What does THR surgery entail?
A THR involves removing both the arthritic ball (femoral head) and socket (acetabulum) and replacing them with an artificial ball and socket joint.
The surgical procedure is precisely planned using several radiographic (X-ray) views and specialized templates that match the available implant sizes.
The average length of a THR surgical procedure is approximately 75 minutes.
During surgery, the arthritic femoral head is removed, the arthritic acetabulum is prepared, and the acetabular component (socket) is implanted. Next, the femur is prepared, and the femoral component (stem) is implanted. The femoral head (ball) is placed on the femoral stem, and the new joint is articulated by placing the femoral head (ball) within the acetabulum (socket).
What is the typical recovery time for THR and what is involved?
Dogs often begin using their operated limb on the day of surgery. Most dogs use their operated leg quite well within a couple of weeks but activity should be supervised and limited to leash walks for approximately six weeks after surgery.
How long will my dog be in the hospital following THR surgery?
Most veterinarians keep dogs for one to three days following surgery. In some rare instances, high-risk patients may be hospitalized for longer periods to provide additional assistance or to protect the stability of the new prosthetic joint.
How is the total hip replacement procedure performed in the clinic?
Dog needs to be brought to the clinic for medical examination and assessment of advisability of total joint replacement. If surgery is deemed necessary, an anesthesiologist’s consultation is needed in order to schedule a pre-surgery evaluation. If no contraindications to general anesthesia exist, the date of surgery is scheduled. The owner is requested to wash the dog just before the surgery, and to start giving antibiotics. The dog is to be admitted to the clinic and stay in our in-patient unit for the whole period of surgery and post-operative observation. Duration of in-hospital stay rarely exceeds 7 days. After discharge we will monitor the implant condition by X-ray on days 14, 30, 60, and then 6 months after surgery; thereafter, follow-up orthopedic exams are performed yearly.
How to make a right decision pro or contra total joint replacement?
Total joint replacement is not an urgent surgery, so decision should be balanced and based on specialist advice.
How do I know that my dog needs joint replacement?
Failure of medical treatment and irreversible joint damage.
Is it possible to manage joint diseases without joint replacement?
Most orthopedic diseases can be successfully managed without prosthetic repair.
How do I know that my dog has a joint problem and needs to be examined by veterinary orthopedist?
Gait disturbances, rapid fatigue and reluctance to move as it normally would, for example to jump or walk upstairs, are all the obvious signs of an orthopedic problem.
Is it possible and necessary to replace a joint at an early stage of progressive joint disease?
No; joint sparing treatment to the fullest extent possible should be attempted.
Is total joint replacement a last-resort option, when other treatment methods have failed, or a treatment option for joint disease?
Yes, it is a last-resort option, when salvage of native joint is unfeasible, and conservative treatment is ineffective.
What is the success rate for canine THR procedures?
The success rate is very high. More than 95% of the patients who receive a THR should be able to use the new hip for the rest of their lives.
How common are THRs in dogs?
The first THR in a dog was performed in 1957. Since their introduction in 1990, over 54,000 procedures have been performed using BioMedtrix implants. THR can be performed on dogs ranging from five through 170 pounds, and also on cats.
What are the clinical signs of hip dysplasia?
The signs of hip dysplasia may be subtle. They can include the presence of lameness in one or both hind legs and the reluctance to climb stairs or jump. Dogs that are affected often become less active and less playful. They may be reluctant to go on walks and their gait may be a “bunny hop” at certain speeds.
What is hip dysplasia?
Hip dysplasia is an abnormal development and growth of the hip joint. Both hips are usually affected but symptoms may be more severe on one side. Hip dysplasia is manifested by varying degrees of laxity (looseness) of the hip joint with instability and malformation of the joint components. Arthritis is the long-term consequence of hip joint laxity.
What are indications for total hip replacement?
Severe degenerative joint disease (arthrosis), for example due to hip dysplasia, Perthes disease and femoral neck fracture are among the most common reasons for total hip replacement.
What is canine total hip replacement (THR)?
Canine THR is a surgical procedure in which the arthritic hip joint surfaces are replaced with a new prosthetic ball and socket. The prosthesis is designed to fit precisely and mimics the anatomy of the original joint. The arthritic joint is pain free after total hip replacement.
BioMedtrix proudly introduced the CFX® (Cement Fixation) Total Hip System in 1990, and the BFX® (Biologic Fixation) system in 2003. Since then, over 54,000 procedures have been performed. The implants in each system are interchangeable and are prepared to a common surgical preparation with a common set of instruments, providing greater versatility in the clinical options for total hip replacement.
