Abstract
We modified our original surgical technique of scapholunate intercarpal ligamentoplasty for treating chronic scapholunate dissociation. The aim of this study was to compare the outcomes in patients treated by the same surgical team with the original method and the modified method over two different time periods. Nineteen patients with a mean age of 40 years were treated with the original method (mean follow-up of 34 months, range 12–54), and 21 patients with a mean age of 38 years were treated with the modified method (mean follow-up of 27 months, range 13–40). In both groups, we found a significant improvement in pain levels, grip strength, functional scores in terms of QuickDASH and Patient-Rated Wrist Evaluation, and radiographic scapholunate gap and scapholunate angle after surgery. There were no significant differences between the two groups in outcome measures except the scapholunate gap, which was significantly better controlled by the modified procedure. Between the immediate postoperative period and the last follow-up, there was a significant increase in the scapholunate gap and scapholunate angle after the original method, while there only a small increase after the modified method. We conclude that both versions of the scapholunate intercarpal ligamentoplasty yield satisfactory clinical and radiological results in the short to mid-term. The modified method makes the triquetral surgical step easier and seems to better optimize the tension across the ligamentoplasty, thus maintaining the intercarpal correction.
