In some cases, congenital or acquired posterior instabilities of the MP joint of the thumb may cause pain or create functional disorders. It is possible to stabilize the metacarpophalangeal joint by partial resection of the ligament joining the two sesamoids which makes it possible to move and suture them toward each other. An enlargement plasty of the pulley then is required. This technique prevents hyperextension but without restricting flexion or opposition. The digital nerves must be carefully identified and protected.
在某些情况下，拇指掌指关节先天性或后天性的后方不稳定可能会导致疼痛或引发功能障碍。通过部分切除连接两块籽骨的韧带，有可能稳定掌指关节，从而能够将它们相互移动并缝合。然后需要进行滑车扩大成形术。该技术可防止过度伸展，但不限制屈曲或对掌动作。必须仔细识别并保护指神经。
