Background: Frailty associated with aging increases the risk of falls, disability, and death. The aim of this study is to explore gender-related disparities in the survival outcomes of pathological femoral fractures in older frail patients, while analyzing potential specific prognostic factors. Methods: This study is a retrospective observational analysis conducted at a single medical center. It enrolled all patients aged 65 and above who were admitted to our emergency department between 2016 and 2020 with a diagnosis of pathological femur fracture requiring surgical intervention. The primary study endpoint was evaluating gender-related differences in survival outcomes. The secondary endpoint involves investigating gender-specific prognostic factors through the analysis of clinical and laboratory parameters. Results: The average Charlson Comorbidity Index (CCI) was slightly lower in men, but the difference was not statistically significant (p = 0.53). The Clinical Frailty Scale (CFS) showed similar results, with men and women 5.23 (SD 1.46), also not significant (p = 0.83). An evaluation comparing patients aged 75 years or younger to those older than 75 years found significant differences in health metrics. The average CCI was higher in the over 75 group compared to the under 75 group, with a p-value of 0.001. Similarly, the CFS average was also greater in the over 75 group than in the under 75 group, with a p-value of 0.0001. Complications were more frequent in patients over 75 and those with lower educational qualifications. The evaluation analyzed cardiac patients compared to a control group, revealing that the average age of cardiac patients was 75.22 years, while the control group was younger at 73.98 years (p = 0.5119). The CCI for cardiac patients averaged 6.53, significantly higher than 4.43 for non-cardiac patients (p = 0.0003). Conclusion: Frailty assessment is therefore essential in patients with pathological fracture of the proximal femur and is an important predictor of both gender differences and hospital complications. Enhancing gender analysis in this field is crucial to gather more robust evidence and deeper comprehension of potential sex- and gender-based disparities. [ABSTRACT FROM AUTHOR]

Objectives There is still controversy over the choice of treatment for end‐stage spinal metastases. With the continuous development of microwave technology in spinal tumors, related studies have reported that microwave combined with techniques such as pedicle screw fixation and percutaneous vertebroplasty can achieve the purpose of tumor ablation, relieving spinal cord compression, enhancing spinal stability, effectively relieving pain, and reducing recurrence rates. This study aimed to analyze the effectiveness of microwave ablation combined with decompression and pedicle screw fixation in the palliative management of spinal metastases with pathological fractures. Methods This retrospective study enrolled 82 patients with spinal metastases and pathological fractures treated between January 2016 and July 2020, with 44 patients undergoing pedicle screw fixation along with laminectomy (fixation group) and the remaining 38 receiving microwave ablation in addition to the treatment provided to group fixation (MWA group). Before surgery, all patients underwent pain assessment using the visual analogue scale (VAS) and evaluation of spinal cord injury using the Frankel classification. After surgery, the patients' prognoses were assessed using the Tomita score, modified Tokuhashi score system, and progression‐free survival. Additionally, we compared operative time and blood loss between the two groups. Survival analysis utilized the Kaplan–Meier method with a log‐rank test for group comparisons. Paired t‐tests and the Mann–Whitney U test were applied to metric and non‐normally distributed data, respectively. Neurological function improvement across groups was evaluated using the χ2 test. Results All patients were followed up for a median duration of 18 and 20 months in the fixation and MWA groups, respectively, with follow‐up periods ranging from 6 to 36 months. Statistically significant reductions in postoperative VAS scores were observed in all patients compared with their preoperative scores. The MWA group exhibited reduced blood loss (t = 2.74, p = 0.01), lower VAS scores at the 1‐ and 3‐month follow‐ups (t = 2.34, P = 0.02; t = 2.83, p = 0.006), and longer progression‐free survival than the fixation group (p = 0.03). Although the operation times in the MWA group were longer than those in the fixation group, this difference was not statistically significant (t = 6.06, p = 0.12). No statistically significant differences were found regarding improvements in spinal cord function between the two groups (p = 0.77). Conclusion Compared with decompression and pedicle screw fixation for treating spinal metastases with pathological fractures, microwave ablation combined with decompression and pedicle screw fixation showed better outcomes in terms of pain control, longer progression‐free survival, and lower blood loss without increasing operative time, which has favorable implications for clinical practice.

Background/Objectives: Pycnodysostosis is a rare genetic disorder causing skeletal dysplasia. It is determined by a gene mutation leading to cathepsin K deficiency and predisposes a patient to osteosclerosis, resulting in increased bone fragility. The altered bone quality typical of this disease is responsible for an increased risk of fractures. The purpose of our study was to evaluate the orthopedic manifestations and potential pitfalls in the surgical treatments of pathological fractures in a series of patients treated in our institution who were affected by pycnodysostosis. Methods: We retrospectively evaluated clinical and radiographic characteristics of five patients with pycnodysostosis treated for pathological fractures at our hospital in the past 5 years. Results: Two male and three female patients were included in this study. Four patients had a family history of pycnodysostosis. All the patients were of short stature, but only two underwent growth hormone treatment. All the patients experienced fractures, mostly in their lower limbs and occurring as a result of low-energy trauma. Most of the patients experienced either consolidation delay or nonunion. Conclusions: The orthopedic management of fractures in patients with pycnodysostosis poses an ongoing challenge for orthopedic surgeons. The fact that the bone is simultaneously sclerotic and brittle makes any orthopedic surgical treatment challenging and at a high risk of nonunion in any case. [ABSTRACT FROM AUTHOR]

Introduction: brown tumors result from changes in bone metabolism due to primary, secondary, or tertiary hyperparathyroidism. Their significance lies in the increased risk of pathological fractures, pain, disability, and functional limitation they can cause. Case reports and discussion: this case series report presents 3 patients with secondary hyperparathyroidism due to chronic kidney disease (CKD) who had not been diagnosed or treated and had sustained pathological fractures. These cases were presented at a referral hospital in southwestern Colombia. The clinical, radiological, and surgical characteristics are described. Additionally, a critical literature review is conducted on secondary CKD-related hyperparathyroidism to emphasize the importance of diagnostic suspicion, as nearly 1 in 3 patients with advanced-stage CKD will develop secondary hyperparathyroidism, leading to a high risk of pathological fractures associated with significant morbidity.

Multiple myeloma is the most common primary malignant disease of the spine, which can lead to pathological fractures with consecutive instability and immobilizing pain, due to osseous destruction of individual vertebral bodies. The different surgical care is challenging, although good stabilization should be achieved if possible. The resulting blocking of micro-movements leads to pain minimization. However, this is a symptomatic therapy and does not address the primary disease. In the following, we report on successful transoral balloon kyphoplasty for the treatment of myeloma-related osteolysis with a pathological fracture of vertebral body C2, which led to a significant clinical improvement.

Aims: The modern prevalence of primary tumours causing metastatic bone disease is ill-defined in the oncological literature. Therefore, the purpose of this study is to identify the prevalence of primary tumours in the setting of metastatic bone disease, as well as reported rates of pathological fracture, postoperative complications, 90-day mortality, and 360-day mortality for each primary tumour subtype. Methods: The Premier Healthcare Database was queried to identify all patients who were diagnosed with metastatic bone disease from January 2015 to December 2020. The prevalence of all primary tumour subtypes was tabulated. Rates of long bone pathological fracture, 90-day mortality, and 360-day mortality following surgical treatment of pathological fracture were assessed for each primary tumour subtype. Patient characteristics and postoperative outcomes were analyzed based upon whether patients had impending fractures treated prophylactically versus treated completed fractures. Results: In total, 407,893 unique patients with metastatic bone disease were identified. Of the 14 primary tumours assessed, metastatic bone disease most frequently originated from lung (24.8%), prostatic (19.4%), breast (19.3%), gastrointestinal (9.4%), and urological (6.5%) malignancies. The top five malignant tumours resulting in long bone pathological fracture were renal (5.8%), myeloma (3.4%), female reproductive (3.2%), lung (2.8%), and breast (2.7%). Following treatment of pathological fractures of long bones, 90-day mortality rates were greatest for lung (12.1%), central nervous system (10.5%), lymphoma (10.4%), gastrointestinal (10.1%), and non-renal urinary (10.0%) malignancies. Finally, our study demonstrates improved 90-day and 360-day survival in patients treated for impending pathological fracture compared to completed fracture, as well as significantly lower rates of deep vein thrombosis, pulmonary embolism, urinary tract infection, and blood transfusion. Conclusion: This study defines the contemporary characteristics of primary malignancies resulting in metastatic bone disease. These data should be considered by surgeons when prognosticating patient outcomes during treatment of their metastatic bone disease. Cite this article: Bone Jt Open 2023;4(6):424–431.

As managing pathological fractures of the extremities can be difficult, the present study aimed to present a treatment algorithm for lower extremity bone malignancies. A total of 38 patients with impending and pathological fractures were treated at the Department of Orthopedic Surgery in Kindai University Hospital. Age, sex, fracture site, type of primary malignancy, number of metastases, pre-fracture Eastern Cooperative Oncology Group performance status (ECOG-PS) score, adjuvant therapy, treatment modality, operative time, blood loss, postoperative complications, Musculoskeletal Tumor Society (MSTS) score, outcomes, follow-up period and the MSTS scores and ECOG-PS were compared in cases of primary malignant tumors and those cases of metastatic malignant tumors were retrospectively surveyed. Post-treatment MSTS scores in cases of impending and pathological fractures were compared between intramedullary nail fixation and non-intramedullary nail fixation procedures. Disease sites included the sub-trochanteric femur in 10 patients, trochanteric femur in 8, femoral diaphysis in 7, femoral neck in 5, bilateral trochanteric femur in 3, proximal tibia in 3 and distal femur in 2 patients. A total of 10 patients had metastases between 3-20 sites. The median pre-fracture ECOG-PS score was 1. Adjuvant radiotherapy was administered to 5, chemotherapy to 8 and radiotherapy with chemotherapy to 10 patients. Surgical procedures included intramedullary nails in 18 patients, tumor arthroplasty in 4, plate fixation in 3, artificial head replacement in three, compression hip screw (CHS) in 3, conservative treatment in 2, bilateral intramedullary nail fixation in 2 and artificial bone stem with combined intramedullary nail and plate fixation, right-sided artificial head replacement and left-sided CHS in 1 patient each. The MSTS score was 19.9±8.95 for intramedullary nail fixation and 24.3±7.45 for other procedures, with a negative association between the MSTS score and pre-fracture ECOG-PS. The median follow-up period was 8 months. The outcomes were as follows: Alive with disease, 23 patients; continued disease-free, 1 patient; and dead due to disease, 14 patients. The 1-year postoperative overall survival rate was 60.5%. Moreover, the group with metastatic malignant tumors, which had significantly worse ECOG-PS, had significantly lower MSTS scores than the group with primary malignant tumors. The authors' treatment algorithm for malignant bone tumors of the lower extremity was shown to be useful. [ABSTRACT FROM AUTHOR]

Objective: To assess inter- and intra-observer reliability of Mirels scoring for the determination of pathological fracture risk in metastatic bone lesions of 30 patients among six different levels of experienced orthopedic surgeons who were trained in the same university clinic. Material and Methods: Thirty patients were randomly selected from oncology unit consultations. Six observers were selected in accordance to their orthopedic experience. Mirels parameters except pain were evaluated by observers on two different times without the observers being aware of each other. Results: The Fleiss’ Kappa values were detected as κ=0.21, p<0.0001, and κ=0.15, p<0.0001 by inter-observers at the first and second observational points, respectively. The Kappa values were in perfect (κ=0.95), fair (κ=0.27) and fair (κ=0.10) agreements for the region, size and type of the metastatic involvement by inter-observers at the first observational point. The same parameters had similiar scores as κ=0.83, κ=0.13 and κ=0.28 for region, size and type for the second observation. Fair (κ=0.333), moderate (κ=0.413), fair (κ=0.225), slight (κ=0.035), fair (κ=0.369) and poor (κ=0.030) evidence of agreements were detected in the comparison of the first and second observations for total scores in seniority order. Conclusions: Kappa analysis showed perfect agreement for region, but slight to fair for size and type. There was a significant difference in overall scores across experience levels for the most and least experienced observers. A new rating system with revised parameters may be required to predict impending fractures. [ABSTRACT FROM AUTHOR]

Exogenous steroids are a staple of modern medicine, with utility in a variety of direct and supplemental treatment modalities. However, all pharmaceuticals are undoubtedly coupled with unique side effect profiles, and steroids are no exception. In the case presented, the assessment and management of a 36-year-old male who inappropriately self-administered high-dose steroids for prolonged periods of time is reviewed. In doing so, attention is drawn to both the impact of glucocorticoid-induced osteoporosis and the greater risk of online availability of these powerful medications., (© 2024 The Authors.

Hereditary Sensory and Autonomic Neuropathy (HSAN) Type II is an autosomal recessive genetic disease which presents predominantly with sensory neuropathy and neuropathic ulcers. HSAN Type II is a rare disease, and in the few cases that have been reported, the focus has been on identifying genetic markers of the disease. Orthopaedic conditions may be a major presentation of the disease, and the prevention of superficial trauma and foot care is the only definitive management. [ABSTRACT FROM AUTHOR]

A high prevalence of proximal femoral metastases persists in patients with cancer, particularly regarding lower extremity fractures. This study offers a detailed analysis of clinical characteristics of patients undergoing surgical treatment for pathological or impending fractures, enhancing treatment strategies for metastatic malignancies. A total of thirty patients who underwent treatment of impending and pathological fractures at Kindai University Hospital (Osakasayama, Japan) were included. The retrospective study comprised parameters including age, sex, fracture site, type of primary malignancy, number of metastases, pre-fracture Eastern Cooperative Oncology Group performance status (ECOG-PS) score, adjuvant therapy, treatment modality, operative time, blood loss, postoperative complications, Musculoskeletal Tumor Society (MSTS) score, outcome and follow-up period. Post-treatment MSTS scores were compared in cases of impending and pathological fractures, and between intramedullary nailing and other surgical procedures. In addition, one-year postoperative survival rates were calculated. Furthermore, operative time, blood loss and survival rates were compared between impending and pathological fractures. The participants' median age was 70.5 years, with disease sites primarily in the subtrochanteric femur, trochanteric femur, femoral diaphysis, femoral neck and other locations. Pathologies included multiple myeloma and unknown primary, lung, breast, kidney, liver, gastric, esophageal and uterine cancers. The median ECOG-PS score pre-fracture was 2. Treatment approaches involved radiotherapy, chemotherapy and a combination of both. Surgical interventions included intramedullary nailing (16 cases), endoprosthesis (1 case), bipolar head replacement (3 cases) and compression hip screw (3 cases), among others. A negative correlation (R=-0.63) existed between MSTS and pre-fracture ECOG-PS scores. The operative time was significantly shorter in impending than in pathological fractures, with impending fractures showing significantly lower blood loss. The treatment algorithm for malignant bone tumors of the lower extremity provided in the present study was efficient, potentially optimizing treatment strategies for such cases, and contributing to improved patient care and outcomes in oncology and orthopedic surgery.

Secondary nutritional hyperparathyroidism (NSH) is a metabolic disease characterized by the symptoms such as lameness, constipation, lordosis, and pathological fractures resulting from Ca and P imbalance. A five months old captive-bred two lion cubs were presented with pain in the whole body, reluctance to move, and growth retardation with no history of trauma. Radiographs revealed generalized osteopenia, multiple fractures of all limbs, and lordosis of the caudal vertebrae. Some of these fractures were nonunion. Based on radiographic findings and a history of an exclusive chicken liver diet and goat milk since weaning (after 1 month age), a diagnosis of nutritional secondary hyperparathyroidism was made. The diet was changed to a portion of commercial kitten food, vitamin D supplements, goat milk. Operative interventions were performed to repair the fractured bones and for those which were not suitable for operation, bandage was applied. Cubs were given cage rest for 8 weeks. At the end of these processes, patients were discharged walkable.

Proximal femur simple bone cysts (SBCs) are rare in children, but with a risk of pathological fractures and the associated poor outcomes. This study aimed to evaluate the functional and radiographic outcomes of children with proximal femur SBCs. 38 children with proximal femur SBCs treated surgically at our department, West China hospital, were enrolled in the study. Patients were divided into two groups according to whether pathological fractures presented before treatment. The non-fracture group received treatment of open curettage, cavity electrocauterization, bone grafting, and fixation (proximal femoral plate, intramedullary nail or Kirschner wire). The pathological fracture group received the same procedures of curettage, electrocauterization, grafting, and fixation. Autogenous iliac bone grafting was done in all cases, and the artificial bone was used as a supplementary based on the size of the cavity. Postoperatively, all patients underwent hip spica or similar orthosis immobilization for six weeks and received the same rehabilitation program after the removal of hip spica. Patients were evaluated by two independent observers, including the functional results based on the Ratliff's criteria, avascular necrosis, healing rate based on the Neer scoring system, coxa vara, and premature physeal arrest. We described the good outcome in Ratliff's criteria as "Satisfactory results", and fair and poor outcomes as "Unsatisfactory results." Grade 1 and grade 2 Neer results were termed as failures in treatment, and grades 3 and 4 were considered successes and healing. 38 patients with 38 hips (18 on the left side and 20 on the right side) were evaluated, including 9 females and 29 males, with a mean age of 9.0±2.6 years old (range, 5 to 14 years). There was no significant difference between these two groups in the baseline data of gender, age, side, grafting, staging, and fixation methods. The rate of unsatisfactory functional results in the pathological fractures group was 56.3% (9/16), significantly higher than that in patients without fracture (22.7%, 5/22. p= 0.047). There was also a significant difference in avascular necrosis of the femoral head between the pathological fractures group (7/16) and the group without fracture (2/22, p=0.021). Thirty cases presented with healing, including 13 in the fractures group and 17 in the non-fracture group (p=1.000), and eight cases were graded as failures (2 cases of grade 1 and 6 cases of grade 2). There were also no significant differences between these two groups in premature physeal arrest (2 in fracture group and 1 in non-fracture group, P=0.562), and Coxa vara (3 in the fracture group and 0 in non-fracture group, P=0.066). Pathological fracture significantly increases the risk of unsatisfactory functional results and avascular necrosis of the femoral head in patients with femoral neck SBCs. Prophylactic treatment and fixation of SBCs in weight bearing proximal femur region is better to manage without complications than managing with pathological fractures. [ABSTRACT FROM AUTHOR]

INTRODUCTION: Proximal femur resection and endoprosthetic reconstruction is the preferred treatment for extensive bony destruction and pathological fractures. Due to the relatively high cost of endoprosthesis, we adopted the modified unipolar hemiarthroplasty (MUH) for reconstruction when the mode of treatment was for palliation. MATERIALS AND METHODS: This is a retrospective case study of six patients, who had bone and multi-organs metastases with extensive proximal femur involvement with pathologic fractures who underwent resection and MUH reconstruction during the period 2013 to 2017. All patients were classified as Group B / C based on Scandinavian Sarcoma Group survival scoring, with estimated survival of maximum six months. The basic MUH construct consisted of AustinMoore prosthesis which was secured to a Küntscher nail using cerclage wire and cemented into the femoral canal. Subsequently, the whole length of the prosthesis which remained outside the canal was coated with cement. RESULTS: The mean age was 61.8 years. The mean survival was 3.9 months, post-operation. There was no implant failure during patients’ life span; however, a third of the patients developed infection. Wheel chair ambulation was started immediately post-operation for all patients, and two patients progressed to walking frame ambulation. The total cost of each construct was below US$490 in comparison to long-stem hemiarthroplasty (roughly US$ 1700). CONCLUSION: Our aim was to alleviate pain, facilitate rehabilitation, ease nursing care and improve quality of life for metastatic bone disease patients until end of life. MUH for the treatment of pathological fracture in proximal femoral metastases is a feasible palliative surgical modality in resource-limited settings.

Abstract Background The optimal reconstructive method after diaphyseal malignant bone tumor resection remains controversial. This multicenter clinical study was designed to investigate the clinical value and complications of segmental prosthesis in the repair of diaphyseal defects. Methods We present 49 patients from three clinical centers treated with wide resection for primary or metastatic bone tumors involving the diaphysis of the femur, tibia, humerus, or ulna, followed by reconstruction using a modular intramedullary segmental prosthesis. Results Enrolled patients included 23 men and 26 women with a mean age of 63.3 years. Of these, seven patients had primary bone tumors and 42 patients had metastatic lesions. At the mean follow-up of 13.7 months, 17 patients were alive, 31 patients were deceased due to tumor progression, and one patient was dead of another reason. There were eight nononcologic complications (two with radial nerve injury, three with delayed incision healing, two with aseptic loosening in the proximal humerus prosthetic stem and one with structural failure) and three oncologic complications (three with primary tumor recurrence) among all patients. The incidence of complications in primary tumor patients (4/7, 57.1%) was higher than that in patients with metastatic tumors (7/42, 16.7%) (p = 0.036). Aseptic loosening and mechanical complications were not common for patients with primary tumors, although the reconstruction length difference was statistically significant (p = 0.023). No statistically significant differences were observed in limb function, while the mean musculoskeletal tumor society score was 21.2 in femora, 19.6 in humeri, and 17.8 in tibiae (p = 0.134). Conclusions Segmental prostheses represent an optional method for the reconstruction of diaphyseal defects in patients with limited life expectancy. Segmental prostheses in the humerus experienced more complications than those used to treat lesions in the femur.

Objective: Osteoporosis is a progressive systemic skeletal disease characterized by increasing susceptibility to fractures. The current study was conducted to assess the awareness about osteoporosis among the general population in the Northern Border region of Saudi Arabia to improve awareness and proper planning for public awareness about osteoporosis., Methods: The study was conducted as a cross-sectional survey study, based on the online distribution of the Arabic-translated Osteoporosis Knowledge Assessment Tool (OKAT). The questionnaire questions cover the demographic characteristics of the participants, as well as symptoms, risk factors, prevention, and knowledge of treatment centers for osteoporosis in Saudi Arabia., Results: 395 participants were enrolled in the study after their informed consenting. After scoring all correct answers for each participant, the mean score of all participants' answers was 12.5±3.4 (range 0-19). Participants with poor knowledge (0-7 scores), moderate knowledge (8-13 scores), and good knowledge (13-20 scores) represent 61 (15.4%), 213 (53.9%), and 121 (30.6%), respectively. The mean percentage of right answers to all the questions is 44.1%. The highest awareness level was shown in the area of osteoporosis symptoms and risk of fractures, while the lowest was recorded in the questions covering the risk factors. Ages, genders, jobs, and levels of education significantly affected the participants' levels of awareness., Conclusion: The public awareness among the population in the Northern Border region about osteoporosis is less than satisfactory. More awareness activities targeting the risky groups should be planned especially in the area of risk factors and preventive measures for osteoporosis., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Elmorsy et al.)

Osteoradionecrosis of the jaw can be treated using both conservative treatment and surgery. External fixation may be used to bridge large resection defects after sequestrectomy for stabilisation and before secondary mandibular reconstruction. We designed a retrospective analysis of 70 patients with osteoradionecrosis treated between the years 2014 and 2018, and found that the use of external fixation greatly improves their outcomes. Patients were grouped according to Notani's classification: those who had Notani I disease were treated surgically but without external fixation; and those with Notani II and Notani III disease were eligible for external fixation. In those with Notani II disease, there was a significant reduction in the number of pathological fractures that occurred with external fixation. In those with Notani III disease, the success rate of primary sequestrectomy was only 1:14; however, those treated with external fixation all successfully healed after their first operation. It was hypothesised that although external fixation would improve outcome, it would come at a detriment to their quality of life (QoL). However, in a subset of these patients, we showed that in addition to increasing successful healing, patients' QoL with the external fixator was no worse than when they had an active osteonecrotic lesion. The treatment of osteoradionecrosis is cumbersome and advanced stages are associated with more complications. The use of an external fixator significantly reduces the probability of pathological fractures and increases the rate of successful healing in patients after mandibular resection. It does this without greatly interfering with patients' lives, while improving their condition sufficiently to allow for subsequent mandibular reconstruction. [ABSTRACT FROM AUTHOR]

Introduction: Management of pathological fractures of the proximal femur is often challenging. Compound double-plate osteosynthesis has been specifically developed for surgical treatment of these pathological fractures. To our knowledge, this study represents the largest series to date of double-plate compound osteosynthesis with the longest follow-up.Materials and Methods: Using our institutional digital database, we identified 61 procedures in 53 patients at the proximal femur. Patients were divided into two groups. A 'primary' group with all cases in which a double-plate compound osteosynthesis was performed as initial procedure (n = 46) and a 'revision' group with all cases in which a double-plate compound osteosynthesis was performed as revision procedure after failed previous attempts of internal fixation (n = 15). (1) The survivorship of the hip was calculated using the Kaplan-Meier survivorship analysis. (2) Complications were graded using Sink's classification. (3) The functional outcome was quantified with the Merle d'Aubigné and Postel score. (4) Risk factors were identified based on a multivariate Cox-regression analysis.Results: The cumulative Kaplan-Meier survivorship of the primary group was 96% at 6 months, 90% at 1 year, 5 years and thereafter and 83% at 6 months, 74% at 1 year, 53% at 2 years for the 'revision' group (p = 0.0008). According to the classification of Sink et al., the rate of grade III and IV complications was significantly lower in the primary group (p < 0.0001). The mean Merle d'Aubigné score was 14 ± 7 at 0-3 months, 13 ± 3 at 3-6 months, 15 ± 3 at 6-12 months and 15 ± 4 thereafter (p = 0.54). The only multivariate negative predictor was previous surgery with a hazard ratio of 9.2 (p < 0.006).Conclusion: Double-plate compound osteosynthesis is a valuable treatment option for pathological fractures in proximal femur with good functional results.

Pathological fractures (PFs) are common in patients with spina bifida. However, most previous studies refer to the overall fracture rate and largely neglecting putative age-dependent aspects. The aim of this retrospective study was to characterize patterns of fracture occurrence in childhood. In a retrospective study, we identified PF, all in the lower limbs, in 13% of 210 patients with spina bifida aperta. We further identified a bimodal frequency distribution of pathological fractures, with peaks at 1-5 and 10-12 years. We could thereby distinguish two groups of patients: (i) Children with a first fracture before an age of 6 years developed frequently multiple fractures within the following years, but fracture series typically stopped by 6 years-of-age. (ii) Children with a first fracture after the age of 6 years had fewer fractures, but these occurred also in adolescence. PF occurred rarely after the age of 13 years. The age at fracture correlated with the fracture site with 85% of the fractures occurring in the femur in the first five years of life and an increased frequency of tibia and foot fractures later in life. While, overall high lesion levels and preceding immobilizing events were risk factors for PF, femur fractures in children under 6 years-of-age occurred independent of their lesion level, and the age at verticalization did not correlate with PF rates.Conclusion: Based on these findings, standardized and effective preventive physiotherapeutic and/or pharmacological interventions to tackle PF in spina bifida need to consider age-specific differences in occurrence and reoccurrence of fractures.What is Known:• Pathological fractures are common in patients with spina bifida aperta, and associated risk factors include high lesion level, immobilization and low bone density.What is New:• We first report a bimodal frequency distribution of pathological fractures in childhood (first peak 1-5 years, second peak 10-12 years) and link early-onset fracture occurrence with the risk of multiple fractures arise in a short time period but a the chance of self-limitation of fracture series within a few years.• We show that femur fractures in children under 6 years-of-age occurred independent of their lesion level, and the age at verticalization did not correlate with PF rates.• We further link the age-dependent occurrence pattern with the risk of further fractures and with the chance of self-limitation of fracture series. The earlier a first fracture occurs, the more probable multiple fractures arise in a short time period. Nevertheless, early fracture series are often self-limiting within a few years.• Femur fractures in children under 6 years-of-age occurred independent of their lesion level, and the age at verticalization did not correlate with PF rates.• Based on these findings, physiotherapeutic and/or pharmaceutical concepts need to be developed in an age-adapted manner and in consideration of the potential self-limiting nature of fracture series.

Background: Vertebral cement augmentation and external beam radiotherapy have become increasingly used techniques for treatment of vertebral compression fractures due to spinal metastatic lesions in the Republic of Moldova. Surgically, the goal of vertebral cement augmentation is to improve the strength and stability of the injured vertebrae, as well as local tumor control. External beam radiotherapy for suppressing tumor or inducing pain relief are performed immediately after vertebral cement augmentation. Usually, local tumor control is occurred by CT or MRI studies. We have studied through the infrared thermography the dynamics of temperature gradient of tumoral foci skin projection. Material and methods: The purpose of this study is to evaluate the local tumoral control, analyzing the infrared thermographic examinations in 33 patients with uncomplicated metastatic vertebral fractures, undergoing combined method of treatment (vertebral cement augmentation + external beam radiotherapy), before the treatment and at 12 months follow-up. Results: We observed an indirect tumor “thermographic field” decrease registered by temperature gradient decrease from an average of 2.03±0.24ºC in preoperatively to 1.28±0.33ºC at 12 months postoperatively follow-up. Conclusions: Combined method of stabilization (vertebral cement augmentation + external beam radiotherapy) in patients with uncomplicated metastatic vertebral fractures is effective in minimal invasive surgery and offering local tumor control.

Primary hyperparathyroidism (PHPT) is rare in children and adolescents, but has greater morbidity in this age group. Most of these patients show predominantly skeletal pathology and to a lesser extent renal involvement. Osteopenia, osteoporosis and subperiosteal resorption are frequently encountered radiographic skeletal signs. This study describes the orthopedic manifestations of PHPT in a child. PHPT in this child exhibited a late presentation with significant clinical morbidity and extensive radiographic manifestations. The characteristic radiographic pattern of PHPT in childhood is an important contributor to the diagnosis. The radioclinical and biochemical correlations augment diagnostic accuracy and delineate extent of skeletal pathology.

The diagnosis of pathological fractures is on the rise. The morbidity involved does not only burden the patient and their families but it has a great toll on the healthcare system as well. Early identification of the patient at risk is an invaluable tool to cut cost and improve the patient’s quality of life. Multiple renal pathologies have been highlighted in relation to the risk of pathological fractures; however, complications in renal tubular acidosis have been rarely documented. Nevertheless, prompt action with adequate and relevant patient education ultimately can reduce the associated morbidity. We present a case of poor control of the disease and its debilitating pathological fracture complications.

Background: The optimal reconstructive method after diaphyseal malignant bone tumor resection remains controversial. This multicenter clinical study was designed to investigate the clinical value and complications of segmental prosthesis in the repair of diaphyseal defects.Methods: We present 49 patients from three clinical centers treated with wide resection for primary or metastatic bone tumors involving the diaphysis of the femur, tibia, humerus, or ulna, followed by reconstruction using a modular intramedullary segmental prosthesis.Results: Enrolled patients included 23 men and 26 women with a mean age of 63.3 years. Of these, seven patients had primary bone tumors and 42 patients had metastatic lesions. At the mean follow-up of 13.7 months, 17 patients were alive, 31 patients were deceased due to tumor progression, and one patient was dead of another reason. There were eight nononcologic complications (two with radial nerve injury, three with delayed incision healing, two with aseptic loosening in the proximal humerus prosthetic stem and one with structural failure) and three oncologic complications (three with primary tumor recurrence) among all patients. The incidence of complications in primary tumor patients (4/7, 57.1%) was higher than that in patients with metastatic tumors (7/42, 16.7%) (p = 0.036). Aseptic loosening and mechanical complications were not common for patients with primary tumors, although the reconstruction length difference was statistically significant (p = 0.023). No statistically significant differences were observed in limb function, while the mean musculoskeletal tumor society score was 21.2 in femora, 19.6 in humeri, and 17.8 in tibiae (p = 0.134).Conclusions: Segmental prostheses represent an optional method for the reconstruction of diaphyseal defects in patients with limited life expectancy. Segmental prostheses in the humerus experienced more complications than those used to treat lesions in the femur. [ABSTRACT FROM AUTHOR]

Introduction: Magnetic resonance imaging (MRI) is the radiological modality of choice for diagnosing pathological fractures in situations of diagnostic uncertainty. With the increasing availability of MRI, we have observed a disturbing trend in utilising routine MRI scans to exclude pathological fractures in all patients with a history of cancer. The study objective was to determine if routine use of MRI scans in such patients is truly necessary and if other predictive factors can be utilised in lieu of the MRI scan.Materials and Methods: A 3-year retrospective study was conducted reviewing all extremity MRI scans performed for suspected pathological fractures and compared to X-rays. All patients presented with an extremity fracture, a known diagnosis of solid organ cancer and had an MRI to determine if the fracture was pathological. Subjects were followed up with serial X-rays up to 1 year.Results: 84 subjects were recruited. Comparing X-rays alone with MRI scans revealed 92% sensitivity and 98% specificity in detecting pathological fractures. Using X-rays in combination with an absent history of trauma increases the sensitivity to 100% but reduced the specificity to 91%. None of subjects in cancer remission had pathological fractures.Conclusions: MRI is an imperative tool for operative planning in pathological fractures; however, we recommend against the routine use of MRI to diagnose pathological fractures in oncological patients. Patients with solid organ cancer remission, a positive history of significant trauma prior to sustaining the fracture, and the absence of pathological features on plain radiographs are strongly predictive against pathological fractures.

Purpose of the study: to evaluate osteogenic rate of various characteristics of mechanical loading based on the authors’ data as well as literature analysis.Literature analysis proved that clinical outcome of physical training can be achieved not only by increasing the mechanical load but also by altering number of load iterations, rate of load acceleration, frequency of cyclic load, rest interval, distribution of load across the skeleton. Presented data provides a reasonable basis to apply alterations of all above-mentioned load characteristics to obtain clinical effect and customize every single baseline exercise plan to gain a maximum treatment and preventive effect in individuals with high risk of osteoporotic fractures.

Prostate cancer (PC) is one of the most urgent problems of modern oncourology. Morbidity and mortality from this disease in theRussian Federationin recent years has been steadily increasing. Including the number of patients with metastatic and refractory to castration therapy forms of the disease is increasing. Currently, the main method of treatment of patients with metastatic prostate cancer is palliative hormone therapy (HT). Patients who have progression of tumor process, with lingering castration levels of testosterone, transferred to the stage of so-called castrate-resistant prostate cancer (CRPC). The prognosis in this group of patients is extremely unfavorable, not only because of the progression of cancer, but of complications associated primarily with the presence of bone metastases. Prevention of development of serious complications such as pathological fractures, spinal cord compression is an extremely important issue. The article presents a review of studies, the sanctifying of the problem of prevention of development of bone complications in patients with CRPC. We resent the results of large studies, including those conducted in our country demonstrated the effectiveness zoedronic acid in patients with CRPC and the presence of bone metastases.
