Lumbrical Plus after flexor tendon laceration

Charles Metzger, M.D. has a very nice example of a lumbrical plus index finger which occurred after laceration of both flexor tendons, with retention of the lumbrical tendon. This is a great example of paradoxical extension - when the patient tries to flex the index finger, the lacerated proximal flexor digitorum profundus pulls on the intact lumbrical muscle, which then tensions the lumbrical tendon, and extends the PIP joint.

Division or resection of the lumbrical tendon can make a notable difference in many cases
