足底软组织厚度的测量及其临床意义

Measurement of the soft tissues of sole and its clinical significance

通过时５０例足底ｘ线片测量，测得足底非负重时各负重点皮肤与皮下软组织厚度分别为：足跟骨纵轴位１０．９ｍｍ；跟骨负重点为１５．７ｍｍ，第１跖骨头９．９ｍｍ；第５跖骨基底１５．２ｍｍ；第５跖骨头为１０．１ｍｍ。还测量了１０只新鲜足标本足底皮肤软组织厚度，其数值较ｘ线片差１５％左右，差异为标本制作时组织间液及血液放净后足底软组织相对用陷所致。足底厚度对负重时压力重新分布，吸收震荡是十分重要的，在足底缺损修复重建时要充分考虑到这一点，以便达到正常解剖生理功能．

he thickness of soft tissties of sole is meastired in 50 cases of roentgenograms.It wasrecorded as 15.7mm,9.9mm,15.2mm and 10.lmm in the regions of calcaneus,the firstmetatarsal head the fifth metatarsal basis and the fifth metataral head,The data from 10 freshfoot specimens is 15%less than that of roentgenograms for the collapse of soft tissues after lossof blood and interstitial fluid.The soft tissues of sole are importaiit for pressure distribution andconcussion absorption。 Priority shotild be given to the thickness of sole in reconstruction of plan-tar defect。
