Carpal Kinematics in the Normal, Scapholunate Ligament Deficient, and Surgically Reconstructed Wrist.

ABSTRACT: The objective of this study was to evaluate scaphoid, lunate and capitate kinematics after disruption to the primary and secondary scapholunate ligamentous stabilizers, and to assess the effectiveness of scapholunate ligament reconstruction in restoring carpal kinematics post-operatively. Seven upper extremities were harvested, and the scapholunate interosseous ligament (SLIL) was divided. Specimens were mounted onto a computer-controlled dynamic wrist simulator, and simulations of flexion-extension, radial-ulnar deviation, and dart-thrower's motion were undertaken by simulated force application to the wrist tendons. Three-dimensional kinematics of the scaphoid, lunate and capitate were measured using bi-plane X-ray fluoroscopy in the native and ligament deficient state. The SLIL was then
