Dog Avascular necrosis of the femoral head occurs in puppies when they are three months of age. There is a lack of blood flow to the top of the femur bone and secondary degeneration of the hip joint. The main reason for the dog’s femoral head necrosis is that the blood flow of the femoral head is blocked and the bone ischemia caused by the damage is caused, so it can generally become avascular necrosis of the femoral head or aseptic necrosis of the femoral head. This kind of disease has a high incidence in small dogs, and our common pet dog poodle is one of the most frequent dog breeds.
Symptoms of Dog Avascular Necrosis of the Femoral Head
Dog Avascular Necrosis of the Femoral Head will appear some symptoms like slow walking, cautious movement, do not like to climb stairs, hind limb movement is uncoordinated. Dog Avascular Necrosis of the Femoral Head may also be accompanied by hip dysplasia. The specific diagnosis requires hip angle x-ray photography and ct examination. After the diagnosis of femoral head necrosis, femoral head resection or hip replacement is recommended.
Diagnosis of Dog Avascular Necrosis of the Femoral Head
1. Clinical examination: measure body temperature, heart rate and respiration; observe mental status.
2. Laboratory examination: The veterinarian begins a complete physical examination of your dog. By passing the leg through a full range of motion, the integrity of the hip joint and the stability of the hip joint and surrounding muscles can be checked. Next, an X-ray examination of the hip joint will be performed to diagnose vascular necrosis of the femoral head. In some cases, CT or MRI diagnosis may be required.
Treatment of Dog Avascular Necrosis of the Femoral Head
For the treatment of ischemic necrosis of the femoral head in dogs, the most commonly used method at present is also the most effective method to remove the pain from the femoral head and neck, and form a false joint after functional exercise, reload the weight, and gain the function. The application of drug conservative therapy can only play a role in reducing pain, and it is difficult to improve its function. Surgical treatment should be performed as soon as possible, otherwise it will lead to muscle atrophy, which is very unfavorable for postoperative functional exercise. The most important thing after the operation is to take the weight as soon as possible, and exercise rehabilitation as soon as possible. The earlier the exercise, the better the recovery effect. If the bilateral femoral heads are sick, the femoral head and femoral neck should be removed on one side, and the other side should be done 30 to 45 days after surgery.
If the affected dog’s symptoms are not very serious or if the affected dog is unable to undergo surgical treatment due to its own physical reasons, conservative treatment can be taken, that is, taking painkillers to relieve the dog’s pain and proper swimming training. However, conservative treatment usually only temporarily relieves the symptoms. When the dog’s physical condition is suitable, it is necessary to actively take surgical treatment to remove the root cause.
