Kinematics of partial and total ruptures of the medial collateral ligament of the elbow (original) (raw)

This study investigates the kinematics of partial and total ruptures of the medial collateral ligament (MCL) of the elbow. Using an osteoligamentous intact elbow preparation, 3D measurements were performed to assess angular displacement, medial joint opening, and radial head translation under relevant stress. Results indicate that significant joint opening and instability occur primarily after complete transection of the anterior bundle of the MCL, with implications for diagnosing and evaluating elbow instability.
