The curative effect comparison between prolonged third generation of gamma nail and prolonged dynamic hip screw internal fixation in treating femoral intertrochanteric fracture and the effect on infection.

The objective was to explore the curative effect of prolonged third generation of gamma nail (pTGN) and prolonged dynamic hip screw (pDHS) internal fixation in treating femoral intertrochanteric fracture, and analyze the incidence rate of infection for better clinical diagnosis and treatment. Sixty five patients with femoral intertrochanteric fracture during February, 2011-February, 2013 were selected and divided into two groups, with one receiving pTGN (control group) and the other one receiving pDHS internal fixation (observation group). The clinical effects of two groups were compared. In control group, the excellent and good rate was 78.13 %, the total effective rate was 87.5 %, and the total complication rate was 6.24 %; in observation group, the excellent and good rate was 78.79 %, the total effective rate was 90.91 %, the total complication rate was 6.06 %; there was no statistical difference between two groups (p > 0.05). The operation time, the intraoperative fluoroscopy time, and the total blood loss had statistically significant difference between two groups (p < 0.05); however, the differences of the total length of incision, the length of preoperative hospitalization, postoperative ambulatory episode, and the length of stay between two groups were not statistically significant (p > 0.05). Both pTGN and pDHS internal fixation were effective on femoral intertrochanteric fracture, with pDHS internal fixation having better overall efficiency.
