Intramedullary, unicortical repair of distal biceps tendon rupture.

Historically-used bicortical repair of distal biceps tendon rupture are at risk for posterior interosseous nerve palsy. Here we present a technique, and associated case report, utilizing unicortical repair with a suture cortical button device for this injury. The described technique provides robust fixation and avoids the rare, but potentially devastating complication of posterior interosseous nerve palsy.
