陕西省定边县地方性氟骨症X线分析

Radiological analysis of endemic skeletal fluorosis in Dingbian county, Shaanxi province

目的观察定边县饮水型地方性氟中毒骨关节损害的放射学特点。方法在定边县平原区随机选拍片对象共443人,拍摄骨盆、右前臂、右小腿正位片。结果定边县氟骨症的X线检出率为72.23% ,前臂、小腿阳性征象的检出率高于骨盆,X线诊断与临床诊断不完全吻合,X线检出率、X线改变指数与水氟之间呈正相关。结论临床表现与骨X线改变的不一致,给氟骨症的早期诊断造成困难,应加强对其机理的探讨。

Objective To observe the radiological characteristics of bone and joint damages of patients living in Dingbian county, an area of fluorosis related to water. Methods The observed population was randomly selected in the plain of Dingbian county to take X-Ray film on pelvis, right forearm and right leg. Results The detective rate of skeletal fluorosis reached 72.23%, that of forearm and leg being higher than that of pelvis, respectively. The X-Ray diagnosis did not correspond to clinical one. The X-Ray detective rate and X-Ray change index were positively correlated with fluoride content in drinking water. Conclusions The early diagnosis is difficult because of the disagreement between clinical features and X-Ray changes, whose mechanism needs to be studied.
