掌指骨的X线测量及相互间数学比例关系的临床应用研究

目的　对掌、指骨进行X线测量 ,为临床诊断及手外科提供可靠的解剖学数据和资料 ,同时提供掌骨长、指骨长之间的数学比例关系式 ,对手外科掌指骨长度的确定和假体的设计提供参考依据。方法　随机选择健康汉族大学生 186人 (男 90人 ,女 96人 ) ,进行双手后前位X线拍片 ,分别测量各掌骨与指骨长 ,将所得数据应用SPSS软件进行统计学分析。结果　得出各掌骨长、各节指骨长的比例关系 ,其中一 /二、二 /四、二 /五、三 /四掌骨长比值 ,拇指 /示指、拇指 /环指、示指 /小指近节指骨长比 ,示指 /小指、中指 /小指、环指 /小指中节指骨长比 ,拇指 /示指、拇指 /中指远节指骨长比值性别差异均有显著性意义。结论　以上比例关系式在手矫形外科中对各种原因引起的手骨缺陷进行理想的掌长及指长选择 ,从而为假体设计提供帮助

The Study of Clinical Application on X-ray Measurement of Metacarpal and Phalanges Bones and Their Mathematical Relations

Objective To provide credible anatomic data and information for clinical diagnosis and surgery of hand by measuring the length of metacarpal bone and phalanges of hands on X-ray films and to study their mathematical relations.Methods The X-ray films of hands on posteroanterior position were taken in 186 healthy college students (M90,F96).The length of each metacarpal and phalange were measured.All the data were calculated by SPSS software.Results The mathematical relations of each metacarpal and phalange bone were obtained .It was found that there were sexual differences in the ratio of first to second,second to fourth,second to fifth and third to fourth metacarpal length,the ratio of first to second,first to fourth and second to fifth proximal phalangeal length,the ratio of second to fifth,third to fifth and fourth to fifth middle phalangeal length and the ratio of first to second and first to third distal phalangeal length.Conclusion The results of this mathematical relations are of great significant in orthopaedic surgery of hand.
