Evaluation of the Reduction and Association of the Scaphoid, Capitate, and Lunate Procedure: A Biomechanical Analysis.

ABSTRACT:

Background

This study evaluates whether augmentation of the reduction and association of the scaphoid and lunate (RASL) procedure with a temporary scaphocapitate (SC) screw will improve the stability of the carpus and scapholunate (SL) joint. Primary endpoint was SL joint diastasis with simulated clenched fist grip.

Methods

Twelve cadaveric wrists were subjected to repeated cycles at a range of physiologic transcarpal axial forces simulating clenched-fist loading. We measured SL joint motion in scapholunate interosseous ligament (SLIL)-intact wrists and after transecting the SLIL. Outcomes measured included static diastasis and cyclic motion diastasis, defined as the change in SL diastasis from zero newtons to peak force during clenched-fist loading. The RASL procedure was t
