Hybrid cemented/cementless total hip replacement in dogs: seventy-eight consecutive joint replacements

Area of Science:

• Veterinary Orthopedics
• Surgical Innovation
• Canine Health

Background:

• Total hip replacement (THR) is a common surgical procedure for managing hip joint disease in dogs.
• Traditional THR techniques utilize either fully cemented or cementless implants.
• The hybrid THR approach combines different fixation methods for acetabular and femoral components.

Purpose of the Study:

• To evaluate the clinical efficacy and safety of a hybrid total hip replacement (THR) technique in dogs.
• To assess the complication rates associated with hybrid THR.
• To determine long-term owner satisfaction with hybrid THR outcomes.

Main Methods:

• A prospective case series involving 71 client-owned dogs undergoing 78 hybrid THR procedures.
• Hybrid THR utilized a cementless acetabular component and a cemented femoral component.
• Pre- and postoperative radiographic features, pain scores, and lameness scores were recorded.
• Longer-term outcomes were assessed via owner questionnaires.

Main Results:

• A low major complication rate of 5% was observed, with most resolved after revision surgery.
• Significant improvements in lameness and pain scores were noted at 4 and 12 weeks postoperatively.
• Long-term follow-up (mean 16 months) reported no further complications.
• High owner satisfaction was reported for the majority of hybrid THR procedures.

Conclusions:

• Hybrid total hip replacement (THR) is a safe and effective surgical option for dogs.
• This technique demonstrates a low complication rate and favorable long-term outcomes.
• Hybrid THR provides a valuable alternative to conventional cemented or cementless hip implants in veterinary surgery.
