Reconstruction of the radial head can be complicated in cases of wide resection, particularly in those cases including the proximal radial shaft. In such cases, radial head replacement may not be possible because of lack of adequate bone stock. Here, we report the use of a radial head prosthesis incorporated with a vascularized fibula for immediate anatomic restoration of the forearm and elbow. We present a case of a pathologic fracture non-union in the proximal radius in a 57-year-old female with a history of multiple myeloma. Non-operative management of the fracture was unsuccessful after chemotherapy and radiation. The proximal radius and radial head were resected and reconstructed with vascularized fibula graft in conjunction with immediate radial head prosthesis. The osteotomy site healed at 6-weeks and follow-up at 1 year showed good functional outcome. We feel that the use of this construct has definite promise and may be considered for reconstruction following resection of the proximal radius.
在广泛切除的情况下,桡骨头重建可能会很复杂,尤其是那些包括桡骨近端骨干的病例。在这种情况下,由于缺乏足够的骨量,可能无法进行桡骨头置换。在此,我们报告使用一种结合带血管腓骨的桡骨头假体,以立即对前臂和肘部进行解剖学重建。我们展示了一例57岁患有多发性骨髓瘤病史的女性桡骨近端病理性骨折不愈合病例。化疗和放疗后,骨折的非手术治疗未成功。切除桡骨近端和桡骨头,并用带血管腓骨移植结合即时桡骨头假体进行重建。截骨部位在6周时愈合,1年的随访显示功能结果良好。我们认为使用这种结构有明确的前景,在切除桡骨近端后可考虑用于重建。
