Surgical arthroplasty of thumb carpometacarpal (CMC) joint osteoarthritis is commonly performed. Postoperative therapeutic protocols aim to improve range of motion and function of the revised thumb. We describe a case in which the thumb CMC joint had been chronically dislocated before surgery, with shortening of the soft-tissue dynamic and static stabilizers of the joint. The postoperative protocol addressed the soft tissues using splinting and exercises aimed at lengthening and strengthening these structures, with good results. It may be beneficial to evaluate soft-tissue tension and the pattern of thumb use after surgery for thumb CMC joint osteoarthritis to improve postoperative functional results.
Soft-tissue imbalance may exist around the thumbs of patients with CMC joint OA as a result of the etiology and chronicity of the condition.
It is advantageous to evaluate soft-tissue quality and patterns of thumb use before and after surgery for thumb CMC joint OA
A therapeutic protocol that addresses the soft tissues surrounding the joint may improve the ultimate outcome.
