Plain-English summary
Seven dogs with hip problems due to a deficiency in the dorsal acetabular rim (the part of the hip joint) underwent total hip replacement surgery using a special plate and bone cement to support the joint. After the surgery, all the dogs showed improvement in their limping within about eight months. There were some complications, including temporary nerve issues in two dogs, but these resolved within three months. Overall, this new surgical technique helped these dogs regain better mobility and comfort.

Abstract
OBJECTIVE: To describe a surgical technique for reinforced augmentation of the dorsal acetabular rim (DAR) using a string-of-pearls (SOP™) locking plate and polymethylmethacrylate (PMMA) bone cement, and to report clinical outcome in 7 dogs. STUDY DESIGN: Case series. ANIMALS: Dogs (n=7). METHODS: Medical records (November 2009-April 2010) of 7 dogs with large DAR deficits, that had total hip replacement (THR) with reinforced augmentation of the DAR using a SOP™ plate and PMMA were evaluated retrospectively. Reinforced augmentation of the DAR involved anchorage of a precontoured 2.0 or 2.7 mm SOP™ plate dorsal to the acetabulum followed by application of PMMA cement to cover the reamed acetabulum and plate. Cemented acetabular components were used. Implant associated complications were recorded and ≥6-month follow-up obtained. RESULTS: In all dogs, lameness improved at medium-term reassessment (median, 8 months; range, 6-11 months). Complications included transient sciatic neurapraxia in 2 dogs, which resolved by 3 months. CONCLUSIONS: Reinforced augmentation of the DAR using a SOP™ plate and PMMA cement may facilitate placement of acetabular THR component implantation in dogs with severe DAR insufficiency.
