Short-Term Aseptic Loosening of the Femoral Component in Canine Total Hip Replacement: Effects of Cementing Technique on Cement Mantle Grade

Objectives— To evaluate the effects of different cementing techniques on radiographic cement mantle grade and short-term aseptic loosening of the femoral component in canine total hip replacement (THR). Study Design— Retrospective study. Sample Population— Radiographs of 284 dogs that had THR. Methods— Immediate postoperative radiographs of 284 dogs that had cemented THR were reviewed by 4 surgeons and 1 radiologist and assigned a cement mantle grade using a 4-grade classification system. Dog age and weight at surgery, cementing technique (1st, 2nd, 3rd generation), complications (type and timing), and follow-up time were retrieved and analyzed. Results— Mean cement mantle score for 2nd generation technique was significantly higher than 3rd generation technique and both were significantly higher than 1st generation technique (P
