DORSAL CAPSULODESIS USING SUTURE ANCHORS

Scapholunate instability can be treated by stabilizing the scaphoid with the dorsal wrist capsule, which acts as a tether to control palmar rotation. We began using suture anchors instead of pull-out wires to secure the dorsal capsule to the scaphoid. Thirty-eight patients were treated with this method, and 35 were followed an average of 24 months. Sixteen were pain free, 12 had pain with activity, and 7 required additional surgical treatment. Patients regained 85% of expected grip strength, with 25 of the 35 returning to their preinjury job. The scapholunate gap, reduced at the time of surgery, recurred in 31 of the 35 patients, but this alone did not correlate with symptoms. This procedure improves symptoms in a majority of patients, but like other procedures described for scapholunate instability, it does not completely cure the problem.
