This study investigates the results of a technique using an extensor carpi radialis longus (ECRL) tenodesis for symptomatic scapholunate instability. Symptomatic scapholunate instability has been corrected so far either by limited wrist fusion or by various techniques of soft tissue repair. Limited wrist fusion greatly reduces wrist motion and increases the probability of osteoarthritis in the remaining mobile wrist segments. On the other hand, most types of soft tissue repair are technically difficult to perform and have disappointing results due to the inherent laxity. The presented dynamic approach was used in 20 wrists of 19 patients with static scapholunate instability. Preoperative evaluation included in all patients clinical examination, radiologic evaluation, and arthroscopy for establishing the diagnosis of static scapholunate instability. The technique involves the fixation of the ECRL tendon on the dorsal aspect of the scaphoid by means of a cancellous screw and a special washer. Dynamic ECRL tenodesis of the scaphoid is a safe and simple procedure that enhances the extension forces on the scaphoid in all wrist positions. The results of this preliminary report in 20 wrists showed dynamic ECRL tenodesis to be an effective treatment option for treating symptomatic static scapholunate instability.
