ROGY OF THE FINGERY OF THE FINGERY YELLOW
The decay of the horn of the finger crumb (necrosis cornea pulvinus digitalis) is often observed in horses and is called rotting rot.
Etiology. The leading role in the onset of the disease is the strong maceration of the horn of the crumb under the action of the products of the decomposition of urine and feces contained in the slurry. This promotes leaching, softening and loosening of the horn, and the effect of putrefactive microflora leads to its destruction and development of the septic process.
Predisposing factors are the violation of the hoof and blood supply to the basis of the crumb skin against hypodynamia, the absence or incorrect hoof trimming (excessive cutting of the horn of the crumb). Pelvic limbs are more often affected.
Pathogenesis. The prolonged exposure to the horn of the crumb of ammonium compounds, moisture and proteases released by the microflora leads to the destruction of the horn of the crumb, resulting in a purulent inflammation of the producing base layer of the skin, which usually takes a chronic course. The septic process, in turn, contributes to the detachment of the horn of the crumb.
Clinical signs. In the initial stage of the disease, lameness is usually absent, it appears only when the horn of the arrow and the outcroppings of the skin base are significantly destroyed. Lameness is increased when the animal moves on soft ground. The struck horn of the crumb swells, becomes friable, dark gray, with
extensive areas of destruction and release of sticky exudate with an unpleasant odor.
Diagnostics. The diagnosis is based on clinical signs.
Treatment. Patients are isolated in a clean dry room. After the toilet, the hooves are cleared, removing the entire exfoliated horn. The nude base of the skin is treated with a 3% solution of hydrogen peroxide, 3 ... 5% alcoholic solution of formalin or tar, and a dressing is applied.
For prevention purposes, in premises containing animals, it is necessary to maintain optimal microclimate parameters, regularly carry out hoof treatment in baths with 10% copper sulfate solution or 5% formalin solution.
DISEASES IN THE AREA OF THE TRAVELING SURGER
The joint of the first phalange is formed by the metacarpal (metatarsal), prostate and sesamoid bones. The synovial membrane of the articular capsule has clearly defined pivots. Lateral and medial evacuations are located in the horse between the metacarpal (metatarsal) bone (behind) and the corresponding leg of the interosseous middle muscle (front). Above the pocket of the turn reaches the level of the thickened edge of the slate. Its posterior wall is adjacent to the anterior wall of the digital tendon sheath. The smaller dorsal eversion is located under the tendon of the common extensor of the finger. The subcipital synovial cortex is adjacent to it.
In cattle, the 111 and IV fingers of the fingers are articulated with the main metacarpal (metatarsal) bone. Two sesamoid bones take part in the formation of the joints behind them. Capsules of both joints immediately behind both metacarpal (metatarsal) bones, where they are close, communicate with each other.
Wound joint wound
The wound joint (vulnera phalangis primae) is often seen in horses.
Etiology. Perforation of the joint capsule with cutting, stitching objects.
Clinical signs. The most important symptom, as in the wounding of other joints, is the outflow of synovia.
The prognosis with timely intervention (early surgical treatment of the wound, prevention of infection) is favorable. In such cases, it is possible to keep the aseptic wound after the operation under the bandage, and also when the joint is immobilized.
Diagnostics. In order to clarify the diagnosis, an arthropospension is made from the opposite side. The flow of injected fluid through the wound can significantly differentiates the damage of the joint capsule from the perforation of the tendon sheath.
Treatment. Early surgical treatment of the wound and prevention of infection are needed.
