## Overview Tendinitis of the extensor carpi radialis occurs at or near its insertion on the metacarpal tuberosity. It is an overuse injury seen in sport horses performing intense collected work and produces swelling and pain on the dorsal proximal cannon. ## Causes Repetitive strain from collection or sudden overload. ## Diagnosis Palpation of pain and swelling, ultrasound of the tendon insertion, and response to diagnostic analgesia. ## Treatment Rest, anti-inflammatories, controlled rehabilitation, and correction of contributing training factors. ## Recovery and Prognosis Good with adequate rest. Return to full collection is gradual. ## Prevention Progressive conditioning and attention to workload.
swelling on the dorsal proximal cannon; pain on palpation; subtle lameness worse in collected work
