Plain-English summary
A group of 24 dogs with hip dysplasia underwent a surgical procedure called double pelvic osteotomy (DPO) to help improve their hip joint stability. Before the surgery, the dogs showed significant subluxation (misalignment) of the femoral head, but after the procedure, follow-up scans revealed a marked improvement in their condition. The dogs had a substantial increase in hip joint stability immediately after surgery and maintained good results at follow-up. This suggests that DPO is effective in reducing hip joint misalignment in dogs with hip dysplasia.

Abstract
OBJECTIVE:  The aim of this study was to determine the effect of double pelvic osteotomy (DPO) on dorsolateral subluxation (DLS) of the femoral head in a weight-bearing position. STUDY DESIGN:  Retrospective observational study with treatment effect analysis. Twenty-four client-owned dogs that underwent DPO due to hip dysplasia. METHODS:  Computed tomography (CT) studies were performed on 24 dogs that underwent a DPO between 2015 and 2021. The patients were positioned with the femora in a weight-bearing position. The DLS score was measured pre-DPO, immediately post-DPO, and at follow-up to determine if DPO resulted in an increase in the DLS score. RESULTS:  A total of 21 dogs underwent single-stage bilateral DPO and 3 dogs underwent unilateral DPO resulting in 45 hip joints available for analysis. Follow-up CT was available for 29 of these at a median of 51 days (range: 35-482 days). The mean DLS score was 36.1% ± 14.6 preoperatively, 71.4% ± 12.5 post-DPO, and 70.0% ± 15.3 at follow-up. The increase between the pre- and postoperative measurement was significant ( < 0.001). CONCLUSION:  DPO results in reduced subluxation of the femoral head in a weight-bearing position. CLINICAL SIGNIFICANCE:  The in vivo results suggest that DPO will result in reduced femoral subluxation during weight-bearing.
