(February 2012) (Learn how and when to remove this template message) Tibial dyschondroplasia (TD) is a metabolic disease of young poultry that affects the growth of bone and cartilage. Often occurs in broilers (chickens raised for meat) and other poultry which have been bred for fast growth rates.
The damage may destroy the myelin sheath that protects and insulates the nerve, or part of the nerve cell (the axon). This damage reduces or prevents the movement of signals through the nerve. The tibial nerve is often injured by pressure from a ligament on the inner part of the ankle. Injury or disease of structures near the knee may also damage the tibial nerve. The tibial nerve may also be affected by diseases, such as diabetes, which damage many nerves. In some cases, no cause can be found.
