Thrower’s Fracture of the Humerus: An Investigation of Risk Factors Following an Unlikely Scenario
A 26-year-old amateur baseball player without prodromal arm pain sustained a thrower’s fracture of the humerus on a warm-up throw performed with submaximal effort. The fracture occurred during the first throwing session following a 6-week layoff. The patient was treated nonoperatively and made a full recovery, but he elected to not return to throwing sports.Conclusion:
Because of the lack of risk factors in this case, we suggest that time off or irregularity in throwing may play a greater role in a thrower’s fracture than previously established. Recreational throwers should undergo appropriate preseason training before returning to throwing.
