摘要: We determined the effect of pre-operative bone structure upon temporal effects remodeling after total hip arthroplasty (THA) in a series uncemented implants. evaluated 345 patients (375 hips), who had either Dorr Type-A (238 hips) or Type-B (137 bone, and received proximally-coated cementless THA were followed for mean 6 years. Outcomes included aseptic survivorship, Harris scores, radiographic evaluation patterns remodeling. The survivorship (97.5% vs. 98%) final scores (92 94 points) similar between Types-A -B respectively. Bone was seen significantly earlier over longer duration bone. At 5-years, periprosthetic condensation (78% 54%) cortical hypertrophy (53% 37%) higher radiolucencies at any zone lower compared to There increased men women. Various differences may not negatively impact clinical outcome mid-term follow-up. Morphologic type appears be predictive physiologic response loading.
