Bone cysts are an emerging problem in modern horse breeding. These cavities are, in most cases, developmental disorders similar to the formation of OCD fragments. Bone cysts can occur in most bones in horses and are always located near a joint, with a connection to the involved joint. The most common cysts are found in the knee (medial femoral condyle), the pastern bone, coronet bone, and coffin bone, but can also occur in the carpus, tarsus, shoulder, etc.

The treatment of bone cysts is also continuously evolving. Depending on the location, size of the cyst, and the extent of joint communication, the surgeon can develop a treatment plan. This will always involve thorough debridement of the cyst's contents. Additionally, a vector can be placed to stimulate bone growth within the cyst. At Equitom, nearly all cyst treatments are performed under CT guidance to ensure ultra-precise placement of an implant or graft:
- Filling the cyst with autologous bone graft
- Filling the cyst with a resorbable screw
- Filling the cyst with resorbable bone cement
- Placement of a metal screw
The success of each treatment depends on the cyst itself (size, connection with the joint), the patient's age (the younger, the better the chance of success), and the condition of the involved joint (osteoarthritis decreases the chance of success).
