Rare Case of Bizarre Parosteal Osteochondromatous Proliferation of Foot.

Introduction: Nora's lesion or bizarre parosteal osteochondromatous proliferation (BPOP) is a rare, benign lesion of small bones of hands and feet in adults. It composed of differing amounts of cartilage, bone, and spindle cells and an unusual form of calcified cartilage so-called "blue bone". Case Report: A 23-year-old male presented with swelling at the lateral side of the fifth toe of his right foot, which was separated from the adjacent toe. Radiographs showed a mass arising from the proximal phalanx of the little toe, with no medullary and cortical continuity. Excisional biopsy of the mass was performed, and a histologic diagnosis of BPOP of bone (Nora's lesion) was made. Conclusion: This case presented with a cartilaginous cap around tumor which is suggestive for benign nature of this tumor with some histological variation from bizarre variant along with no recurrence which is unlikely seen in BPOP.

Short versus long proximal femoral nail in the management of intertrochanteric fractures - a comparative study.

INTRODUCTION: Intertrochanteric fractures are those that occur in the region spanning from the extracapsular basilar neck region to the region along the lesser trochanter proximal to the development of medullary canal. Low-energy falls account for 90% of fractures in people over the age of 50, with females having a higher prevalence. Intertrochanteric fractures in children and teenagers are caused by high-energy trauma. The aim of this study was to compare the functional and radiological outcomes as well as complications of intertrochanteric fractures treated with long proximal femoral nail (PFN) versus short proximal femoral nails. METHODS: The study was a clinical randomized prospective comparative study which included 30 (2 groups of 15 patients each, being treated with short and long PFNs respectively) skeletally mature patients with fresh (less than 3 weeks old) intertrochanteric fractures of femur AO/OTA 31-A1, AO/OTA 31-A2 or AO/OTA 31-A3 as per AO/OTA classification. Harris Hip score was used to compare the functional outcomes. RESULTS: The average age of patients in short PFN group (Group A) was 62.1 ± 15.77 years and in long PFN group (Group B), it was 54.1 ± 10.8 years. Male-female ratio in the study was 1.7:1. AO31A2 of AO fracture classification was the most common type of fracture in both the groups. The mean injury to surgery interval in Group A was 9.6 ± 4.45 days and in Group B, it was 6 ± 4.12 days. The mean operative duration in Group A was 68.6 ± 6.62 minutes and in Group B, it was 78.6 ± 7.35 minutes. The average time of union in Group A was 15.69 ± 2.72 weeks while that of Group B was 15.77 ± 2.05 weeks. The average Harris Hip score at final follow up in Group A was 81.0 ± 11.62 and in Group B, it was 80.3 ± 10.83. There was 1 case of implant failure in each group, which were re-operated. One case of screw back-out in Group A led to a varus collapse and had to be reoperated. One case of non-union was reported in Group B. One case of superficial wound infection was reported in each group. CONCLUSION: The Proximal Femur Nail can be used as an efficient implant to manage per trochanteric fractures regardless of the length of the implant. However, the mean operative time was found to be lower when a short nail is used.

Fixation using cannulated screws and fibular strut grafts for fresh femoral neck fractures with posterior comminution.

PURPOSE: To evaluate the use of fibular grafting for fresh femoral neck fractures with posterior comminution. METHODS: 18 women and 15 men aged 20 to 60 years underwent osteosynthesis and fibular strut grafting supplemented with 7.0-mm cannulated hip screws for Garden grades III (n=21) and IV (n=12) femoral neck fractures associated with posterior comminution. All fractures were reduced by closed methods, and no hip was aspirated. Clinical and radiological outcomes were evaluated. RESULTS: The mean delay in presentation after injury was 3.2 (range, 1-12) days. The mean delay in operation was 8.8 (range, 5-21) days. The mean follow-up period was 2 (range, 1-4) years. According to the Harris hip score, outcome was good to excellent in 20 patients, fair in 7, and poor in 6. 27 of the 33 patients achieved bone union after a mean of 4.7 (range, 4.2-7) months. In 5 patients, the bone was united with a mean of 10º of varus collapse and a mean of 1 cm of shortening. Six patients had non-union. Other complications included screw migration in the joint space (n=1), graft migration into the joint space (n=3), and screw pullout (n=5). No patient had avascular necrosis of the femoral head. CONCLUSION: Osteosynthesis and fibular grafting for freshly displaced femoral neck fractures with posterior comminution is an inexpensive and technically less demanding procedure for retaining a stable, painless, mobile, and functional hip.

Metachronous multicentric giant cell tumour of the upper extremity in a skeletally immature girl : A rare presentation.

Giant Cell tumour (GCT) or Osteoclastoma is a benign locally aggressive tumour with a tendency for local recurrence. Long tubular bones (75-90%) are frequent sites of involvement. GCT constitutes 5% of all primary bone tumours. Metachronous multicentric giant cell tumour of bone is a rare entity. Multicentric GCT, in contrast to unifocal GCT, has a tendency to involve the small bones of hands and feet, involving the metaphysis/diaphysis of long bones and tends to occur in a slightly younger population. We report a young girl presenting with metachronous multicentric recurrent benign GCT, with the lesions involving the ipsilateral right hand and distal humerus. She was successfully treated with an aggressive surgical approach (en-bloc resection).
