先天性马蹄内翻足足骨发育异常X线表现

目的:研究马蹄足足骨生长发育特点，为手术治疗和临床研究提供解剖学依据，探讨治疗原则。方法:对我院1997年以前收治的单侧先天性马蹄内翻足患儿双足摄X线片和CT三维重建图像，了解其畸形组成、足骨发育，与健侧比较，从而探讨维持畸形的解剖学、力学因素。结果:患足中足及跟距骨均有生长发育异常，骨关节改变，力线改变，促进或参与了畸形发生、畸形保留。结论:了解先天性马蹄内翻足病理解剖结构，分析畸形维持原因，为尽早手术治疗提供依据，为临床研究提供足骨生长发育的特点。规范手术治疗原则。

Foot bone development in congenital clubfoot

Objective To study the characteristics of bone development of congenital clubfoot (CCF) so as to obtain principle for operation and treatment of CCF and anatomical basis for research. Methods All patients treated by operation till the end of 1997 were reviewed. Their bone development was studied by X-imagings and CT 3-D remodeling imagings taken before operation. The strength distribution of the foot skeletal system,and the factors affecting cure were also studied. Results Most of the development of the foot bones and intertarsal joints were abnormal. The line of force was changed and this encouraged and quickened the deformity to develop. Conclusions After understanding the anatomical abnormality in CCF and the reasons of deformity,clinical evidence is established for early treatment so as to allow bone development.
