What is Total Hip Replacement Surgery in Dogs?
A total hip replacement (THR) in dogs is a surgical procedure that involves the replacement of a severely damaged or diseased hip joint with an artificial component. Total hip replacement is a surgical treatment for treating severe arthritis, hip dysplasia, fractures, and dislocations. THR is widely regarded as safe and effective, with a high likelihood of significantly increasing limb function and enhancing their quality of life.
What Makes a Dog A Good Candidate For Total Hip Replacement Surgery?
Dogs who are suffering from severe arthritis, hip dysplasia, fractures, and dislocations that cannot be resolved aside from THR and are in a measurable amount of pain are usually those that received a THR. Dogs need to be in overall good health as well as have no other joint or bone issues, nerve damage/disease, or other medical illnesses. Dogs who receive THR need to be skeletally mature and finished growing which is usually between 9-12 months old. X-rays will also reveal if the size of the bones can fit a prosthesis. THR surgery is usually done on dogs over 40 pounds.
Are There Any Risks With Total Hip Replacement Surgery?
Any type of anesthetic or operation comes with its own set of hazards. These dangers will be discussed with you by your veterinarian or orthopedic surgeon. In dogs, the reported complication rate after total hip replacement is between 7% and 12%. It is crucial to identify and treat issues as soon as possible after a complete hip replacement. Swelling at the incision site (seroma) or a low-grade infection of the skin around the incision are examples of mild complications. However, there are three significant problems that might result in the hip replacement failing and requiring further surgery.
As with any infection, an infection of the impact is something that should be taken very seriously. While skin or wound infections may be able to be controlled with antibiotics, infections of the actual implants require the implant being removed and replaced.
There’s a possibility of the implants losing due to either “aspect loosening” or low-grade infection. Aspect loosening is when the patient’s body rejects the implant and occurs in about 5-15% of cases. If aspect loosening occurs, the implant needs to be removed and/or replaced.
Luxation or Dislocation of the Implants
Luxation or dislocation of the implants is fairly rare is occurs in only about 2-4% of patients and usually within the first 3 weeks post-surgery. If this happens, another surgery under anesthesia will be required to fix it.
What Happens During Total Hip Replacement Surgery?
THR surgery for severe arthritis, hip dysplasia, fractures, and dislocations surgery is a multi-day process. To prepare for general anesthesia, most dogs getting a complete hip replacement will have a comprehensive examination and a blood test profile.
Total hip replacement surgery takes two to three hours on average, and your dog may need to stay in the hospital for one to three days afterward. A 12-week recuperation time is expected. Even though your dog’s hip dysplasia affects both hips, surgery on one hip at a time is possible, providing 3 to 6 months of healing time in between procedures.
During the actual surgery, the ball (head of the femur) and socket (acetabulum) are removed and replaced with prosthetic implants. The acetabular socket will be rebuilt and equipped with a polyethylene cup, while the stem and ball are constructed of cobalt-chromium. Bone cement may or may not be used to hold the implants in place, depending on the implant type chosen by the surgeon for your pet.
Around 90% to 95% of dogs that receive a complete hip replacement perform really well and have outstanding function. Every operation has some risk, but your dog’s surgeon will do all in his power to avoid any complications. Hip dislocation, implant loosening, infection, and nerve injury are all rare problems that can typically be easily addressed.
How Do You Care for a Dog Post-Total Hip Replacement Surgery?
When dogs are released from the hospital a few days after having total hip replacement surgery, it’s crucial to ensure proper healing. Stitches or staples will usually be removed in 10-14 days following surgery. Your veterinarian will also provide a pain management regimen which might include pain medication and crate rest or confined to a small area during recovery for about 3 months. While dogs are usually able to bear weight on the limb fairly soon after surgery, their activity must be closely monitored and activity limited to being on a leash when not in confinement to prevent over-exertion. Each veterinarian will provide their own post-op instructions and they should be followed as closely as possible for best results.
How Much Does Total Hip Replacement Surgery Cost?
Due to the involvement and difficulty of canine total hip replacement surgery, it comes out to being one of the most expensive veterinary surgeries. It comes out on average to being $3,500 to $7,000 per hip or if both hips need to be replaced (which is often the case), the cost runs on average $7,000 to $14,000. This is an instance when having pet insurance can offset the high cost.
How Can Total Hip Replacement Surgery Be Prevented?
Preventing total hip replacements comes with preventing the reason for needing the surgery. So essentially working to prevent hip dysplasia and severe arthritis. One way to stay on top of the causes that result in THR is having regularly scheduled vet appointments.
