Proximal Interphalangeal Joint Arthroplasty Using a Graft From the Capitate (PIPPC)
The capitate had a widened distal base. The distal articulation can be used for proximal interphalangeal (PIP) articula reconstruction.

- range of motion [ Time Frame: 37 to 46 months postoperatively ] [ Designated as safety issue: Yes ]Active range of motion of the hand were measured by a goniometer.
- grip strength [ Time Frame: 37 to 46 months postoperatively ] [ Designated as safety issue: Yes ]The grip strength of the thumb to the injured finger was measured using dynamometers
- pinch strength [ Time Frame: 37 to 46 months postoperatively ] [ Designated as safety issue: Yes ]The pinch strength of the thumb to the injured finger was measured using dynamometers

Experimental: Capitate bone grafting
18 patients with PIP joint defects were included in the study. There were 13 male and 5 female patients with a mean age of 31 years (range, 18-47 years). The injury occurred in the right hand in 11 patients and on the left hand in 7. The injured PIP joints were in the index finger (n=7), long finger (n=9), and ring finger (n=2).
Procedure: Capitate bone grafting
Capitate bone graft transfer for PIP joint 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.
