目的 探讨前交叉韧带股骨等距点的个体差异. 方法对100名健康受试者的膝关节侧位片在PX电子系统下找到股骨等距点(i点),测量i点到髁间窝后缘过顶点(OT)距离,先用2×2析因分析探讨四组年龄段(20～30岁、30～40岁、40～50岁、>50岁)中年龄、性别因素对测量结果的影响,再用SNK-q统计学方法对这四组年龄段进行组间对比.结果 i点至髁间窝后缘过顶点距离为7.5～15.1 mm,平均(10.5±1.4)mm.不同年龄组间i点至OT点距离差异有统计学意义(F=2.843,P=0.042),不同性别间两点距离差异也有统计学意义(F=4.245,P=0.042),而年龄与性别这两因素之间无明显交互效应(F=0.456,P=0.714).20～30岁组与>50岁组、40～50岁组差异有统计学意义,30～40岁与20～30岁组之间差异无统计学意义,30～40岁、40～50岁、>50岁组这三组之间两两比较差异无统计学意义(P>0.05).结论 等距点的测定应有个体差异,术前X线片测量及术中双监视法有助于准确定位等距点.

Objective To investigate individual variations of the femoral isometric poiIit of anterrior cruciate ligament(ACL). Methods The femoral isometric points(i)were determined by measuring the knee joint lateral projections in 100 adults.The distances from the femoral isometric point i to the posterior border of intercondylar notch were measured and compared among 4 age groups(20 to 30 y,30 to 40 y,40 to 50 y and>50 y)by 2 × 2 factor analysis and Student-Newman-Keuls (SNK-q)Analysis to determine the effects of age and gender on the measurements. Results The average distance was(10.6±1.55)mm,ranging from 15.05 am to 7.50 mm.The 2×2 factor analysis showed the differences were signifcant between age groups(F=2.843,P=0.042)and between sexes(F=4.245,P=0.042).but the age and sex factors were not interacted (F=0.456,P=0.7 14). The SNK-q Analysis revealed the differences were significant between the 20 to 30 y group and the 40 to 50 y group as well as the>50 y group(P<0.05),but not significant between the 30 to 40 y group and the 20 to 30 y group(P>0.05).No signifieant difference was observed between any two of the 30 to 40 y group,40 to 50 y group and>50 y group(P>0.05). Conclusion Since the ACL femoral isometric points vary from person to person,it is valuable to check them twice radiologically before and during the operation.
