In this Simini Small Animal Surgery Podcast episode, we highlight three studies from the August 2025 issue of Veterinary Surgery, each tackling challenges in total hip arthroplasty (THA) across species and surgical phases—from candidacy in tiny dogs to implant selection in cats, to fracture prevention in everyone else.We cover:✅ Kimura et al. — A study of dogs under 4 kg undergoing mini cementless THA using the Zurich system. With a 100% implant survival rate and rapid return to function, the study supports THR over FHNE—even in the tiniest patients, as long as careful planning and imaging guide the approach.✅ Lomas et al. — A case series of 17 hybrid total hip replacements in cats using a cemented femoral stem and cementless acetabular cup. Zero complications, excellent owner-reported outcomes, and a promising revision strategy make this technique a viable option for feline coxofemoral disease.✅ Pfund et al. — A retrospective analysis of 224 dogs identifying the Cortical Thickness Index (CTI) as a strong predictor of perioperative femoral fractures during THR. Lower CTI values were significantly associated with increased fracture risk, making CTI a reliable, reproducible pre-op screening tool.🎓 Journal Articles Discussed:Kimura et al. — Long-term outcomes of 10 dogs weighing less than 4 kg after Zurich mini-cementless total hip arthroplastyLomas et al. — Medium-term outcomes of hybrid total hip arthroplasty in cats: Cemented femoral stem and cementless acetabular cup in 17 hips (2020–2023)Pfund et al. — Femoral cortical thickness index in a population of dogs undergoing total hip replacement 📚 From the August 2025 issue of Veterinary Surgery🎁 Learn more about Simini Protect Lavage or request a sample: 👉 www.simini.com 👉 Request a Sample
