Stress fractures: diagnosis and management in the primary care setting.

Stress fracture represents an overuse injury of the bone resulting from excessive repetitive stress. Diagnosis in most cases is based on clinical evaluation. Plain radiographs may show characteristic changes 2 to 4 weeks from onset of symptoms. Increasingly, magnetic resonance imaging is recognized as the study of choice in the evaluation of stress injury of the bone.
