Purpose: Snapping triceps syndrome is dynamic condition in which medial head of triceps snaps (dislocates) over the medial epicondyle as the elbow is flexed. Materials and Methods: The symptoms are pain or snapping at the medial aspect of the elbow and/or symptoms from coexisting ulnar nerve irritation. The diagnosis can be made by dynamic ultrasonography. Results and Conclusion: And successful outcome can be archived by operative treatment, which are ulnar nerve anterior transposition and tenotomy of medial head of triceps.

Snapping triceps syndrome is a rare disease in which medial head of triceps dislocates over the medial epicondyle during elbow flexion. It is difficult to diagnose the snapping triceps syndrome, because that this syndrome is frequently misdiagnosed as other elbow disease such as ulnarnerve dislocation. The dynamic ultrasonographic imaging allows continual visualization of the ulnar nerve and triceps muscle throughout active elbow flexion and extension. We report two patients of snapping triceps syndrome who were diagnosed with the use of dynamic ultrasonography and treated with ulnar nerve anterior transposition and repositioning or resectioning of medial head of triceps.
