A 7-year-old, intact female Jindo dog was presented for assessment of weight-bearing lameness of the righthindlimb. On physical examination, crepitus and pain was noted in the right coxofemoral joint upon extension. Radiographs revealed a craniodorsal luxation of the right coxofemoral joint and degenerative joint disease (DJD) ofboth coxofemoral joints. Total hip replacement (THR) was performed for the right coxofemoral joint. Intraoperatively,dorsal acetabular rim (DAR) deficiency was noted, which can be related to a high risk for acetabular cup implantdislocation. Deficiency of the dorsal acetabular rim realigned with the acetabular cup using universal locking plate(ULP) and polymethylmethacrylate (PMMA) bone cement. After surgery, the patient had an uneventful course anda successful outcome. The ROM and thigh girth were dramatically improved. There were no complications associatedwith prosthesis implants. Hip luxation with dorsal acetabular rim deficiency in a dog was successfully repaired withTHR and dorsal acetabular rim augmentation using ULP and PMMA bone cement. This technique should be consideredwhen conventional THR is precluded by dorsal acetabular rim deficiency.
