The aim of this study is to compare the effects and complications of InterTAN nail versus Dynamic Hip Screw (DHS) in treatment of femoral intertrochanteric fractures. Between January 2006 and December 2013, a total of 75 patients with femoral intertrochanteric fractures were retrospectively reviewed. There were 16 cases of type A1, 51 cases of type A2, and 8 cases of type A3. 37 patients treated with InterTAN nail, and 38 with DHS. The clinic data of surgical trauma, postoperative function and complications were statistically compared in this study. This results indicated that 31 cases by InterTAN and 30 cases by DHS had obtained follow-up with mean time (11 ± 5.6) months. Operative time of InterTAN group is (23.1 ± 9.2) min, and of DHS group is (55.2 ± 14.5) min (P < 0.05). Intra-operative active blood loss is (70.1 ± 30.7) ml in InterTAN group, and (205.7 ± 40.7) ml in DHS group (P < 0.05). Fluoroscopy frequency of InterTAN group is (16.3 ± 4.4) times, and of DHS group is (25.1 ± 3.1) times (P < 0.05). Complications occurred in 3 cases (9.7%) in InterTAN group compared 6 cases (20%) in DHS group (P < 0.05). Two cases had hip varus in InterTAN group, and three cases in DHS group. One case had deep venous thrombosis (DVT) in InterTAN group, and one case in DHS group. In conclusion, InterTAN significantly reduce the operative time, fluoroscopy frequency, intra-operative active blood loss and postoperative complications. The InterTAN technical features make it applicable to the aged patient with variety of medical basic diseases and cases of osteoporotic and unstable fracture types.

Association Between Nail Type and Aseptic Revision Risk After Cephalomedullary Nailing for Hip Fracture.

Surgical Outcomes and Analysis Department, Kaiser Permanente, San Diego, California.
Background: Although the majority of intertrochanteric femoral fractures in the United States are now treated with cephalomedullary nailing, it remains uncertain whether differences in clinical performance by nail type exist. The purpose of this study was to compare the aseptic revision rates associated with the 3 most commonly utilized cephalomedullary nails in the United States today: the Gamma nail (Stryker), the INTERTAN (Smith+Nephew), and the Trochanteric Fixation Nail/Trochanteric Fixation Nail Advanced (TFN/TFNA; DePuy Synthes).
Methods: Using an integrated health-care system's hip fracture registry, patients ≥60 years of age who were treated with 1 of these 3 commonly used cephalomedullary nail devices were identified.

Background: This study aimed to analyze the files of patients treated using PFN-A or INTERTAN intramedullary nails to reveal additional superiorities or disadvantageous factors for selecting the better intramedullary fixation method in patients presenting with intertrochanteric femur fractures.
Methods: In this retrospective study, the files of the patients who were operated on for intertrochanteric femur fractures using intramedullary fixation methods between September 2010 and June 2015 in the Orthopedics and Traumatology Clinic, Çukurova University Faculty of Medicine, were reviewed. The data including age, gender, chronic diseases, causes of fractures, fracture classification based on Arbeitsgemeinschaft für Osteosynthesefragen (AO), the nail type (long or short), the interval between trauma and surgery, duration of anesthesia and surgery, hospitalization duration, amount of blood transfusion, the Tip-Apex Distance (TAD) in postoperative radiographs, functional outcomes according to Harris Hip Score (HHS) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), postoperative complications, need for revision, and mortality was noted.

Background: Subtrochanteric proximal femoral fractures are generally treated with cephalomedullary nail fixation. We aimed to compare outcomes of subtrochanteric fracture fixation using a single lag screw (Gamma3 nail, GN) or dual lag screw (INTERTAN nail, IN) device.
Methods: The primary outcome measure was mechanical failure, defined as lag screw cut-out or back-out, nail breakage, or peri-implant fracture.

Objective: Given the recent application of two new types of intramedullary nail devices in the treatment of comminuted femoral intertrochanteric fractures (CFIFs), there is still a lack of deep understanding and comparative evaluation of their biomechanical properties. Therefore, this study aims to systematically compare the advantages and disadvantages of these two new devices with traditional proximal femoral nail antirotation (PFNA) and InterTan nails in the fixation of CFIFs through finite element analysis.
Methods: Based on the validated finite element model, this study constructed an accurate CFIFs model.
