足跗骨发育变异的X线研究
Journal of Practical Radiology(2003)
Abstract
目的研究足跗骨在不同生长阶段发育变异的发生率,年龄分布和形态特点.方法对出生后~18岁正常人群右足正、侧位X线照片2035例(男1068例,女967例;1岁一个年龄组,每组38~98例)进行观察.结果出现发育变异721例(35.43%),其中男356例(33.33%),女365例(37.75%).暂时性发育性跟骨刺(1.10%)和跟骨多骨化中心(0.50%)见于0~5岁;内楔骨不规则骨化(0.70%),内楔骨双骨化中心(0.95%)和舟骨双骨化中心(1.74%)见于2~8岁;跟骨营养血管孔(3.44%)和跟骨骨髓窦(16.10%)见于1~18岁;距骨三角骨(2.64%),胫外骨(或副舟骨)(6.18%)和跟距骨桥(7.04%)见于7~18岁.结论足跗骨生长发育变异对常见足部疾病的鉴别诊断有重要意义.
