Introduction: Bilateral posterior fracture-dislocations of the shoulders occur quite rarely. To the best of our knowledge, this is the first case happening to a young man subjected with bilateral reverse shoulder replacement surgery in a one-step procedure. Case Report: The authors present the case of a Caucasian, 49, alcoholic, male affected by bilateral proximal humeral fracture with posterior dislocation, provoked by an epileptic seizure, and admitted to our hospital. The patient underwent one-step bilateral reverse total shoulder replacement surgery, due the comminution of the fracture and osteopenic pattern. He carried bilateral slings for 1 month after surgery, and after the post-operative radiological evaluation at 1 month, he started with progressive active physiotherapy. Conclusion: Opting for a total replacement instead of osteosynthesis is a valuable option in patients presenting with dislocation-comminuted fractures and alcohol intake induced osteoporosis, even if young.

Amniotic fluid represents a new and promising source of engraftable stem cells. The purpose of this study was to investigate the in vitro effects of platelet-rich plasma (PRP) on amniotic-fluid-derived stem cells (AFSCs) on chondrogenic or osteogenic differentiation potential. Amniotic fluid samples were obtained from women undergoing amniocentesis for prenatal diagnosis at 16–18 weeks of pregnancy. Undifferentiated human AFSCs were cocultured with PRP for 14 days. The study includes two protocols investigating the effects of activated PRP using two different methods: via freeze–thaw cycles and via the addition of calcium gluconate. On the 14th day of culturing, the differentiation potential of the cocultured AFSCs was then compared with undifferentiated AFSCs. Staining with alcian blue solution (ABS) and alizarine red solution (ARS) was performed, and chondrogenic- and osteogenic-associated genes markers were investigated. ABS demonstrated enhanced glycosaminoglycan expression. Cocultured cells expressed chondrocyte-associated genes, determined by real-time polymerase chain reaction (RT-PCR), including type I collagen, type II collagen, COMP, and aggrecan. In regard to the osteogenic markers, osteopontin and bone sialoprotein, there were no changes. In particular, the activation of PRP using the freeze–thaw cycle protocol showed a higher expression of the chondrogenic markers. Our preliminary in vitro results showed that PRP has good potential in the chondrogenic differentiation of AFSCs.

Klippel-Trenaunay syndrome is a rare congenital malformation which may be associated with macrodactyly. The main problem is the need for custom-made shoes. We describe the case of a female newborn affected by Klippel-Trenaunay syndrome, with a larger and longer right foot; the difference increased progressively and, at 5 years of age, the right foot was 50% larger and 38% longer than the left one. Due to the progression of the deformity, reduction surgery was advised to reduce the foot’s width. Resection of the second ray and 2nd cuneiform was performed. The result was excellent and there were no complications during a 10-year follow-up period with a decrease of width and length difference to 10% and 4%, respectively, in comparison to the contralateral foot. There were no gait anomalies. Abnormal foot width and length represented the main problems and guided the surgical strategy. Second ray resection was effective, without complications and with a good long-term functional outcome. Possibility of wearing fashionable conventional shoes without insoles was achieved to the patient’s satisfaction

PURPOSE: Articular fractures of the proximal femur are seldom encountered and there are few studies in literature regarding this topic. To date, only a few large series have adequate follow-up and exhaustive description of treatment and outcome, which, however, often result incomplete and do not allow a comparison. Since there are still uncertainties and debates on which the treatment gold standard should be, the goal of the present study is to carry out a meta-analysis on type I and II Pipkin fracture management to establish the best treatment according to EBM. METHODS: Studies regarding acetabular fractures of the femur head were identified from Google Scholar, Cochrane Library, Medline, ScienceDirect and PubMed; gray studies were searched from the included references’ literature, and using general search engines and Social media; the query to be temporally extended from 1996 to 2020. Only comparative studies were included; we ruled out case-reports, case series, author’s opinion, register databases. RESULTS: Comparing conservative and surgical treatment, we found evidence of a better outcome choosing surgical treatment. We found a significant better outcome with open reduction internal fixation, instead of fragment excision. Comparing failure rate of surgical approaches, we found no statistically significant difference. CONCLUSION: Our study proves that there is evidence in favor of operative treatment rather than conservative in complete or displaced Pipkin fracture Type I + II; open reduction internal fixation should be preferred rather than fragment excision, whenever possible. LEVEL OF EVIDENCE: III. Therapeutic.

Objective: Several symptoms are common to knee osteoarthritis and Baker’s cyst. To what extent each condition contributes to the patient’s discomfort is still a matter of debate. The aim of the present study was twofold: first, to compare the burden of symptoms in patients with isolated knee osteoarthritis and patients with knee osteoarthritis associated with Baker’s cyst; second, to assess the outcomes after conservative treatments. Subject and Methods: Patients suffering from monolateral idiopathic knee osteoarthritis were enrolled. Demographic, anthropometric and clinical data (KOOS scale) were collected. Ultrasound evaluation was performed according to standard protocols. On the basis of the clinical presentation different therapeutic options were used (fluid withdrawal, hyaluronic acid and/or steroids injections). Results: One-hundred and thirty patients were included in the study (97 with isolated knee osteoarthritis, 33 with knee osteoarthritis and Baker’s cyst). In basal conditions, lower scores in KOOS sub-scales were observed in patients with knee osteoarthritis associated with Baker’s cyst and in patients with effusion compared with patients without effusion. At 3 months after therapy significant higher scores were observed in both groups. At 6 months the scores were unchanged in the patients without Baker’s cyst, but worsened in those with Baker’s cyst. Conclusions: The study shows that Baker’s cysts associated with knee osteoarthritis contribute to the burden of symptoms. The conservative treatment of both conditions allows significant improvements, but in the medium term (6 months) the efficacy of the therapy declines in patients with knee osteoarthritis associated with Baker’s cyst.

Objective. The gynecologist often involves the orthopaedic surgeon in the evaluation of pregnant women with previous medical history of pelvic surgery who will give birth. Young women can receive pelvic surgery for proximal femoral fractures, sacro-iliac or pelvic ring fractures, avascular necrosis of the femoral head, hip dysplasia and severe ankylosing spondylitis. The aim of this study is to determine whether such women can accomplish a natural delivery or should have caesarean delivery (C-section). Methods. Pubmed and the Cochrane Database of Reviews were searched for manuscripts including the years 1970 to present. Results. It is important to discriminate between pathological and/or post-surgical conditions affecting the coxo-femoral joint which constitute an absolute contraindication to vaginal delivery from other circumstances that may have a relative contraindication. Orthopaedic relative indications for C-section may include coxo-femoral pathologies where coxo-femoral joint range of motion is limited and women cannot assume a given position that is deemed necessary by the obstetric specialist for natural delivery. Conditions requiring C-section are those producing an insufficient width of the bony birth canal; when the transverse mid-pelvis diameter is

The present study was aimed at identifying a new scaffold/stem cell combination useful to treat large bone defects. Human amniotic fluid stem cells (AFSCs) were expanded in vitro, labeled with a fluorescent cell-permeable dye (PKH26) and transplanted in vivo in a femoral injured rat model. The femoral defect was left untreated (control rats) or filled with hydroxyapatite (HA; natural nanocrystalline carbonated hydroxyapatite-Orthoss®) scaffold alone or loaded with PKH26-labeled AFSCs. All animals were killed 3 weeks after implantation. Both gross anatomy and histological observations revealed a major bone regenerative response in rat specimens treated with HA scaffold, alone or supplemented with AFSCs. Samples injected with HA plus AFSCs displayed the presence of abundant fibrotic tissue, the formation of periosteal woven bone, and an increased presence of blood vessels in the bone marrow, with still fluorescent AFSCs in close proximity. These observations provide evidence that natural HA plus AFSCs represents a promising alternative therapeutic strategy to autologous bone grafting procedures.

Nonsteroidal anti-inflammatory drugs (NSAIDs) remain the most commonly utilised prophylaxis to reduce arthrofibrosis (AF) related to the inflammatory response which leads to a pathological condition called arthrofibrosis. Several NSAIDs have shown to be effective, although postoperative indomethacin has been the historical gold standard. More recently, credit has been given to the use of COX-2 selective inhibitors, due to concerns over gastrointestinal effects, as peptic ulcers, with non-selective COX. However, to date, few studies have compared the therapeutic effects of the two drugs. The aim of this study is to compare the postoperative administration of indomethacin and celecoxib in patients with diagnosis of AF treated with arthroscopic lysis and evaluate joint recovery. In this prospective study, 42 patients were diagnosed with hip, knee and elbow residual AF. The inclusion criteria were age > 18 years and a diagnosis of residual AF, following exposure to a previous traumatic event or surgical treatment; exclusion criteria were patients with 35 or < 18 kg/m2, affected by peripherical neuropathies and presence of heavy functional limitations, active infection, complex regional pain syndrome diagnoses. All patients underwent to arthroscopy, operated by a single surgeon with the same team in the same clinic and postoperatively were randomly divided into two groups, one treated with indomethacin, and the other with celecoxib. Of the patients examined, the following parameter was considered: joint range of motion (ROM) preintervention and post-intervention at 3 months and after 12 months. ROM was analysed with Student t test. The comparison of the ROM between both the 3 months postoperative groups has been shown to be not statistically significant. On the other hand, after 1 year, t-Student test referred to preoperative condition was significantly in favour of the group treated with celecoxib (p = 0.02). Lastly, neither celecoxib nor indomethacin showed any gastrointestinal side effects.

The efficacy of platelet-rich plasma in the treatment for Achilles tendinopathy is debated. Therefore, it is important to know which factors, related to the subjects and/or the disease, are associated with positive or negative outcomes. Aim of this study was to evaluate in a large cohort of patients with Achilles mid-portion tendinopathy which variables were independently associated with a positive outcome after platelet-rich plasma treatment. Eighty-four subjects with Achilles tendinopathy were evaluated by means of VISA-A score and ultrasound and treated with a single platelet-rich plasma injection once a week for 3 weeks. Afterward, a rehabilitation program, based on eccentric training, was implemented. At 3 and 6 months, the relationship between the mean VISA-A score and the following putative predictors was evaluated: sex, age, physical activity, sport, smoking, metabolic risk factors, BMI, symptoms duration, tendon damage, neovessels, adherence to eccentric training. Finally, the percentage of clinically evident positive outcomes (defined as an increase in VISA-A score ≥ 20 points) related to each variable was computed. At final follow-up, using the General Linear Model for Repeated Measures procedure, male sex (0.02), age ≤ 40 (0.05) and adequate eccentric training (0.02) were found to be independently associated with a significant increase in the mean VISA-A score. Moreover, the clinically evident positive outcomes, as previously defined, were significantly associated with male sex (0.01), age ≤ 40 (0.000), BMI ≤ 25 (0.001), symptoms duration ≤ 12 months (0.02) and good adherence to eccentric training (0.004). Younger age, male sex and good adherence to eccentric training can be considered predictors of better results after platelet-rich plasma therapy in Achilles tendinopathy

The aim of this study was to compare the efficacy of a single Bone Marrow Aspirate Concentrate (BMAC) with a cycle of 4 Autologous Conditioned Serum (ACS) injections in the treatment of early-stage knee osteoarthritis (OA). Two groups of 12 patients with degenerative knee OA were treated with a single BMAC injection and with a cycle of 4 ACS injections respectively. Follow-up was set at baseline (t0), one-month (t1) and six-months (t2) evaluating VAS for pain, WOMAC index and range of motion (ROM).We reported a significant improvement in WOMAC after BMAC injection both at t1 (p= 0,001) as well as t2 (p0,001), plus a reduction of VAS values in BMAC group at six months follow-up (p = 0,024). In contrast, no significant differences in ROM between the two groups were observed.Both the approaches are safe and effective in the treatment of knee OA, with a major efficacy of BMAC.

Background: Under conditions of intense exercise, the production of free radicals and cortisol increases, whereas blood levels of testosterone and vitamin D decrease. The aim of the study was to evaluate the behavior of these parameters, ethnic differences, and their relationships with overtraining. Materials and Methods: Fifty professional soccer players were studied. Oxidative stress, testosterone, cortisol, and vitamin D were collected in pre- and mid-competitive season, and their differences in Africans and Caucasians were evaluated. Results: An increase in oxidative stress was observed in mid-season in both groups, but this was more significant in Africans (386 ± 162.6 vs. 277.8 ± 106.9 UCarr, p = 0.005; 2,965.4 ± 815.8 vs. 2,560.6 ± 608.1 BAP, p = 0.035). Levels of testosterone and vitamin D were higher in August compared to February in all participants; in both months, testosterone levels were higher in Africans (11.5 ± 2.4 vs. 9.1 ± 2.6, p = 0.004; 10.3 ± 1.6 vs. 7.7 ± 2.3, p = 0.000), whereas vitamin D levels were higher in Caucasians (39.4 ± 11.1 vs. 33.4 ± 9.7, p = 0.048; 31.8 ± 9.7 vs. 27.4 ± 9.4, in August and February, respectively). Insufficient/deficient levels of vitamin D were more frequently observed in Africans, but the difference was close to significance only in August. Conclusions: Although lower levels of vitamin D and higher levels of cortisol and oxidative stress in mid-season in Africans could have a negative influence on performance, no symptoms of overtraining were observed, probably due to higher levels of testosterone which enable homeostatic balance.

To the Editor: Acute kidney injury (AKI) is a lesser-known complication of hip fracture that may come about owing to decreased kidney perfusion and heightened inflammation from trauma, pain, bleeding, and fasting. Approximately 15%-20% of patients undergoing surgery for a hip fracture develop AKI, with 0.5%-1.8% receiving dialysis. [...]

Background Patients affected by coxarthrosis may be treated surgically with total hip arthroplasty (THA). During the surgical intervention, the hip joint capsule can be completely removed, performing a capsulectomy. Otherwise it's possible to perform a capsulotomy, which allows for capsular conservation. Since there is no scientific evidence demonstrating the superiority of one method over the other, the choice whether to remove or conserve the capsule is at the surgeon's discretion and both procedures are actually accepted. The purpose of our study is to evaluate the differences in functional activities and proprioception in patients who underwent THA and capsulotomy with capsular conservation versus patients who underwent THA with capsulectomy. Methods In order to compare the two surgical techniques of capsulotomy with capsular conservation and capsulectomy, we created a randomized, controlled, double-blind, single-centre, non-pharmacological, interventional, superiority, parallel-group trial. The primary outcome of our study is evaluated using the HOOS scale (Hip disability and Osteoarthritis Outcome Score). Secondary outcomes are: the proprioceptive sensitivity, the postoperative bleeding, the surgical time, the active range of motion, and the ability to walk, sit and stand. The proprioception study is carried out through active and passive repositioning tests. THA is performed through the minimally invasive direct anterior approach. The evaluation tests are carried out in the 15 days preceding the intervention (T0), at 50-day post-operative (T1), and finally at three months after surgery (T2). Discussion Considering that the hip joint capsule is innervated by proprioceptive nerve endings, while the psuedocapsule that replaces the native capsule following a THA with capsulectomy doesn't have any active neurophysiological role, we hypothesize that capsulotomy with capsular conservation at the time of primary THA may lead to better proprioception and therefore better functional recovery.

Stress fractures are common injuries caused by repetitive micro-traumas of the bone. Nowadays, they are widespread amongst the athletes and their treatment is mostly based on the limitation of physical activity, the application of ice, and the administration of analgesics and anti-inflammatory drugs. We present a case of a 26-year-old woman who reported a mono-cortical stress fracture in the anatomical neck portion of the right femur treated with Clody® 200 mg/4 ml. The patient is an amateur runner who complained a progressive pain and functional limitation of the hip joint. No history of recent trauma was present as well as X-rays evidence of fractures. A subsequent magnetic resonance imaging study showed the presence of a mono-cortical stress fracture in the anatomical neck portion of the right femur. The patient was treated with 1 vial of Clody® 200 mg/4 ml a day for 7 days, following 1 vial every 15 days for 2 months without any further therapy as well as physical activity limitation, showing a faster clinical and radiological recovery compared with the most of therapies described in the literature. Concerning our positive experience, the purpose of this study is to give a starting point for further research in order to enlarge the number of studies about that specific approach.

BACKGROUND The testosterone/cortisol ratio has been used in sport physiology to evaluate the balance between anabolism and catabolism; its decrease below 30% has been considered a marker of overtraining. In this framework recent studies in soccer players have investigated the relationships between testosterone, cortisol, vitamin D and reactive oxygen species, but with unconvincing results. The aim of the present study was to evaluate the behavior of such biological parameters and their relationships both in winter (the season of championship) and in summer (off-competition season), characterized by different homeostatic situations. PATIENTS AND METHODS Twenty-seven professional male football players (Second Italian Division), were studied. Blood levels of free testosterone, cortisol, vitamin D and reactive oxygen species were evaluated in August (pre-season training) and in February, in the midseason. A comparison between these two periods was performed and for each of them the relationships between the biological parameters were evaluated. RESULTS Blood levels of testosterone were higher during summer whereas those of cortisol were higher in winter. Vitamin D levels were higher in summer; in this season a positive significant relationship between vitamin D and testosterone was observed (p=0.001), but not in winter (p=0.592). Reactive oxygen species were higher in winter; in this season a significant positive relationship between these substances and cortisol was observed (0.000), but not in summer (p=0.325). CONCLUSIONS In professional soccer players it was found a positive relationship between vitamin D and testosterone in summer and between reactive oxygen species and cortisol in winter. However the question whether such results are genuine cause-effect relationships or mere casual or spurious statistical correlations is still unsolved. As matter of fact, such results could be dependent from other determinants which might drive the aforementioned biological parameters in the same direction. These conclusions must be considered valid only in relation to the experimental conditions (training workload, diet and sun exposure) of the present study.

Background: Open tibial fractures are mostly the result of high-energy traumas and often involve severe injuries with extensive bone and soft tissue loss, damage of muscles and neurovascular structures. Over recent years, the growth of Ortho-Plastic teams, as a well-coordinated bone, joint and soft tissue treatment, contributed to change the approach to these fractures and to achieve higher successful results in lower limb salvage. Unfortunately, many hospitals cannot benefit of a combined team in emergency, and the orthopedic surgeon is forced to manage personally these kinds of traumas. Methods: We retrospectively reviewed all the open tibial fractures treated at our Orthopaedic Department over the last 10 years, in order to assess the treatments performed (one-stage fixation with Intramedullary Nailing or Open Reduction Internal Fixation – ORIF, versus two/multiple-stage fixation with temporary External Fixation followed by nailing or ORIF) and the differences in the outcome between the different methods. Purpose: Based on our experience and review of the literature, the purpose of this paper is to define what cases can be managed by a single-stage orthopaedic approach, and when the orthopaedist should lay down his arms in favor of other specialties.

Dual Mobility (DM) implants provide greater stability especially in Revision Total Hip Arthroplasty (R-THA) when compared to primary THA. Aim: to identify the current evidence regarding outcomes of DM in R-THA when compared to fixed-bearing (FB) implants. Review in accordance with PRISMA guidelines. Structured electronic searches. Primary outcome measure: dislocation rate following R-THA. Secondary outcome measures: implant survival, aseptic loosening, infection rate. Studies' methodology quality assessed using MINORS criteria. All articles published from 2016 to December 2019 included. 1777 R-THAs were reported (49.9% with DM acetabular component, 50.1% with FB component). Sample size: 67-426 patients. Mean age: 57-73. Mean follow-up period: 12-60 months. Significant risk ratio of 1.08 [1.05, 1.12] (95% CI, I2 = 37%, P DM implants are beneficial in R-THA when compared to FB implants. However, one needs to balance the benefits of using DM implant considering the patient’s clinical conditions and the costs involved.

Nowadays venous VTE represents an important perioperative and postoperative complication in patients undergoing elective Major Orthopedic Surgery (MOS). There are significant discrepancies between clinical practice, international recommendations, and published guidelines. Although thromboembolic events may be less common these days than in the past, they can still lead to serious medical complications. Therefore, most patients undergoing MOS procedures are provided with one of the thromboprophylactic treatments. The optimum timing of LMWH administrations remains debated. Customized structured electronic searches in PubMed and Cochrane database. Meta-Analysis, Randomized Controlled Trials, Systematic Reviews on different strategies of the use of LMWH for MOS. Studies on prophylactic regimens showed that subcutaneous LMWH plays a key role in the management of thromboprophylaxis in MOS. However, some controversies still stand. Among those most relevant, it remains unclear whether to start thromboprophylaxis before or after MOS to better balance the risks of clotting and bleeding. With regards to different times of LMWH administration, there is no convincing evidence that starting prophylaxis 12 hours preoperatively is associated with lower risks of VTE compared to prophylaxis started 12 to 24 hours postoperatively. Furthermore, it seems that the most safe and efficient LMWH regimen is the one called “Just-in-time” (LMWH started 6 hours post-op).

Achieving the best possible articular congruity following a tibial plateau (TP) fracture is associated with better long-term functional outcomes; TP has an essential role in the movements of the knee joint and is well established that a not optimal reduction leads to articular instability and early osteoarthritis. In recent times, 3D reconstruction from CT scan has greatly contributed to improve the surgical treatment of these fractures since an accurate preoperative plan gives the possibility to decide the best interventional strategy before the surgical incision. Reduction of the posterior part of tibial plateau is not easily achievable with standard surgical access. Several posterolateral approaches, proposed by authors such as Frosch and Lobenhoffer, have been described over the years; these approaches can be divided into 2 groups: with or without osteotomy of the fibula. Main disadvantages of these techniques are the large skin incision, the difficulty of exposing the lateral face of the tibia, the high frequency of damages of the posterolateral TP corner, and in some cases the necessity of performing fibular head osteotomy . The surgical approach presented in this paper is a simple innovation of the well-known Frosch approach: skin incision is about 12 centimeters in length and runs in a "S" shape with the center positioned over the head of the fibula. It starts 2 centimeters laterally to the tibial crest 6 centimeters below the tibial tuberosity and is directed proximally, curving posteriorly at the level of fibular head and returning straight in the most proximal part; it terminates 4 centimeters posteriorly the lateral femoral condyle. This innovative approach allows the trauma surgeon to achieve an optimal exposure and control of posterior tibial plateau fractures, with the great advantage of being able to treat the lateral tibial plateau with the same surgical incision.

CoViD-19 epidemic started in China in late December 2019, and soon spread, turning into a pandemic. All medical specialties have soon been involved in the management of CoViD-19 patients; the daily Orthopaedic activity has been affected profoundly by this dramatic health emergency. The present paper aims to summarize all the measures and changes that had to be made in order to avoid the healthcare system collapse in the most affected areas, and provides an operative flowchart.

Background and aim of the work: subcutaneous Achilles tendon lesions are common degenerative tendon tears, often related to sport activities, multiple pharmacotherapies and internal medical comorbidities. Neglect an Achilles tendon lesion can affect walk ability, while neglect a bilateral lesion could really lead to a serious limitation of self-sufficiency in daily living. We report a case of chronic bilateral Achilles tendon lesion successful treated with LARS augmentation, along with some clinical considerations concerning the clinical outcome. Methods: we report a case of a chronic bilateral Achilles tendon lesion in an elderly man with multiple comorbidities, successful treated with LARS reconstruction, along with some considerations concerning possible intraoperative issues and the clinical outcome. Results: good functional result was obtained as documented with pre and postoperative American Orthopedic Foot And Ankle Society Scale and the “Foot And Ankle Disability Index”, without complications. Conclusions: a bilateral Achilles tendon rupture is a very disabling pathology, that needs prompt diagnosis and treatment to prevent further complications. LARS reconstruction could be an effective method in selected patients to avoid some intraoperative issues related to patient comorbidities and ability to follow complex postoperative rehabilitation protocols.

Introduction: Running is a very popular modality of physical activity, which may help to lose weight and normalize pathological values of blood parameters in subjects suffering from metabolic disorders. Given that both overuse and metabolic pathologies are responsible for the onset of tendon damage, aim of the present study was to evaluate whether the first group of pathogenetic factors or the latter was more responsible for mid-portion Achilles tendinopathy. Method: Thirty-six and 28 subjects with and without mid-portion Achilles tendinopathy, who were regular runners and started running for metabolic disorders, were enrolled, respectively. Information about body weight and blood parameters at baseline was collected. The characteristics of running practice, dietary habits and anthropometric measures were registered. An ultrasound evaluation of the tendon was performed, and the blood metabolic parameters were evaluated. Results: The amount of running years and mileage was equivalent in both groups. A similar weight loss was observed; the subjects with mid-portion Achilles tendinopathy showed a worse metabolic profile (Hb1aC%, p = 0.008; total cholesterol, p = 0.04; HDL cholesterol, p = 0.003; triglycerides, p = 0.009). Conclusions: These findings suggest that the subjects with less evident positive effects of running on metabolism are more exposed to the onset of mid-portion Achilles tendinopathy.

Introduction Assessing the outcomes of Platelet Rich Plasma (PRP) treatment in Achilles Tendinopathy (AT) may prove difficult due to several methodological reasons. For example, given that the simple mean of VISA-A score is just the result of positive, negative or null values, this may provide incomplete information, and therefore the size of individual changes can remain unknown. On the contrary, calculating the score changes in each subject after treatment would allow a more appropriate evaluation of the clinical results. However, this method has been applied only to few small-scale studies. Therefore we performed a retrospective study aiming to determine: (1) are the percentages of positive outcomes of the present research comparable to those of previous studies performed in different settings? (2) Is there a relationship between the size of increase of the clinical score and the patient satisfaction? Hypotheses The percentages of positive outcomes of the present research are comparable to those of previous studies performed in different settings. Material and methods This is a retrospective observational study. Eighty-four patients submitted to PRP treatment for mid-portion AT were enrolled. Pain and function were evaluated by means of VISA-A scale. Besides the mean, in each subject the pre- and post-treatment difference of VISA-A score was computed and the outcome was defined clinically no detectable, detectable and evident according to the increasing values of the score (0 to 9 points, 10 to 19, and ≥ 20 points change, respectively). The Likert's scale for the patients satisfaction was also used. Results The mean VISA-A increased significantly after treatment (from 50.1 ± 9.1 at baseline to 63.7 ± 13.8 at 3 months (p = 0.00001) and 67.2 ± 14.1 at 6 months (p = 0.00001)). At 3 and 6 months the subjects belonging to the prefixed categories were 15, 45, 24 and 19, 36, 29, respectively. Moreover, large discrepancies were observed between the size of increase of the clinical score and patients satisfaction, mainly for intermediate increases of the score. Discussion The percentages of positive outcomes found in this study are slightly lower than those reported in literature. The different patients expectations about the efficacy of the therapy can explain the discrepancies between the size of increase of the clinical score and the individual satisfaction. In comparison to the simple mean, the individual changes of VISA-A score allow a proper evaluation of the outcomes. The research shows that discrepancies can be present in the percentage of positive clinical outcomes between different studies. The size of increase of the clinical score does not always match patient satisfaction. Level of proof IV retrospective study without control group.

Objective Femoroacetabular impingement (FAI) is a condition that has been increasingly recognized as a source of hip pain and a possible risk factor to early development of hip osteoarthritis (OA). To our knowledge, the use of HA in the treatment of femoroacetabular FAI has been investigated only by two studies, both using a high molecular weight HA. The aim of this study was to evaluate the efficacy of two weekly injections of an hexadecylamide derivative of HA (HYADD4-G, HYMOVIS, Fidia Farmaceutici) in FAI. Methods All patients received two weekly intra-articular injections of Hymovis at baseline and after 7 days. Clinical and functional assessments were performed at baseline and was repeated after 1, 3, 6 and 12 months. Functional measures included visual analogue scale (VAS) for pain, Harris Hip score (HHS), Lequesne Index (LI), Tegner activity level scale (TALS) and monthly consumption of nonsteroidal anti-inflammatory drugs (NSAIDs). Results Twenty-one hips (19 patients, 2 bilateral cases) were treated. The variables VAS, HHS as well as Lequesne improved significantly from T0 to T4 (at 12 months) with the best improvement between T0 and T1. At the same time, a reduction in NSAIDs monthly intake was registered. On the other hand, a significant improvement in Tegner scale was not observed. No adverse events were registered. Conclusion This study states that one cycle of HYADD4-G could be a safe and effective treatment in patients with FAI, showing significative results in term of pain control as well as hip functionality and quality of life up to 1 year.

© 2020 Elsevier Ltd Background: Observational studies have suggested that accelerated surgery is associated with improved outcomes in patients with a hip fracture. The HIP ATTACK trial assessed whether accelerated surgery could reduce mortality and major complications. Methods: HIP ATTACK was an international, randomised, controlled trial done at 69 hospitals in 17 countries. Patients with a hip fracture that required surgery and were aged 45 years or older were eligible. Research personnel randomly assigned patients (1:1) through a central computerised randomisation system using randomly varying block sizes to either accelerated surgery (goal of surgery within 6 h of diagnosis) or standard care. The coprimary outcomes were mortality and a composite of major complications (ie, mortality and non-fatal myocardial infarction, stroke, venous thromboembolism, sepsis, pneumonia, life-threatening bleeding, and major bleeding) at 90 days after randomisation. Patients, health-care providers, and study staff were aware of treatment assignment, but outcome adjudicators were masked to treatment allocation. Patients were analysed according to the intention-to-treat principle. This study is registered at ClinicalTrials.gov (NCT02027896). Findings: Between March 14, 2014, and May 24, 2019, 27 701 patients were screened, of whom 7780 were eligible. 2970 of these were enrolled and randomly assigned to receive accelerated surgery (n=1487) or standard care (n=1483). The median time from hip fracture diagnosis to surgery was 6 h (IQR 4–9) in the accelerated-surgery group and 24 h (10–42) in the standard-care group (p

Objective: The purpose of this study was to investigate the potential ability of autologous conditioned serum (ACS) to decrease pain and improve joint functionality in patients affected by knee osteoarthritis (OA). Methods: Fifteen patients with clinical and radiological signs of OA of the knee were recruited for this study. Each patient received 4 injections of ACS (Orthokine; orthogen, Dusseldorf, Germany) at the site of OA once per week for 4 weeks. Clinical and functional evaluation was performed using the VAS scale for pain, WOMAC scale and KSS functional and clinical scores before the first injection, at one week, at two weeks, at three weeks, at one month and at six months. Statistical analysis was done with the Wilcoxon Signed-Rank Test. Results: Our results show an improvement of all the evaluation scales at 6 months follow-up. Particularly, VAS scales among all patients decreased by 35.8% (p = .00148), KSS functional scores improved by 38.2% (p = .00148), KSS clinical scores improved by 28.9% (p = .00236) and WOMAC scores were reduced by 19.8% (p = .00188). Few adverse effects were observed in our sample. The most common complaint was pain and swelling in the subsequent days after performing the intra-articular injection. Only one patient reported rigidity following the injection of the ACS. Conclusion: Our results, in conjunction with preexisting studies in the medical literature regarding ACS, demonstrate the viability of this therapy for the treatment of knee OA, showing positive influence on pain and joint function without significant adverse effects.

Ankle osteoarthritis (OA) is a painful, disabling condition resulting in dysfunction, impaired mobility, and worsening quality of life; it has a deeply different epidemiology from hip and knee and these may be related to biomechanical aspects. The knowledge of the underlying etiology is fundamental for choosing the best treatment. Primary OA with no history of trauma or general disorder is rare, but the number of such cases has risen in step with the aging of the population. Post-traumatic changes are the main reason of tibiotalar arthritis development (about 65–80%). Among the prevalent subcauses are chronic malalignment, chondral joint damage, chronic instability, and microinstability. Secondary causes of joint degeneration include also dysplasia, inflammatory conditions, infection, hemophilia, and vascular or neurological insults. Many classification systems are based on radiographic evaluation of degenerative changes of the joint. At the present time, there is no definitive consensus about the most valid and reliable scale for assessment of ankle OA.

Introduction Intra-articular (i.a.) hyaluronic acid is an accepted conservative therapy for knee osteoarthritis (OA). This study evaluated the safety and efficacy of a single i.a. injection of an innovative formulation of sodium hyaluronate 2.4% plus sodium chondroitin non-sulphated 1.6% of biotechnological origin (HA-SC) for the treatment of patients with radiographically confirmed symptomatic hip OA and moderate-to-severe pain. Methods In this prospective, multicenter, open-label, pilot study, HA-SC was administered using a standard ultrasound-guided procedure. Adverse events, global/local evaluation of tolerability, and use of rescue analgesics were recorded. Efficacy endpoints included visual analogue scale (VAS) measurement of hip pain, changes in Lequesne’s algofunctional Index, and assessment of global status. Results Treatment was well tolerated; adverse device events of moderate-to-severe intensity, most commonly, injection site pain/localized arthralgia occurred in 20.8% of subjects. Global evaluation of tolerability was rated as excellent or good (75.0%), fair (16.7%), and poor (8.3%) by subjects and 77.1, 14.6, and 8.3%, respectively, by investigators. There was a rapid and significant decrease in hip pain after a single injection; VAS pain score decreased from a mean of 67.5 mm at baseline to 29.3 mm by day 7, with the effects sustained during 6 months of follow-up (P

local glucocorticoids injections are widely administered for the treatment of tendinopathies. positive results have been observed in some tendinopathies but not in others. moreover, worsening of symptoms, and even spontaneous tendon ruptures has been reported. the characteristics of the tendinopathies, the clinical peculiarities of the patient, and the technique used to administer glucocorticoids, can influence the therapeutic response. Areas covered: After reviewing the pertinent literature on the clinical results, basic information, both on the pathogenesis of tendinopathies and the effects of glucocorticoids on tendons, is reported. The pharmacological properties of glucocorticoids are useful to counteract some pathogenetic mechanisms of tendinopathies. However, several experimental studies suggest that the direct action of glucocorticoids on tendons is detrimental. Loss of collagen organization, impaired viability of fibroblasts, depletion of stem cells pool, and reduced mechanical properties have been observed. Expert opinion: Drawbacks of local glucocorticoids injections could be predicted on an individual basis, after a careful appraisal of patient characteristics and concomitant medications, along with the specific stage of tendon disease.

Currently, there is no general consensus about the management of osteoporotic vertebral fractures (OVF). In the past, conservative treatment for at least one month was deemed appropriate for the majority of vertebral fractures. When pain persisted after conservative treatment, it was necessary to consider surgical interventions including: vertebroplasty for vertebral fractures with less than 30% loss of height of the affected vertebral body and kyphoplasty for vertebral fractures with greater than 30% loss of height. Currently, this type of treatment is not feasible. Herein we review the characteristics and methods of operation of three of the most common percutaneous vertebral augmentation systems (PVAS) for the treatment of OVF: Vertebral Body Stenting(®) (VBS), OsseoFix(®) and Spine Jack(®). VBS is a titanium device accompanied by a hydraulic (as opposed to mechanical) working system which allows a partial and not immediate possibility to control the opening of the device. On the other hand, OsseoFix(®) and Spine Jack(®) are accompanied by a mechanical working system which allows a progressive and controlled reduction of the vertebral fracture. Another important aspect to consider is the vertebral body height recovery. OsseoFix(®) has an indirect mechanism of action: the compaction of the trabecular bone causes an increase in the vertebral body height. Unlike the Vertebral Body Stenting(®) and Spine Jack(®), the OsseoFix(®) has no direct lift mechanism. Therefore, for these characteristics and for the force that this device is able to provide. In our opinion, Spine Jack(®) is the only device also suitable for the treatment OVF, traumatic fracture (recent, old or inveterate) and primary or secondary bone tumors.

Rationale: Posterior sternoclavicular joint dislocations (PSCJDs) are particularly rare injuries, accounting for 3% to 5% of sternoclavicular joint dislocations. With very few cases reported in the literature, these injuries are often misdiagnosed and imaging is not always clear, thus making physicians often unaware of them. The present case report aims to investigate a rare case involving a clavicular Salter-Harris II fracture with associated posterior displacement of the diaphysis, a term coined a “pseudodislocation.” Patient concerns: We present a case of a 14-year-old adolescent who sustained a traumatic injury to the shoulder while falling during a soccer match. His main concern was about recovery time and the return to daily life activities. Diagnoses: Multiple imaging studies imaging (X-rays, computed tomography, magnetic resonance imaging) revealed a Salter-Harris II fracture of the right clavicle with posterior displacement of the diaphysis. Interventions: The patient underwent primary surgery to reduce the fracture, using an articular locking compression plate, and secondary surgery to remove the hardware. Outcomes: Following the removal of the hardware at 60 days after the initial surgery and a number of cycles of physiotherapy the patient reported a pain-free range of motion with slight limitation at extremes. Full return to recreational and everyday life activities were achieved at 3 months from the initial surgery. Lessons: The PSCJDs are challenging injuries, as they are surrounded by delicate structures inside the mediastinum. Attention must be taken while diagnosing and treating these injuries as the risk of complications and iatrogenic injuries is high. To the author's knowledge, this case is one of the first of its kind described in the literature where we have a Salter-Harrys type II fracture associated with a posterior pseudodislocation of the lateral clavicle. Given the positive results of the case, we recommend the above-mentioned treatment protocol in PSCJD with associated Salter-Harris II fractures in adolescent patients.

Objectives: The efficacy of platelet rich plasma in the treatment of Achilles tendinopathy is controversial. Despite positive results observed in open studies, randomized controlled trials failed to show difference against saline or rehabilitation. Aims of this retrospective observational study were to compare the efficacy of platelet-rich plasma and dry needling and to assess possible differences age and sex-related. Methods: Groups of 46 and 38 patients with non-insertional Achilles tendinopathy were treated with platelet-rich plasma and dry needling (once a week for 3weeks), respectively. At baseline, 3 and 6months, pain and function scores and the percentage of satisfactory outcomes were evaluated. Sub-group analyses were performed according to age and sex. Results: At 3 and 6months no differences in terms of pain and function between groups were observed, but the percentage of subjects reporting satisfactory results, at 6months, was higher in platelet rich plasma group. Better results were observed in younger subjects, with a greater reduction of pain, improvement of function, and accordingly of the percentage of positive outcomes. A trend toward better results was also observed in males. Conclusion: Beneficial effects of platelet rich plasma and dry needling in non-insertional Achilles tendinopathy have been observed only in some subjects, but not in others; platelet rich plasma shows a slight superiority against dry needling, mainly in younger persons; finally, a gender difference in the therapeutic response can be hypothesized.

Background The aim of this retrospective study was to evaluate the outcome of patients with intra-articular calcaneal fractures treated using a minimally invasive locking nail (Calcanail®). Methods Between January 2016 and April 2017, 15 patients (9 men and 6 women) with a calcaneal fracture were consecutively treated with Calcanail®. The Bohler angle was recorded on standard X-rays pre- and post-operatively. The articular reduction of the posterior facet was evaluated with the Goldzak index in a CT scan 3 months post-operatively. The mean age of the patients was 53 years (range, 24–78). Mean final follow-up was 18 months (range, 12–24). Results Six fractures were classified as Sanders II, 7 as Sanders III and 2 as Sanders IV. In 13 out of the 15 patients treated, the post-operative Bohler angle was of more than 20°. Goldzak index was deemed as excellent in 73.5% of the cases (11 patients), good in 20% of cases (3 patients), and poor in 6.5% (1 patient). Post-operative mean AOFAS score was 85 (range, 60–96). Conclusions The Calcanail® provides good restoration of the subtalar joint and the calcaneal angles with the advantages of a minimally invasive approach. It was effectively used in Sanders types II and III, even in the presence of poor cutaneous conditions.

The combined use of hyaluronic acid and platelet-rich plasma has never been reported in the treatment for osteoarthritis. Aim of this paper was to evaluate the efficacy of this association and to compare retrospectively these results with those of a cohort of patients treated with platelet-rich plasma only. Subjects with mild-to-moderate knee osteoarthritis were enrolled. After clinical and ultrasound evaluation, patients received a weekly intra-articular injection of 2 ml of hyaluronic acid added with 2 ml of platelet-rich plasma for 3 weeks. Follow-up was performed at 1, 3, and 6 months. The same clinical parameters were retrospectively collected from a cohort of patients treated with 4–5 ml of platelet-rich plasma only. Forty knees were treated in both groups. The intra-group comparison showed a significant improvement in clinical and functional outcomes at 1, 3, and 6 months, while the infra-group comparison did not show any significant difference. The association of platelet-rich plasma + hyaluronic acid has the same efficacy of platelet-rich plasma only, administered in higher volume. We may infer that hyaluronic acid works synergically and improves the activity of several molecules contained in platelet-rich plasma.

Background Chronic ankle instability is defined by an instability lasting more than 6 months, in those cases where a comprehensive conservative treatment fails a surgical stabilization is required. Several surgical techniques have been proposed for the management of the chronic lateral instability of the ankle and even after 50 years, the Brostrom–Gould technique is still considered the gold standard for the treatment of this pathology. Recently, many authors have developed completely arthroscopic lateral ligament repair and the use of these procedures is rapidly increasing. The aim of this review is to provide an updated overview of open and new arthroscopic lateral ligament repair techniques in order to summarize and compare the effectiveness of these strategies. Methods A systematic literature review using PubMed/Medline databases was performed (July 1972–July 2015). Clinical results, satisfaction rate and complications of both patient populations were recorded and statistically analyzed. Results The total ankles treated with an open Brostrom ATFL repair in the 13 studies was 505 with a mean follow up of 73.4 months (range 9 months–27.9 years). Postoperative AOFAS score was reported in 11 studies, with a mean value of 90.1 (range, 60–100), patient's satisfaction rate was 91.7%. Surgery-related complications occurred in 40 (7.92%) out of 505 treated ankles. The total number of ankles treated within the 6 arthroscopic studies was 216 with a mean follow up of 37.2 months (range 6 months–14 years). Five studies reported a mean postoperative AOFAS score of 92.48 (range, 44–100) with a patient's satisfaction rate of 96.4%. Surgery-related complications were observed in 33 (15.27%) cases. Conclusions The results of this review show the excellent efficacy of open and arthroscopic surgical procedures in the treatment of the chronic ankle instability. The higher complication rate of arthroscopic procedures respect to the open ones represents the major issue: however, this does not seem to affect the patient's satisfaction. Because of statistical heterogeneity observed no definitive conclusions can be statistically drawn. Finally, to definitively validate the effectiveness of arthroscopic procedures prospective and comparative studies are needed.

PURPOSE:Platelet rich plasma and high volume image guided injections of saline have been used in the treatment of patellar tendinopathy with positive results. As the different mechanisms of action do not interfere each other, it can be hypothesized that they can be used in combination. Aim of this study was twofold: first, to evaluate the efficacy of these two treatments in the management of patellar tendinopathy; second, to verify whether the combination of these therapies could provide further advantages.METHODS:Fifty-four patients suffering from patellar tendinopathy were enrolled. After clinical (VAS and VISA-P) and sonographic evaluation, two ultrasound guided injections (2 weeks apart) of platelet rich plasma, high-volume image-guided injections of saline, or both in association were performed. The VAS and VISA-P scores obtained from the three treatments groups (18 patients in each group) were compared across the different follow-up times (3 and 6 months).RESULTS:In the short term both treatments showed comparable efficacy, whereas in the medium term the positive effects of high-volume image-guided injections gradually diminished and platelet rich plasma showed greater efficacy. Better results (reduced pain, improved function and increased number of subjects who exhibited optimal recovery [> 20 points in VISA-P score]) were observed when both procedures were associated.CONCLUSIONS:The contemporaneous administration of platelet rich plasma and high volume image guided injections of saline treatments, which influence tendon repair by means of different mechanisms, grants a greater improvement for patellar tendinopathy. This finding has clinical relevance, given that this condition has a substantial impact on sports and work performance.LEVEL OF EVIDENCE: III.

A fit 26 year-old-man presented to our Department with an open fracture of the left tibial shaft (AO 42-C3). The fracture was initially treated with an External Fixator, which was replaced by an intramedullary Grosse Kempf nail after 4 months. In the following year he developed an atrophic non-union and we witnessed the increasing bone resorption at the fracture site which led to the nail breakage. An accurate CT pre-operative planning was made and a revision surgery was successfully performed: the broken nail was removed and intercalary allograft reconstruction was made, using a compressible intramedullary nail. Whereas in literature it is well described how intercalary allografts can be used to fill the massive diaphyseal defects after tumor resections, we assumed it could also be an adequate technique to treat a large bone defect at a non-union site.
