Abstract：Objective To analyze the clinical application value of Sureshot Distal Targeting System in locking intrameduallary nail operation for femoral shaft fracture. Methods Clinical data of 92 patients with femoral shaft fracture from Feb.2013 to Aug.2015 in our hospital, who had indications of intramedullary nail implantation, was retrospectively analyzed and divided into two groups according to the methods of implantation: the EM group(n=40) with magnetic navigation interlocking intramedullary nail technology (also known as Sureshot Distal Targeting System) and the FH group(n=52) with freehand distal locking nail technology.All the patients were followed up from 3 months to 1 year.The evaluation indexes of two groups, such as the duration of successful locking of nails, duration of intraoperative fluoroscopy, loss of blood, fracture union time and one-time successful rate, were compared.Incidence of inflection, broken nail, fracture nonunion, limb shortening and fracture recurrence, and Lysholm scores were compared between the two groups. Results The duration of successful locking of nails(7.74±2.02min), duration of intraoperative fluoroscopy (17.58±5.76)min, loss of blood(210.84±63.28)mL and one-time successful rate(95.00%) in EM group were superior to these in HF group(P<0.05);and the incidence of complications (7.50%) and excellent and good rate(95.00%) in EM group were found not significantly different compared with the FH group, P>0.05. Conclusion Sureshot Distal Targeting System is an ideal technology of locking intramedullary nail, with low duration of locking nail, high rate of one-time successful locking, low loss of blood, short fracture union time, short intraoperative fluoroscopy and low rate of complication, which is safe and reliable.
