Juvenile Pubic Symphysiodesis
What is JPS - Juvenile Pubic Symphysiodesis?
Meet Baloo, the German Shepherd. Baloo was 4 months of age when he had a Juvenile Pubic Symphysiodesis (JPS) surgery performed at Marlin Coast.
Baloo required this surgery to improve hip development and reduce osteoarthritis development after being diagnosed with hip dysplasia.
Hip dysplasia means that the puppy’s hips have abnormal development, resulting in a shallow socket and loose joints. These joints are prone to subluxation (partial dislocation) leading to an early onset of arthritis causing pain.
JPS surgery is a minimally invasive, prophylactic surgical procedure performed when a puppy is between 14-20 weeks old. During this procedure we close the growth plate in the floor of the pelvis, altering movement during the puppy’s growth. As the pelvis develops, the growth plate closure leads to the hip socket rotating over the femoral head (ball of the hip joint). This additional rotation increases the coverage of the hip joint and provides more stability.
These puppies are diagnosed via screening xrays and/or by identifying hip pain at their 10-12 week or 16 week vaccination. Xrays allow us to determine the degree of hip subluxation and determine the risk of the puppy developing hip osteoarthritis. Following JPS, 80% of dogs will have significant improvement and lessen the chance of needing advanced surgery or pain killers as an adult.
The day after Baloo’s procedure he was back to his normal playful self. Puppies recover well from this procedure with minimal to no pain post-operatively.
