Avulsion of the distal triceps tendon with fracture of the radial head

Abstract

We present a rare case of associated distal triceps tendon avulsion with radial head fracture; the lateral and medial collateral ligaments of the elbow were also ruptured. The patient underwent surgical procedure for the reinsertion of the triceps tendon using metallic anchors, radial head prosthetic replacement, and repair of the lateral collateral ligament. We believe this combined injury pattern of radial head fracture with triceps tendon rupture or avulsion should be considered according to the concept of the spectrum of elbow instability.
