Objective To investigate the application value of ratio of elastic intramedullary nail diameter(ND)to me-dullary canal diameter(MCD)in the treatment of femoral shaft fractures in children.Methods The 90 children of femoral shaft fractures treated with elastic intramedullary nails fixation were divided into an observation group(30％ND/MCD＜40％,47 cases)and a control group(ND/MCD ≥ 40％,43 cases),according to different ND/MCD lev-els.The perioperative indicators,surgical time of removing internal fixation,fracture healing and knee flexion mobility were compared between the two groups.Results All patients were followed up for 6～10(8.16±0.57)months.The intraoperative bleeding volume,surgical time,hospitalization time,surgery time of removing internal fixation and frac-ture healing time in the observation group were all lower(shorter)than those in the control group(P＜0.05);there were no statistical differences between the two groups in terms of the start of mobilization,time of callus formation,knee flexion range of motion at postoperative 3,6 months,and incidence rate of complications(P＞0.05).Conclu-sions For the treatment of femoral shaft fractures in children,choosing an elastic intramedullary nail with a diameter of 30％≤ ND/MCD＜40％is more convenient for surgical operation,with less intraoperative bleeding,shorter surgi-cal time and removal of internal fixation,shorter hospital stay,shorter fracture healing time,and satisfactory early clini-cal results.
