Management of pronation deformity in metacarpophalangeal joint implant arthroplasty

The tendency for the index finger to pronate after implant arthroplasty of the metacarpophalangeal joint is often a problem for the surgeon and hand therapist. The three splinting methods described correct this problem and yet allow the patient to participate in the full postoperative protocol during the early encapsulation phase. The method of choice, microfoam tape, moleskin, or Velcro, depends on the patient's ability to manage the material.
