Summary
Modular hybrid total hip arthroplasty in dogs showed excellent limb functionality. While complications occurred, the procedure generally provided good outcomes for canine hip replacement.
Area of Science:
- Veterinary Surgery
- Orthopedics
- Canine Hip Arthroplasty
Background:
- Prospective experimental study evaluating modular hybrid total hip arthroplasty in dogs.
- Assesses surgical procedure and outcomes in a canine model.
Purpose of the Study:
- To evaluate the surgical technique and clinical results of modular hybrid total hip arthroplasty in dogs.
- To determine the efficacy and safety of this specific arthroplasty technique in a canine population.
Main Methods:
- Ten skeletally mature mongrel dogs (19-27 kg) underwent surgery.
- Utilized cemented modular femoral stems and uncemented porous-coated acetabular cups.
- Clinical and radiographic assessments were conducted at multiple time points up to 360 days post-operation.
Main Results:
- Seven out of ten dogs demonstrated excellent weight-bearing in the operated limb.
- Two dogs experienced dislocation and prosthesis loosening, treated with femoral head osteotomy.
- One dog sustained a femoral fracture, managed with implant removal and femoral osteosynthesis.
Conclusions:
- Canine modular hybrid total hip arthroplasty offers excellent limb functionality.
- The procedure demonstrates potential for successful canine hip replacement despite occasional complications.
