## Overview Semitendinosus strain occurs from explosive hip extension during racing or jumping. It produces acute hind-limb lameness, swelling and heat over the caudal thigh, a shortened stride, and reluctance to fully extend the hip. Palpation of the hamstring region is painful. ## Causes Sudden maximal contraction during acceleration or takeoff. ## Diagnosis Clinical examination and ultrasound. ## Treatment Rest, anti-inflammatories, and gradual return to work. ## Recovery and Prognosis Good for most strains. Fibrotic myopathy can be a sequela. ## Prevention Adequate conditioning for the level of work.
