Distal radius fracture nonunion can result in significant deformity, loss of function, and chronic pain. Presented here is a case of distal radius nonunion that was surgically reconstructed with a pedicled distal ulna bone graft based on the periosteal branches of the posterior interosseus artery (PIA). This technique has limited prior utilization for adult distal radius nonunion treatment but offers an effective option for surgical reconstruction of distal radius nonunion with preservation of the radiocarpal joint, utilizing a less invasive surgery that also reduces hospitalization stay. The objective of this report is to provide the first illustrative step-by-step surgical technique for the vascularized distal ulnar bone graft technique and demonstrate its promising utility in clinical practice.
桡骨远端骨折不愈合可导致严重畸形、功能丧失和慢性疼痛。本文介绍了一例桡骨远端骨折不愈合病例，采用基于骨间后动脉（PIA）骨膜支的带蒂尺骨远端骨移植进行手术重建。该技术在成人桡骨远端骨折不愈合治疗中的应用此前有限，但为保留桡腕关节的桡骨远端骨折不愈合手术重建提供了一种有效选择，采用的手术侵入性较小，还缩短了住院时间。本报告的目的是提供血管化尺骨远端骨移植技术的首个详细分步手术技术说明，并证明其在临床实践中的良好效用。
