A Rare Case of Melorheostosis Presenting with Extra-osseous Lesions Around the Knee: Case Report.

Introduction: Melorheostosis was initially identified in 1922 by Leri and Joanny. It is often referred to as candle bone disease, melting wax syndrome, or Leri disease. This mesenchymal condition is uncommon, benign, and non-heritable. There is still a lack of clarity regarding the underlying cause of the condition. The estimated incidence is 0.9% per million. No inherited traits have been identified, and both sexes are equally affected. Pain or swelling is the most typical symptoms, and the onset is insidious. People often call this condition "candle disease of the bone" because the radiological signs of it look like dripping candle wax. Case Report: A 56-year-old female presented with an 8-year history of the left knee pain, swelling, and movement restriction. On examination, a hard, bony lump measuring 12×5 cm was located on the outer aspect of the left knee. The skin over the lump's surface was neither erythematous nor warm. Plain radiographs revealed a wide, dense, undulating, or irregular cortical hyperostosis, resembling candle wax, spreading along the length of the fibula bone as well as an extra-osseous calcification mass across the lateral aspect of the left knee. The patient underwent excision with complete left knee motion. Conclusion: Melorheostosis' actual etiology is yet unknown. There is no established treatment for this condition. Only symptomatic treatment helps patients feel better; in some circumstances, the excision of a bone mass yields more beneficial results.

Functional Outcomes After Discectomy for Recurrent Lumbar Herniation Using the Destandau Endospine System: A Retrospective Study of 44 Patients.

Background Recurrent disc herniation is a major cause of morbidity and surgical failure after disc surgery. This study aimed to investigate the feasibility, safety, and effectiveness of the Destandau endospine system (DES) for treating recurrent lumbar disc herniation (LDH). Methodology A total of 44 patients who underwent minimally invasive Destandau endoscopic lumbar discectomy (DELD) for recurrent LDH were included in this study. All data were collected retrospectively. The preoperative and postoperative visual analog scale (VAS) score was used for the evaluation and gradation of pain. The clinical outcome was analyzed according to modified MacNab criteria. The minimum follow-up was two years. Preoperative and postoperative VAS scores were compared using the paired Student's t-test. Statistical significance was set at a p-value <0.05. Results The mean surgical time was 30 ± 20 minutes. The VAS score for leg pain was improved in all cases from 5.9 ± 2.1 to 1.7 ± 1.3 (p< 0.001). In 98% of cases, a successful outcome was noted (excellent or good outcome according to MacNab criteria). In three (7%) patients, incidental durotomy occurred, but there was no neurological worsening, cerebrospinal fluid fistula, or negative influence on the clinical outcome. No recurrence or instability occurred in our series. Conclusions The clinical outcomes of minimally invasive DES for LDH were found to be comparable with the reported success rates of other minimally invasive techniques reported in the existing literature. The dural tear rate was independent of postoperative morbidity and functional outcome. The technique is a safe and effective treatment option for recurrent LDH.

Functional and Radiological Outcome in Atypical Subtrochanteric Femur Fracture After Surgical Fixation: A Retrospective Observational Study.

BACKGROUND: Treatment for osteoporosis can have catastrophic side effects, including the uncommon fracture known as an atypical femur fracture (AFF), which is related to the long-term usage of antiresorptive agents. Bisphosphonate therapy may lead to significant and chronic suppression of bone turnover, impairing the bone's remodelling property and finally leading to incomplete or complete atypical femur fracture. AFF was defined by the American Society for Bone and Mineral Research (ASBMR) Task Force in 2010 and is far less prevalent than proximal femur (hip) fracture, with an incidence of 2 to 78 per 100,000 patients per year following two to eight years of bisphosphonate therapy, respectively. Due to the rarity of the fracture, it is still not clear what the functional and radiological outcome will be after surgery. AIM: To identify the functional and radiological outcomes of surgical fixation of atypical femur fractures. METHODS: The study was conducted in a tertiary healthcare centre after scientific and ethical clearance from the competent authority. Between January 2018 and December 2021, individuals who were diagnosed with an atypical subtrochanteric femoral fracture associated with the use of bisphosphonates and treated surgically were retrospectively evaluated. The study's inclusion and exclusion criteria were used to include 20 patients. The features of an atypical subtrochanteric fracture were congruent with the radiographic findings. Most of the patients were treated with internal fixation with intramedullary osteosynthesis in standard with or without plate osteosynthesis. They were then followed up for a year to look at the functional and radiological outcomes. RESULTS: All of the 20 patients who were included had an atypical subtrochanteric fracture, with 15 of them being female and 5 of them being male. The patients' mean age at surgery was 65.12 (range 49 to 82) years, and their average history of bisphosphonate use was 3 (range 2.5 to 5) years. All patients were treated surgically. We found that five months was the mean period for bone union (p = 0.990). Within six months, bone union was achieved in 11 patients (55 %) (p = 0.884). Five patients (about 25%) had implant failure and non-union, requiring two to three revision surgeries. At three, six, and nine months, the mean visual analogue score (VAS) was 4.14, 3.12, and 1.85, respectively. The modified Hip Harris Score had a mean of 72.66 and 15 patients (about 75% of them) could walk normally again after a fracture. The mean of the modified HHS was 72.66, and the VAS at three, six, and nine months was 4.14, 3.12, and 1.85, respectively. CONCLUSION: AFFs are rare fractures that must be treated effectively, and most of them require surgery. Successful treatment of AFF is possible by the use of intramedullary fixation, which enhances axial stability, serves as an internal splint, and lessens the likelihood of implant failure. A good functional and radiological prognosis can come from a stable fixation and a fracture that has been reduced anatomically.

Metastatic Adenocarcinoma of Lungs, Mimicking Primary Scapular Tumor: A Case Report and Review of Literature.

Introduction: Cancer metastasis to the scapula and tibia is an infrequent clinical presentation. Lung cancer is one of the leading causes of death in the world. Around 80-85% of lung cancer are non-small cell lung cancer and around 30-35% of them are adenocarcinoma which metastasize to bone. Scapular metastasis is a rare event and presents with bone pain. Case Report: In this case report of 56-year-old male, presented with swelling to the scapula as a first symptom followed by swelling in the tibia. On further investigation, it was found to be multiple metastasis primaries as an adenocarcinoma of the lung. He was managed with palliative chemotherapy, which enhanced the patient's quality of life, slowing down the disease process and clinical improvement. Conclusion: Lung cancer is the most common cancer which is progressing rapidly and spreading commonly to bones. When patients present with a mass or any suspicion of tumor, careful clinical examination and diagnostic tools often catch malignancy.

Short-Term Functional Outcome and Satisfaction Rate of Unicompartmental Knee Arthroplasty in Indian Population: A Retrospective Study.

INTRODUCTION: Unicompartmental knee arthroplasty (UKA) is a procedure used to treat isolated medial or lateral compartmental osteoarthritis of the knee joint. This procedure involves retention of cruciate ligaments which leads to better functional outcome due to preservation of normal kinematics of the knee joint. In the Indian population, due to requirement of squatting and cross leg sitting habits, knee with more range of movement and with good kinematics is a required feature. The study aims to observe the functional outcome, mortality, revision rate, length of hospital stay and satisfaction rate in two-year postoperative patients in a tertiary health care centre. METHODS: A total of 17 knees of 15 patients were recruited for the study after applying strict inclusion and exclusion criteria. These patients were operated during the period from March 2015 to March 2018. Ten female patients (67%) and five males (33%) were included. The average age was 61 years. All operations were performed by a single surgeon, with a similar implant from a single company. Similar protocol was used both for surgical technique (minimal invasive) and postoperative rehabilitation for all the patients. RESULTS: The functional outcome in the form of Oxford Knee Score (OKS) and Euro-Quol (EQ-5D) scores improved significantly in all the patients at one year postoperatively, and the improvement remained significant for two years. Satisfaction rate was 91.7% (SD-12.8) at two years. Except for one patient (5.8%), all patients were able to cross leg and squat easily. At the end of two years, the overall survival rate of the implant was found to be 94.1%. CONCLUSION: The unicondylar arthroplasty provides excellent satisfaction to the appropriately selected patients with good survivorship of implant. It can be a surgery of choice for Indian population as it restores normal kinematics of knee joint and allows the patient to cross leg and squat with a more range of movement.

Giant Cell Tumor of Third Metacarpal: A Rare Case Report and Review of Literature.

INTRODUCTION: Giant cell tumor (GCT) or osteoclastoma is an osteolytic, mostly benign but locally aggressive tumor occurring in young adults at the meta-epiphyseal region of long bones such as lower end of the femur, upper end of the tibia, and lower end of the radius, and proximal humerus in descending order of frequency. Only 2% of all GCT of bone occur in hand. GCT of metacarpal (MC) has different characteristics than that of other long bones. It has more aggressive behavior with involvement of entire length of MC with soft tissue extension. CASE REPORT: We are reporting a case of GCT of the 3rdMC in a 19-year-old female. She presented to us with a painful, firm, ovoid, and gradually progressive swelling measuring 4 cm × 3 cm over the dorsum of the left (non-dominant)hand, since past 6 months. Fine-needle aspiration cytology was suggestive of GCT of the tendon sheath. Pre-operative magnetic resonance imaging and computed tomography scan revealed the extent of the lesion with no neurovascular involvement. Although various reconstructive procedures to salvage the affected Ray have been reported in literature, we planned for a surgical resection of the lesion leaving behind 1 cm of healthy MC base which appeared to be normal radiologically and intraoperatively. Reconstruction of the defect was done using non-vascularized contoured fibular strut graft, fixed with 2.5 mm mini reconstruction plate, along with reconstruction of the collateral ligaments of the metacarpophalangeal joint. The histopathological study confirmed the diagnosis of GCT. CONCLUSION: GCT of hand is a rare tumor, due to its relatively more aggressive behavior and high chance of recurrence it, nevertheless, provokes quite difficult issue to solve. Prognosis, treatment, and results are directly dependent on early diagnosis and adequate therapy.
