逆行交锁髓内钉微创内固定治疗股骨下段及髁上骨折

目的探讨便携式下肢手术支架下逆行交锁髓内钉内固定治疗股骨下段及髁上骨折的效果。方法采用自制便携式下肢手术支架、牵开复位器等辅助逆行交锁髓内钉微创内固定治疗55例股骨下段及髁上骨折患者。结果手术时间50～110(78±22)min;术中出血量100～600(260±110)ml。患者均获得随访,时间12～35个月。根据Karlstrom和Olerud功能评定标准进行疗效评定:优27例,良24例,中4例,优良率为92.7%。结论应用便携式下肢手术支架、AO牵开复位器及带手柄的Schanz钉辅助骨折复位等方法,使股骨逆行交锁髓内钉的手术操作更加便捷。

Retrograde intramedullary interlocking nail under minimally invasive surgery for distal or supracondylar fractures of femur

Objective To discuss the effect of treatment of distal or supracondylar fractures of femur with retrograde intramedullary nail under portable bracket of lower limb.Methods 55 patients of distal or supracondylar fractures of femur were fixed with femoral retrograde intramedullary nail,application of minimally invasive method such as portable bracket,AO large distractor and Schanz screw.Results The average operative time was 50～110(78±22) min,the average blood loss was 100～600(260±110) ml;All cases were followed up for 12～35 months.According to assessment systems of Karlstrom and Olerud,the clinical results were excellent in 27 cases,good in 24 and fair in 4,and the excellent and good rate was 92.7%.Conclusions Retrograde intramedullary nail under portable bracket of lower limb on combined AO large distractor and Schanz screw used in distal or supracondylar fractures of femur is one of effective methods,and convenient for operation.
