Case DescriptionA 14-year-old right hand-dominant wide receiver presented to a walk-in sports medicine clinic for right anterior-lateral shoulder pain after he was tackled on his right shoulder the day before. The patient denied any radicular symptoms after the hit or the next day. He stated that his pain was dull and rated 7 out of 10 in severity. Initial evaluation revealed that he had full active range of motion (ROM) of his right shoulder but did have anterior pain with forward flexion of his shoulder. Strength testing of his rotator cuff was full and symmetric to the contralateral side. Impingement maneuvers were positive for pain, but cross-arm maneuver, speeds, and empty can test were negative. Radiographs of the right shoulder did not reveal any bony abnormalities. The patient was diagnosed with a contusion, provided with nonsteroidal anti-inflammatory medications as needed, and recommended 2 wk of rest from football before reevaluation. However, the patient canceled his followup appointment because his symptoms completely resolved and the patient returned to football without restriction.Three weeks after the initial injury, the patient was seen in the sports medicine clinic for right shoulder pain secondary to throwing a football at practice the day before. The patient stated he had immediate pain in his right shoulder. He plays wide receiver but throws recreationally at practice. Pain is located superior-laterally without any radicular symptoms. On examination, his shoulder did not have any deformity on observation with intact skin. Palpation indicated pain at the AC joint and lateral acromial edge. There was no pain with a proximal humeral head squeeze. Active ROM was limited due to pain. He could complete ROM in forward flexion to 90 degrees, abduction to 90 degrees, external rotation (ER) to 40 degrees, and internal rotation (IR) to the sacrum. Passive
