title: Interference screw failure in distal biceps endobutton repair: case report.
abstract: Endobutton (Arthrex, Naples, FL) fixation of distal biceps rupture with interference screw fixation provides for a secure repair, allowing for early motion. We present a case in which Endobutton fixation failed with a loose interference screw, rendering the distal biceps attachment incompetent. Revision surgery with an extensile approach, mobilization of the biceps, and repeat Endobutton fixation at a more distal site provided a secure fixation with an excellent clinical outcome. An understanding of the mechanism of failure might allow surgeons to perform this procedure with a lower incidence of complications.
