韧带松弛指数测量

Determination of the Index of Ligamentous Laxi-ty

作者采用Ｃｏｏｐｅｒ方法测量５１５例（１０３０腕）韧带松弛指数。结果显示，左腕韧带松弛指数为７１．２１±２３．７０ｍｍ，右腕为７４．０５±２３．６３ｍｍ。本组研究提示：（１）韧带松弛指数个体差异很大（０～１２５ｍｍ）；（２）右腕（优势侧）韧带松弛指数略大于左腕（Ｐ＜０．０５），但同一年龄组左、右腕韧带松弛指数则无差异（Ｐ＞０．０５）；（３）男性韧带松弛指数大于女性（Ｐ＜０．００１）；（４）随着年龄的增加韧带松弛指数也随之增大，分别以２０～３０岁和５０～６０岁间增大显著（Ｐ＜０．０１），但性别差异相对缩小（Ｐ＞０．０５）。

Abstract The index of ligamentous laxity in 1030 wrists of515 persons were measured with the method of Cooper,With the wrist maximally flexed and the thumbmaximally abducted,the index of ligamentous laxity isdefined as the shortest distance in centimeters from thetip of the thumb to the volar surface of the forearm. As the amount of laxity increases,the index decreas-es. The results showed that the index on the left wristwas 71.21±23.70,and on the right, 74.05±23.63. The authors conclude:(1)the individual difference ofthe index was remarkable ranged frorn 0 to 125 mm;(2 )the index was slightly larger on the right wrist(the dominant hand) ( P<0. 05 ),but no differencewas seen among the different age groups(P> 0.05);(3 )the index was larger in man than in woman(P<0.001);(4)the index increased with age and this wasextremely evident in the age ranges of 20～30 and 50～60 (P<0.01 ),however,no difference was seen inbetween the two sexes(P>0,05).
