The repetitive overhead use of the arm required by many sports may lead to impingement in the vulnerable avascular region of the supraspinatus and biceps tendons. The impingement syndrome may spill over at any time to involve the adjacent biceps tendon, subacromial bursa, and acromioclavicular joint and, as a continuum, with the passage of time, may eventuate in degeneration and partial, even complete thickness, rotator cuff tears later in life. Physical findings, particularly a positive impingement sign, confirm the diagnosis. In the young competing athlete, therapeutic measures consist of careful warm-up exercises, occasional rest by avoidance of the offending movement, and local modalities of ice, ultrasound, and transcutaneous stimulation along with anti-inflammatory medications. Surgical decompression achieved by resecting the coracoacromial ligament or a more definitive anterior acromioplasty may rarely be indicated.
许多运动中反复过度使用手臂，可能会导致在冈上肌和肱二头肌肌腱的易损无血管区域发生撞击。撞击综合征可能随时蔓延至相邻的肱二头肌肌腱、肩峰下囊和肩锁关节，并且随着时间的推移，作为一个连续过程，可能在晚年最终导致退变以及部分甚至全层的肩袖撕裂。体格检查结果，尤其是阳性撞击征，可确诊该病。对于年轻的竞技运动员，治疗措施包括仔细的热身运动、偶尔通过避免引起不适的动作来休息，以及局部应用冰敷、超声和经皮刺激，同时使用抗炎药物。很少需要通过切除喙肩韧带或更确切的前路肩峰成形术来进行手术减压。
