儿童大骨节病掌骨与腕骨基本X线征像图释

Interpretations of the basic X-ray signs of metacarpal and carpal bone of Kaschin-Beck Disease in children

目的总结汇编儿童大骨节病掌骨与腕骨基本X线征像,用以提高大骨节病诊断的准确性。方法收集8个单位保存的儿童大骨节病掌骨与腕骨改变的X线片,采用扫描仪扫描,Photoshop软件进行分类处理。结果获得了儿童大骨节病掌骨与腕骨包括囊变、假性囊肿、干骺端不整伴硬化、干骺端增宽伴硬化、干骺端凹陷、干骺端凹陷伴硬化、骨竖刺形成、骨端凹陷、骨端骨性关节面缺损、骨端切角征、骨端骨刺、骨端烟头征、骨骺变形、锥形骨骺、一字型骨骺、骨骺碎裂、八字形骨骺、骨骺的延迟(骨骺溶解、骨骺缺失)、腕骨的局部硬化等5种类型,19种基本X线征像。结论填补了儿童大骨节病X线影像学改变的空白,为正确诊断大骨节病提供了详实的影像学参照。

Objective To summarize the basic X-ray signs of Kaschin-Beck disease（KBD） in children and improve the accuracy of Kaschin-Beck disease diagnosis. Methods The KBD children＇s hand X-ray film（ common or digital） were collected from 8 units, the basic X-ray signs of KBD were classified and sorted. The pathological basis of various X-ray signs were analyzed. The screenshots were gotten by using photoshop software. Results There were 19 kinds of basic X-ray signs in the hands of KBD children, including Cystic change, Pseudocyst, Serration change and sclerosis of metaphysis, Broadening and sclerosis of meta- physic, Indentation of metaphysic, Indentation and sclerosis of metaphysis, Bone vertical spur formation of metaphysic, Indenta- tion of distal end phalanx, Articular surface defects of distal end phalanx, Corner cut sign of distal end phalanx, Bone spur of distal end phalanx, Burning tip in cigarette-like on sub-articular surface of distal end phalanx, Deformation of epiphysis, Cone- shaped epiphysis, Inline epiphysis, Fragmented epiphysis, Splayed epiphysis, Delayed appearance of epiphysis, （ Dissolution of epiphysis, Deletion of epiphysis） and Marginal sclerosis of carpal bone. Conclusion The X-ray image changes of distal end phalanx are the characteristic changes of KBD.
