in untrained players. However, the high heterogeneity of the studies in the literature hinders our ability to draw any strong conclusions, and the results should be carefully considered. Future research should address the lack of knowledge on injury mechanisms and type to implement a tailored rehabilitation program.

To date, the application of oxygen-ozone (O2O3) therapy has significantly increased in the common clinical practice in several pathological conditions. However, beyond the favorable clinical effects, the biochemical effects of O2O3 are still far from being understood. This comprehensive review aimed at investigating the state of the art about the effects of O2O3 therapy on pro-inflammatory cytokines serum levels as a modulator of oxidative stress in patients with musculoskeletal and temporomandibular disorders (TMD). The efficacy of O2O3 therapy could be related to the moderate oxidative stress modulation produced by the interaction of ozone with biological components. More in detail, O2O3 therapy is widely used as an adjuvant therapeutic option in several pathological conditions characterized by chronic inflammatory processes and immune overactivation. In this context, most musculoskeletal and temporomandibular disorders (TMD) share these two pathophysiological processes. Despite the paucity of in vivo studies, this comprehensive review suggests that O2O3 therapy might reduce serum levels of interleukin 6 in patients with TMD, low back pain, knee osteoarthritis and rheumatic diseases with a concrete and measurable interaction with the inflammatory pathway. However, to date, further studies are needed to clarify the effects of this promising therapy on inflammatory mediators and their clinical implications.

Objective To evaluate the influence that COVID-19 lockdown had on the epidemiology of soccer musculoskeletal injuries during 2019/2020 Italian First Football League Serie A in professional football players. Methods In this retrospective study we analyzed records from media-based platform (Trasfermarkt, https://www.transfermarkt.com), describing the epidemiology of muscle injuries before and after the first COVID-19 lockdown phases in Italian professional football players. We also classified the severity of the injury as the number of missing days from participation. Results We assessed a lower prevalence of post-lockdown injuries, albeit showing a similar injury rate at 1000 game-hours (pre-lockdown: 16.9 [13.0-20.7], post-lockdown: 15.5 [9.9-21.1]; RR: 0.92 [0.46-1.8]). All risk ratios for injury rate were not significantly different (p> .05) between pre- and post-lockdown. Conclusions The incidence of muscle injuries has not significantly changed after the first COVID-19 lockdown in Italian professional soccer players. Recognizing injury rates might be crucial for physician to evaluate adequate preventive measures.

The growing number of stroke survivors with residual hand disabilities requires the development of efficient recovery therapy, and robotic rehabilitation can play an important role.The study aims to compare the relative effects of end-effector (EE) and exoskeleton (EXO) hand devices in motor recovery of patients with finger-hand motor impairment stroke.We identified randomized controlled trials (RCTs) through search in database on PubMed, Embase, MEDLINE, Cochrane library until October 2020. We included as outcomes: motricity index (MI), quick version of disabilities of the arm, shoulder, and hand (QuickDASH) questionnaire, and Fugl-Meyer assessment for upper extremity (FMAUE). We performed a systematic review, a meta-analysis, and a surface under the cumulative ranking analysis (SUCRA).We included five RTCs and 149 subjects. MI showed a signifìcant improvement (Despite the limited number of studies included, exoskeleton robotic devices might be a better option than end-effector devices in the treatment of fingers motor impairment in stroke patients. Further studies are still needed to confirm the findings and should focus on a direct comparison of the two devices.

Interleukin (IL)-6 is a soluble factor secreted by T lymphocytes, involved in antibody generation by B lymphocytes. The IL-6 pathway has risen as a pivotal pathway implicated in immune regulation and dysregulation in various rheumatic diseases. Nonetheless, elevated IL-6 levels can also play a role in cancer. Targeting the IL-6 pathway has led to innovative therapeutic approaches for rheumatic diseases and for COVID-19, particularly in the elderly. Indeed, tocilizumab, an agent targeting IL-6, has recently amassed significant attention as a promising univocal agent for different conditions. In this viewpoint, we sought to recall and describe the common pathway among osteoarthritis, rheumatoid arthritis, and cancer, suggesting that anti-IL-6 may be considered a jack-of-all-trades against inflammaging in the elderly.

Purpose To summarize the findings and evaluate the role of vibratory therapy in the rehabilitation of neurological diseases. Methods We systematically research PubMed, Scopus, Embase, Physiotherapy Evidence Database (PEDro), Web of Science, and Cochrane library databases from the inception until November 2020. We included studies that compared whole-body vibration (WBV) or focal muscle vibration (FMV) with placebo, sham, or another form of exercise in neurological disease rehabilitation in children and adults that result in motor impairments and disability. Results We included 16 systematic reviews with good methodological quality evaluated using the Joanna Briggs Institute Umbrella Review Assessment and Review of Information appraisal tool. In stroke patients, WBV appears to play a role in improving gait and balance, while FMV is more effective in reducing spasticity. In multiple sclerosis and cerebral palsy, no evidence suggested that vibration therapy increases some patient outcomes. Conclusion WBV and FMV appear to play a considerable role in reducing spasticity and improving gait, balance, and motor function in stroke patients. By contrast, vibration therapy seems to be unable to reduce spasticity in multiple sclerosis and cerebral palsy. Also, correct use parameters for this therapy could not be defined.IMPLICATIONS FOR REHABILITATIONBased on the growing number of systematic reviews, this umbrella review aimed to summarize the findings and evaluate the role of vibration therapy in the rehabilitation of neurological diseases.Whole-body vibration and focal muscle vibration appear to play a considerable role in reducing spasticity and improving gait, balance, and motor function in patients affected by stroke.Focal muscle vibration appears to be more useful if applied to non-spastic antagonist muscles with reciprocal inhibitory action on spastic muscles in subjects affected by stroke.Vibration therapy seems not to be able to reduce spasticity in multiple sclerosis and cerebral palsy.

Osteoarthritis (OA) is a painful and disabling disease that affects millions of patients. Its etiology is largely unknown, but it is most likely multifactorial. OA pathogenesis involves the catabolism of the cartilage extracellular matrix and is supported by inflammatory and oxidative signaling pathways and marked epigenetic changes. To delay OA progression, a wide range of exercise programs and naturally derived compounds have been suggested. This literature review aims to analyze the main signaling pathways and the evidence about the synergistic effects of these two interventions to counter OA. The converging nutrigenomic and physiogenomic intervention could slow down and reduce the complex pathological features of OA. This review provides a comprehensive picture of a possible signaling approach for targeting OA molecular pathways, initiation, and progression.

Arachnoid cysts (ACs) are congenital intracranial benign cavities originating from the meninges during embryological development. Several studies have shown the existence of a relationship between AC and a higher risk to develop ipsilateral chronic subdural hematoma (CSH) especially in a young population. In the presence of an AC, the practice of sport activities may expose young patients to minor head trauma and to an increased risk of developing CSH. We describe three cases of young soccer players with AC associated with CSH. Then, we performed a literature review of all the reported cases in the literature of patients younger than 18 years with AC-associated CSH related to sport practice. A total of 33 cases, including the three cases reported by us, are analyzed. Soccer is the most represented sport activity in this association (39% of cases). The treatment of choice is surgical in all patients, with burr hole or craniotomy in similar proportions. In one-third of patients, the AC has been fenestrated. Outcome is good in all the reported cases. We reviewed the main pathogenic theories, the main surgical strategies described in literature, as well as recurrence rate of CSH, the association of AC and cranial deformities, and the clinical outcome. AC might be associated with skull deformities, but their real incidence remains unclear. The clinical detection of such anomalies should suggest performing further radiological investigations. If the presence of AC is confirmed, the practice of sport activities should not be avoided, as the real incidence of AC-associated CSH is not clear yet and the reported outcomes in literature are good. Surgical treatment of AC-associated CSH should be hematoma removal through burr hole, reserving AC fenestration only for cases with intracystic bleeding or recurrences. The surgeon should adequately advise and inform the young patients and their families that they could have an increased risk of developing CSH given by the presence of the AC, and that they should be referred to a neurosurgical center if they become symptomatic.

BACKGROUND Hemiplegic shoulder pain (HSP) is a disabling complication affecting stroke survivors. In this context, rehabilitation might play a key role in its clinical management. Recent systematic reviews of the impact of rehabilitative approaches on pain reduction in patients with HSP are lacking. OBJECTIVE This systematic review of randomized controlled trials (RCTs) with meta-analysis aimed to investigate the efficacy of rehabilitative techniques in reducing HSP in stroke survivors. METHODS PubMed, Scopus, and Web of Science were searched from inception to March 8, 2021 to identify RCTs of stroke survivors with HSP undergoing specific rehabilitative techniques combined with conventional therapy to reduce pain intensity. A network meta-analysis and meta-analysis of the Bayesian network of random effects were performed. The risk of bias of studies was assessed with Version 2 of the Cochrane Risk of Bias tool for randomized trials. RESULTS Of 1139 articles identified, 12 were included in the final synthesis. We analyzed data for 723 stroke survivors, reporting a significant overall decrease in pain intensity after a rehabilitative approach by the Bayesian meta-analysis (standardized mean difference 2.78, 95% confidence interval 0.89;-4.59; p = 0.003). We report a significant reduction in HSP with botulinum toxin type A injection (p = 0.001), suprascapular nerve pulsed radiofrequency (p = 0.030), suprascapular nerve block (p = 0.020), and trigger-point dry needling (p = 0.005) as compared with conventional rehabilitation. Concerning the effect size, we identified a Bayesian factor10 of 97.2, with very strong evidence of superiority of rehabilitative techniques. CONCLUSIONS The present systematic review and meta-analysis showed that adding other rehabilitative techniques to conventional rehabilitation was significantly more effective than conventional rehabilitation alone in the complex management of patients affected by HSP.

BACKGROUND: Primary lateral sclerosis (PLS) is an upper motor neurons disease that on rare occasions may determine bradykinesia and motor fatigue. To date, no rehabilitative treatment has been described as useful for these patients. CASE PRESENTATION: A 68-year-old male developed dysarthria, spastic laugh, impairments of handwriting and fine motor, gait and dysphagia disorders for both solids and liquids over the period from 2015 to December 2018, with normal DaT scans and no clinical benefits from therapy with levodopa, pramipexole and baclofen. The patient underwent exercises for gait training and balance control with sensory treadmill and stabilometric platform and kinesiotherapy to improve fine motor skills of both hands and postural changes, five days a week for two weeks. Based on our data, the patient showed an improvement in balance and gait parameters in T2 compared to T1. CONCLUSION: Thanks to the synergistic action of a combined treatment of physical and instrumental therapy, despite the rare pathology and complex disability, the patient had important benefits in terms of performance and independence in daily activity.

Breast cancer (BC) is the most frequent malignant tumor in women in Europe and North America, and the use of aromatase inhibitors (AIs) is recommended in women affected by estrogen receptor-positive BCs. AIs, by inhibiting the enzyme that converts androgens into estrogen, cause a decrement in bone mineral density (BMD), with a consequent increased risk of fragility fractures. This study aimed to evaluate the role of vitamin D3 deficiency in women with breast cancer and its correlation with osteoporosis and BMD modifications. This observational cross-sectional study collected the following data regarding bone health: osteoporosis and osteopenia diagnosis, lumbar spine (LS) and femoral neck bone mineral density (BMD), serum levels of 25-hydroxyvitamin D3 (25(OH)D3), calcium and parathyroid hormone. The study included 54 women with BC, mean age 67.3 ± 8.16 years. Given a significantly low correlation with the LS BMD value (r2 = 0.30, p = 0.025), we assessed the role of vitamin D3 via multiple factor analysis and found that BMD and vitamin D3 contributed to the arrangement of clusters, reported as vectors, providing similar trajectories of influence to the construction of the machine learning model. Thus, in a cohort of women with BC undergoing Ais, we identified a very low prevalence (5.6%) of patients with adequate bone health and a normal vitamin D3 status. According to our cluster model, we may conclude that the assessment and management of bone health and vitamin D3 status are crucial in BC survivors.

Rehabilitation is important for patients with coronavirus disease 2019 (COVID-19) infection. Given the lack of guidelines in English on the rehabilitation of these patients, we conducted a review of the most recent reports. We performed this literature review using the principal research databases and included randomized trials, recommendations, quasi-randomized or prospective controlled clinical trials, reports, guidelines, field updates, and letters to the editor. We identified 107 studies in the database search, among which 85 were excluded after screening the full text or abstract. In total, 22 studies were finally included. The complexity of the clinical setting and the speed of spread of the severe acute respiratory syndrome coronavirus 2, which leads to rapid occupation of beds in the intensive care unit, make it necessary to discharge patients with COVID-19 who have mild symptoms as soon as possible. For these reasons, it is necessary to formulate rehabilitation programs for these patients, to help them restore physical and respiratory function and to reduce anxiety and depression, particularly patients with comorbidities and those who live alone or in rural settings, to restore a good quality of life.

To investigate the effectiveness of commercial exergames treatments on people with Parkinson's disease (PD), a systematic review and network meta-analysis (NMA) of randomised controlled trials (RCT) was performed to evaluate functional locomotion effects in patients with PD.A comprehensive search on PubMed, Embase, Cochrane Controlled Trials Register, the Cochrane, and other databases without language restrictions was conducted. References and reviews were cross-checked for possible studies. RCTs from 2012 were included. Seven studies with 236 participants were included in the NMA that used a random-effect Frequentist model to investigate the standard mean difference of pooled effect sizes change in functional locomotion between baseline and delayed retention tests on six comparisons.The direct comparisons Kinect: Control (These network meta-analytic findings show that Kinect and Wii show immediate positive effects on functional locomotion in people with PD. Compared with Kinect RCTs, Wii may be considered the best therapy for providing functional recovery in PD.Implications for rehabilitationExergames rehabilitation reveals intervention benefits for functional locomotion in people with PD.In patients with cognitive disorders, Wii's platform can be considered a visual reference and a cue to facilitate patients with freezing.Nintendo Wii seems to be a better device for locomotion rehabilitation in people with PD than Xbox Kinect.

Facial nerve paralysis (FNP) has a significant effect on a person’s quality of life. In individuals with FNP undergoing facial rehabilitation, methods to analyze the loss of function are useful in diagnosis, treatment and follow up. To propose a protocol with kinematic analysis coupled with sEMG to evaluate the outcomes of FNP, quantifying the excursion degrees of the facial muscles and symmetry of voluntary movements. 10 patients (Group A) were followed by diagnosis until the end of the rehabilitation program. Kinematic analysis of 20 healthy adults (group B) was performed as a starting point to have a normality range and to test intra-subject and inter- intra rater reliability. An optoelectronic system and sEMG wireless electrodes were used. In Group A, a significant improvement in the movement of frontalis muscle (P = 0.0118) after 4-week treatment from the beginning (T0) 9.8 ± 4.5 mm to the end of rehabilitation (T1) 16.3 ± 5.8 mm and orbicularis oris (P = 0.0143) from T0 14.8 ± 5.5 mm to T1 20.3 ± 3.3 mm and, a reduction of % of maximum voluntary contractions (MVC) at T1 for frontalis and orbicularis compared to T0. This protocol provides meaningful data in a simple, reliable and objective way for the functional assessment of patients with PNF.

Background In the modern era evidence-based medicine, guidelines and recommendations represent a key-point of daily activity. The Spinal Section of the Italian Society of Neurosurgery introduced some recommendations regarding Degenerative Lumbar Spine Stenosis based on those of the Spine Committee of World Federation of Neurosurgical Societies, revising them on the basis of Italian common practice. Methods In June 2019, a Committee of 21 spine surgeons met in Rome to validate the recommendations of the WFNS. Furthermore, they decided to review the ones that did not reach a consensus to create Italian Recommendations on Degenerative Lumbar Spine Stenosis. A literature review of the last ten years was performed and the statements were voted using the Delphi method. Results 41 statements were discussed and 7 statements were voted again to reach a consensus with respect to those of the WFNS. A total of 40 statements reached a consensus, of which 36 reached a positive consensus and 4 a negative consensus, while no consensus was reached in 1 case. Conclusions Conservative multimodal therapy, tailored on the patient, is a reasonable and effective first option choice for the treatment of LSS patients with tolerable moderate symptoms. Surgical treatment is reserved for symptomatic patients non-responding to conservative treatment or with neurological deficits. The best surgical technique to use depends on personal experience; modern MISS techniques are equivalent to open decompressive surgery with some advantages and higher cost-effectiveness. Fusion surgery and mobility preserving surgery only have a marginal role in the treatment of DLSS without instability.

Context: Activation time of the quadriceps is important in determining injury risk in professional soccer players. Objective: To compare the activation time of the quadriceps and hamstrings muscles during a movement that puts stress on anterior cruciate ligament (ACL) to assess the risk of ACL injury. Design: Case series. Setting: University laboratory for movement analysis. Patients or Other Participants: Twenty (10 males and 10 females) professional soccer players. Intervention(s): An inertial sensor and 4 electrodes positioned on the quadriceps and hamstrings muscles were used for the surface electromyography. The athlete resting on 1 leg dropped, from a 32-cm-high platform, on the suspended foot (testing leg), without jumping or lowering his center of gravity and maintaining single-leg landing for 5 seconds. Using a software, it is possible to calculate the activation time of the rectus femoris, vastus medialis (VM), biceps femoris, and semimembranosus muscles before ground contact. Main Outcome Measures: To evaluate the activation times of the rectus femoris, VM, biceps femoris, and semitendinosus muscles before ground contact in comparison with the range of normality calculated by the manufacturer. Results: All male soccer players demonstrated a low risk related to the correct activation of all the examined muscles, while female soccer players demonstrated delayed activation of the VM. Conclusions: Delayed activation of the VM registered in females determines an increase in anterior shear force, which is an important risk factor for incurring an ACL injury. This testing protocol becomes adequate for the screening of high-risk athletes and for targeting interventions to specific imbalances that may increase injury risk.

Background and purpose This study aims to determine the best choice of breathing exercises (BE) for patients with chronic obstructive pulmonary disease (COPD) via a network meta-analysis. Methods We searched randomized controlled trials (RCTs) of adults with COPD investigating any BEs in MEDLINE, Embase, Cochrane Library, and ClinicalTrials.gov databases. The effects of comparative treatment on the St. George Respiratory Questionnaire as the outcome were analysed and ranked according to a surface under the cumulative classification curve (SUCRA) analysis. Results The network meta-analysis included six RCTs involving 280 patients with four intervention groups, comprising control, diaphragmatic breathing training (DBT), yoga, and singing course. Performing SUCRA, we reported that yoga is 75% likely to be the best treatment available as DBT with 66%, instead of 35% for singing and 21% for control. Conclusion DBT and yoga seem to be the best choices for breathing exercises in people with COPD.

Introduction Accurate hemostasis in surgical practice is critical. The need for optimal atraumatic hemostasis has become compelling in neurosurgery. A simple and safe gelified hemostatic matrix is often used. This prospective study evaluates two different hemostatics, FloSeal (Baxter Healthcare, Deerfield, Illinois, United States) and Surgiflo (Ethicon, Somerville, New Jersey, United States), for bleeding control during spine surgery, considering their efficacy, safety, and ease of use. Materials and Methods From January 2012 to December 2013, we recruited 149 patients. Inclusion criteria were age between 25 and 80 years, diagnosis of degenerative or traumatic pathology of the lumbar or thoracolumbar spine, and persistent bleeding not responding to standard hemostatic techniques. All patients underwent laminectomy or laminoarthrectomy, with exposure of the perivertebral venous plexus. Our aim was to stop the bleeding completely in the operative field by application of hemostatic gel. All patients were evaluated during the follow-up period with a clinical and neurologic examination. All patients underwent a computed tomography scan 3 months after the intervention. Results We included 149 patients in our study: 98 men and 51 women. Overall, 92 patients were affected by a degenerative condition and 57 by traumatic pathology. A total of 42 patients had anticoagulant and/or antiaggregant therapy preoperatively. In all cases, massive bleeding originated from the epidural venous plexus. FloSeal was used in 86 cases and Surgiflo in 63. A complete hemostasis was achieved in all patients within 3 minutes, 30 seconds and 7 minutes (FloSeal, 5 minutes, 35 seconds ± 52 seconds; Surgiflo, 5 minutes, 32 seconds ± 54 seconds). Statistical analysis did not show any association between coagulation time and hemostatics, age, sex, and the pathology treated. Previous therapy with antiaggregants and/or anticoagulants determined a slight increase in the time of hemostasis without any statistical differences. The clinical and radiological follow-up showed no evidence of postsurgical hematomas. Conclusions Comparative analysis of the two products did not show any relevant differences in terms of efficacy and ease of use or their effectiveness in bleeding control. Their use was valid even in patients who used antiaggregant/anticoagulant drugs preoperatively. Both FloSeal and Surgiflo can be considered good choices for controlling bleeding in spinal surgery.

Objective To analyze outcomes of patients surgically treated for calcified spinal meningiomas and to determine factors associated with surgical morbidity. Methods Between January 2000 and June 2013, a total of 54 patients underwent surgical resection of a spinal meningioma: 37 of these cases showed various degrees of calcification, confirmed by histopathologic analysis. The clinical evaluation was performed according to the American Spinal Injury Association Impairment Scale. At the last follow-up, neurologic status improved in 19 cases and remained unchanged in 20 cases; just 1 case worsened. According to the American Spinal Injury Association Impairment Scale, neurologic status was classified into 3 levels: poor (A + B), fair (C), and good (D + E). Neurologic status improvement (NSI) during postoperative time (considered as a transition from one lower level to the higher) was analyzed in relationship to the patient's age, length of clinical history, spine level, meningioma's position inside the spinal canal, and its degree of calcification. Results A statistically significant relationship between NSI and the degree of ossification of the meningioma was observed. in particular, a direct relationship with microcalcified meningiomas and an inverse relationship with ossified meningiomas. No relationship was observed between NSI and patient's age, length of clinical history, and the site of the lesion into the vertebral canal. Conclusions The univariate analysis confirms that the degree of calcification affects the outcome, because extensive tumor calcification is associated with an increased surgical morbidity probably.

Purpose The aim of the study is to use an algorithm previously published to decide whether to perform open surgery or percutaneous surgery with short fixation in patients with thoraco-lumbar junction and lumbar spine fractures, and to compare retrospectively surgical and conservative options of treatment. Methods Between 2005 and 2009, two groups of 25 patients were analyzed to compare retrospectively surgical and conservative option of treatment to assess perception of pain and to evaluate quality of life during treatment, to evaluate how quickly patients return to work and to their daily activities, to evaluate patients’ satisfaction. X-ray controls were performed to evaluate the fusion rate at 3 and 6 months and CT scans at 6 months. Results The surgical group had a better functional recovery, a better quality of life and returned to work earlier in comparison to the conservative group. Conclusions We can conclude that the percutaneous procedure seems to give better results in terms of satisfaction and return to normal activities, although both procedures guarantee excellent fusion rates.

BACKGROUND Spontaneous spinal infections (SSIs) represent a rare and serious pathological entity. We tried to study a correlation between type of treatment, timing of treatment and clinical outcome through a multivariate analysis of an observational cohort study with the aim to define what is the optimal clinico-therapeutic management. METHODS We performed a retrospective observational cohort study on all consecutive patients observed in our Institute in a period of 13 years; from 2001 to 2014 we enrolled 50 consecutive patients with symptomatic spontaneous spinal infections (no previous surgery or recent infection in other site), confirmed with diagnostic imaging. The inclusion parameters were: diagnostic imaging, signs and symptoms positive for SSI, no history of recent infection or surgery. Of each parameter analyzed, we calculated mean and standard deviation and when necessary correlation (ρ), covariance (σ) and relation coefficient between type of treatment, timing of treatment and clinical outcome. RESULTS Our results suggest that an increase of one day from the onset of symptoms and the start of therapy leads to an increase in the Oswestry Disability Index Scale both at 6 months than at 1 year, with a statistical relevance, so our experience shows a statistically significant correlation and a positive co-variance between timing and outcome at 6 months and 1 year. CONCLUSIONS SSI are rare, very difficult to diagnose and represent a significant clinical problem. If not properly managed, they may lead to significant impact in the quality of life. The most relevant problem is not the treatment, conservative or surgical, but early diagnosis, so a careful physical, laboratory and imaging examination is fundamental, with an important help provided by isolation of the pathogen and histology. In our experience early diagnosis has a fundamental role. In the light of this, current treatment protocols may require a prompt and multidisciplinary management including infectivologists, neuroradiologists and spine surgeons.

Over the last few years, some hemocomponents have been used advantageously in clinical neurosurgical practice, not systemically via transfusion but topically as a sealant (fibrin glue). This has diverted the attention of many authors to the role of platelets in the healing process. The combination of hyper-concentrated platelets and fibrin glue (fibrinogen, XIII factor, fibronectin) with activated thrombin produces a platelet gel that can be easily applied to "difficult" wounds. This topical use of hemocomponents has gained an important role in regenerative medicine. The authors have considered the possibility of using a preparation with a high autologous platelet concentration applied in addition to autologous bone during vertebral postero-lateral fusion. The aim of the procedure is to induce a higher rate of vertebral fusion. Between November 2007 and November 2008, 14 patients (9 men and 5 women, mean age 58.9) underwent laminectomy, vertebral stabilization and postero-lateral fusion. The number of vertebral levels involved in stabilization was: 1 in 2 patients, 2 in 5 patients, 3 in 5 patients, 4 in 1 patient and 5 in 1 patient. Platelet gel was obtained by taking 16 ml of peripheral venous blood from the patient. For this procedure two patented test tubes were used for each patient, with a capacity of 8 m each. These make up the REGEN-THT(®) (Thrombocyte Harvesting Tube) system that makes it possible to obtain 8 ml of autologous platelet gel in 40-45 min. The addition of Ca gluconate and ethanol at 95% makes it possible to obtain a preparation of plasma rich in platelets and activated thrombin with a platelet concentration five times superior to the haematic one. The platelet gel is combined with fragments of autologous bone and synthetic bone during surgical operation. To allow a comparative assessment of the degree of fusion achieved with and without application of the platelet preparation in each patient, it was arbitrarily decided to use it in only one half of the operative field. All patients underwent serial CT scans 3 and 6 months after surgery as well as plain X-rays to evaluate bone fusion. The reconstructed CT images, especially in sagittal and axial planes, permitted an evaluation of the degree of vertebral fusion and "bone growth". The fusion rate was calculated measuring the increment of bone density on CT images, by means of an evaluation of the ROI (HU) in the newly formed bone, and comparing bone density within the bone callus formed by autologous and synthetic bone alone in the one to which the platelet preparation had been added. A good rate of fusion was observed in all patients. Furthermore, a comparative analysis of ROI at 3 and 6 months after surgery demonstrated a high increase in the fusion rate during the first 3 months after surgery. After 6 months the differences in ROI between the two sides had balanced out. However, at 6-month follow-up examination, bone density in the half of the surgical field in which platelet gel had been added to autologous-heterologous bone was higher in comparison to the contralateral one. Bony neoformation after posterior-lateral arthrodesis is well-evident 3 months after surgery and usually continues gradually for the following 18-24 months. The autologous platelet preparation used seems to accelerate bony deposition and to promote tissue healing, increasing bone density at the level of posterior-lateral arthrodesis. Moreover, this preparation has low production costs and is easy to apply.

OBJECTIVE: This preliminary study considers the feasibility and the results of anterior screw fixation in elderly patients with remote Type II axis fractures. Odontoid fractures are the most common fractures of the cervical spine in people 70 years of age or older. In developing countries, direct anterior fracture fixation is replacing posterior fusion in many cases. Recently, it has been demonstrated that patient age does not influence the outcome in terms of fusion after odontoid screw fixation. There is considerable disagreement about correct treatment in the case of remote fractures. In the literature, there have been no studies considering the feasibility and results of anterior screw fixation in elderly patients with remote Type II axis fractures. METHODS: From 1989 to 2005, we observed 9 patients over the age of 65 years with isolated Type II remote fractures of the dens. All fractures were considered to be inveterate, as the traumatic events had occurred 6 to 12 months earlier. All fractures were treated with anterior infibulation of the dens with single 3.5-mm cannulated screws. RESULTS: A bony fusion was radiologically documented in 7 patients (77%) 4 to 16 months after the intervention. In 1 patient, a fibrous union was observed. The neurological status remained unchanged in all patients, and no patients showed any neurological impairment at the time of follow-up. CONCLUSION: According to our preliminary study, the technique appears to be feasible for remote axis fractures within 12 months of trauma, and it seems to be safe for elderly patients. Further data from additional studies are needed.

The stage of unstable dysfunction, also defined as “active discopathy” by Nguyen in 2015 and configuring the first phase of the degenerative cascade described by Kirkaldy-Willis, has specific pathoanatomical and clinical characteristics (low back pain) in the interested vertebral segment, without the presence of spondylolisthesis in flexion–extension radiography. This clinical condition has been defined as “microinstability” (MI). The term has currently not been recognized by the scientific community and is subject of debate for its diagnostic challenge. MI indicates a clinical condition in which the patient has a degeneration of the lumbar spine, causing low back pain, and radiological examinations do not show a spondylolisthesis. We elaborated a clinical score test based on preoperative radiological examinations (static and dynamic X-Rays, CT and MRI) to detect and assess MI. Then, we enrolled 74 patients, all the levels from L1 to S1 were analysed, for a total amount of 370 retrospectively analysed levels. We excluded patients with degenerative scoliosis, as it is related to an advanced stage of degeneration. The test has been developed with the aim of furnishing quantitative data on the basis of the aforementioned radiological examinations and of elaborating a diagnosis and a treatment for the degenerative pathology in dysfunctional phase, responsible for low back pain. We performed a statistical analysis on the results obtained from the test in terms of significativity and predictive value with a 1-year follow-up, calculating the p value and the χ 2 value. In patients with low back pain and negative dynamic X-Rays, an accurate analysis of the radiological exams (CT, MRI, X-Rays) allows to formulate a diagnosis of suspect MI with a good predictive value. This situation opens many clinical and medicolegal scenarios. The preliminary results seem to validate the test with a good predictive value, especially towards ASD, but they need further studies. On the basis of the results obtained, the test seems to allow a good classification of the dysfunctional phase of the degenerative cascade, identifying and classifying MI as a pathologic entity, defining its pathoanatomical and clinical relevance and elaborating a treatment algorithm.

Background Traditionally, the surgical removal of tuberculum sellae meningioma (TSM) and olfactory groove meningioma (OGM) requires transcranial approaches and microsurgical techniques, but in the last decade endoscopic expanded endonasal approaches have been introduced: transcribriform for OGMs and transtuberculum-transplanum for TSM. A comparative analysis of the literature concerning the two types of surgical treatment of OGMs and TSM is, however, difficult. Methods We conducted a literature search using the PubMed database to compare data for endoscopic and microsurgical techniques in the literature. We also conducted a retrospective analysis of selected cases from our series presenting favorable characteristics for an endoscopic approach, based on the criteria of operability of these lesions as generally accepted in the literature, and we compared the results obtained in these patients with those in the endoscopic literature. Results We believe that making the sample more homogeneous, the difference between microsurgical technique and endoscopic technique is no longer so striking. A greater radical removal rate, a reduced incidence of cerebrospinal fluid fistula and, especially, the possibility of removing lesions of any size are advantages of transcranial surgery; a higher percentage of improvement in visual outcome and a lower risk of a worsening of a pre-existing deficit or onset of a new deficit are advantages of the endoscopic technique. Conclusion At present, the microsurgical technique is still the gold standard for the removal of the anterior cranial fossa meningiomas of all sizes, and the endoscopic technique remains a second option in certain cases.

Background Intramedullary ependymomas represent 40%–60% of spinal cord tumors in adults and can be located along the entire spinal cord. Intradural extramedullary (IDEM) ependymomas are very rare with the exception of tumors located at the filum terminale or conus medullaris, with histologic features of myxopapillary ependymomas (World Health Organization grade I). Case Description We present the case of a 42-year-old woman with an IDEM ependymoma of the craniocervical junction who experienced neck pain for 5 months. Magnetic resonance imaging of the cervical spine and craniocervical junction showed a large IDEM solid-cystic lesion with anterolateral junction spinal cord compression. A preoperative computed tomography scan did not show any calcified lesion, although a partial agenesis of the C1 posterior arch was observed. During surgery, a well-encapsulated IDEM tumor without dural attachment or medullary infiltration was found, and a total en bloc excision was performed. Histologic examination revealed a grade II ependymoma. The patient had an excellent clinical recovery, with no recurrence after 2 years of follow-up. Conclusions To the best of our knowledge, no other cases of craniocervical junction ependymomas with vertebral bone abnormalities are described in the literature. This association supports the hypothesis that these lesions may originate from the extrusion of ependymal cells before neural tube closure. Differential diagnosis should include other extramedullary tumors that are more frequent in this region, such as meningioma, schwannoma, or dermoid tumor.

Object The authors describe a new paracoccygeal approach to the L5–S1 junction for interbody fusion with transsacral instrumentation. The purpose of this technical note is to demonstrate a novel surgical approach, technique, and instrumentation system for the treatment of L5–S1 instability in degenerative disc disease and spondylolisthesis. Methods This technical note highlights the AxiaLif (TranS1) transsacral system as an alternative method to transforaminal lumbar interbody fusion or posterior lumbar interbody fusion. Via a novel presacral approach corridor, a truly percutaneous L5–S1 discectomy, interbody distraction, and fixation are achieved, and retroperitoneal viscera and dorsal neural elements are avoided. Percutaneous pedicle screw fixation is then used to provide additional stabilization at the treated level. Conclusions This novel technique of interbody distraction and fusion via a truly percutaneous approach corridor allows for circumferential treatment of the lower lumbar segments with minimal risk to the anterior organs and dorsal neural elements.

Dynamic X-rays (DXR) are widely recognized as an effective method to detect lumbar instability (LI). They are usually performed with the patient in standing position (SDXR). In our opinion, standing position inhibits micromovements of the lumbar segment interested by the listhesis, thanks to paravertebral muscles antalgic contraction and augmented tone. We aim to demonstrate that DXR in recumbent position (RDXR), reducing the action of paravertebral muscles, can discover hypermovements not evidenced in SDXR.Between January 2011 and January 2013, we studied 200 consecutive patients with lumbar degenerative disease with MRI, SDXR, and RDXR. We aimed to find a correlation between low back or radicular pain and the presence of a spondylolisthesis not showed by the SDXR, but showed by the RDXR.We analysed 200 patients: of the 133 not pathologic in SDXR, 43 patients (32.3 %) showed an hypermovement in RDXR (p = 0.0001) without any significant correlation between hidden listhesis and age, sex, or level involved.The aim of our study is to determine whether in patients with lumbalgy without evidence of listhesis in SDXR, pain can be attributed to a faccettal syndrome or to a spondylolisthesis. Consequence of pain is augmented muscular tone of the paravertebral musculature, particularly in standing position. Augmented muscular tone tries to inhibit the pain generator, attempting to limit the slippage of the involved segment. In patients examined in RDXR, the tone of paravertebral musculature is reduced, showing the hidden spondylolisthesis.

Atlanto Axial Rotatory Dislocations (AARDs) are a heterogeneous group of post-traumatic pathologies typical of the pediatric age, and rare in adults. We describe the case of a 34-year-old woman, developing Atlanto Axial Rotatory Fixation (AARF) after a generalized tonic-clonic epileptic seizure, an extremely rare traumatic cause never described in literature. AARF was detected only 1 month after the accident and nonsurgical treatment was attempted at the beginning. The patient underwent surgery only 2 months after the accident. The best treatment should be conservative reduction within 1 month; when it is not possible, it is advisable to perform surgery as soon as possible. C1–C2 fixation with Harm's technique is the gold standard for fixed luxations. Delay of treatment makes intraoperative reduction more difficult and increase the establishment of the chronic permanent change of neck muscles and ligaments.

Background Intramedullary neuroepithelial cysts are extremely rare and only 15 cases have been reported in the literature. Clinico-radiological features are not indicative of a specific diagnosis; for this reason, diagnosis is based mainly on the histological features. In the literature, total surgical removal is considered the treatment of choice. The risk of recurrence is higher after partial removal and in cases of occlusion of intra-extramedullary shunt. For this reason, a surgical strategy that ensures the shunt patency in case of incomplete removal of the cyst becomes a very safe option for treatment of this pathology. Materials and Methods We report the case of a 51-year-old woman who was found to have a dorsal (D9) intramedullary neuroepithelial cyst. She underwent surgical treatment with partial removal and placement of a Nelaton drainage device (8 French) inside the intra-extramedullary shunt. Results The patient experienced a complete regression of preoperative symptoms and magnetic resonance imaging (MRI) follow-up showed no radiological evidence of recurrence 24 months after surgical treatment. Conclusion Spinal ependymal cysts show a high frequency of recurrence, especially in cases of partial removal of the cyst wall. Unfortunately, the cyst walls are often closely adherent to the spinal cord, making total removal impossible. Intra-extramedullary shunting is a viable option, although there is a high frequency of recurrence in cases of obstruction of the shunt. Placing an 8 Ch Nelaton drain between the dorsal columns is a reliable technique, especially in cases of partial removal. In fact, it allows continuous drainage of cyst fluid and subsequent resolution of symptoms, and it decreases the incidence of recurrences due to obstruction of the shunt.

Spinal synovial cysts are cystic dilatations of the synovial membrane that may arise at all levels of the spine. We describe our experience, paying attention to diagnosis, surgical treatment, and long-term follow-up. Between 1995 and 2007, 18 patients were surgically treated. Of these, three patients were excluded from the study because they presented spinal instability at pre-operative assessment. All patients were evaluated pre-operatively with CT, MRI, and dynamic X-rays, and underwent surgery for removal of the cyst by hemilaminectomy and partial arthrectomy. All patients were evaluated with early MRI and had a minimum 2-year follow-up by dynamic X-rays. None of the patients required instrumented fusion due to the absence of radiological signs of instability on the pre-operative dynamic tests. In all patients, there was an immediate resolution of the symptoms, with evidence of complete removal of the cysts on post-operative MRI. At 2-year follow-up, all patients underwent dynamic X-rays and responded to a questionnaire for evaluation of outcome. None of them showed signs of relapse. The gold standard for treatment is surgery, even though other conservative treatment regimens have been proposed. Correct surgical strategy relies on pre-operative assessment of biomechanical stability for deciding whether patients need instrumented fusion during cyst removal. Patients with no instability signs are suitable for hemilaminectomy with partial arthrectomy, preserving 2/3 of the medial portion of the articular facet, because this represents a valid option of treatment with a low risk of complications and a low rate of relapse.

Atlantoaxial rotatory fixation and atlantoaxial rotatory subluxation are the most frequent manifestations of atlantoaxial rotatory dislocation (AARD) in pediatric population and are often treated conservatively. The objective of this study is to correlate the changes highlighted on MRI T2-weighted and STIR sequences with the duration of conservative treatment.We analyzed nine consecutive patients treated surgically between 1 Jan 2006 and 1 Jan 2010 at the Policlinico Umberto I of Rome. All patients underwent cervical X-ray, computed tomography and magnetic resonance imaging (MRI) (T1 and T2-weighted, STIR, angio MRI). All patients were treated with bed rest, muscle relaxants and cervical collar, and radiological follow-up with MRI and cervical X-ray was performed.According to Fielding's classification, we observed seven patients with a type 1 subluxation and two patients with a type II subluxation. In type 1, STIR and T2 sequences showed a hyperintensity in the alar and capsular ligaments and in the posterior ligamentous system, with integrity of the transverse ligament (LTA). In type 2, the hyperintensity also involved the LTA. During the follow-up, MRI showed a progressive reduction until the disappearance of the hyperintensity described, which was followed by a break with orthotic immobilization.MRI with STIR sequences appears to be useful in addressing the duration of conservative treatment in AARD.

Objectives Several techniques have been proposed for treating cervical spine instability due to rheumatoid arthritis. The aim of this study was to screen the different treatment options used in this pathology to evaluate the best form of treatment when the progression of rheumatoid disease affected the cranio-vertebral junction (CVJ) stability. The most important purpose of this study was to achieve both the efficacy of occipito-cervical fusion (OCF) to stabilize the occipitocervical junction and stop pannus progression. The authors describe their case example and stress, in the light of a literature review, the hypothesis that a stable biomechanical system extended to all the spaces involved, has both direct and indirect effects on RA pannus progression and the condition responsible for its formation, such as inflammation and articular hypermobility. Hence, the aim of this study is to advance this thesis, which may be extended to a wider statistical sample, with the same characteristics. Method A systematic literature research of case report articles, review articles, original articles, and prospective cohort studies, published from 1978 to 2011, was performed using PUBMED to analyze the different surgical strategies of RA involving CVJ and the role of OCF in these conditions. The key words used for the search the were: “inflammatory cervical pannus regression”, “rheumatoid arthritis of the cranio-cervical junction”, “occipito-cervical fusion”, “treatment option in rheumatoid cervical instability”, “altanto-axial dislocation”, “craniovertebral junction” and “surgical technique”. In addition, the authors reported their experience in a patient affected by erosive rheumatoid arthritis (ERA) with an anterior and posterior pannus involving C0-C1-C2. They decided to report this exemplative case to emphasize their own assumptions concerning the association between a posterior bony fusion, the arrest of anterior pannus progression and the improvement of functional outcome, without, however, a direct intervention on the anterior pannus. Result Thirty-seven different studies were identified that reflected search criteria, five of which were literature reviews. The different surgical treatment options in cervical RA disease are described in relation to neurological outcome according to the Ranawat grading system, functional outcome or quality of life according to the Steinbrocker classification, and progression of cervical instability and radiographic index of cranial settling, focusing on the role of OCF.

The objective of this study was to describe step by step our surgical technique of laminotomy and analyze our series with regard to spinal deformities (risk and predisposing factors), postoperative pain and rate of postoperative contusions. Data regarding patients who underwent our technique of laminotomy (N = 40, mean follow-up: 52 ms) (N = 40) between 2002 and 2006 were retrospectively evaluated. The technique used is illustrated in depth. Chronic pain was present in 30% with a mean score of 3/10 cm (Graphic Rating Scale). Postoperative kyphoses occurred in three patients, all below 35 years of age and with laminotomies which involved C2 and/or C7. None of these deformities required further surgical treatment because they were self-limiting or asymptomatic at a mean follow-up of 52 months. Based on the results, our technique proved to be safe and effective in terms of late deformities, blood loss, early and chronic postoperative pain and protection from postoperative accidents over the surgical site.

Background Paragangliomas affecting the filum terminale are extremely rare, benign tumors. The literature yielded thirty-two cases of paraganglioma in this site. Case presentation A 49 year-old-man, whose presenting symptoms were low back pain and left leg weakness, was diagnosed as having a paraganglioma of the filum terminale. The clinical, histological and radiological characteristics of this case, that brings the total number of cases described to 33, are discussed in the light of published data. Conclusions This extremely rare pathology can usually be successfully treated by total surgical resection, which represents the gold standard. In the event of incomplete removal, assiduous long-term follow-up is mandatory.
