JPS: An Exciting New Treatment for Canine Hip Dysplasia

Canine Hip Dysplasia (CHD) is one of the most common orthopedic diseases of large breed dogs. In affected dogs, joint laxity (looseness), joint incongruence and secondary arthritis can lead to crippling pain. Many surgical options have been proposed to treat CHD in young dogs. However, traditional surgical techniques are invasive, can be associated with significant pain, and are expensive for dog owners.

What is Juvenile Pubic Symphysiodesis?

Juvenile Pubic Symphysiodesis (JPS) is a new minimally invasive surgical procedure for treatment of hip dysplasia in young dogs. During JPS surgery, Electrocautery is applied to the growth plate of the pubis (part of the pelvic bone) inducing bony fusion. During the dog’s normal growth after surgery, pubic fusion results in angular changes to the pelvis. These changes allow for a better fit of the ball and socket hip joint, resulting in significant improvements in hip conformation.

Juvenile pubic symphysiodesis involves inducing premature closure of the pubic symphysis by thermal necrosis. Veterinary surgeons recommend that dogs be at least 16 weeks of age for the surgery to be beneficial, but most dogs that develop hip dysplasia do not have physical signs at this time. Therefore, it is recommended that dog breeds susceptible to hip dysplasia be tested using radiographs to identify the loose hips.

Juvenile Pubic Symphysiodesis Procedure in Dogs

In a juvenile pubic symphysiodesis procedure, the pubic bone is destroyed with electrocautery, as this portion of the pelvis no longer grows. The remaining parts of the pelvis is then allowed to grow around the acetabulae that rotates the socket of the hips, over the ball of the hip. The result of this procedure is a stable hip and a decreased chance of the canine developing chronic arthritis later in life. An overview of the surgical procedure used to complete juvenile pubic symphysiodesis in dogs is provided below:

  • The dog will be placed under general anesthesia
  • Between the hind legs, a small incision will be made in order for the vet to visualize the pelvis pubic bone.
  • Cauterization is used on the dog’s pelvis bone to destroy cells that are growing on the growth plate, ideally stopping the bone abnormality.

JPS surgery is short in duration and requires no orthopedic implants. The post-operative period may involve a little discomfort, which can easily be treated.Typically, dogs spend only one night in the hospital after JPS surgery and can return to normal activity in as little as 2 weeks.

Efficacy of Juvenile Pubic Symphysiodesis in Dogs

Juvenile pubic symphysiodesis is a highly effective procedure used to treat dogs with hip dysplasia. Canines that have had this procedure performed at an ideal age have a good chance of obtaining a positive recovery. If the procedure was completed when the canine was 16 weeks of age or younger, the dog has a lesser chance of developing arthritis within the hips.

JPS should be performed at an early age (15-20 weeks) to affect larger and more rapid changes in hip joint confirmation. JPS surgery has been performed in puppies as young as 12 weeks old with excellent results. By performing the surgery at an early age, it is possible to slow or stop the progression of osteoarthritis in dogs with hip dysplasia. JPS surgery can easily be combined with your dog’s neutering or spaying

Juvenile Pubic Symphysiodesis Prevention in Dogs

Juvenile pubic symphysiodesis is a procedure used to treat dogs with hip dysplasia, a genetic disease that cannot be prevented. Dogs develop this abnormality due to a deformity found within the genetic makeup of one or both of the offspring’s parents. Common dog breeds affected by hip dysplasia include the golden retriever, German shepherd, rottweiler and Labrador. It is highly recommended to sterilize the canines that have undergone juvenile pubic symphysiodesis surgery and those found with the hip abnormality that have not yet undergone the procedure.
