Evaluation of suspected stress fractures.

Abstract

Stress fractures can occur if normal bone is exposed to repeated abnormal stress (fatigue fractures) or if normal stress is placed on bones with compromised elastic resistance (insufficiency fractures). This article describes two patients without a history of excessive stressful activity or apparent metabolic bone disease who developed bilateral distal tibial stress fractures. Different etiologies, clinical presentation, differential diagnosis, and diagnostic imaging modalities of stress fractures are discussed.
