应用AO特殊钢板治疗近关节骨折（附45例报告）

目的：探讨AO特殊钢板在肢体近关节骨折的治疗效果。方法：1998年6月以来应用AO特殊钢板治疗肢体近关节骨折45例，其中股骨粗隆部骨折28例用动力髋螺钉（Dynamic Hip Screw,DHS)固定；股骨髁上、髁间骨折7例用髁钢板及动力髁螺钉（Dynamic Condyle Screw,DCS)固定；Pilon骨折6例用1／3环形腓骨钢板及三叶蓿形支持钢板固定；肱骨外科颈骨折4例用T形支持钢板固定。结果：平均随访10个月，股骨粗隆间及髁上髁间骨折，肱骨外科颈骨折在术后3－4个月骨愈合，Pilon骨折有4例在术后6个月骨愈合。本组未出现手术并发症，关节功能恢复满意。结论：AO特殊钢板的设计合理，组织相容性好，对复杂近关节骨折能起到坚强固定，满足关节早期功能锻炼的作用，疗效优良。

Treatment of Extremital Fracture near Articulation using AO Special Plate

To evaluate the results of AO special plate in the treatment of extremital fracture near articulation.Methods:Since June 1998,45 cases of extremital fractures near articulations were operated by AO special plates.Among them,28 patients of intertrochanteric fractures were treated with Dynamic Hip Screw(DHS);7 patients of supracondylar and intercondylar fractures of femur were treated with Dynamic Condylar Screw(DCS);6 cases of Pilon fractures were operated with one-third circular plates and Medicago sativa plates,and 4 cases of fractures of surgical neck of humerus were used T-shaped plates.Results:The mean duration of the follow-up was 10 months.Bone healing was seen at 3～4 months in the fractures of intertrochanteric,femoral condyle and humeral surgical neck,at 6 months in 4 cases of Pilon fractures.Other 2 cases of Pilon fractures had porotic stage at 2～3 months after operation.There was no operative complications in these cases.Recovery of articular function was satisfactory.Conclusion:AO special plate had a rational design and a good histocompatibility.It possessed enough stability meeting the need of early functional exercise and was very suitable for complicated fracture near articulation.
