Variations in the Minimum Joint Distance During Flexion and Abduction of the Thumb Carpometacarpal Joint: Potential Implications for Joint Degeneration
Flexion and abduction of the thumb may contribute to degeneration of the volar side of the metacarpal articular surface. In particular, during maximum flexion, narrowing on the volar side of the trapezium was observed, indicating that flexion may contribute to degeneration not only in the central region but also on the volar side of the trapezium.
