Osteoid osteoma is uncommonly located at the ankle joint level. Arthroscopic resection is an unusual treatment modality in this tumour situation. We report the case of a young man presenting with an osteoid osteoma of his talus neck. Diagnosis was made by MRI. Since the tumour was intraarticular and subperiosteal, it was arthroscopically removed. Pathological examination confirmed the diagnosis of osteoid osteoma. Recovery was uneventful; immediate and complete pain relief followed surgery and the patient remains asymptomatic several months after his operation. Arthroscopic techniques allow complete exploration of the joint and total excision of the tumour. This minimally invasive approach reduces infectious and functional risks (joint stiffness). Less invasive resection techniques should be advocated, when applicable, to achieve pathological diagnosis of the surgical specimen.

The study shows good intra- and interobserver reliability. The Lagrange and Rigault classification has similar reliability to other supracondylar fracture classifications.

We propose a distal radius reconstruction technique that provides a strong stable wrist while preserving mediocarpal range of motion. Two cases of giant cell tumor of the distal end of the radius were treated. The technique included en bloc resection of the lesion followed by wrist reconstruction with partial arthrodesis. A vascularized fibular graft was used. With 4 years of follow-up for patient 1 and 1 year for patient 2, range of movement in flexion was, respectively, 20°and 20°; in extension, 20 and 30°; in pronation, 80 and 30°; and in supination, 20 and 15°. Strength reached 68 and 57% of the strength of the opposite side. The time to union of the radial graft and the carpal graft was 2 months in both cases. This technique provided cosmetic and functional results matching the results reported in the literature. It increases the reliability of the procedure and the recovery process.
