목적: 대퇴 전자부 주위 골절 치료의 근위 대퇴 골수정의 치료 결과를 압박 고 나사와 비교하여 분석하고자 한다. 대상 및 방법: 2003년 1월부터 2004년 12월까지 전자부 주위 골절 환자 중 근위 대퇴 골수정으로 치료 받고 최소 12개월 이 상 추시 경과 관찰이 가능하였던 33명의 환자(I 군)를 후향적으로 분석하였다. 압박 고 나사를 이용하여 수술 받은 34명의 환자 (II 군)를 대조군으로 하였다. 두 군의 수술 시간, 출혈량, 수혈량, 중환자실 이용 빈도, 배액량, 재원 일수, 합병증의 빈도, 대퇴경 간 각, 지연 나사의 이동 거리, 골유합, Jesen의 function score와 Parker와 Palmer의 mobility score 차이를 비교하였다. 결과: 수술 시간은 I 군에서 105분, II 군에서 157분이었고 예상 출혈량은 540 cc, 840 cc이었다. 수혈량은 각각 1.5 pints와 2.2pints이었고 중환자실 전실 빈도는 각각 6%와 30%이었다. 배액량은 36 cc와 203 cc이었으며 재원일 수는 25일과 33일 이었고, 합병증은 15%, 17%이었다. 이 중 고정 실패에 따른 재수술의 경우는 I 군에서만 2예(6%) 있었다. 골유합은 17.5주와 18.9주이었으며 대퇴경간 각은 각각 3.70도, 3.87도이었다. 지연 나사의 평균 이동 거리는 1.9 mm, 6.9 mm이었으며 function score는 각각 1.81과 1.94이었으며, mobility score는 각각 6.51, 6.16이었다. 수술 시간, 예상 출혈량, 수혈량, 중환자실 전실 빈도, 배액량, 재원 일수, 골유합, 지연 나사의 평균 이동 거리에서 통계학적 의의가 있었으며(p<0.05) 그 외 모든 결과에서는 통계학적인 의의가 없었다(p>0.05). 결론: 대퇴 근위 전자부 주위 골절의 치료에 있어서 근위 대퇴 골수정을 이용한 술식은 압박 고 나사에 비하여 양호한 임상적 결 과가 관찰되었다.
Abstract
Purpose: This study compared the results between PFN (Proximal Femoral Nail) and DHS (Dynamic Hip Screw) in the treatment of a peritrochanteric fracture of the proximal femur. Materials and Methods: 33 patients with peritrochanteric fractures treated with PFN for a minimum follow-up of at least 12 months were analyzed retrospectively. The patients with PFN group (n=33, group I) were taken from operations between Jan. 2003 and Dec. 2004, and the DHS group (n=34, group II) were used as the control group. Both groups were compared with regard to the operation time, blood loss, transfusion, ICU care, drain amount, duration of admission, complications, the neck shaft angle, the sliding length of lag screws, radiological union, and the functional recovery grade using Jensen and Palmar and Parker’s method. Results: The mean operative times were 105 (group I) and 157 minutes (group II), blood losses were 540 and 840cc, transfusion volumes were 1.5 and 2.2 pints, ICU care was 6 and 30%, drain amounts were 36 and 203 cc, admission duration was 25 and 33 days, complications were 15 and 17%, reoperations by the failure of the reduction were 2 cases(6%) (group I) and 0 (group II), difference in the neck shaft angles were 3.70 and 3.87ခ, sliding length of the lag screws were 1.9 and 6.9 mm, radiological union was achieved in 17.5 and 18.9 weeks, function scores were 1.81 and 1.94, and the mobility scores were 6.51 and 6.16, respectively. These results show that there were advantages of PFN in terms of the operative times, blood loss, transfusion, ICU care, drain amounts, admission duration, sliding length of the lag screws and radiological union with statistical significance (p<0.05). Conclusion: Good clinical results can be achieved with PFN compared with the DHS for the treatment of peritrochanteric fractures of the proximal femur.
