Abstract

Eighteen patients with a proximal interphalangeal joint fracture-dislocation involving at least half of the palmar articular surface were treated with hemihamate arthroplasty, achieving a mean of 70° flexion at 14 months. This technique is an effective option for complex injuries.<b>Level of Evidence:</b> IV.
