目的本文通过分析尸体标本和活体MRI影像前交叉韧带(ACL)解剖学测量,找出ACL胫骨、股骨止点相关数据,与矢状面、冠状面、胫骨关节面夹角,对比分析两者差异,为手术方案及手术效果提供相应依据。方法通过解剖15个膝关节标本和对120例行膝关节MRI扫描。结果尸体标本和活体MRI上ACL胫骨止点中心距胫骨平台前缘距离分别为:(12.3±1.2)mm,(11.9±1.9)mm,两者差异有统计学意义(P<0.05)。结论 MRI可以测量ACL相关解剖数据,一定程度上可替代尸体标本的实际测量,能同时进行较大样本量的测量,本研究所得相关数据可以为手术提供定位依据,并能客观评价骨道及韧带位置优劣,提高手术效果。
OBJECTIVE: To analyze the anterior cruciate ligament (ACL) anatomical measurement of cadaveric specimens and live MRI images to find out the data of ACL tibia and femoral buttress, and the angle between them with the sagittal, coronal and tibial articular surfaces. , To provide the appropriate basis for the surgical program and surgical results. Methods Fifteen knee specimens were dissected and MRI scan of 120 knees were performed. Results The distances between the dead center of ACL tibia and the front of the tibial plateau on the postoperative MRI were (12.3 ± 1.2) mm and (11.9 ± 1.9) mm, respectively. There was a significant difference between the two groups (P <0.05). Conclusion MRI can measure ACL-related anatomical data, to a certain extent, it can replace the actual measurement of the corpse specimens and can simultaneously carry out a large sample size measurement. The data obtained in this study can provide the basis for the operation and can objectively evaluate the bone and ligaments Location advantages and disadvantages, improve surgical results.
