本文观察了中国成人的半月板300例,并对其中的160例(男100例、女60例)进行了测量。外侧半月板以侧分宽度占半月板全宽的1/3—1/2者为最多(48％),超过全党1/2的占17％,盘型占3.67％。内侧半月板以后分宽度占半月板全长的 1/3—2/5者为最多(59.33％)。将内侧半月板的开口按大小分成三型,以中间型为最多(48.71％)。膝横韧带的出现率为55.33％,半月板股骨韧带的出现率为98.67％。从肉眼观察的各项中未发现男女性之间和左右侧之间有明显差别。从许多方面测量了内侧和外侧半月板。从各项测量的数值中,可见男性的数值都比女性的大,但各项中男女间的比值都在0.80—0.93之间,因此男女半月板之间只有大小的差别,不存在各部分比例上的差异。中国人与日本人之间半月板的各项数值极相近,只是日本人的内侧半月板较中国人的厚,腘肌沟较宽。中国人与欧美人之间半月板的形态差异是:中国人的外侧半月板侧分较宽,矢状径较长;膝横韧带及半月板股骨韧带的出现率较高;内侧半月板后分较宽,开口较大,腘肌沟较宽。本文试图从形态上探讨了中国人与欧美人在内、外侧半月板损伤中所出现的不同出现率。
In this paper, we observed 300 cases of meniscus in Chinese adults and measured 160 of them (100 males and 60 females). Lateral meniscus to the lateral width of the width of the meniscus 1 / 3-1 / 2 were the largest (48%), accounting for more than 1/2 of the whole party accounted for 17% of the disk accounted for 3.67%. The medial meniscus after the width of the total length of the meniscus 1 / 3-2 / 5 were the most (59.33%). The medial meniscus openings by size divided into three types, with the largest type (48.71%). The incidence of transverse ligament of the knee was 55.33%, and the incidence of the medial femoral ligament was 98.67%. No significant differences between men and women and between right and left sides were found in the various items visually observed. The medial and lateral menisci were measured in many ways. From the measured values, we can see the value of men than women are large, but the ratio between men and women in the 0.80-0.93 between men and women therefore only the size difference between the meniscus there is no proportion of each part The difference. The values of the meniscus between Chinese and Japanese are very similar, except that the medial meniscus of Japanese is thicker than that of Chinese, and the flesh muscle is wider. The morphological differences of the meniscus between Chinese and Europeans and Americans are as follows: the lateral lateral meniscus of the Chinese is wider and the sagittal diameter is longer; the incidence of the transverse ligament of the knee and the femoral ligament of the meniscus is higher; and the medial meniscus posterior Wider, larger opening, wider loin muscle ditch. This article attempts to explore the different appearances of the medial and lateral meniscus injuries between Chinese and Europeans and Americans.
