Reconstruction of the ulnar collateral ligament of the thumb metacarpophalangeal joint: A cadaver study

The Duplicated Thumb: A Review

“…17 When the UCL at the MCP joint requires repair, Hogan et al found that interference knot fixation of the tendon graft yielded superior results among four methods of reconstruction, demonstrating further that surgical technique plays an important role in functional as well as aesthetic outcome. 36 In 1983, Tada et al reported the functional outcomes of 237 radial polydactyly cases. 4 The study found 76% good, 20% fair, and 4% poor results in patients undergoing initial surgical reconstruction with an average 3-year follow-up.…”

Biomechanical Comparison of Ulnar Collateral Ligament Reconstruction Techniques

“…10 With interference knot fixation, the free ends of the tendon are passed through a single bone tunnel at the origin of the ligament and tied into an irretrievable square knot. Biomechanically, this method of graft fixation outperformed standard techniques for reconstruction of the UCL of the thumb.…”

Morphometric analysis of metacarpophalangeal and proximal interphalangeal palmar plates

“…In chronic rupture of ulnar collateral ligament of MCP joint, many treatments have been described to restore the stability including local tissue, dynamic stabilization, and static ligament reconstruction using free tendon grafts with 50 to 90% success in regaining of joint stability (Hogan et al, 2005). A thorough knowledge of the PP morphometry would permit surgeons to create new surgical techniques, for example using the different shapes of PP grafts (e.g., a diagonal or a circular flap to harvest a longer graft) for these challenging injuries.…”
