骨样骨瘤的远端指骨是非常罕见的。我们描述一个病例骨样骨瘤远端指骨的无名指杵状手指畸形，改善后肿瘤切除。一名50岁的左撇子男子提出了一个历史的右手无名指疼痛没有任何创伤。无名指远端指骨有压痛、发红和杵状指畸形。X线平片显示病变中心有一圆形放射性显影区。计算机断层扫描和钆增强磁共振成像表明存在病灶。通过经舌入路切除病变。组织学检查证实存在骨样骨瘤。手术后他的疼痛立即减轻了。在2年随访时，他没有疼痛，杵状指畸形得到改善。如果杵状指畸形仅累及一个手指，应考虑慢性骨髓炎或骨样骨瘤的可能性。
Osteoid osteoma of the distal phalanx is very rare. We describe a case of osteoid osteoma of the distal phalanx of the ring finger with clubbed finger deformity that improved after tumour removal. A 50-year-old left-handed man presented with a history of right ring finger pain without any trauma. The distal phalanx of the ring finger had tender, redness, and a clubbed finger deformity. Plain radiography indicated a circular radiolucent area in the centre of the lesion. Computed tomography and gadolinium enhanced magnetic resonance imaging indicated presence of a nidus. The lesion was removed via the transungual approach. Histopathological examination confirmed the presence of an osteoid osteoma. His pain was immediately relieved after surgery. At the 2-year followup, he had no pain and the clubbed finger deformity had improved. In cases where clubbed finger deformity involves only one finger, the possibility of chronic osteomyelitis or osteoid osteoma should be considered.
