RESUMO
[Objective]To explore clinical effect of DHS combined with hollow traction bolt treating thighbone interrotor fracture. [Method]From May 2003 to July 2006,apply DHS combined with hollow traction holt to treat thighbone interrotor fracture 9 ca- ses,6 males,3 females,aged 47～72,62.6 in average,5 cases of left side,4 right side;classify under Evan's:5 cases of typeⅡ, 2 ofⅢ,2 ofⅣ.[Result]Follow up for 6～21 months,12 months in average.Appraise the clinical effect by Huang Gongyi's standard,7 cases were very good,1 good,1 bad,the good rate was 89%.[Conclusion]DHS combined with hollow traction bolt treating thighbone interrotor fracture can obviously increase stability of fracture point,reduce local rotation,helpful to fracture cure and early exercise,as well as the complication.
