【摘要】 目的通过对膝关节前交叉韧带后外束股骨止点的解剖测量,找到确定前交叉韧带后外束股骨止点的简单可行的方法,为双束重建前交叉韧带手术中的骨道定位提供理论依据。方法解剖20例新鲜膝关节标本(25～45岁)。在屈膝90°位,测量前交叉韧带后外束股骨止点中心点距股骨髁间窝外侧壁前方、后方和下方软骨缘的距离,再对测量数据进行评估和对比。结果前交叉韧带后外束股骨止点中心点距离股骨前方软骨缘(8.74±1.39)mm,距离后方软骨缘(8.69±1.57)mm(P=0.926)。后外束止点中心点距离股骨下方软骨缘(5.06±0.77)mm。结论膝关节屈膝90°位时,前交叉韧带后外束的股骨止点中心点位于股骨髁间窝外侧壁,距离下方软骨缘5mm,距离前方和后方软骨缘的距离相等。在前交叉韧带双束重建的手术中,应用本研究的结果能够简单、快捷地确定前交叉韧带后外束股骨骨道位置。更多还原

【Abstract】 Objective By measuring the posterolateral bundle(PLB) femoral attachment,to find a simple guideline for precisely localizing the PLB femoral bone tunnel during the double-bundle anterior cruciate ligament(ACL) reconstruction.Methods Twenty cadaveric knees,aged 25 to 45 years,were dissected.With the knees flexed at 90°,the measurement of the distances from the center of the PLB femoral attachment to the anterior border and to the posterior border of the articuar cartilage of the lateral wall of the intercondylar notch was made.The collected data were evaluated and compared.Results With the knees flexed at 90°,the center of the PLB was located at(8.74±1.39)mm and(8.69±1.57)mm from the anterior and the posterior cartilage borders of the lateral wall of the intercondylar notch,respectively(P=0.926).The distance between the center of the PLB attachment to the low cartilage border of the lateral intercondylar wall was(5.06±0.77)mm.Conclusion The findings in this study suggest that the position of the center of the PLB femoral insertion is at the middle of the line joining the anterior and the posterior borders of the femoral cartilage.It is a simple,easy and repeatable way to use our results as a guideline and the PLB attachment remnant as a reference at the same time to locate the femoral PLB tunnel.更多还原
