Complete rupture of the long head of the biceps tendon and the distal biceps tendon

Abstract

The most common injury to the biceps muscle is rupture of the long head of the biceps tendon. A tear can occur proximally, distally or at the musculotendinous junction. Two cases are discussed, in both of which the patients felt a sudden sharp pain in the upper arm, at the shoulder and elbow respectively, and presented with a biceps muscle bump (Popeye deformity).
