## Overview Tibial stress fractures are incomplete cracks from repetitive concussion, most common in racehorses. The caudal tibial cortex is typically affected. Lameness worsens with exercise. Localized pain, heat, or soft-tissue swelling may be present. Bone scan diagnoses them before they are visible on radiographs. Rest prevents propagation to a complete fracture. ## Causes Cyclical loading. ## Diagnosis Nuclear scintigraphy. Radiographs often normal early. ## Treatment Strict rest, usually 8 to 12 weeks or longer. ## Recovery and Prognosis Excellent if rested before complete fracture. ## Prevention Training modifications when early lameness appears.
hind-limb lameness worse with exercise; localized pain on tibial palpation; possible heat and swelling; diagnosed on bone scan before radiographs
