动力加压钢板内固定骨干骨折

INTERNAL FIXATION FOR SHAFT FRACTURES WITH DCP

探讨动力加压钢板（ＤＣＰ）内固定治疗骨折的实用价值。回顾１９８９－０５～１９９５－０５间采用仿ＡＯ－ＤＣＰ内固定２００例２３１处长骨干骨折。平均随访２５６个月，无骨不连接与畸形愈合，功能满意率为９５５０％。结论：ＤＣＰ虽属偏心位内固定，其应力遮挡作用与对骨供血的不利影响，可致固定骨段骨质疏松，但临床结果证实，其缺点不应被视为去钢板后再骨折的主要原因，因此，ＤＣＰ内固定治疗长骨干骨折仍不失为先进的方法。

To evaluate the clinical value in the internal fixation for shaft fractures with DCP(Dynamic Compression Plate).It was reviewed that 231 sites of 200 patients suffering from shaft fractures of long bone were treated by the internal fixation with DCP,from May,1989 to May,1995.The follow-up for the cases is 256 months in average.200 patients were all healed without non-union or malunion,and the rate of satisfactory functional results were seen in 9550% of the cases.DCP is a kind of eccentric fixation,and the stress shielding and interference with blood supply from DCP may result in osteoporosis of plated bony segments,but its shortcomings should be not thought of as a main reason of refractures after removing plates out.
