Mid-term outcomes of three commonly used surgical reconstructions for scapholunate instability.

This retrospective analysis reports the mid-term (>2 years) outcomes of capsulodesis, (modified) Brunelli tenodesis and bone-ligament-bone reconstruction for scapholunate ligament instability. In total, 60 patients (64 wrists) returned the Patient-Rated Wrist Evaluation and Disabilities of the Arm, Shoulder, and Hand questionnaires. Of these participants, 42 (46 wrists) returned for a wrist examination and radiographs. In the questionnaire group, the mean follow-up for capsulodesis was 11.8 years, tenodesis 5.9 years and bone-ligament-bone 8.9 years. In the objective outcomes group, the mean follow-up was 10.2 years for capsulodesis, 5.7 for tenodesis and 8.9 for bone-ligament-bone. In all groups, some patients showed radiographic deterioration, which did not always correlate with poor functional outcome. With a mean follow-up greater than 5 years, there was no substantial difference in clinical outcomes and patient-based outcome questionnaires between capsulodesis, tenodesis or bone-ligament-bone reconstruction for the treatment of scapholunate instability. This study emphasizes the need for further research. Surgeons should use the technique that produces the fewest complications. Level of evidence III.
