In Little League shoulder, the growth plate involved is which of the following?

In Little League shoulder, the growth plate involved is which of the following?

• A. Distal humeral physis
• B. Proximal humeral physis
• C. Distal radius physis
• D. Distal femoral physis

Answer: (B)

Little League shoulder is an overuse injury of the proximal humeral growth plate. In skeletally immature athletes who throw, the physis near the shoulder—the proximal humeral physis—is the site subjected to repetitive stress, leading to pain, reduced motion, and sometimes physeal widening on imaging. The other growth plates listed (distal humerus at the elbow, distal radius at the wrist, distal femur at the knee) aren’t involved in this shoulder-specific condition.
