Tian RH, Zhang QM, Chu FI, et al. - Researchers included a total of 90 individuals with intertrochanteric fractures who were surgically treated, (48 males and 42 females with an average age of 70.5 ± 7.2 years) between January 2010 and June 2013 in order to compare the efficacy of three-point locating vs routine locating techniques for implanting helical blades for proximal femoral nail anti-rotation-II in the treatment of trochanteric fractures. There were 45 cases of A2.1, 35 cases of A2.2, and 10 cases of A2.3 according to the AO classification. Individuals were classified into two groups: the three-point group and the routine group, with 45 individuals in each group. Compared with the routine group, the three-point group was significantly superior in terms of total operation time, elapsed time for implanting the helical blade, intraoperative blood loss, x-ray exposure time, and tip-apex distance. It was indicated that the three-point locating method was found to be a faster and more accurate compared with the routine locating method.
