We report a patient with osteoid osteoma that developed in the lunate.
The patient was a healthy 28-year-old male who had the right wrist joint pain and osteosclerosis of the lunate was noted on plain radiography. Kienböck's disease was considered at the first examination, but a nidus was observed on computed tomography, suggesting osteoid osteoma in the lunate. The resection of the bone lesion and bridging external fixation to prevent post-operative collapse of the lunate was performed. Histopathological diagnosis was also osteoid osteoma in the lunate. At 3 years after surgery, no recurrence of the lesion or progression of collapse of the lunate has occurred.
As the development of osteoid osteoma in the lunate is a markedly rare pathology and there are many differential diseases, the time to diagnosis may be prolonged. Moreover, it may be useful to attach bridging external fixation to prevent a collapse of the lunate.
我们报告一例发生于月骨的骨样骨瘤患者。
该患者为一名28岁健康男性，有右腕关节疼痛，X线平片显示月骨骨质硬化。初次检查时考虑为Kienböck病，但计算机断层扫描发现一个瘤巢，提示月骨骨样骨瘤。遂行骨病变切除术及桥式外固定以防止术后月骨塌陷。组织病理学诊断也为月骨骨样骨瘤。术后3年，病变无复发，月骨也无塌陷进展。
由于月骨骨样骨瘤的发生是一种极为罕见的病理情况，且存在多种鉴别诊断疾病，诊断时间可能会延长。此外，附加桥式外固定以防止月骨塌陷可能是有用的。
