A rare presentation of recurrent chondroblastoma of scapula, acromion and lateral end of clavicle.

About 1% of primary bone tumours are chondroblastoma, which develop from secondary ossification centers of long bones, preferably. The scapula, clavicle, and acromion are the rarest sites for this tumour. The recurrence rate is 14-18%, depending on the site of origin. There are various treatment options, but extended curettage and bone grafting are the main treatment modalities for chondroblastoma. In cases of recurrence, marginal excision and wide local excision are the treatments used. Here we report a recurrent tumour in that location that was removed by wide local excision. After 2 years of follow-up, there were no signs or symptoms of recurrence noted. This case is notable for its rare site of occurrence and successful surgical management without any episodes of re-occurrence after a 2-year follow-up period.

Mechanical thromboprophylaxis for hip fractures in elderly patients: a prospective randomized controlled study.

BACKGROUND: Hip fractures, most common in the geriatric age group, can develop proximal deep vein thrombosis (DVT). There is no consensus regarding the ideal method or duration of prophylaxis, particularly in a trauma patient. This study bridges this lacuna in data by making a random comparison between mechanical prophylaxis alone vis-a-vis combined with mechanical and Enoxaparin-based chemoprophylaxis. MATERIALS AND METHODS: 75 Elderly hip trauma patients from January 2019 to October 2020 at a single tertiary care center were randomly allocated into two groups using the sequentially numbered opaque sealed envelope method (SNOSE): one (n=44) receiving Enoxaparin and Mechanical prophylaxis and another (n=31) receiving Mechanical prophylaxis alone. All patients underwent CT (computed tomography) venography to screen for proximal DVT between days 5 to 10 of injury. The primary outcomes were the incidence of proximal DVT and pulmonary embolism (PE), and safety outcomes (wound complications and adverse systemic events) were recorded during the treatment. RESULTS: No symptomatic or asymptomatic proximal DVT and death incidence was reported in either group. One case of pulmonary embolism was seen in the combined prophylaxis group. There was no significant difference between the groups regarding the above-mentioned parameters mentioned. CONCLUSIONS: There is no significant difference in the incidence of proximal DVT between mechanical alone and combined chemical-mechanical prophylaxis in elderly patients sustaining hip trauma. The incidence of proximal DVT can be reduced by mechanical prophylaxis alone. It was efficacious and safer than combined mechanical and enoxaparin prophylaxis in preventing venous thromboembolism in elderly hip trauma patients.

Primary Synovial Chondromatosis of the Ankle in a Child: A Rare Case Presentation and Review of Literature.

Introduction: Synovial chondromatosis is not a common condition and involvement of the ankle joint is quite rare. We found only one case of synovial chondromatosis of the ankle joint among the pediatric population. We present a case of a 9-year-old boy with synovial chondromatosis of the left ankle. Case Report: A 9-year-old boy had synovial osteochondromatosis in the left ankle joint, which caused pain, swelling, and restriction of movement of the left ankle. Radiological examinations showed variable size calcific foci adjacent to the medial malleolus and medial ankle joint space with mild soft-tissue swelling. The ankle mortise space was well-maintained. The magnetic resonance imaging of the ankle joint revealed a benign synovial neoplastic process and a few focal marrows containing loose bodies. The synovium was thick, and there was no articular erosion. The patient was planned and underwent an en bloc resection. A lobulated pearly white mass arising from the ankle joint was observed intraoperatively. Histological examination also showed attenuated synovium with osteocartilaginous nodule with binucleated and multinucleated forms of chondrocyte typical of osteochondroma were appreciated. Endochondral ossification, mature bony trabeculae with intervening fibro adipose tissue, was noted. The patient had remarkable relief of clinical complaints and was almost asymptomatic at the time of the first follow-up. Conclusion: Synovial chondromatosis may present with diverse clinical manifestations according to the different stages of the disease as described by Milgram; like joint pain, limitation of movements, swelling due to the close proximity of important structures including joints, tendons, and neurovascular bundles. A simple radiograph with a characteristic appearance is usually sufficient in confirming the diagnosis. In pediatric patients, overlooking these conditions may result in growth abnormality, skeletal deformities, and several mechanical problems. We suggest that when dealing with the case of swelling in or around the ankle, the differential diagnosis should include synovial chondromatosis.

Impact of the COVID-19 Lockdown and Confinement Measures on the Musculoskeletal Health of the Urban Geriatric Population.

Background Owing to the coronavirus disease 2019 (COVID-19) pandemic, a nationwide lockdown was imposed in India, with strict confinement measures imposed on the elderly. Because mobility and regular physical activity are considered to be the key determinants of musculoskeletal health, this study aimed to investigate the effect of lockdown and confinement measures on the musculoskeletal health and activities of daily living of the urban geriatric population. Methodology A cross-sectional survey was conducted among the elderly aged ≥60 years. The survey instrument consisted of a questionnaire, a modified Nordic Musculoskeletal Questionnaire (mNMQ), and the Barthel activities of daily living (ADL) index. The net mNMQ score and Barthel ADL index were compared before and during the lockdown. Univariate and multivariate analyses were performed to determine which factors could result in the worsening of the net mNMQ score. In addition, floor and ceiling effects of the net mNMQ score were determined. Results In this study, a total of 105 out of 150 eligible participants were enrolled. A significant decline in physical activity status was noted during the lockdown. Overall, 54.3% of the respondents reported that their medical services were impacted during the lockdown. The net mNMQ score showed a significant worsening during the lockdown (P < 0.0001). A statistically significant increase in the modified NMQ score was noted for the lower limb (P < 0.0001) and spine (P = 0.002), but not for the upper limb (P = 0.052). Elderly whose medical services were impacted during lockdown had significantly worse net mNMQ scores than those whose services were not impacted (odds ratio = 6.16; 95% confidence interval = 2.51-15.08; P = 0.0001). Age, gender, ambulatory status, increase in body weight, and indulgence in exercise before and during lockdown had no effect on the change in the net mNMQ score. A significant ceiling effect was noted in the mNMQ score; however, no floor effect was noted. Conclusions Lockdown and confinement measures resulted in a significant decline in physical activity as well as the overall musculoskeletal health of the urban geriatric population in the present study. Hence, policymakers should ensure uninterrupted medical care to the elderly during extended periods of confinement and develop optimal home-based physical activity programs to counter the problems associated with sedentarism.

Patellar Osteoid Osteoma as a Cause of Intractable Anterior Knee Pain - A Case Report and Systematic Review of Literature.

INTRODUCTION: Patellar involvement by osteoid osteoma is very rare. Osteoid osteomas that present as anterior knee pain are frequently misdiagnosed which leads to initial delay in treatment. Plain radiology has poor diagnostic yield. A combination of high index of suspicion, appropriate imaging, and complete ablation of the lesion is necessary to achieve good outcomes. CASE REPORT: A 16-year-old male presented with insidious onset anterior knee pain for the past 2 years. The pain was intermittent and mild; however, it increased progressively in intensity and frequency, which was worse at night. Examination reveals minimal effusion in the suprapatellar pouch, full range of motion of the knee, and wasting of the quadriceps. Serum biochemistry parameters were in normal limits. Plain radiographs did not reveal any significant abnormality. On magnetic resonance imaging, a hypointense, punctate lesion surrounded by a small hyperintense zone was noted at medial aspect of patella. A computed tomography scan showed the lesion with a central nidus, surrounded by a sclerotic rim, confirming the diagnosis of osteoid osteoma. Radiofrequency ablation was carried out without any post-procedural complications. The patient was pain free a few days after the procedure. At 14-month follow-up, there was no recurrence of symptoms. CONCLUSION: Osteoid osteomas that present as anterior knee pain are frequently misdiagnosed. Plain radiology has poor diagnostic yield. A combination of high index of suspicion, appropriate imaging, and complete ablation of the lesion is necessary to achieve good outcomes.

Bilateral sub-trochanteric femur fragility fractures in a patient on antiretroviral therapy: a case based discussion and review of literature.

BACKGROUND: The burden of HIV/AIDS is ever increasing, affecting populations all over the world. Along with the disease, its effects and consequences on bone health are also on a rise. A commonly used drug in managing HIV, "Tenofovir" has been shown to affect bone health, specifically on prolonged usage. Osteomalacia and osteoporosis secondary to drug induced Fanconi syndrome and the disease itself, could lead to pathological/fragility fractures with trivial trauma. CASE DESCRIPTION: A 45 year old female on antiretroviral drugs (ART) for HIV, presented with right hip pain and inability to bear weight. She has had similar symptoms previously in the left hip which resolved after 6 weeks of limited weight bearing. Anteroposterior and lateral radiographs of pelvis with hips showed bilateral sub-trochanteric fractures; healed on the left side and displaced on the right side. The patient was managed with cessation of tenofovir and right side proximal femoral nail anti-rotation (PFNA). Patient was lost to follow up but had started to ambulate independently with a cane, by the end of 6 weeks, before she succumbed to systemic complications. CONCLUSION: Patients receiving antiretrovirals especially tenofovir should be regularly investigated for their renal impairment and bone health. Fixation of pathological fractures and early mobilization are important to prevent prolonged bed immobilization and associated complications in these immunocompromised patients.

Four Screws Diamond Configuration Fixation for Displaced, Comminuted Intracapsular Fracture Neck Femur in Young Adults.

BACKGROUND: Four cannulated cancellous screws (CCS) in diamond configuration have been recommended by some authors for fixation of intracapsular neck of femur (ICNF) fracture with posterior comminution in adults. This is also supported by biomechanical studies. However, the clinical usefulness of this biomechanical advantage is not known. This study evaluates the outcomes of displaced, comminuted ICNF fracture in young adults managed by four CCS fixation in diamond configuration. MATERIALS AND METHODS: 25 patients who met the inclusion criteria were operated during the study period. Four patients were lost to followup in the first 6 weeks postoperatively, and one patient died in first 6 months of followup unrelated to surgery. Thus, twenty patients were followed up for a mean period of 33.3 months (range 25-38 months). In all patients, fracture fixation was done with four CCS in diamond configuration. Union at fracture site and avascular necrosis (AVN) of femoral head was assessed on serial plain radiographs. Functional outcome was evaluated by Harris hip score. RESULTS: Eighteen patients had union, two patients had nonunion, and two patients had AVN of femoral head. All the sixteen patients who had union without AVN had good or excellent functional outcome. CONCLUSIONS: The present study concludes that four CCS fixation in diamond configuration appears to be a reasonable choice of fixation for displaced fracture ICNF with comminution in young adults. However, further evaluation with better study design and larger patient population is required for definite conclusions.

Outcome of bone marrow instillation at fracture site in intracapsular fracture of femoral neck treated by head preserving surgery.

PURPOSE: The aim of present study is to evaluate the outcome of bone marrow instillation at the fracture site in fracture of intracapsular neck femur treated by head preserving surgery. METHODS: This study included 32 patients of age group 18-50 years with closed fracture of intracapsular neck femur. Patients were randomized into two groups as per the plan generated via www.randomization.com. The two groups were Group A (control), in which the fracture of intracapsular neck femur was treated by closed reduction and cannulated cancellous screw fixation, and Group B (intervention), in which additional percutaneous autologous bone marrow aspirate instillation at fracture site was done along with cannulated cancellous screw fixation. Postoperatively the union at fracture site and avascular necrosis of the femoral head were assessed on serial plain radiographs at final follow-up. Functional outcome was evaluated by Harris hip score. RESULTS: The average follow-up was 19.6 months. Twelve patients in each group had union and 4 patients had signs of nonunion. One patient from each group had avascular necrosis of the femoral head. The average Harris hip score at final follow-up in Group A was 80.50 and in Group B was 75.73, which was found to be not significant. CONCLUSION: There is no significant role of adding on bone marrow aspirate instillation at the fracture site in cases of fresh fracture of intracapsular neck femur treated by head preserving surgery in terms of accelerating the bone healing and reducing the incidence of femoral head necrosis.
