简易体表胸廓测量法在直背综合征诊断中的应用:与X线法的相关性研究

A Simple Method for Chest Measurement Used in Diagnosis of Straight Back Syndrome:Correlation with Roentgenometry

目的 本研究旨在探讨应用一种简易体表胸廓测量法代替Ｘ线法诊断直背综合征的可行性。方法 对３２ 例直背综合征者，采用骨盆测量器经体表测量胸廓前后径（ＡＰＤｂ） 、胸廓横径（ＴＴＤｂ） 及其比值（ＡＰＤｂ／ＴＴＤｂ），并与Ｘ线相应测值进行相关与回归分析。结果 ＡＰＤｂ 与ＴＴＤｂ 分别与Ｘ 线测值正相关（ｒ ＝ ０－７７，０－７８；Ｐ＜０－００１），ＡＰＤｂ／ＴＴＤｂ 与Ｘ 线测值ＡＰＤｘ／ＴＴＤｘ 呈正相关（ｒ＝ ０－７７ ，Ｐ＜ ０－００１），其直线回归方程为ＡＰＤｂ／ＴＴＤｂ ＝０－２５ ＋０－９８（ＡＰＤｘ／ＴＴＤｘ）。结论 简易体表胸廓测量法与Ｘ 线法的测值有较好的相关性，可为直背综合征的诊断提供一种简捷经济的新方法。

Purpose The purpose of this study is to determine the usefulness of a simple method for chest measurement used in diagnosis of straight back syndrome (SBS).Methods Thirty two patients with SBS diagnosised by physical and chest radiographic findings were evaluated.On body suface,antero posterior diameter (APDb) of the thorax,transthoracic diameter (TTDb),and APDb/TTDb ratio were measured by pelicometer and were compared with parameters mea sured on X ray chest films.Results APDb and TTDb correlated with X ray parameters APDx and TTDx respectively ( r=0.77,0.78;P<0.001). APDb/TTDb correlated with APDx/TTDx( r=0.77,P<0.001; APDb/TTDb=0.25+0.98 APDx/TTDx).Conclusion Chest measurement on body suface was significant correlation with roentgenoscopy and may act as a simple,economical method for diagnosis of SBS.
