title: Poor results of radio-scaphoid capsulodesis for scapholunate dissociation.
abstract: We reviewed 17 patients 64 (range 29-123) months after dorsal radioscaphoid capsulodesis for scapholunate dissociation. Mean loss of key pinch was 13%, grip strength 18%, wrist flexion 22% (p < 0.001), and total wrist ROM 17% (p < 0.005). VAS (0 = best; 100 = worst) was 30(±28) for pain, 43(±30) for function, and 33(±33) for general satisfaction with the outcome. Mean Quick-DASH and PRWE scores were 27 and 34, respectively. The mean scapholunate gap was 3.5 mm before surgery, 1.9 mm after surgery, and 3.3 mm at review. The corresponding scapholunate angles were 63°, 46°, and 70°, respectively. The mean radioscaphoid angle with the wrist maximally flexed was 84° (69-99) for the patients and was 91° (77-103) in ten wrists of volunteers. Six patients had changed their jobs because of the wrist. Three patients stated that they would not have consented to operation if they had known the outcome in advance. Radioscaphoid capsulodesis does not prevent volar flexion of the scaphoid.
