经皮微创生物学技术的钢板固定治疗下肢长管状骨干骺部粉碎性骨折

Minimally invasive plate fixation in metaphyseal comminuted fractures of long tubular bones in lower extremities

目的探讨经皮微创生物学技术的钢板内固定治疗下肢长管状骨干骺部粉碎性骨折的临床价值。方法1999年4月～2001年10月,采用经皮微创生物学技术的钢板内固定治疗68例股骨或胫骨干骺部粉碎骨折的病人,术后早期功能锻炼。结果全部病例获得随诊,平均时间为10个月。65例术后X线检查显示复位和内固定位置满意,侧方成角8°1例,患肢缩短2cm2例。68例骨折全部愈合。按Klemm功能恢复分级标准,优56例,良10例,可2例。无深部感染、骨延迟愈合等并发症发生。结论应用经皮微创生物学技术的钢板内固定治疗长管状骨干骺部粉碎性骨折,可以达到医源性创伤小,骨折固定牢靠和早期功能锻炼的目的,具有重要的临床应用价值。

Objective To assess the clinical value of the mi nimally invasive plate fixation technique in treatment of metaphyseal comminute d fractures of long tubular bones.Methods Sixty-eight patients with metaphyseal comminuted fractures o f femur or tibia were treated with min imally invasive percutaneous plati ng and early recovery movement from April 1999to October 2001.Results All the patients were followed up for a mean time of 10months.The postopera tive radiograph showed that reducti on and internal fixation were satisfactory in sixty-five patients.Lateral angular deformity of 8°occurred in one c ase,and 2cm shortage of the lower lim b in two cases.Sixty-eight patients obt ained bone union and satisfactory clinical function.There were no deep i nfec-tion,nonunion or other complicatio ns.Conclusion For metaphyseal comminuted fractur es of long bones of lower extremities,minimally invasive percutaneous plate fixation is o f significant value due to the advant ages of less iatrogenic trauma,rigid fixation and early movement.[
