Bone scan utilization in the differential diagnosis of exercise-induced lower extremity pain

Abstract

In 4 patients with lower extremity pain and either negative or equivocal radiograhic findings, the bone scan was definitely positive for stress fracture in all, accurately localized the lesion, and permitted proper therapy. The condition in all instances proved to be a microfracture at the origin or insertion of a muscle. The pain was always intensified by physical activity.
