Abstract:

BACKGROUND: Fracture fixations are divided into an intramedullary nail fixed and steel plate fixed two methods, how to choose a fixation devices for clinical curative effect and postoperative complications is crucial.
OBJECTIVE: To make a clinical curative effect comparison using reconstruction interlocking intramedullary nail (double neck and shaft fracture nail, DNS) and dynamic hip screw (DHS) steel in treating the femoral complexity fractures .
METHODS: Totally 70 cases of femoral fractures merger with side femoral neck fracture, between rotor fracture, subtrochanteric fractures, femoral fractures were analyzed retrospectively. Internal fixation implant was used DNS and DHS.
RESULTS AND CONCLUSION: All cases were followed-up 3 months, early functional recovery and fracture healing time in the DNS group were better than that of the DHS group. Relative complications in the DHS group were easily found hip equinovarus and fixation failure, and in the DNS group were easily found screw loosening. There was no significant difference of incision infection and fat embolism syndrome in the two groups. DNS has static and dynamic fixed function of two fractures. It is accord with biomechanics reconstruction principles and fracture healing fast. DNS is a better and effective internal fixation device as compared with DHS.
