Gorman HA A new prosthetic hip joint.

The cranial approach has been used most widely and has been described by Olmstead and co-workers. In this procedure the femoral head is excised using the prosthesis as an overlay to determine the proper length and angle for the osteotomy of the femoral neck.

Leighton RL: The Richards II canine total hip prosthesis.

The total hip is the most widely used and most successful total joint prosthesis in humans.

The complete answer has not been found, and the optimal design for an implant using PMMA or biologic ingrowth has not yet been discovered.In humans the loosening of the cup and stem of the total hip joint prosthesis still represents a significant problem, especially in the younger, more active patient.

Canine total hip prosthesis: a case report.

All other total joint prostheses have a less optimal performance record.In the dog the clinical documentation of total hip prosthesis has been very limited.

Total Hip Replacement Surgery (THR) in Dogs and Cats

The gradual shift to the metal-polyethylene wear interface seemed to do much to solve the problem of wear, but loosening has continued to be a significant complication of long-term use in humans.There has been much less experience with canine total joint replacement. Although endoprostheses for hip replacement had been used previously with relatively poor results, the first total joint replacement for use in the dog was developed by Gorman. This total hip joint, which consisted of an interlocked ball and socket joint, was attached to the acetabulum with three screws and into the medullary cavity of the femur with a simple long stem following manual reduction.

Does my dog need a Total Hip Replacement (THR)

A full general examination and orthopedic evaluation should be performed due to the possibility of concurrent trauma. The force required to produce hip luxation can also damage the urinary system, lungs, heart, or other body organs. Additional diagnostics are needed to assess the patient for other injuries or organ conditions which may affect anesthesia. Additional blood work is indicated to fully assess organ function, identify the extent of damage, identify pre-existing medical problems, and for anesthetic planning.

FAQ: Total Hip Replacement | Veterinary Medical Center

More recently studies have been designed using primarily animal models. Clinical total hip replacement in the dog has evolved from the use of the dog as a model for a device that could be applied to humans, into a form of treatment for the animal with debilitating joint disease.

ask your doctor about the hip replacement prosthesis.

Although 91.2% of the dogs with total joint replacement had a satisfactory result at their latest evaluation, this number may be misleading when describing the total population of 221 total joint replacements reported in the article, since 11.7% of the dogs were lost to followup, 7.2% of the dogs had their prosthesis removed, and 13.5% of the dogs were already dead for whatever reasons.


At this time (late 1960s-early 1970s), a number of dog studies were instituted using old designs incorporating the use of PMMA for cementing the device into the bone.2 New designs were also presented that made use of the ability of the PMMA to stabilize the prosthesis

Thus, the best results can be expected in dogs in the 18kg to 35-kg range, which fortunately includes those breeds affected most profoundly by hip dysplasia.
