Checkrein resection for flexion contracture of the middle joint

Pdf Summary

Checkrein resection is a surgical procedure used to correct flexion contracture in the middle joint of the fingers. The primary cause of this contracture is the checkrein ligaments, which become thick and fibrotic, restricting the full range of motion of the joint. This study has found that releasing the checkreins is sufficient to correct the contracture in cases where there is no osseous joint deformity. The checkreins are thicker and more diffuse than the bands described in previous literature, so the term "checkrein" is used in this study to differentiate them. The procedure involves making a mid-lateral incision and isolating the checkreins, which extend from the volar plate to the proximal phalanx. The checkreins are then excised, while preserving the continuity of the volar plate and the ladder vessel, which provides vascular supply to the flexor tendons. Intraoperative extension was achieved in the majority of cases, and postoperative management involves the use of splints to maintain extension achieved during surgery. The study concludes that checkrein resection should be the primary objective in the treatment of middle joint flexion contracture, and careful postoperative management is important in maintaining extension.
