title: Use of sonography in assessing elbow medial collateral ligament injury after arm wrestling.
abstract: Medial collateral ligament injury is an infrequent occurrence in arm wrestlers. We report here a male patient who injured his left elbow while arm wrestling. Ultrasonography showed a medial collateral ligament tear. We assessed both elbows using ultrasonography at his 3-year follow-up visit. Dynamic ultrasonography showed a decreased gap at the ulnotrochlear joint space in his left elbow. A medial collateral ligament tear in his right elbow was also evident using ultrasonography. This case report shows the advantages of ultrasonography, especially dynamic ultrasonography, in the evaluation of elbow injury. Ultrasonography provides more information than valgus stress radiography, arthrography, and magnetic resonance imaging in the assessment of medial collateral ligament injury. In addition, the contralateral side can readily be assessed for comparison during ultrasonography.
