饮茶过量氟骨症X线表现

Analysis of Radiological Appearance of Excess tea Skeletal Fluorosis

本文分析了新疆５个民族１２６例饮茶过量所致氟骨症Ｘ线的表现。在长骨中，前臂或小腿骨周骨化率９３．７％，以腕骨为多见的骨吸收点２７．８％，骨皮质厚７．９％，骨纹理粗疏２４．６％，骨纹理紊乱１３．５％，关节退行性变３２．５％，以前臂小腿骨周骨化率为最高。同时观察到骨盆和腰椎骨密度增高２９．１％，骨质疏松１４％，韧带和肌腱附着处骨化３８．４％，骨纹理改变５８．１％。除骨吸收斑点外，此型氟骨症Ｘ线表现类似于饮水型氟骨症。氟骨症常规Ｘ线检查也适于饮茶过量氟骨症诊断。

A group of 126 cases radiographes of excess tea skeletal fluouosis from five nations in Xinjiang were analysed. In long bone, it was found that the rate of periosteal ossification in forearm and leg, of degenerative changes in joint of knee and elbow, of thicken and coarse trabeculation in bone, of bony trabeculae disorder, and of bone resorption spots especially seen in carpal bones, was 93.7%,32.5%,24.6%,13.5% and 27.8%, respectively. The rate of periosteal ossification of forearm and leg was the highest among the signs of X ray photograph. Marked osteosclerosis of 29.1%, osteoporosis of 38.4% in ligaments, muscular attachments and obturatoria membranae, and changes of bony trabeculae of pelvis and lumbar vertebrae of 58.1% had been observed. The radiological appearance in this type type of skeletal fluorosis was resemblance to that in drinking water type besides the sign of bone absorption in carpal bones. It proves that routine X ray examination for diagnosing skeletal fluorosis is also suitable to excess tea skeleta fluorosis.
