The overhead throwing motion subjects the elbow to a predictable pattern of forces, including medial tension, lateral compression, and posterior shear, that in turn result in a predictable pattern of injuries. Careful history taking, thorough physical examination, and judicious diagnostic imaging allow clinicians to correctly diagnose ulnar collateral ligament (UCL) injury. Athletes with UCL injury complain of acute or chronic medial elbow injury, resulting in decreased throwing effectiveness, with loss of control and/or velocity. Magnetic resonance imaging is the gold standard for diagnosis, but stress ultrasound rapidly is becoming an important adjunct, particularly in diagnostically challenging situations.
overhead 投掷动作使肘部承受可预测的力模式，包括内侧张力、外侧压缩和后侧剪切，这反过来又导致可预测的损伤模式。仔细的病史采集、彻底的体格检查和明智的诊断成像使临床医生能够正确诊断尺侧副韧带 (UCL) 损伤。UCL 损伤的运动员抱怨急性或慢性肘内侧损伤，导致投掷效果降低，失去控制和/或速度。磁共振成像 (MRI) 是诊断的金标准，但应力超声技术迅速成为一种重要的辅助手段，特别是在诊断具有挑战性的情况下。
