塌陷

Results Early signs of ANFH using CT showed that, in 38 femoral heads 31 cases, there were radiate star shape of high density osteosclerosis of the trabeculae in 13 femoral head.Twenty five femoral heads showed osteosclerosis and trabeculae structure disappearing and vague,incoordinately low ostedensity area and cyst change.There were fracture under the cartilage and light subsid in 5 cases.The cases in stage Ⅰwere given decompression, while the pationtsresul in stageⅡand stageⅢ were given decompression and ostetransplant.

结果：早期ANFH的CT表现：31例38个股骨头，其中13个股骨头骨小梁呈放射状高密度的"星状征"，骨小梁境界清楚、锐利，属Ⅰ期；25个股骨头表现为骨硬化，骨小梁结构消失、模糊不清，骨密度减低及囊性改变，属Ⅱ期；并有5个股骨头在Ⅱ期影像学改变基础上出现软骨下骨折及轻微塌陷，属Ⅲ期。

BACKGROUND: The silica gel prosthesis and os lenticulare were widely used as substitute for lunar bone, which can result in complications, such as periostitis, bone resorption as well as carpal bone collapse.

摘要背景：月骨切除后以往用硅胶假体和豆状骨移位等替代，短期有一定疗效，但可发生硅胶性骨膜炎、移植骨吸收和腕骨塌陷等并发症。

Since the 50s, because of swift development of human engineering maneuver, the karst conceal in the subterranean sinks also emerges as the times require. The frequency that happens is more and more great against intensity .The perniciousness is also broaded at the same time.

自50年代以来，由于人类工程活动的迅速发展，隐藏在地下的岩溶塌陷也应运而生，发生的频率与强度愈来愈大，危害性也随之增大。

In the procedure of researching and developing project, brings forward the method of fast establishing new project based on template file; develops the module used for forecasting movement and deformation of multiple random-shape faces according to probability integral principle; according to the traits of forecasted data, puts forward a new algorithm of drawing isoclines in Maplnfo environment; designs the new algorithm of drawing section plane and the new calculation of area and volume of subsided section based on isoclines; at the same time, gives the rale of classifying mine surface damage under GIS environment on the basis of GIS uncertainty theory.
