观察和統計了430例中国成人坐骨神經和梨状肌位置关系的类型,最常見的是坐骨神經以一总干經梨状肌下緣出盆的常見型,占60.5±2.36%。其它各型非常見型共占39.5±2.36%,其中以腓总神經穿梨状肌,胫神經經梨状肌下緣出盆者为多,占29.5±2.20%。統計結果进一步証明了坐骨神經出盆形态具有显著的人种間差异,即中国人和日本人的非常見型出現率較欧美人高。坐骨神經与梨状肌位置关系各型式,在男女性之間和左右側之間都没有显著差异,双側同型的(对称)占大多数(73.5±3.01%)。用本文材料与国內其它作者的材料綜合比較,也看不出主要非常見型(Ⅱ型)的出現率在年龄上有明显差异。本文承潘銘紫教授热心指导,何光箎教授审阅,并承张为龙同志供給部分文献,赵克勤同志协助收集部分标本,特此一并致謝。
The types of positional relationship between the sciatic nerve and the piriformis in 430 Chinese adults were observed and counted. The most common type was the common type of the sciatic nerve with a total dryness of 60.5 ± 2.36%. Other types of non-common type accounted for a total of 39.5 ± 2.36%, of which the common peroneal nerve through the piriformis, tibial nerve by the bottom of the piriformis out more basin, accounting for 29.5 ± 2.20%. The statistical results further prove that there is a significant inter-ethnic difference in the morphology of the sciatic nerve out of the basin. That is to say, the unusual occurrence rate of Chinese and Japanese is higher than those in Europe and the United States. There was no significant difference between men and women and between the right and left sides in the types of positional relationship between the sciatic nerve and the piriformis. The majority of bilateral isoforms (73.5 ± 3.01%) were symmetrical. With this material and other domestic materials comprehensive comparisons, but also do not see the major non-common type (type II) the incidence of significant differences in age.
