title: Arthroscopic ligamentoplasty (bone-tendon-tenodesis). A new surgical technique for scapholunate instability: preliminary cadaver study.
abstract: We present an anatomical study and description of a new surgical technique for arthroscopic treatment of scapholunate ligament injuries. Five cadaver specimens were used to perform the technique. After arthroscopic surgery, anatomic dissection was performed to measure the distances to critical wrist structures such as the posterior interosseous nerve and the radial artery, and the size and position of the plasty. This arthroscopic technique offers three advantages: soft tissue damage is reduced (avoiding an extensive approach and injury to the secondary stabilizers and reducing scar tissue); injury to the posterior interosseous nerve is avoided (maintaining wrist proprioception and the role of the dynamic stabilizers); and a biotenodesis is made that ensures proper placement, tension and functionality of the flexor carpi radialis ligament reconstruction.
