摘　　要：目的通过X线测量分析，讨论拇外翻的发生及进行因素。方法根据是否存在拇外翻症状，将241例调查对象分为普通组和拇外翻组，渊查对象均为女性，年龄为10～90岁，均拍摄足部负重正位X线片，测量拇外翻角、1，2跖骨间夹角、籽骨偏移度，将上述3个测量值进行非配对的t检验分析，并与年龄进行Pearson相关分析。结果在普通组中，1，2趾骨间角与年龄呈正相关（相关系数r=0．125，P=0．003）。两组的籽骨偏移度均表现为与年龄呈正相关（普通组r=0．384，P〈0．0001，拇外翻组r=0．359，P=0．0002）。但是，拇外翻角和年龄没有关系（普通组r=0．066，拇外翻组r=0．080）。拇外翻组中3个测量值都比普通组显著增大。结论年龄增加可能导致拇趾变形，但是拇外翻组与普通组的3个X线测量值之间差异有统计学意义，可以认为先天因素是影响拇外翻发生的主要原因。Objective Based on the radiographs to analyze the generic and the developing factors of hallux valgus. Methods Two hundred and forty-one cases were divided into two groups according to the symptoms suffered, which were normal group and hallux valgus group. All cases were female, aged l0 to 90 years old. The three parameters- the first intermetatarsal angle, sesamoid inclination angle and hallux valgus angle, were taken full weight- bearing radiographs, analyzed by non-paired t test and Pearson correlation analysis according to age. Results In normal group, the first intermetatarsal angle was correlated with age （correlation coefficient r = 0. 125, P = 0. 003 ）. Sesamoid inclination angles in both groups were correlated with age（ normal group r = 0. 384, P 〈 0. 001 ; hallux valgus group r = 0. 359, P = 0. 0002 ）. However, hallux valgus angle had no correlation with age （ normal group r = 0. 066, hallux valgus group r = 0. 080 ）. All 3 parameters in hallux valgus group were statistically larger than normal group. Conclusion Aging is a possible reason to cause the 1st metatarsophlangeal joint deformity, but larger parameters were found in valgus group, suggesting the major cause of hallux valgus is congenital factor rather than aging.
