Introduction  \nFemoral neck fractures in patients under 50 years of age are relatively rare, comprising 2% to 3% of all neck of femur (NOF) fractures.1 Most of these injuries are associated with high-energy trauma, often related to motor vehicle accidents or sports injuries.2 Managing these fractures poses unique challenges due to anatomical and biomechanical complexities, especially in younger patients where preserving the natural hip joint and function is paramount.  \nA significant concern in treating femoral neck fractures is the risk of complications such as avascular necrosis (AVN) and nonunion,  \nThe authors have no conflicts of interest to disclose.  \na Joondalup Health Campus, Joondalup, WA, Australia, b Curtin University Medical School, Bentley, WA, Australia, c Perth Orthopaedic Specialist Centre, St John of God Hospital Mt Lawley, Mt Lawley, Australia.  \n*Corresponding author.

AVN can occur in 12% to 47% of NOF fractures after internal fixation, depending on fracture type, patient factors, and surgical technique.3 Nonunion rates can also be as high as 10% to 30% in displaced fractures.4 In younger patients, preserving joint integrity and achieving stable, anatomic reduction is crucial due to greater long-term functional demands. The performance of a bone–implant construct is known to depend on implant material, structural properties, and bone q","cbCaij5szfJ5ZO8a","https://ap.wps.com/l/cbCaij5szfJ5ZO8a","pdf",1112871,"English","# Abstract\n# 1.
