摘要目的:为了增强治疗小儿先天性髋脱位造盖术造盖的支撑力及抗压强度.方法:将传统的翻转造盖术扁放骨片和碎骨块改为立放3枚三角形骨块,在传统插入造盖上方加1枚立式骨块,取名"强力造盖术".若真臼宽度够,只是髋臼指数大,应选用强力翻转造盖术;若假臼明显形成,将真臼顶挤压变窄,则应选用强力插入造盖术.结果:近5年来应用强力造盖术治疗小儿先天性髋脱位243例,315髋次,只发现1例1髋插入造盖折断.结论:基本上解决了造盖折断和吸收问题.因此,由原来多选用骨盆截骨术,改为现在多选用造盖术.

abstractsObjective:To enhance the shelf supporting forces and intensity of resistence in shelf operation on congenital hip dislocation.Methods:The flat piece and fragments of bone were changed into three pieces of vertical triangle bone and added a vertical bone segment.The reinforced reversion shelf method should be adopted in acetabulum with enough width but a large acetabular index.If the false acetabulum was formed and narrowed the true acetabulum,the inserting shelf operation should be chosen to widen the true acetabulum.Results:The operation was adopted in 243 cases(315 hips),only one had fracture of the inserting shelf.Conclusions;The authors prefer the shelf operation to the used innominate osteotomy to treat the CDH.The problems of fracture and absorption of the shelf have been solved basically.
