Fistulous withers

Fistulous Withers is a condition that affects the withers of a horse. It is characterized by the formation of a fistula, or abnormal connection, between two body parts. In the case of Fistulous Withers, the fistula forms between the skin and the underlying structures of the withers, including the spinal processes and associated ligaments and muscles.

Causes

Fistulous Withers is typically caused by a bacterial infection, most commonly Brucella abortus, which is also responsible for Brucellosis in cattle. The bacteria can enter the body through a wound or abrasion on the skin, and then travel to the withers where they cause inflammation and the formation of a fistula.

Symptoms

The main symptom of Fistulous Withers is a persistent, draining wound on the withers of the horse. The wound may initially appear to heal, but then reopens and continues to drain. Other symptoms can include fever, lameness, and loss of appetite.

Diagnosis

Diagnosis of Fistulous Withers is based on the clinical signs and the results of a bacterial culture of the draining fluid. Radiographs and ultrasound may also be used to assess the extent of the condition and to guide treatment.

Treatment

Treatment of Fistulous Withers involves a combination of antibiotics to treat the bacterial infection, and surgical removal of the fistula and any infected or damaged tissue. After surgery, the wound is typically left open to heal by secondary intention, which allows for drainage and reduces the risk of further infection.

Prognosis

The prognosis for Fistulous Withers is generally good with appropriate treatment, although the condition can be difficult to treat and may recur. Early detection and treatment can improve the prognosis.

Prevention

Prevention of Fistulous Withers involves good horse care, including regular grooming to prevent skin abrasions, and prompt treatment of any wounds or injuries.
