Proximal Interphalangeal Joint Arthroplasty Using a Graft From the Capitate

The Second Hospital of Qinhuangdao18 enrolled

Overview

The capitate had a widened distal base. The distal articulation can be used for proximal interphalangeal (PIP) articula reconstruction.

Previous anatomical studies have shown that the capitate had a widened distal base. The distal articulation was mainly with the base of the third metacarpal and partially with the base of the second metacarpal. The articulation was slightly flattened with a convex and concave dorsal articular surface. The contour stimulates our imagination and creativity to use a portion of the articular surface for PIP arthroplasty.
