ABSTRACT
Objective To investigate the clinical efficacy of bone grafts containing bone morphogenetic protein 2 (Bone Conduction) treating of nonunion of femoral fracture after intramedullary nailing.Methods The clinical data of 49 patients with nonunion of femoral fracture after intramedullary nailing from August 2008 to August 2016 were analyzed retrospectively.They were divided into experimental group and control group according to different bone grafting methods.The experimental group (n =23) was treated with Bone Conduction combined with allograft bone grafting.The control group (n =26) was treated with autogenous bone grafting.The autogenous bone was taken from the ipsilateral ilium.The two groups were compared operative time,intraoperative blood loss,postoperative wound complications,hospitalization time,postoperative visual analog scale,mean image healing time and the score for distal femoral fractures after the operation.All patients were followed up for 12 to 24 months.Follow-up methods were divided into telephone follow-up and outpatient follow-up.The patients were followed up for outpatients before fracture healing.The patients were followed up by telephone after fracture healing.The healing time of fracture,the flexion and extension activities of the knee joint at 9 months after operation were recorded.SPSS19.0 statistical software was used to analyze the data.Measurement data were expressed as ((x) ±s).The independent sample t test was adopted in measurement data and the counting data was tested by Chi-squared test.Result In the experimental group,operative time was (138.7 ± 34.6) minutes,intraoperative blood loss was (315.4 ± 52.8) ml,postoperative wound complications was 0 case,hospitalization time was (8 ± 3) days,postoperative visual analog scale was 5 scores,but in the control group,operative time was (170.5 ± 32.5) minutes,intraoperative blood loss was (367.2 ± 56.4) ml,postoperative wound complications was 3 cases,hospitalization time was (13 ± 2) days,postoperative visual analog scale was 8 scores.There were significant differences between the two groups,P <0.05.All patients who followed up for 12-24 months were recovered,with an average follow-up of 15 months.Mean image healing time in the experimental group and control group was separately(4.9± 2.5) months,(5.2 ± 2.8) months.The excellent and good rates ofthe score for distal femoral fractures 9 months after the operation was separately 95.7%,96.2%,there was no significant difference between the two groups,P > 0.05.Conclusions Bone graft material containing bone morphogenetic protein 2 (Bone Conduction) has the advantages of simple operation,less trauma,less complications,high osteogenic activity and good bone graft effect are equalled with iliac bone graft,the bone graft material containing bone morphogene protein is an effective method to treat nonunion of femoral fracture after intramedullary nail.
