title: Outcome of arthroscopic reduction association of the scapholunate joint.
abstract: This study evaluates the arthroscopic reduction association scapholunate technique and outcomes. A total of 18 patients with chronic scapholunate instability with mean follow-up of 36 months were reviewed. Postoperatively, the mean visual analogue score was 2.5 and the mean DASH score was 8. The grip strength was 27 kg on the operative side compared with 32 kg on the uninjured side. The mean wrist flexion was 46° and extension was 56°. Seven patients had complications. Six patients had scapholunate joint widening, one had windshield-wipering of the screws with loss of reduction, and two demonstrated progression of scapholunate advanced collapse deformity. Four patients underwent revision surgeries: two revision arthroscopic reduction association scapholunates and two proximal row carpectomies. A preoperative scapholunate gap of greater than 5 mm and the presence of scapholunate advanced collapse Grade I were both predictive of a complication or revision surgery. Patients with a scapholunate gap of greater than 5 mm or scapholunate advanced collapse had statistically higher complications rates.Level of Evidence IV.
