A Rare Complication after Arthroscopic Partial Trapeziectomy and Pinning: Rupture of the Flexor Digitorum Profundus of the Index Finger

Abstract

The thumb carpometacarpal (CMC) joint is the most common site for osteoarthritis of the wrist due to its unique biomechanical anatomy. Many motion-preserving surgical treatments have been proposed. Arthroscopic-assisted motionpreserving surgical technique is popular because it produces a small wound and results in a shorter recovery time than other procedures. Migration of implants, instability, dorsal displacement of the CMC joint, radial nerve neuritis and persistent pain are common complications of this kind of surgery, but tendon rupture is rare. We present the case of a 55-year-old male with flexor digitorum profundus rupture of the index finger after arthroscopic partial trapeziectomy and pinning for CMC joint arthritis.
