	Abstract

We treated a prospective series of 18 patients (nine men and nine women) with a mean age of 35 years (range 15 to 57), with chronic predynamic or dynamic scapholunate instability by a dorsal intercarpal ligament capsulodesis using the modified Mayo technique. All the patients were assessed by the modified Mayo wrist score and DASH questionnaire. Wrist arthroscopy was done in all patients before open surgery in order to grade the scapholunate instability and correlate the findings with the radiographic and MRI results. At an average follow-up of 45 months (range 34 to 60) pain significantly diminished (P < 0.05) with improvement in the grip strength (P < 0.005) in all 18 cases. Wrist motion remained almost the same. The mean Mayo wrist score improved from 62 to 84 (P < 0.005).We recommend dorsal capsulodesis by using the dorsal intercarpal ligament flap for the treatment of scapholunate dissociation, when the ligament is still repairable.
