Review Question - QID 213060

A 13-year-old baseball pitcher presents with persistent pain of the right shoulder over the last 2 years. He denies any antecedent trauma or dislocations. They report sensations of instability when performing activities with external rotation and abduction. Physical examination reveals an internal rotation deficit of 10 degrees on the right shoulder. The patient is able to hyperextend the elbows and knees to 12 degrees, can place both palms on the floor with knees fully extended, and hyperextend the small finger MCP joint past 90 degrees. There is a positive anterior and posterior load and shift test with a positive sulcus sign. What is the likely diagnosis and next best step in management?
