Treatment of Intertrochanteric Fracture with Minimal Invasive Surgery Assisted by Computer Navigation System

Objective Using computer navigation system helps to minimize the invasion of intertrochanteric fracture internal fixation operation.Methods From August 2006 to September 2010,we had treated 84 cases of intertrochanteric fracture in our hospital.76 cases(28 male,48 female) were treated with the intramedullary nail(Garma nail,PFNA nail and EPFN nail).The patients aged from 59～96 years,with an average of 76.8 years old.In 27 of them,fracture was fixed assisted by computer navigation system,and the others undergone routine procedure.The operation time,blood loss,times of X-ray during operation and the size of the incision were compared between the two groups.Results The data shows that the computer-assisted group had less blood loss,shorter the exposure time under the X-ray and smaller size of the incision.Conclusion The computer navigation assisted fixation of the intertrochanteric fracture is a minimall invasive choice.
