The X\u2010ray films were strictly reviewed by three trauma surgeons and a professional radiology doctor. Patients over 60\u2009years of age who met the following criteria were included: (i) sustained low\u2010energy trauma; (ii) a two\u2010part fracture; (iii) fracture line located at the base of the femoral neck and that was medial to the intertrochanteric line and exited above the lesser trochanter but was more lateral than a classic transcervical fracture. Follow\u2010up time should be longer than 6\u2009months. A total of 52 patients who met the inclusion criteria were selected. The average age at diagnosis was 75.1\u2009years (range, 63\u201391\u2009years); 13 patients were men and 39 were women. The same proximal femoral nail anti\u2010rotation devices and the same surgical procedures were applied to all patients. Postoperative radiographic union time and modified Harris hip scores were used as major indicators for evaluating the effectiveness of surgery.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The average follow\u2010up period was 22.5\u2009months (18.5, 23.9, and 21.2\u2009months, respectively) and radiographic unions were observed at an average of 19.6\u2009weeks (range, 12\u201328\u2009weeks). The patients were evaluated immediately after surgery, as well as 6\u2009weeks, 3\u2009months, 6\u2009months, 1\u2009year, and 2\u2009years postoperatively. Of the 49 patients, 38 had good reduction qualities (75.5%), 9 acceptable (18.3%), and 3 poor (6.1%). Radiographic union was confirmed in all fractures at an average of 19.6\u2009weeks (range, 12\u201328\u2009weeks). The mean Harris hip score was 84.9 (range, 65\u201399): excellent in 9 patients (18.36%), good in 30 (61.22%), medium in 8 (16.32%), and poor in 2 (4.08%). Slight persistent pain occurred in 3 patients, but these patients could still walk with the help of a cane. Two patients had symptoms of excessive telescoping.
