Sagittal band rupture leads to subluxation of the EDC tendon at the MCP joint. The common presentation involves pain and swelling at the MCP joint, visualization of extensor tendon subluxation during flexion, and inability to actively extend the MCP joint from a flexed position.

The treatment for chronic rupture, as in this case, involves surgical repair followed by six weeks in a relative motion splint, in which the injured MCP joint is placed in greater extension relative to adjacent joints. The video here demonstrates direct repair of a chronic degenerative sagittal band rupture of the right ring finger.
