Randomized Controlled Trial Comparative Study Clinical TrialLigament reconstruction with or without tendon interposition to treat primary thumb carpometacarpal osteoarthritis. A prospective randomized study.
Trapezial excision with ligament reconstruction and trapezial excision with ligament reconstruction combined with tendon interposition have proven to be highly effective techniques for treating primary osteoarthritis of the thumb carpometacarpal joint. To determine whether tendon interposition and proximal migration of the thumb metacarpal affect the objective and subjective outcomes, we compared the long-term outcomes of these two procedures performed in similar patient groups. ⋯ Tendon interposition does not affect the outcome after the ligament reconstruction for the treatment of osteoarthritis of the thumb carpometacarpal joint. Furthermore, proximal migration of the thumb metacarpal does not appear to influence the functional outcome.
