Pelvic bone adaptation around the acetabular component (cup) after cementless total hip arthroplasty was evaluated using quantitative computed tomography technique. Acetabular cancellous bone around the cup decreased as much as -36% at one year after operation. On the other hand, the decrease was moderate betweenone-year and two-year evaluation. In contrast, there was tiny bone density change in the cortical bone. We observed neither osteolytic lesion nor loosening of the cup at two years after operation. The changes of load transfer pattern may affect the remodeling of pelvic bone around the cup after total hip arthroplasty.

应用定量CT技术评价非骨水泥型全髋关节置换术后髋臼假体周围骨盆骨的适合性。术后一年，髋臼周围松质骨减少达-36%。另一方面，在一年和两年的评估之间，减少是适度的。相比之下，皮质骨中有微小的骨密度变化。术后两年未见溶骨性病变，也未见管杯松动。负荷传递模式的改变可能影响全髋关节置换术后盆腔周围骨盆骨的改建。
