We present the case of a 22-year-old woman with an aneurysmal cyst of the right proximal radius, treated by resection and a free bone graft (microvascular fibular transfer), without recurrence after 4 years. Over a 4 month period, there was a rapidly expanding and lytic lesion found in the radius. There were symptoms of elbow and wrist pain and early radially innervated muscle weakness. Radiological examination showed a localized tumour of the proximal radius, type 2, grade C, according to the classification of Campanacci. Biopsy led to the diagnosis of an aneurysmal bone cyst. Complete tumour resection was followed by a free vascularized fibular bone graft, resulting in good functional improvement, without local recurrence. Aneurysmal bone cysts are a rare condition, and the location in the radius has not previously been described. Vascularized bone grafts are mechanically and biologically superior in this type of case.
我们报告一例22岁女性右桡骨近端动脉瘤样骨囊肿的病例，采用切除及游离骨移植（微血管腓骨转移）治疗，4年后无复发。在4个月的时间里，桡骨出现一个迅速扩大的溶骨性病变。有肘部和腕部疼痛症状以及早期桡神经支配的肌肉无力。根据坎帕纳奇分类，放射学检查显示为桡骨近端2型C级局限性肿瘤。活检诊断为动脉瘤样骨囊肿。肿瘤完整切除后进行游离带血管腓骨移植，功能得到良好改善，无局部复发。动脉瘤样骨囊肿是一种罕见疾病，此前尚未有桡骨部位的相关报道。在这类病例中，带血管骨移植在机械性能和生物学性能方面更具优势。
