The incidence of intertrochanteric fractures is rapidly increasing. Intertan nail and Gamma3 nail are the common new generation of intramedullary fixations for the treatment of intertrochanteric fractures. In this study, we compared the results of unstable intertrochanteric fractures treated with Intertan nail and Gamma3 nail. From January 2011 to August 2014, 100 patients meeting inclusion criteria were enrolled and randomly divided into Intertan group and Gamma3 group. Each group comprised 50

Preoperative variables included age, gender , fracture classification, preoperative Harris hip score (HHS), American Society of Anesthesiologists (ASA) score, duration of admission to surgery. The blood routine test at the day before operation and the first day after operation , the time required for the closed reduction, X-rayed times, operative time, estimated intraoperative blood loss, the number of transfused patients and units, time to mobilization, were recorded and analyzed. On the second postoperative day, anteroposterior and lateral radiographs of the affected hip were obtained to assess fracture reduction and measure the tip-apex distance (TAD). Patients were followed at 1, 2, 3, 4, 6, and 12 months after surgery. Operative complications, femoral neck shortening, fracture healing time, HHS were used to evaluate the outcome. Preoperative data were similar between the two groups. Operative time was significantly longer and intra-operative blood loss was significantly larger in the Gamma3 group than that in the Intertan group. The decrease in hemoglobin, the number of transfused patients and units were also statistically bigger in Gamma3 group than that in Intertan group. No significant difference was found in X-rayed times, reduction results, TAD, time to mobilization, operative complications, femoral neck shortening, fracture healing time, HHS. Both Intertan nail and Gamma3 nail are effective for surgical treatment of intertrochanteric fractures. Intertan nail has the advantage of shorter operative time and less blood loss.
