To study the double reverse drawing technology auxiliary closed reduction and PFNA intertrochanteric fractures treated by internal fixation.

The clinical effect of selection in May 2015 to May 2017 in our hospital for treatment of 80 patients with intertrochanteric fractures as the research object, the loss of visitor 10 cases, according to the difference between the reset mode, it can be divided into bidirectional group and traction bed group. The differences of the two groups were compared such as operation time, intraoperative blood loss and other indicators.

70 patients were followed up after surgery with a follow-up rate of 87.5%, an average of 14 months. There were male 31, female 39, and the average age was (83.8±0.5). Operative time, blood loss, intraoperative fracture reduction time, and intraoperative fluoroscopy times of bidirectional group [(76±11) min, (80±90) ml, (12±3) min, (20±2) times] were less than raction bed group [(85±13) min, (100±104) ml, (25±3) min, (25±3) times], the difference was statistically significant (t=1.624, P=0.043; t=-1.773, P=0.037; t=1.362, P=0.041; t=-2.757, P=0.035). The hip and knee function scores of the bidirectional group at 1 and 3 months after surgery were significantly better than those of the traction bed group, the differences were statistically significant (P<0.05). There was no significant difference in the scores of the two groups at 6 and 12 months after operation, the difference was not statistically significant (P>0.05).

Bidirectional reduction intertrochanteric fracture can make surgery easier, high quality of reduction, blood supply to protect the surrounding tissue, and the operative time is short, quick recovery, the recent excellent results.
