Abstract:
To evaluate the clinical outcomes of total hip replacements (THR) utilizing a BFX lateral bolt stem in dogs with coxofemoral joint disease. Study design Retrospective study. Sample population A total of 149 dogs representing 195 THR. Methods Consecutive THRs utilizing a BFX lateral bolt stem were studied. Preoperative, immediate postoperative, 1‐, 2‐, 3‐, 4‐, and 12‐month postoperative radiographs were performed. All major and minor complications, revisions, outcomes, subsidence, canal flare index (CFI) were recorded. Results An intraoperative complication rate of 11.8% was observed. The postoperative complication rate was 13.6%, with 9.2% major and 4.4% minor complications. Complications included: postoperative femur fractures (3.6%), coxofemoral luxation (3.6%), stem failure (0.5%), septic loosening (0.5%), aseptic loosening (0.5%), and acetabular fracture (0.5%). Three dogs underwent prophylactic plating after subjective assessment of cortical thickness. Five of 195 (2.6%) cases underwent explant of their prostheses (median = 3 months). Mean stem subsidence at 1 month postoperatively was 1.22 ± 0.16 mm. An increased CFI was associated with postoperative femur fractures ( p 〈 .05). A total of 190 of 195 (97.4%) cases returned to normal function in the long‐term follow‐up period. Conclusion Use of the BFX lateral bolt stem resulted in minimal postoperative subsidence, a low femoral stem complication rate, and a high rate of achieving normal limb function. Clinical significance The BFX lateral bolt stem should be considered in canine THR as the femoral failure rate is low and the long‐term success rate is high.
