Influence of Time of Weight-bearing Exercise on Rehabilitation after Internal Fixation of Femoral Neck Fracture in Elderly Patients

Objective To observe the effect of early weight-bearing exercise on postoperative rehabilitation of elderly patients with femoral neck fracture after internal fixation.Methods Sixty elderly patients with femoral neck fracture undergoing GardenⅠ,Ⅱclosed reduction and the hollow screw fixation between July 2018 and July 2019 in the People's Hospital of Shijiazhuang were entered into this study.According to different time of postoperative weight-bearing exercise,they were divided into observation group and control group.In the observation group,at 48 h after the operation,the patients were instructed to carry out partial weight-bearing exercise on the affected limb by holding both crutches,to carry out partial weight-bearing exercise on the single crutches at 1 month after the operation,and to remove the assistance for complete weight-bearing exercise on the crutches at 2 months after the operation.The control group avoided weight-bearing until 3 months after the operation.The incidence of deep vein thrombosis(DVT)of lower extremities at 3 d after operation,incidence of pulmonary infection,changes of serum nitric oxide(NO)and tumor necrosis factor-α(TNF-α)levels preoperatively and postoperatively,femoral head necrosis at 12 months after the operation,fracture non-unions and internal fixation failure,shortening of the femoral neck,femoral neck anteversion(FNA)angle,the Harris hip score,excellent and good rate,and visual analogue scale(VAS)score were compared between the two groups.Results At 3 d after operation,the incidence of DVT of lower extremities and pulmonary infection rate in the observation group were significantly lower than those in the control group(P<0.05).The incidence of fracture nonunion and internal fixation failure and rate of femoral head necrosis in the observation group was lower than that in the control group at 12 months after operation(P<0.05).Serum levels of NO and TNF-αwere significantly higher in the control group at 3,6 and 12 months after operation than in the observation group(P<0.05).There was no significant difference in the change rates of femoral neck shortening and FNA angle between the two groups at 12 months after operation(P>0.05).The Harris score,excellent and good rate of Harris score and VAS score were higher in the observation group than in the control group at 12 months after operation(P<0.05).Conclusion Early-stage weight-bearing exercise of the affected limb under professional guidance can effectively reduce the incidence of complications,including DVT of lower extremities,pulmonary infection,femoral head necrosis,fracture non-unions and internal fixation failure,and does not increase the incidence of shortening of the femoral neck and changes of FNA angle in elderly patients undergoing internal fixation for femoral neck fracture.In addition,it can significantly improve postoperative hip joint function,reduce postoperative pain,and accelerate the postoperative recovery.
