Curative Effect Observation of Percutaneous Cannulated Screws Fixation Assisted by Robot Navigation and Poking Rduction Technique for Femoral Neck Fractures
Abstract：Objective To discuss the effect of fixation with percutaneouscannulated screws assisted by robot naviga-tion and poking reduction technique for femoral neck fractures.Methods From May 2013 to June 2015,13 patients with femoral neck fracture were treated by internal fixation with percutaneouscannulated screws assisted by robot navigation and poking reduction technique.Record the operation time,X-ray fluoroscopy time,blood loss,total drilling times,the parallel degree of screws,the healing rate of fractures,the Harris scores of all patients.Results All patients were fol-lowed up for 12~25 months with an average of (18.6±6.6)months.Average operation time was(92.2±6.7)min.Aver-age frequency of guide pin insertion was (5.2±1.2)times,X-ray fluoroscopy time was (16.1±4.1)s,blood loss was (10.1±2.1)mL.Garden index was (173.3±8.3)°in AP view and (171.1±11.1)°in the lateral.The X ray showed that the fracture healing rate was 100 percent.The verage healing time was (5.8±1.3)months,Postoperative Harris hip score was (86.9±5.1).The latest follow-up revealeds that none nonunion of fracture or femoral head necrosis was foun-ded in the all patients.Conclusion Cannulated screw fixation assisted by robot navigation and poking reduction tech-nique has high clinical application value.Which lead to more accurate positioning,better hip function ,less surgical trau-ma and X-ray exposure times.It is a good method to treat femoral neck fractures.
