Operative treatment of chondroblastoma: a study of 11 cases.

Aim of the study was to review the radiological, clinical results of 11 chondroblastoma cases treated at our institute between 2003-2013. All patients with chondroblastoma included in this study underwent intra-lesional curettage+/-bone grafting. Follow up for healing of chondroblastoma lesions and detection of any local recurrence was assessed on clinical and radiological bases. The functional outcome was assessed by the Musculoskeletal Tumour Society scoring system. The mean follow-up period was 6.1 years. There were three recurrences (two femoral head, one proximal tibia). The mean Musculoskeletal Tumour Society functional score was 21. First line aggressive treatment seems appropriate for chondroblastoma especially when localized at lower extremities.

Coexistence of Extraskeletal Mesenchymal Chondrosarcoma and Isolated Hemihyperplasia: A Case Report.

INTRODUCTION: Arthroscopic fixation of tibial spine fracture without damage to the growth plate is very important in patients with open physis. The present article describes a simple and effective technique being used for the first time to treat this condition. CASE REPORT: A 16-year-old boy sustained avulsion fractures of tibial spine while playing. He was treated arthroscopically with excellent result. CONCLUSION: Arthroscopic fixation of tibial spine fracture in patients with open physis with two cannulated screws perpendicular to each other is a very simple technique which provides strong construct, and allows early mobilization without risk of damage to the growth plate.

Dermal argyria: Cutaneous manifestation of a megaprosthesis for distal femoral osteosarcoma.

We present a patient with dermal argyria as a cutaneous manifestation of a silver-coated megaprosthesis used for a distal femoral osteosarcoma. Histological and electron microscopic analyses also showed silver deposition in the dermis.
