목적: 광학적 항법장치와 전자기장 항법 장치를 이용하여 하지의 역학적 축을 측정하고 그 정확성을 비교하였다. 대상 및 방법: 슬관절 치환술 환자에서 Orthopilot과 AxiEM을 이용하여 술 전 역학적 축을 측정하였다. 골 모형을 이용하여 역학적 축을 측정하였고 이를 ORTHODOC으로 측정된 값과 비교하였다. 두 기기의 해부학적 등록 오류에 따른 역학적 축의 변화값을 비교하였다. 결과: 임상적으로 측정된 역학적 축은 AxiEM에서(10.25±5.10°) Orthopilot보다(9.02±5.18°) 더 내반을 보였다. 두 항법 장치간의 평균 역학적 축의 차이는 1.23°였고 동일 환자에서 측정된 값이 두 항법 장치간에 3°이상 차이가 있었던 경우는 15%였다. 골 모형의 실제 역학적 축은 내반 1.25±0.15°였고, Orthopilot은 1.10±0.64°, AxiEM은 l.78±0.79°를 보여 통계적으로 두 항법장치간의 차이는 없었으나 Orthopilot이 재현성이 더 높았다. 등록오류에 의한 역학적 축의 변화는 AxiEM에서 컸다. 결론: 실험적으로 두 항법 장치는 높은 정확도와 재현성을 보여주었으나 광학적 항법장치가 보다 더 재현성이 높았다. 임상적으로는 두 항법 장치간의 불일치를 경험할 수 있었다. Purpose: This study compared the accuracy of mechanical axis measurement between infrared optical and electromagnetic navigation. Materials and Methods: We compared the preoperative mechanical axes of 20 TKAs using both navigation systems. Experimentally, the mechanical axes of the synthetic bone model were compared and the true mechanical axis was determined using the ORTHODOC. Additionally, a surgeon intentionally registered incorrect landmarks and then measured the amount of mechanical axis change in the two navigation methods. Results: Clinically, AxiEM provided greater varus (10.25°±5.100) than Orthopilot (9.02°±5.18°). The mean mechanical axis difference was 1.23° and a difference greater than 3° in the same patient occurred in 15% of patients. For the synthetic bone, the true mechanical axis was varus 1.25°, OrthoPilot displayed varus 1.10°±0.64° and AxiEM varus 1.78°±0.79°. The mechanical axis differences were not significantly different, but OrthoPilot had more reproducibility. When anatomical landmarks were erroneously identified, AxiEM showed a greater change in the mechanical axis. Conclusion: Both navigation systems provided high mechanical axis accuracy and reproducibility under experimental conditions. Infrared optical navigation was more reproducible than electromagnetic navigation. In the clinical setting, there was a disparity of mechanical axis difference greater than 3° in 15% between the two navigation methods in the same patient.

목적: 골 관절염을 동반한 이형성 고관절에 시행한 변형된 Chiari 절골술의 결과를 알고자 하였다. 대상 및 방법: 원형(dome)의 절골술로 변형된 Chiari 절골술을 시행받은 이형성 고관절 환자 17명을 대상으로 하였으며, 평균 연령은 33.5세, 평균 추시기간은 28.2개월이었다. 임상적 평가는 절뚝거림, 고관절 운동범위와 Harris Hip Score (HHS)를 사용하였고 방사선학적 평가는 acetabular 각, Center edge 각, 비구피복, 체중부하 관절 간격, 최소 관절 간격 등을 평가하였다. 결과: 수술 전 동통 보행을 호소하던 13예 중 6예에서 호전되었고, 고관절 운동범위도 외전, 외회전, 내회전에서 의의 있게 향상 되었다. HHS 점수는 54.6점에서 81.6점으로 통계학적으로 의의를 보였다. 방사선학적 결과상 acetabular 각, Center edge 각, 비구피복은 각각 수술 전 47.5°, 9.9°, 57.9%에서 최종 추시상 40.0°, 38.5°, 82.4%로 의의있는 변화를 보였다. 결론: 변형된 Chiari 절골술은 조기 및 중기 골 관절염을 동반한 이형성 고관절의 치료에 있어서 임상적, 방사선학적으로 의의있는 효과를 보이는 적절한 방법 중의 하나이다. Purpose : To evaluate the clinical, radiographic results of a modified Chiari osteotomy for dysplastic hips associated with early osteoarthritis. Materials and Methods : 17 dysplastic hip patients were examined, and treated with modified Chiari osteotomy, which is dome-shaped pelvic osteotomy. Their mean age at surgery was 33.5 years old (range: 14-53 years), and the mean follow-up period was 28.2 months (range: 12-73 months). In the clinical evaluation, limping, range of motion and Harris Hip Score (HHS) were used and in the radiographic evaluation, center edge angle, acetabular angle, head coverage, weight bearing joint space and minimal joint space were evaluated. Results : Six out of 13 patients who had an antalgic gait improved, and the level of abduction, internal rotation and external rotation showed significant improvement at the final follow-up. The radiographic results showed that the acetabular angle improved significantly from 47.5° preoperatively to 40.0° at the last follow-up. The center edge angle showed significant improvement from 9.9° preoperatively to 38.5° at the last follow-up and the head coverage also showed significant improvement from 57.9% preoperatively to 82.4% at the last follow-up. Conclusion : A modified Chiari osteotomy is an effective method for a dysplastic hip with a mild and moderate grade of osteoarthritis, and shows improved clinical and radiographic results.

Deep vein thrombosis(DVT) after joint arthroplasty in the lower extremity has been one of the major causes of death in postoperative complications. But, there is little information on incidence and clinical risk factors of DVT in Korea. Fifty-eight patients (sixty-two cases) who underwent TKR were included in this study for evaluation of the incidence of DVT and correlation with clinical risk factors after total knee replacement(TKR) in Korea. Venography were performed preoperatively and postoperatively, and clinical risk factors were examined. The preoperative venography was performed within seven days before the surgery, and postoperative venography seven to 14 days after the surgery. There was no evidence of thrombosis in any patient preoperatively, but thrombi were observed in seven cases (11%) postoperatively. Six cases showed thrombi in the calf vein and one case showed thrombi in the femoral vein. There was no statistically significant difference in incidence rate of DVT according to clinical risk factors such as age, toumiquet time, BMI(body mass index), diastolic blood pressure, operation time and coagulation assay(platelet, PT, aPTT, Anti-thrombin III, fibrinogen).
