The two cases presented demonstrate the management of aneurysmal bone cysts of the metacarpal, which destroyed the normal bone architecture. Treatment of both cases included wide resection and metacarpal reconstruction with an intercalary fibular allograft. Denosumab use contrasts these two cases and is helpful in reestablishment of a cortical rim for fixation in the absence of a 1-cm margin proximally or distally to preserve the native carpometacarpal and metacarpophalangeal joints. Surgical resection and allograft reconstruction is a viable treatment for expansile metacarpal aneurysmal bone cysts, and neoadjuvant denosumab has utility in creating an ossified margin for fixation.
所呈现的这两个病例展示了掌骨动脉瘤样骨囊肿的治疗方法，该囊肿破坏了正常的骨结构。这两个病例的治疗均包括广泛切除以及采用腓骨中段同种异体骨移植进行掌骨重建。地诺单抗的使用与这两个病例形成对比，并且有助于在近端或远端没有1厘米切缘的情况下重建皮质边缘以进行固定，从而保留原生的腕掌关节和掌指关节。手术切除和同种异体骨重建是治疗扩张性掌骨动脉瘤样骨囊肿的一种可行方法，新辅助地诺单抗在为固定创造骨化边缘方面具有实用价值。
