Objective
To describe the surgical technique using power-assisted femoral preparation and clinical outcome in 41 dogs and 2 cats surgically treated with the micro total hip prosthesis.
Study Design
Retrospective case series
Animals
Dogs (n = 41) and 2 cats
Methods
Medical records (January 2007–March 2010) of dogs and cats that had MicroTHR were reviewed. Data regarding implant position, cement mantle quality, concurrent surgery, intra- and postoperative complications, operative time, 3-week and 3-month recheck physical examinations, 3-month pelvic radiograph findings, and interval from surgery to any complication were retrieved.
Results
Six dogs had staged bilateral MicroTHR, 35 dogs and 2 cats had unilateral MicroTHR. Median body weight was 8.2 kg (range, 2.1–14.2 kg) whereas for those that had complications (fracture or luxation) it was 8.6 kg (range, 6.6–14.1 kg). Median operative time was 71 minutes (range, 55–105 minutes). Complications included luxations (5 of 49; 10%) and femoral fracture (1; 2%). Lameness grades assigned at the 3-month recheck examination: 39 (80%) animals were grade 1, 6 (12%) were grade 2, and 4 (8%) were grade 3. Forty-five animals (92%) had good or excellent results.
Conclusions
MicroTHR is a practical and effective surgery in small breed dogs and cats with coxofemoral disease.
