Plain-English summary
A group of cats underwent a hybrid total hip replacement surgery to help with hip problems. The procedure involved using a special cemented stem and a cementless cup, and it was performed on 17 hips, including two cats that had both hips done. After the surgery, there were no complications, and follow-up reports from owners showed that their cats were doing well, with a high level of satisfaction about the results. Overall, this surgery appears to be a safe and effective option for cats with hip issues, leading to good long-term outcomes.

Abstract
OBJECTIVE: To describe the surgical technique, complications and outcome of hybrid total hip replacement (THR) in cats using a BioMedtrix cemented femoral stem and cementless acetabular cup. STUDY DESIGN: A retrospective case series. ANIMALS: Cats undergoing hybrid THR between 2020 and 2023. METHODS: The present study was a retrospective review of medical records. Postoperative radiographs were reviewed and implant positioning measured. Owner-reported follow-up was obtained via questionnaire utilizing the short-form feline musculoskeletal pain index (sf-FMPI). RESULTS: A total of 17 hybrid THRs were performed with two cats undergoing bilateral THR. A 12 mm BioMedtrix micro BFX acetabular cup was placed in all cats in combination with a CFX femoral stem. Follow up imaging demonstrated no change in implant position. No intra- or postoperative complications were reported. Hybrid THR was successfully performed in one case as a revision strategy for recurrent hip luxation following CFX THR. Owner-reported follow-up was obtained for 10 out of 15 cats (mean 438 days postoperatively; range, 185-1084 days). Overall satisfaction was excellent and the mean sf-FMPI score was 2/36. CONCLUSION: This study demonstrates that hybrid THR using a micro BFX acetabular cup is feasible in cats with a good medium to long-term outcome. These results compare favorably to previous reports of feline THR. CLINICAL SIGNIFICANCE: Hybrid THR in cats has a low complication rate and high owner satisfaction. This technique should be considered for the management of coxofemoral disease in cats and can be considered for CFX cup revision.
