Treatment of the femoral peritrochanteric fractures with the femoral shaft fractures / 中国矫形外科杂志

[Objective]To investigate the effect of proximal femoral intramedullary nail with spiral blade for the treatment of femoral peritrochanteric fractures with femoral shaft fractures.[Method]From January 2002 to October 2006,21 patients of femoral peritrochanteric fractures with femoral shaft fractures were treated by minimal invasive technique with proximal femoral intramedullary nail and spiral blade.[Result]All 21 patients were followed up from 9 months to 5 years,with an average of 13 months,fractures healed in all patients.There was no nail and screw broken or loosening.The hip and knee joints of ingived limbs retained good function.[Conclusion]It is a good internal fixation operation for treatment of femoral peritrochanteric fractures with femoral shaft fractures(according to the patient's age,the type of fracture and the Singh index of the bone)by using minimal invasive technique with proximal femoral intramedullary nail and spiral blade,the key of treatment is the anatomic reduction of the fractures under minimal invasive surgery.

Use of the unreamed AO femoral intramedullary nail with spiral blade in nonpathologic fractures of the femur subtrochanteric / 中国矫形外科杂志

[Objective]To evaluate the unreamed femoral nail with spiral blade (UFN-SB) in the treatment of nonpathologic subtrochanteric femoral fractures.[Method]Twenty-seven patients who suffer subtrochanteric femoral fracture.Those fractures were classified with Seinsheimer’s way.Two cases of typeⅠ,9 cases of typeⅡ(5 of typeⅡ_A,3 of typeⅡ_B,1 of typeⅡ_C),12 cases of typeⅢ(7 of typeⅢ_A,5 of typeⅢ_B),3 cases of typeⅣ,1 case of typeⅤ.[Result]All cases were fellowed-up for 9~42 months,average 15 months.The authordidn't find any severe complications.All these patients could exercise early and bearing weight early.The authordidn't observe broken or loosen or quitted of this kind of internal fixation.[Conclusion]The UFN-SB is a better way for the treatment of subtrochanteric fractures of the femur.It can provide a satisfied restoration,a dependable fixation.It does good use to the concrescence of bone.It prevents short,rotation and varus angulation of femoral.The author get very good curative effect,less trauma,good sciatic function by using this kind of way to heal subtrochanteric femoral fracture.Especially in old people who suffer osteoporosis,this kind of interlocking way decreases the quantity lose of the bone,increases the contact area between bone and internal fixation,provides better angulation stability and rotation stability.
