An overview of avian tendon and ligament problems

Tendon is a mechanical bridge that transmits muscle strength to the bones and joints. Musculoskeletal disorders damages millions of dollars in economic losses each year to companies in the animal husbandry industry that inflict food. The tendon is mainly composed of tenocyte and tenoblast cells and is oriented and organized by collagen fibers. Viral arthritis / tenosynovitis in poultry is one of the pathological manifestations of avian reovirus infection. Viral arthritis can be diagnosed by clinical observations and serological examination and radiological findings. Studies show the effect of vaccines on the prevention of this disease. Tendon mineralization in poultry can be a part of the natural process or can be caused by aging or tendon damage. Mineral deposition in tendons makes it a hard structure with less flexibility. The morphological properties of tissue and mineralized tendon cells have been studied. Several studies on the effects of activity on avian Gastrocnemius tendon have been performed. One of the tendon injuries is related to the patagial tendon, which responds well to treatment after surgery. The tendon plays a vital role in function of birds and is damaged, which causes irreparable problems. Therefore, it is necessary to know its structure and precise function in preventing damage as well as their more effective treatment.
