Suture Fixation System Versus Tendonous Reconstruction in Thumb Carpometacarpal Arthroplasty: a Randomized Controlled Trial
Thumb carpometacarpal (CMC) arthritis affect 1 in 4 females and 1 in 12 males. Patients who
fail to respond to conservative treatment may benefit from surgery; however, controversy
exists over the most effective surgical technique. A popular technique, ligament
reconstruction with tendon interposition (LRTI) involves a trapeziectomy, followed by
reconstruction of the palmar oblique ligament using a harvested flexor tendon from the wrist.
We believe that use of a suture fixation system to reconstruct the palmar oblique ligament,
instead of harvesting a wrist tendon, may provide a superior repair. The objective of this
study is to compare functional outcome measurements among patients who receive CMC
arthroplasty using a suture fixation system (investigational group) to those who receive LRTI
surgery (control group). We hypothesize that patients in the investigational group will
demonstrate superior functionality, compared to patients in the control group.
