title: Combined Tenodesis-Capsulodesis for Scapholunate Instability: Minimum 2-Year Follow-Up.
abstract: BackgroundThe aim of this study is to evaluate the clinical and radiological midterm results of a combined dorsal tenodesis-capsulodesis for static and reducible scapholunate dissociation (SLD).Patients and MethodsWe evaluated 20 of 22 consecutive patients with static SLD minimum with follow-up of 2 years operated between 2003 and 2012. The mean age was 40 years (range: 23-65 years). Seventeen were men. Final evaluation included comparative wrist range of motion (ROM) and grip strength, pre- and postoperative pain and function by visual analog scale, and QuickDASH and Wrightington scores. Radiographs included preoperative, early postoperative, and final X-rays. Scapholunate space (SLS) and scapholunate and radioscaphoid angles (SLA and RSA) were measured. Statistical significance was evaluated with Studentt-test, considered significant whenp< 0.05.ResultsMean follow-up was 67 months (range: 24-126 months). Mean final ROM was: flexion 55 degrees (73%), extension 62 degrees (90%), radial deviation 19 degrees (82%), and ulnar deviation 44 degrees (90%). Mean grip strength was 44 kg (92%). Pain at rest improved from 3.4 to 0.5 (p< 0.05). Pain in activity improved from 7 to 1.7 (p< 0.05). Final function was 8.5 (preoperative, 5.2;p< 0.05). Mean QuickDASH score improved from 38 to 8 (p< 0.05). Functional Wrightington score was as follows: 13 excellent, 3 good, 1 regular, and 3 poor. There were three postoperative minor complications. Radiological results (preoperative/early postoperative/final follow-up) were as follows: SLS, 4.7/1.6/1.8 mm; and SLA, 60/50/62 degrees; RSA, 39/45/37 degrees. Four patients showed arthritic changes (two SLAC wrist).ConclusionThe clinical and radiological results with more than 2-year follow-up suggest that this technique may be effective, reproducible, and safe for symptomatic static and reducible SLD.Level of EvidenceLevel IV, case series.
