Diagnosis: The x-ray reveals a stress fracture of the fifth metatarsal (arrow).
Most diaphyseal (shaft) fifth metatarsal stress fractures are caused by chronic overloading in a young athlete (usually from jumping and pivoting activities). Treatment is dependent on time to diagnosis, age, and level of future physical activity desired. Initial management is a splint, non-weight bearing with orthopedic consultation.
