动力髁钢板内固定矫治儿麻后遗症股四头肌瘫痪的临床研究

Clinical research about the therapeutic effect on quadriceps femoris paralysis by DCS internal fixtion

目的 探讨动力髁钢板 (DCS)内固定对矫治儿麻后遗症股四头肌瘫痪的效果。方法 股骨髁上楔形截骨治疗儿麻后遗症股四头肌瘫痪 35例 ,其中采用普通钢板固定 2 2例 ,动力髁钢板 (DCS)内固定 13例 ,平均随访 2 .3年 ,对比分析两组手术的膝关节功能恢复及并发症情况。结果 DCS固定与传统钢板固定组患者的手术优良率无明显差异 (P >0 .0 5 ) ,但住院时间、骨折愈合时间、下地行走时间明显缩短 (P <0 .0 1) ,并发症较少 (P <0 .0 1)。

Objective To investigate the therapeutic effect on paralysis of quadriceps femoris by dynamic condyle screw(DCS) internal fixtion.Methods 35 patients with paralysis of quadriceps femoris for poliomyelitis sequela were operated with wedge-shaped supracondyle osteotomy,among which 22 were fixed internally with common plate and 13 were done with DCS.The recovery and complications between the two group were analyzed after a follow-up for 2.3 years.Results Compared with the patients treated by common plates internal fixation,patients treated by DCS obtained the same recovery but in shorter period of time and showed less complications.Conclusion DCS internal fixtion has marked superiority in the treatment of paralysis of quadriceps femoris.
