Recurrent Dislocation of Hand

Keywords
arthroplasty, graft, capitate, artery
Brief summary
The capitate had a widened distal base. The distal articulation can be used for proximal interphalangeal (PIP) articula reconstruction.
Detailed description
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.

Inclusion criteria
1. an articular defect at the proximal aspect of the PIP joint; 2. the defect larger than 5 mm × 5 mm in size based on intraoperative findings.
Exclusion criteria
