Internal impingement is a multifactorial condition of the shoulder in which there is repetitive or excessive contact of the greater tuberosity against the posterosuperior glenoid with the arm in abduction and external rotation. This abnormal contact can lead to labral and partial rotator cuff tears. This condition is generally seen in overhead athletes such as baseball and tennis players. Over the past decade, our understanding of this condition has improved with an emphasis on nonsurgical care including physical therapy focusing on posterior shoulder stretching. This has been found to be therapeutic as well as protective against further injury. Surgical care is reserved for those athletes who do not improve with conservative management. For the patient to have a good outcome, microinstability (capsular laxity or contracture) should also be addressed with any surgical intervention.
