Abstract
|
|
|
|
Snapping triceps syndrome is a rare disorder in which the medial head of the triceps muscle moves anteriorly over the medial epicondyle during elbow flexion. Characteristically, visible and palpable snapping can be observed during elbow flexion. Several hypotheses have been proposed about its cause, but the etiology is still unclear. The diagnosis of snapping triceps syndrome is based on clinical symptoms and imaging studies. Early diagnosis is important to prevent symptom worsening and unnecessary surgical treatment. Snapping triceps syndrome is often accompanied by ulnar neuropathy. However, few electrodiagnostic findings have been reported for snapping triceps syndrome. Therefore, we report the ultrasonographic and electrodiagnostic findings in a patient with snapping triceps syndrome.
