PURPOSE: Rupture of the distal triceps tendon is an uncommon injury that may be unrecognized on clinical examination. The purpose of the study is to describe the role of US in @entity924 . MATERIALS AND METHODS: IRB approval was obtained and @entity1 gave written informed consent. Of 77 consecutive US examinations of the elbow obtained over a five-year period, eight @entity1 with correlative MR and surgery available were identified having @entity924 tear. RESULTS: N = 4 complete tears of the triceps tendon and n = 4 partial tears of the distal triceps involving the lateral/superficial head were identified. @entity1 with partial tear had a history of a single traumatic event that determined a sudden eccentric contraction of the triceps muscle against resistance. US demonstrated on axial and longitudinal planes a @entity924 that resulted in a fusiform swelling and retraction of the lateral/superficial head in four @entity1 . It was possible to identify the normal insertion of the medial head of the triceps moving the transducer medially. MR and surgical findings were concordant with US findings in every @entity1 . CONCLUSION: Ultrasound is able to differentiate complete from @entity924 . US has the potential to identify isolated lesions of the lateral/superficial head of the triceps with an intact medial head.
