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.
