New operative technique for treatment of arthroscopically-confirmed injury to the scapholunate ligament by volar capsuloplasty augmented with a free tendon graft.
We report how scapholunate (SL) lesions found during arthroscopy were treated using a new palmar operation based on the use of a tendon loop formed using the palmaris longus tendon, with promising preliminary results. Scapholunate instability induced by hyperextension injury was diagnosed and graded arthroscopically. Volar capsuloplasty was then done by free tendon graft in the same session in 31 patients with grades II-IV scapholunate instability. Half of the patients operated on had a normal range of movement, and all except one had flexion-extension of at least 75% of the normal. Half of the patients had no pain or limitations of the use of the wrist, and although half the patients had some pain on exertion, not one had severe pain. These results are comparable to, or even better than, those reported using other methods of repair. The combined procedure saves money, diminishes the total recuperation time and, as autologous tissues are used for the repair, secondary operations for removal of the implant are unnecessary. This method seems to be a useful adjunct to the types of operative treatment available, although it is apparently not suitable in static grade IV SL instability.
