Treatment with rest is usually needed for six to 12 weeks for Little Leaguer's shoulder. The athlete can be active so long as there are no symptoms. In some cases physical therapy is needed to regain range of motion and strength to prevent reinjury.

Surgery may be needed if pain persists or the athlete can't get back to his or her previous level of play. X-rays, MRIs, and CT scans are used to find fractures in anyone with continued pain. In such cases an operation may be needed.

Sometimes a fracture doesn't heal or the fracture site fills in with fibrous tissue instead of bone. It may be necessary to surgically hold the bone together with a plate, pin, or screw.
