Thumb Metacarpophalangeal Joint

Five cases of chronic instability of the radial collateral ligament of the thumb metacarpophalangeal joint are presented. All patients were treated using the Mitek suture anchor to reattach the avulsed ligament to bone in its anatomical position. Tendon advancement or graft reinforcement was not used in conjunction with the repair. A stable thumb metacarpophalangeal joint was achieved in each case with no recurrent instability or pain found within 9 months of follow-up. Postoperatively, each patient exhibited a full return to activities of daily living within 2 to 3.5 months. Grip and pinch strength and range of motion were nearly the same as in the uninjured hand. We recommend the Mitek suture anchor as a simple and effective method of repairing the chronic radial collateral ligament injury. The importance of correct anatomical placement of the anchor is stressed, and guidelines for this are discussed.

Thumb Metacarpophalangeal Joint

Background Reconstruction of the radial collateral ligament (RCL) of the thumb metacarpophalangeal (MP) joint is commonly performed for chronic injuries. This study aims to evaluate the anatomical feasibility and reliability of using the abductor pollicis brevis (APB) tendon to reconstruct the RCL. Methods Ten cadaver arms were dissected to evaluate the relationship between insertions of the RCL and APB. A slip of the APB was divided from tendon and reflected proximally. The dissected tendon was deemed sufficient for reconstruction if it could be reflected to the footprint of the RCL origin. The size of the dissected APB slip was then compared with that of the RCL. Results The dissected slip of the APB could be fully reflected proximally to the RCL origin in all specimens. The APB insertion was also found to be closely approximated to the RCL insertion, averaging 2.1 mm distal and 1.8 mm dorsal. Significant differences existed between the lengths ( P < .001) of the APB slip and RCL, with no significant difference in widths ( P = .051). Conclusions A sufficient APB tendon slip can be obtained to reliably reconstruct the RCL of the thumb MP. The location of the APB insertion closely approximates the RCL insertion.
