## Overview Curb is soft-tissue swelling on the plantar distal aspect of the hock. Historically it referred to enlargement of the long plantar ligament, but similar swelling can arise from superficial or deep digital flexor tendinitis, periligamentous inflammation, or a combination. It is seen most often in racehorses, particularly Standardbreds, and may or may not cause lameness. ## Causes Conformational faults (sickle or curby hocks), trauma, or overload during training. ## Diagnosis Visible and palpable thickening distal to the point of the hock. Ultrasound identifies the specific structures involved. ## Treatment Rest, anti-inflammatory medication, and controlled exercise. Corrective shoeing addresses conformational contributors. Most cases resolve without long-term effects. ## Recovery and Prognosis Good. Recovery typically takes weeks to a few months. ## Prevention Attention to conformation and gradual conditioning.
