摘要
目的探讨应用MRI测量国人半月板正常量值范围,为诊断半月板疾病和半月板移植提供客观依据。材料和方法采用四肢专用关节MRI成像系统,对57只膝关节正常半月板的前角、体部和后角进行高度和宽度的测量,还对胫骨平台的宽度进行测量。结果内侧半月板前角、体部、后角的宽度和高度分别为7.74±1.41mm和4.48±0.77mm,8.43±1.91mm和4.49±0.72mm,10.89±2.22mm和5.50±1.01mm。外侧半月板前角、体部、后角的宽度和高度分别为8.96±2.06mm和4.28±0.70mm,9.18±2.12mm和4.74±0.90mm,9.64±2.26mm和5.56±0.86mm。外侧半月板体部宽度与胫骨平台宽度比例为13.97%。结论本研究所获国人体内MRI测量的正常数据,对诊断半月板疾病和半月板移植有重要参考价值。
Purpose:The aim of this study was to investigate the dimensions of normal meniscus with MRI,which can supply objective data for diagnosis of various meniscal diseases and meniscal replacement.Materials and Methods:Fifty-seven normal knee joints were investigated.The height and width of the anterior,mid-body and posterior horn of medial and lateral menisci were measured on a dedicated MRI for limbs.The width of tibial plateau was also measured.Results:For the medial meniscus,the height and width of the anterior horn were7.74±1.41mm and4.48±0.77mm,the height and width of the mid-body were8.43±1.91mm and4.49±0.72mm,and the height and width of posterior were10.89±2.22mm and5.50±1.01mm,respectively.For the lateral meniscus,the height and width of the anterior horn were8.96±2.06mm and4.28±0.70mm,the height and width of the mid-body were9.18±2.12mm and4.74±0.90mm,the height and width of posterior were9.64±2.26mm and5.56±0.86mm,respectively.The ratio of normal lateral meniscus to the tibia plateau was13.97%.Conclusion:The measurement data of Chinese normal knee joint obtained in this study are of important reference value in the diagnosis of meniscus of the knee joint and meniscal replacement.
