Equine Sesamoiditis 

Sesamoiditis is an inflammation of the sesamoid bones which are located behind the bones of the horse’s fetlock helping to keep the tendons and ligaments functioning.  Sesamoiditis causes pain and bone growth.  Sesamoiditis most often affects show jumpers and race horses.


Symptoms of equine Sesamoiditis

  1. Warmth in the affected area
  2. Enlargement of the affected area
  3. Pain on palpation
  4. Lameness


Causes of equine Sesamoiditis
Sesamoiditis is generally caused by
1. Excess stress on the fetlock joint often caused by long pasterns or long toes and low heels can result in Sesamoiditis
2. Bad shoeing
3. A genetic component may exist with Sesamoiditis
4. Excess weight
5. Possible faulty blood supply to the bone


Treatment of equine Sesamoiditis
An X-ray combined with clinical signs is the best way to diagnose equine Sesamoiditis. 
Your veterinarian will recommend some of the following treatments for Sesamoiditis:

  1. anti-inflammatory medication
  2. cortisone injections
  3. intra-articular treatment of the fetlock joint with hyaluronic acid
  4. strapping to immobilize the big toe
  5. orthotics to take pressure off the affected area e.g.

egg bar shoes with squared toes further reduces Sesamoiditis stress or paten shoes      which help by lifting the heels

  1. cryotherapy
  2. shockwave therapy
  3. local Tildren injections
  4.  light workload until the damaged tissue has recovered
  5. strong elastic bandage around the joint.
