Abstract:
Objective To investigate the possibility,surgical methods,outcome and surgical indications of minimal invasion dynamic hip plate (MIDHP) through percutaneous limited open reduction in treatment of subtrochanteric femur fractures.Methods All cases underwent percutaneous limited open reduction with MIDHP.Duration of operation,intraoperative bleeding volume,length of incision,incidence of intra-or post-operative complications of all case were recorded.X-ray films were reviewed periodically after operation to analyze aspects of fracture displacement,loosening of intemal fixation,screw cutting femoral neck,screw penetrating out of or withdrawing from femoral head,bending or breaking of internal fixation,and fracture healing.Hip joint function was evaluated according to Huang' s criteria.Results Operation lasted for 45-55 minutes (average 50 minutes),showing the incision length of 4.0-5.0 cm (average 4.5 cm) and blood loss of 50-200 ml (average 150 ml).A total of 21 cases were enrolled in the study and were followed up for 6-28 months (average 18 months).In the follow-up,loosening or bending of internal fixation,fracture displacement,screw cut-out,and screw penetrating or withdrawing from femoral head did not occur.In the meantime,incision,bone,and joint were not infected.All cases had bony fusion within 3 months with the fracture healing rate of 100％.According to Huang' s criteria,hip function was excellent in 19 cases and good in two.Conclusions MIDHP with percutaneous limited open reduction is characterized by less trauma,small incision,less blood loss,less postoperative complications,firm fixation,early functional exercise,free load,and good hip functional recovery and hence is suitable for cases of different subtrochanteric femur fractures,especially for cases combined with osteoporosis.
