Purpose

Although multiple surgical options exist for chronic static scapholunate dissociation, no single procedure has been found to be superior clinically or kinematically. We hypothesize that the reduction and association of the scaphoid and lunate (RASL procedure) is a safe and effective procedure that improves function and alleviates pain in the injured wrist. The purpose of this study is to report long-term follow-up of patients undergoing the RASL procedure over a 20-year period.

Method

Between December 1991 and September 2008, the senior author performed 36 RASL procedures for chronic static scapholunate dissociation. This reconstruction involves reduction of the rotational deformity and diastasis between the scaphoid and lunate through a dorsal approach to the wrist. Maintenance of reduction is accomplished with a cannulated, headless, smooth-shafted compression screw directed from the scaphoid to the lunate along the anatomic axis of rotation between the two bones. For the purposes of this study, patients were evaluated by visual analog pain scale (VAS), Disability of the Arm, Shoulder and Hand questionnaire (DASH), SF-36 health survey, physical examination and radiographs.
