Summary
Nano total hip replacement (NanoTHR) in small dogs showed good outcomes, but 33% experienced complications like fractures. Further research is needed for this alternative to FHO surgery.
Area of Science:
- Veterinary Orthopedics
- Small Animal Surgery
Background:
- Coxofemoral disease is common in toy breed dogs.
- Femoral head and neck ostectomy (FHO) and medical management are current treatment options.
Purpose of the Study:
- To evaluate the short-term clinical outcomes of nano total hip replacement (NanoTHR) in dogs.
- To identify complications associated with the NanoTHR procedure.
Main Methods:
- Retrospective case series of 12 dogs that underwent NanoTHR.
- Review of medical records for signalment, surgical details, complications, and 3-month postoperative outcomes.
- Lameness scoring and radiographic assessment were utilized.
Main Results:
- The study included small breeds, primarily Yorkshire Terriers and Toy Poodles, with a median weight of 4.87 kg.
- Complications occurred in 33% of dogs, including femoral fractures (n=3) and acetabular implant displacement (n=1).
- At 12 weeks, 58% of dogs had grade 1 lameness and 33% had grade 2 lameness, with improvements noted after revision or conservative management.
Conclusions:
- Despite a 33% complication rate, all dogs achieved good-to-excellent outcomes.
- NanoTHR shows potential as an alternative to FHO for toy breed dogs, pending technique refinement.
- Larger studies with longer follow-up are necessary to fully assess NanoTHR efficacy.
