Abstract

Purpose: We wanted to compare the insufficiency stress fractures of the femoral neck (group I) with the traumatic femoral neck fractures (group II) in patients who were 70 years of age and older. Materials and Methods: Between January 2000 and October 2006, we evaluated 10 insufficiency stress fractures among 191 femoral neck fractures in patients who were 70 years of age and older. We compared these fractures with the traumatic femoral neck fractures by using the bone mineral density (BMD), neck-shaft angle, the hip axis length (HAL) and the ratio of the HAL to the femoral neck width. Results: The incidence of insufficiency stress fracture was 5.2%. There were 6 cases of displaced fractures and 4 cases of non-displaced fractures. All of non-displaced fractures revealed the tension (transverse) type. The mean neck-shaft angle was 130.45 degrees in group I and this was 131.94 degrees in group II. The mean HAL was 117.6 mm in group I and 115.3 mm in group II, and the ratio of the HAL to the femoral neck width was 0.30 in each group. The BMD (T-score) was -3.73 in group I and -3.4 in group II. Conclusion: The BMD of the insufficiency fracture group was significantly lower than that of the traumatic femoral neck fracture group. However, there were no significant differences in the neck-shaft angle, the HAL and the ratio of the HAL to femoral the neck width between the 2 groups.

목적: 70세 이상 노인에서 발생한 대퇴골 경부의 부전성 피로 골절(제 1 군)을 분석하여 외상성 대퇴골 경부 골절(제 2 군)과 비교하고자 하였다. 대상 및 방법: 2000년 1월부터 2006년 10월까지 70세 이상 노년에서 발생한 191예의 대퇴골 경부 골절 중 10예의 부전성 피로골절에 대하여 분석하였으며, 외상성 대퇴골 경부 골절과의 차이점을 골밀도, 고관절장축길이, 대퇴경간각 및 고관절장축길이 대 대퇴경나비의 비율을 이용하여 분석하였다. 결과: 대퇴골 경부 부전성 피로골절의 발생율은 5.2%이었다. 10예 중 단순 방사선 검사상 전위성 골절이 6예, 비전위 골절은 4예였다. 비전위골절은 모두 신장형(횡형)이었다. 경간각은 제 1 군에서 130.45도, 제 2 군에서 131.94도였으며, 고관절장축길이는 제 1 군에서 117.6 mm, 제 2 군에서 115.3 mm였고, 고관절장축길이와 대퇴경나비의 비율은 두 군에서 모두 0.30이었다. 골밀도는 제 1군에서 T-점수가 -3.73, 대조군에서는 -3.4였다. 결론: 외상성 대퇴골 경부 골절군과의 비교에서 골밀도는 부전성 골절군에서 의미 있게 더 낮았으나 단순 방사선학적 계측상 경간각, 고관절장축길이 및 고관절장축길이와 대퇴경나비의 비율에서 유의한 차이는 없었다.䄠돀⨀堘�⨀ၡ⨀ᤠ돐ࢷ�⨀ࢷ�⨀㡡⨀덐䡡⨀Ȁ셓ᄀ䭇
