Development and clinical application of new designed Kirschner wires guider for patellar fracture / 局解手术学杂志

ABSTRACT

Objective To develop a new designed Kirschner wires guider for patellar fracture,and to evaluate its clinic outcomes.Methods From October 2010 to November 2015,totally 72 patients with patellar fracture were detected for this study.Divided them into 3 groups, named as the second-generation guider group,the first-generation guider group and the control group.And then evaluated the clinic outcomes in treatment of patellar fracture of the 3 groups.Results The surgery time,accuracy of placement needle position of the second-generation guider group were better than the other two groups with significant statistical differences (P <0.01).And the clinic outcomes of the first-generation guider group were better than the control group,and the differences were statistically significant (P <0.05).Conclusion The second-generation Kirschner wires guider is reasonable in design and convenient for use.Moreover,it can improve the accuracy and quality of surgery,reduce the operation time,and enhance the clinical effects.
