Hip replacement is a surgical procedure performed in dogs and cats as a salvage procedure, to alleviate severe pain in the hip due to, for example, hip dysplasia or irreparable bone fracture. [ 1 ] [ 2 ] The procedure replaces the head of the femur and the acetabulum with prosthetic implants. [ 1 ]
A good candidate for total hip replacement (THR) must be at least 9–12 months old to be sure he has finished developing and weigh at least 30 pounds (14 kg). The hip implant for dogs is similar to its human counterpart, but it is much smaller. X-rays are used to determine the dimensions of an appropriately sized implant. [3]
A total hip replacement (total hip arthroplasty) consists of replacing both the acetabulum and the femoral head while hemiarthroplasty generally only replaces the femoral head. Hip replacement is one of the most common orthopaedic operations, though patient satisfaction varies widely between different techniques and implants. [2]
Hip replacement can be performed as a total replacement or a hemi (half) replacement. A total hip replacement consists of replacing both the acetabulum and the femoral head while hemiarthroplasty generally only replaces the femoral head. Hip replacement is currently the most common orthopaedic operation, though patient satisfaction short- and ...
It may be used in some cases of hip dysplasia, an extremely painful congenital condition found in many dog breeds and some cats. [4] It is also performed in cases of trauma where the head of the femur is badly broken or severed, or in response to other diseases of the hip bone, such as Legg-Calve-Perthes' disease. It is sometimes the procedure ...
Hip dysplasia in a Labrador Retriever Normal hips, for comparison. In dogs, hip dysplasia is an abnormal formation of the hip socket that, in its more severe form, can eventually cause lameness and arthritis of the joints. It is a genetic (polygenic) trait that is affected by environmental factors.
The modified posterior MIS approach to hip resurfacing and total hip arthroplasty (hip replacement) displays a host of advantages to the patient: Less post-operative pain; Less soft tissue damage and pressure on muscle fibres. Shorter hospital stay; Lower blood loss; Smaller incision; Quicker return to work and functional activities [2]
Hip resurfacing is a surgical alternative to total hip replacement (THR). The procedure consists of placing a cap (usually made of cobalt-chrome metal), which is hollow and shaped similarly to the cap of a mushroom, over the head of the femur while a matching metal cup (similar to what is used with a THR) is placed in the acetabulum (pelvis socket), replacing the articulating surfaces of the ...
