The aim of this study is to find basic quantitative geometric data that may contribute to the understanding of the etiology of hallux valgus. Embalmed specimens with existing hallux valgus (N = 39) were dissected; 28 variables were measured with a Vernier caliper gauge and toe goniometer. Correlations between pairs of independent variables were calculated. Linear dependency of the hallux angle, varus angle, and the width of the forefoot on a number of independent variables was analyzed by multiple linear regression. A least squares method and a stepwise procedure were used. The distance from the tendon of the flexor hallucis longus muscle to the head of the first metatarsal bone explains more than other variables the variation in hallux angle and width of the forefoot. A widened forefoot is significantly correlated with both hallux and varus angles. The interrelation of the predictor parameters illustrates the complicated hallux valgus phenomenon.
本研究的目的是寻找可能有助于理解拇外翻病因的基本定量几何数据。对存在拇外翻的防腐标本（N = 39）进行解剖；用游标卡尺和趾关节角度测量仪测量28个变量。计算成对自变量之间的相关性。通过多元线性回归分析拇趾角、内翻角和前足宽度对多个自变量的线性依赖性。使用最小二乘法和逐步程序。拇长屈肌腱到第一跖骨头的距离比其他变量更能解释拇趾角和前足宽度的变化。前足变宽与拇趾角和内翻角均显著相关。预测参数之间的相互关系说明了复杂的拇外翻现象。
