摘要
作者应用胎儿,死后婴儿股骨近端进行大体解剖和切片组织学检查,对优板各层发育演变进行了描述。根据其组织学特点将骺板分为长短两臂,长臂由颈骺板和转子骺板组成,短臂由头骺板和钩骺板构成。2岁时颈骺板消失;观察了优板内血管的分布形式。胎儿时期有交通血管存在,来源于骨骺侧,至新生儿期消失,血运屏障建立,骨骺和于骺端形成两个独立的血液循环系统;探讨了软骨周围骨化沟与骺板横径增殖的关系,认为骨化均参与骺板横径增殖的证据不足,有待进一步研究,可望通过对它的研究为临床某些疾病的解释提供有用的资料。
AbstractThe authors studied the developnlent and evolu-tion of the growth plates of the proximal end of the fe-mur using specimens procured from fetus and died in-fants. According to the data obtained, the authors di-vided the growth plates into the long arm, which con-sisted of the neck and the great trochanter growthplates and the short arm that composed of the headand the hook growth plates. They are named as thehead, hook, neck and great trcchanter growth platesrespectively, By the age of two , the neck growthplates disappeared, observation of the blood supply tothe growth plates revealed that there were communi-cating vessels between the epiphysis and the metaph-vsis in the fetus specimens. These vessels originatedfrom the epiphysis and flew into the metaphysis andthen closed at the period Of neonate when the vascularbarrier began to setup. The epiphysis and the metaph-vsis were supplied by two different blood circulationststems. The conventional concept of the increases inthe diameter of the growth plates being attributed tothe Ranvier’s groove seems to be insufficient andawaits further study. It is the hope of the authorsthat , the findings in this study can provide some basicidea for the explantion of the deformities encounteredclinically.
