摘　　要：目的 :通过外翻 (HV)和正常足部的X线测量分析 ,探讨外翻的发病机制及临床意义。方法 :对 118例正常人中 12 1足和 5 1例HV病人中 5 6足的外翻角 (HVA)、1～ 2跖骨间角、1～ 5跖骨间角和第 1跖骨长度与趾长度之比率进行测量 ,将测量数据进行统计学处理。结果 :正常足和HV病人测量结果分别为 :HVA 11.32°± 7.11°和 2 7.31°±6 0 3°,1～ 2跖骨间角 7.5 0°± 3.2 1°和 10 .2 1°± 3.5 6° ,1～ 5跖骨间角 2 1.80°± 7.6 0°和 2 7.92°± 9.80°,第 1跖骨长度与趾长度比值 1.13± 0 .0 9和 1.16± 0 .13。正常足男、女之间各种角度无统计学差异 (P >0 .0 5 ) ,正常足与HV病人的HVA、1～ 2和 1～ 5跖骨间角均有显著性差异 (P <0 .0 0 0 5 ) ,第 1跖骨长度与趾长度比值无差异 (P >0 .0 5 )。结论 :HV病人的首要X线表现为HVA增大 ,1～ 5跖骨间角增大是发生HV的主要基础 ,1～ 2跖骨间角增大是继发改变。HVA >2 0°,1～ 2跖骨间角 >10°是诊断和治疗HV的重要客观指标。Objective:To evaluate the pathogenesis and clinical significance of hallux valgus (HV) by the X-ray measure meat analysis of HV and normal feet.Methods:The hallux valgus angle(HVA)?the angle between first and second metatarsal?the angle between first and fifth metatarsal?and the rate between first metatarsal and hallux length were measured in 121 feet of 118 normal persons and 56 feet of 51 HV patients.The measured data were managed by statistics.Results:The angle between first and second metatarsal are respectively 7.5°±3.21°and 10.2°±3.56°,The angle between first and fifth metatarsal are 21.80°±7.60°and 27.92°±9.80°,HVA are 11.32°±7.11°and 27.31°±6.03°,The rate between first metatarsal and hallux length are 1.13±0.09 and 1.16±0.13 in normal feet and patients.There are not different on every angle between normal man and female( P >0.05);There are statistically different on the every measured value between normal foot and HV patients( P <0.0005).There is no statistically different in the rate between first metatarsal and hallux length( P >0.05).Conclusion:The imporslant X-ray finding is enlargement of HVA in HV patients.The enlargement of the angle between first and fifth metatarsal is led to basis of HV.The enlargement of the angle between first and second metatarsal is secondary alteration.The HVA>20°,the angle between first and second metatarsal>10°is the important objective standard of diagnosing and treating HV.
