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.
骨样骨瘤很少发生在踝关节水平。在这种肿瘤情况下，关节镜切除术是一种不常见的治疗方式。我们报告了一例年轻男性距骨颈骨样骨瘤的病例。通过 MRI 诊断。由于肿瘤位于关节内和骨膜下，因此采用关节镜切除。病理检查证实了骨样骨瘤的诊断。恢复顺利；手术后立即完全缓解疼痛，患者手术后几个月仍无症状。关节镜技术可使关节得到全面探查，并可彻底切除肿瘤。这种微创方法降低了感染和功能风险（关节僵硬）。在适用的情况下，应提倡采用侵袭性较小的切除技术，以获得手术标本的病理诊断。
