Plain-English summary
A group of 39 puppies with hip dysplasia underwent a surgery called juvenile pubic symphysiodesis (JPS) to help improve their condition. After two years, the puppies that had the surgery showed little increase in arthritis and significant improvement in hip function, while the untreated puppies experienced worsening arthritis and no improvement. The surgery was particularly effective for puppies with mild to moderate hip laxity, helping to reduce pain and improve mobility. Overall, JPS proved to be a safe and effective treatment for young puppies at risk of hip dysplasia.

Abstract
OBJECTIVES: To determine the clinical effects of juvenile pubic symphysiodesis (JPS) treatment in hip dysplasia-prone puppies with comparison to similar untreated control puppies. DESIGN: Controlled clinical case study. ANIMALS: Thirty-nine dysplastic puppies, of which six were part of the control group, with a positive Ortolani or hip distraction index (DI)≥0.40. PROCEDURES: The following eight clinical tests were evaluated preoperatively, and at one and two years postoperatively: Ortolani, hip reduction angle (HRA), gait evaluation, osteoarthritis, hip pain, and three Norberg angles (angle-extended mode [N-OFA], angle-compression mode [N-COM], and angle-distracted mode [N-DIS]). Juvenile pubic fusion (JPS) was performed by unipolar electro-cautery at 12 to 24 weeks of age; the control puppies received a sham operation. RESULTS: For the JPS puppies, the mean osteoarthritis level did not significantly increase (11%). There was a 74% reversal of preoperative positive Ortolani signs. Hip reduction angle, DI and N-DIS also improved significantly. Only N-DIS fully detected Norberg angle laxity. Within the control group, osteoarthritis increased significantly (55%) with no improvement in Ortolani incidence, N-OFA or N-COM angles. A decrease in HRA and DI was associated with increased osteoarthritis levels. Signs of hip pain increased by 33%, which was not significant. Dogs with initial severe hip laxity (DI≥0.70) experienced progressive osteoarthritis. CONCLUSIONS AND CLINICAL RELEVANCE: In JPS dogs with preoperative mild to moderate hip laxity (DI = 0.40-0.69), insignificant osteoarthritis occurred at two years. Juvenile pubic symphysiodesis surgery also improved other clinical criteria (Ortolani, HRA, hip pain, N-DIS). Osteoarthritis was generally not prevented by JPS in dogs with initial severely lax hips (DI≥0.70). Juvenile pubic symphysiodesis surgery at 12 to 24 weeks of age was an effective and safe pre-emptive bilateral treatment for mild to moderate hip dysplasia.
