영문 초록

Purpose : During the follow- up test of resurfacing hip joint arthroplasty patients, the lateral screening test is usually taken to distinguish wear, tear, debris, or osteolysis, when the boundaries of the bone and the implant are described as a single line. So far, however, there is no reported radiologic data about effective test method for accurate information processing and image description, so far. Therefore, we comparatively analyzed the effectiveness of methods by measuring time of lateral screening test useful for diagnosis and temporizing translateral test. Matherials and Methods : 200 follow-up patients (152 men, 48 women) of resurfacing hip joint arthroplasty, who had visited our hospital from April 2009 to January 2010 were subjected for this study, and their average age was 44.9 years (20~78 years old). ① 12 university hospitals including us were subjected for the survey of whether the resurfacing hip joint arthroplasty was held or not, and about the lateral test method. ② We classified and measured the femur angle at the hip AP(Internal rotation 15°) position into 5 groups (A:120°~125°, B:125°~130°, C:130°~135°, D:135°~140°, E:140°~145°) by PACS and analyzed the distribution. We also classified the incident beam into 4 groups (Cranial 30°, 35°, 40°, 45°), tested the effective incident beam(Tube angle) for diagnosis by femur angle, asked for screening by faculties, residents, and radiologists of the department of radiology and orthopedics, and finally analyzed statistically by Chi- square verification. ③ We comparatively analyzed the diagnostic effectiveness and work efficiency of temporizing translateral test with the published experimental method, during the lateral test for resurfacing hip joint arthroplasty patients. Results : ① 5 of 12 university hospitals provided resurfacing hip joint arthroplasty treatment, while only our hospital was proved to conduct an independent test method. ② The result of Chi-square test(P-Value=0.001) showed the maximal femur angle distribution at 125°~140°, and the most useful image for diagnosis was obtained from the result of 129 of 200 patients showing the incident beam(Tube angle) at Cranial 35°~40°. ③ Both groin lateral test and translateral test provided useful images for diagnosis. But, the groin lateral test method could improve the problems of translateral test method about the reproducibility of incident beam and the low repeat rate of measurement. Also, the efficiency of test was much higher by reducing average measurement time for more than 2 times (40.85 sec vs 82.85 sec). Conclusion : From this study subjecting the follow-up patients of resurfacing hip joint arthroplasty, the result of lateral screening test showed the best image with the incident angle by Cranial 35°~40° to find out wear, tear, debris, or osteolysis between the bone and the implant. In addition, the time also reduced by more than 2 times compared to the temporizing method.
