In this medical malpractice case, the surgeon performed a trigger finger release on both the thumb and pinky finger. During the trigger thumb release, the flexor pollicis longus (FPL) tendon was partially cut and repaired. The FPL tendon later ruptured and was not repaired within a short enough time to perform a simpler primary repair.  A complex tendon transfer surgery was then performed using the FDS tendon from the ring finger to restore function to the thumb.
