(a) Isolated rupture of the anterior medial ulnar collateral ligament (aMUCL) by valgus stress trauma. The patient was typically suffering from a limited range of motion in flexion. Full range of motion with a stable elbow was restored with conservative treatment 10 weeks after trauma. (b) MRI proofed isolated aMUCL rupture of the photographed patient. The sagittal plane illustrated an inflammatory reaction. (c) The frontal plane demonstrated the rupture of the MUCL complex from its proximal insertion on the medial epicondyle humeri.
