Abstract:
[Objective]To discuss the feasibility and efficacy of the treatment of low subtrochanteric femoral fracture(LSFF) by using general interlocking intramedullary nail(GIIN).[Method]Between March.2000 and January.2006,47 cases(38 males,9 females) of LSFF were treated with limited incision and 6IIN.The mean age of the patients were 41.2 years(range 25 to 78 years).29 of them were injured in a traffic accident,7 in falling,6 in crush by a heavy object and 5 in pedestrain injury.According to Seinsheimer classification,11 cases were type IA,10 cases were type lB,19 cases were type ⅢB,and 7 cases were type Ⅳ(8 combined with other fractures)6 of these were open fractures(4 cases of Gustilo-Anderson type Ⅰ and 2 cases of type Ⅱ).The procedure included following step: all patients were treated with limited open reduction.The pyriform sinus entry point were localized with retrograde reamed;then,intramedullary nail was performed through the anterograde approach after limited reamed.All fractures were fixed statically.The operation time were from 50 minutes to 130 minutes(averaging 90 minutes).[Result]All the cases,were followed up for 11 to 34 months,with an average time of 33 months.The alignment of fracture was good.The bone union time were 2.5～6 months,the average 3.9 months.Fracture union rate was 100%.The functional evaluation was done by Sanders traumatic hip rating scale.of the 47 cases,31 were excellent,14 good and 11 fair.The excellent and good rate was 95.7%.There were no infection,implant breakage,limb shortening and varus deformity.[Conclusion]In treatment of LSFF,the GIIN is worth to recommend because it is simple for use,no need of X-ray monitoring during the operation,reliable,high union rate,rare complications,and good effects.Reasonable application of GIIN,better fracture reduction and early active functional rehabilitation(earlier activities and later weight bearing) are the keys to obtain a good clinical result.
