In brief
The common “jammed finger” occurs at the proximal interphalangeal (PIP) joint and is too often minimized by the coach and player and inadequately treated by the physician. Unless appropriately diagnosed and treated, volar plate injuries at that joint may result in permanent limitation of motion. The volar plate can be injured when the athlete misses a Frisbee throw or a basketball pass, because these activities force hyperextension of the PIP joint and tear the volar plate away from its insertion. The authors discuss the functional anatomy of the PIP joint, the mechanism of injury, treatment, possible complications, and rehabilitation.
