![]() Medications prescribed to treat systemic problems such as hypothyroidism should not be stopped. Should I stop all of my dog’s medications before surgery? Long-term implant stability is achieved by placing bone cement inside the bones, then securing the implants into this bed of bone cement. īiomedtrix cemented (CFX) total hip replacement implants. For more information on veterinary total hip implants, please visit. The implants are very durable, and are anchored in place using either bone cement (cemented hip replacement) or by the dog’s own bone actually growing into the implants (cementless hip replacement). The new hip is designed to allow the joint to move in an identical manner to a normal hip. The diseased part of the pelvis (socket) is replaced with a plastic or combination metal and plastic cup. The diseased femoral head (the ball) is replaced with a metal implant on a stem that fits inside the femur (thigh bone). Under general anesthesia, the surgeon removes the cartilage and bone that make up the hip joint. How does the total hip replacement procedure work? Finally, your dog must be finished growing (skeletally mature), so most dogs must be at least 10 months old before a hip replacement can be performed. If a femoral head ostectomy (FHO) has already been performed, total hip replacement is extremely challenging and the chances of success are much lower. Once these underlying problems are addressed and resolved, total hip replacement may again be considered. Other common causes of hind limb problems in dogs include rupture of the cranial cruciate ligament and neurologic problems such as intervertebral disk disease. If your dog suffers from skin, ear, dental, or urinary infections, or shows evidence of other potential sources of weakness or lameness, total hip replacement will not be performed. Radiographs (x-rays) of a dog with hip arthritis, secondary to hip dysplasia, before and after hip replacement.Īre there reasons why my dog shouldn’t have a total hip replacement? Common clues that a total hip replacement might be needed include hind limb lameness, reluctance to rise or jump, inability to exercise, pain after exercise, decreased activity, and loss of muscle mass. A complete history of how and what your dog has been doing at home will be an important part of the decision making process. How do I know if my dog needs a total hip replacement?Ī complete physical, orthopedic, and neurologic examination will be performed by an orthopedic surgeon. Many dogs with arthritic and painful hips function fairly well with pain medication and exercise restriction, but when a painful joint is removed and replaced with an artificial hip, there is often a dramatic change in the patient’s activity, lameness, muscle mass, and personality. The most frequent indication for total hip replacement in dogs is the relief of pain and lameness caused by severe arthritis secondary to hip dysplasia, or fractures (breaks) and dislocation of the bones that make up the hip joint. D) Post-op view of a hybrid THR, in which a cemented femoral component and cementless acetabular component were used. C) Post-op view of a completely cementless THR. B) Post-op view of a completely cemented THR. Total hip replacement radiographs (x-rays) A) Pre-op view of an arthritic hip. ![]() B-D) closed arrows – femoral component of THR, open arrows – bone cement thin arrows – acetabular component of THR, asterisk – remaining acetabulum. LEGEND: A) arrows – diseased femoral head, asterisk – disease acetabulum. The new artificial hip provides a pain free joint substitute, and as such, limb function and activity level return to normal. Removal of the affected hip joint eliminates the source of pain and lameness, thus allowing the patient to return to a normal level of activity. These bones are partially removed and a metal and plastic artificial implant, or “prosthesis,” is placed to function like a normal hip. The hip joint is a “ball and socket” joint made of two bones.
