Dorsoradial ligament imbrication is a direct and effective alternative to ligament reconstruction or metacarpal osteotomy in patients with symptomatic thumb carpometacarpal (CMC) joint instability. This procedure is performed by imbricating either the trapezial or the metacarpal attachment of the dorsoradial ligament with the use of a suture anchor. The procedure is indicated in the setting of chronic hyperlaxity or instability of the thumb CMC joint. Significant arthritic changes in the thumb CMC joint are a contraindication for this procedure. We present our technique along with an anatomic dissection to demonstrate the ligament and surgical procedure on an anatomic specimen. We also present results from 3 patients who underwent this technique with images and clinical results for 3 patients with long-term follow-up.
Level IV-Therapeutic.
对于有症状的拇指腕掌（CMC）关节不稳定患者，背桡侧韧带重叠术是韧带重建或掌骨截骨术的一种直接且有效的替代方法。该手术通过使用缝线锚钉对背桡侧韧带的大多角骨或掌骨附着点进行重叠来完成。该手术适用于拇指CMC关节慢性松弛或不稳定的情况。拇指CMC关节有明显的关节炎改变是该手术的禁忌症。我们展示我们的技术以及解剖学剖析，以在解剖标本上展示韧带和手术过程。我们还展示了3例接受该技术患者的结果，以及3例长期随访患者的图像和临床结果。
