Blatt's capsulodesis for chronic scapholunate dissociation

We have reviewed prospectively 44 cases of chronic scapholunate dissociatio n treated by Blatt's dorsal capsulodesis, The diagnosis was based on clinic al and arthroscopic criteria. The minimum follow-up was 2 Sears. The result s were analysed clinically and radiologically, Postoperatively statisticall y significant reductions in wrist movements and grip strengths were noted. Delay in surgery and presence of compensation claims were also statisticall y significant factors. Patients with a high column/row index had higher ove rall good and excellent results. The scapholunate gap, scapholunate angle, carpal height and the type of instability as diagnosed on arthroscopy and c ineradiography did not affect the outcome significantly, The scapholunate g ap, scapholunate angle and the carpal height did not change significantly a fter operation.
