Capped Hock

Hygroma Of The Tuber Calcis

Capped hock is a swelling that occurs over the point of hock. It is typically considered to be an unsightly blemish rather than a cause of lameness in horses. Capped hocks are usually caused by self-induced trauma such as horses that repeatedly kick stalls or horse trailers, lying on hard floor with insufficient bedding or from injury.


Swelling on the point of the hock


  • History
  • Clinical signs
  • Physical exam
  • Ultrasonography


Identification and elimination of the causeEnsure horses have enough bedding in their stall for lying down without injury, install anti-kick devices in horse stalls, behavioral therapy techniques.
Pressure bandages
Cold hosing and/or icing the affected leg
Topical anti-inflammatoryApplied over the affected area
Surgical drainageSometimes required in serious cases, where the fluid within the swelling needs to be drained by a veterinarian as a soon as possible, followed by pressure bandaging to minimize more fluid from accumulating.
Corticosteroid injectionsIn serious cases, your veterinarian may inject a long-acting corticosteroid into the area once the fluid is drained, as an aid to help improve the chances of recovery from the injury.
