RESUMEN
Objective To investigate the clinical study on drynaria injection for delayed healing of fracture patients.Methods 108 patients with fracture delayed union from February 2010 to February 2016 in our hospital were selected and randomly divided into the control group and the experiment group by different treatment,54 cases in each group.The control group were treated by conventional therapy,the experiment group were treated with drynaria rhizome injection on the bases of control group.The total effective rate,serum alkaline phosphatase,NGF and BMP-2 levels were observed and compared after treatment.Results After treatment,the total effective rate of experiment group was higher than control group (P<0.05);After treatment for 7 and 14 days,the serum alkaline phosphatase level of the two groups were significantly increased (P<0.05),and compared with the control group, the serum alkaline phosphatase content of the experimental group was higher (P<0.05);After treatment for 7 and 14 days,the serum NGF and BMP-2 levels of two groups were significantly increased(P<0.05),and compared with the control group,the experimental group was higher than those in the control group.Conclusion Injection of rhizoma drynariae in the treatment of delayed healing of patients with significant effect,increase the levels of serum alkaline phosphatase, serum NGF and BMP-2,promote fracture healing in patients and improve clinical efficacy.
RESUMEN
Objective To compare the proximal femoral locking plate (LPFP) and proximal femoral intramedullary nail-spiral blade (PFNA) in minimally invasive internal fixation for elderly patients with intertrochanteric fractures.Methods One hundred and thirty patients aged over 60 years with intertrochanteric fractures were treated with minimally invasive internal fixation from January 2010 to June 2013,among them LPFP was applied in 69 cases and PFNA in 61 cases.The operation time,the numbers of intraoperative X-ray fluoroscopy,intraoperative blood loss,postoperative flow and decreased postoperative hemoglobin,postoperative complications,medical expenses,fracture healing time,postoperative hip Hariss function score were documented and compared between two groups.Results There were no significant differences in intraoperative blood loss [(132 ± 95) and (110 ± 79) ml],postoperative draining [(44 ± 16) and (41 ± 17) ml],decreased postoperative hemoglobin,fracture healing time [(10.5 ± 1.0) and (10.4 ± 1.5) weeks] and postoperative hip Hariss function score (87 ± 10 and 90 ± 8) between two groups.In LPFP group the number of intraoperative X-ray fluoroscopy (8.1 ±0.8 and 8.6 ± 0.9),hospitalization expenses,postoperative complications (7/69 and 16/61) were less than those in PFNA group (P＜0.05 or 0.01),however,the operation time was longer (P＜0.01).Conclusion LPFP may be a better choice in internal fixation for elderly patients with intertrochanteric fractures.
