The aim of the current study was to compare the implant failure rates of these two implants in 31A1 type trochanteric femoral fractures.<h4>Materials and methods</h4>A single-centre observational cohort study was conducted in the Hip Fracture Unit of a multicentre level 1 trauma teaching hospital between December 2016 and October 2018. Patients with an AO/OTA type 31A1 fracture were included. Pathological fractures, bilateral fractures, high-energy traumas and patients younger than 18 years of age were excluded. Surgery was performed using either a DHS or PFNA. Both were used routinely for stable trochanteric fractures, and allocation was decided by the surgeon peArchives of orthopaedic and trauma surgery1459-1467https://www.ebi.ac.uk/biostudies/studies/S-EPMC9217838biostudies-literatureHigh risks of failure observed for A1 trochanteric femoral fractures treated with a DHS compared to the PFNA in a prospective observational cohort study.PMC9217838Niggebrugge AHPvan der Sijp MPLMeylaerts SAVerhage SMSchipper IBde Groot Mdu Pre KJfalseHigh risks of failure observed for A1 trochanteric femoral fractures treated with a DHS compared to the PFNA in a prospective observational cohort study.<h4>Introduction</h4>Both the DHS and the PFNA are common and well-studied treatment options for stable trochanteric fractures.
