阿坝州壤塘县大骨节病区与四川成都地区儿童手部X线对比分析

目的通过与四川成都地区正常儿童手部X线片对比分析,了解四川阿坝州壤塘县地区儿童大骨节病发病情况及特点。方法选取4~16岁阿坝壤塘南木达乡异地育人学校学生与成都地区正常儿童对比分析。全部儿童进行双手X线摄片,X线片由来自四川省疾病预防控制中心、四川大学华西医院骨科、影像科、风湿免疫科及小儿外科共10人组成的阅片专家组共同判读。结果壤塘县儿童手部X线片显示锥形骨骺及异常改变多,14.6%的儿童出现食指、中指、环指近、中节多发、对称的异常改变,成都地区儿童未发现。结论说明在政府积极干预下,一方面壤塘县大骨节病表现非典型化,另一方面,其致病因子依然存在。探索大骨节病致病机理,寻求早预防,早诊断的方法,依然是我国骨科和地病学者需共同承担的责任。
