Since the use of the Charnley hip prosthesis, the component loosening has been the most cause of failure. The roentgenographic appearance of the bone cement junction in total hip arthroplasties has recevied frequent attention. The incidence of loosening as a mode of clinical failure is consistently much lower than the incidence of radiolucent lines. One study shows aseptic loosening of the acetabulum component necessitating revision occurred in 6 percent of all 322 acetabular component, while 2 percent of all 322 femoral component. The present investigation was an attempt to compare observations on plain radiographs with those made during the exchange operation in a series of total hip arthroplasties revised for various reasons. In a series of 29 patients, 30 cases who have admitted for revision at Seoul Paik Hospital from March 1992 to March 1994 by late loosening after being performed cemented total hip athropasty were studies about the radiographic analysis, correlation of the real and radiographic measurement of cement and bone contact. The Result as follows; 1. The mean age at revision was 56 years old and the average time to revision was 12.3 years.

고관절 전치환술 후 비감염성 해리는 가장 흔한 실패의 원인으로 보고되고 있으며 특히 비구컵의 해리는 10년 이후 급속히 진행되는 양상을 보여 해결책에 관심이 모아지고 있다. 저자들은 술후 10년 이후에 발생한 비구측의 후기 해리로 재대치술을 시행받은 환자 20명의 임상적, 방사선학적 측정과 현미경적 특징을 살펴봄으로써 후기 해리와 비구컵 마모의 연관성을 알아 보았다. Since the use of the charnley hip prosthesis, aseptic loosening of the component has been the most common causes of failure. Especially, loosening of acetabular cup has been progressed rapidly after 10 years postoperatively. So, the cause and resolution of late loosening of acetabular cup has been the topic. The 20 patients who have admitted for revision at Seoul Paik Hospital from Sept. 1992 to 1993 by late loosening (more than 10 years after postoperatively) of acetabular cup after being performed Charnley Low Friction arthroplasty were studied about the clinical and radiographic analysis, correlation of the real and radiographic measurement of wear and microscopic examination of the acetabular cup obtained by revision. The results were as follows : 1.The average time to revision was 13.2 years and showed unsatisfactory clinical results. 2.Acetabular loosening was found in 14 cases and all of them was involved all three zones and the most common site was zone III. 3.The average wear of polyethylene cup measured from radiographs by charnley and cupic(1973) was 2.60mm the real wear by Wroblewski(1985) was 2.73mm, and the average wear rate was 0.26mm year. 4.There was a significant correlation between radiological and real wear on measurement. 5.Cup wear was checked by SEM and showed abrasion, crack and delamination. 6.Granulation tissue was observed in all cases and polyethylene wear particle was found by microscope. 7.Mechanical and biological that reaction has been contributed to late loosening of acetabular cup, and afterwards invention of instrument to minimize biological reaction will be needed to prolong survivalship.
