Purpose: Hip fractures are a growing concern for healthy systems worldwide. Several fixation modalities have been developed for the fixation of AO type 31-A1/A2/A3 fractures. The TFN-AdvancedTM Proximal Nail System (TFNA) is a novel fixation device that aims to build on success of previous generation nails. Currently, there is a paucity of literature regarding the outcomes of this implant. The aim of this study was to present our experience using the TFNA implant over a 2-year minimum follow-up. Methods: We retrospectively reviewed patients above the age of 65 who underwent closed reduction and internal fixation (CRIF) for AO type 31-A1/A2/A3 intertrochanteric fractures, with the TFNA nail between January 2017 and June 2018. The minimum follow-up time in our study was 2 years. Radiological evaluation was performed during follow up visits to evaluate for post-operative complications. Results: Following exclusions, the final study population consisted of 100 patients. The mean follow-up was 30.8 months (range 24–44, SD 5.1). During the follow-up period, 6% of the patients (n=6) experienced orthopedic complications. The rate of peri-prosthetic fracture in our study was 2% (n=2), the rate of peri-prosthetic infection was 2% (n=2) and the cut-out rate was 1% (n=1). No cases of mal-union or non-union were observed. Revisions were required in 4% of patients (n=4). Conclusion: The low rates of complications reported in our study support the implementation of TFN-A as a fixation device for AO type 31-A1/A2/A3 intertrochanteric fractures undergoing CRIF. Additional follow-up is required in the long-term.
