Subtrochanteric Femoral Fractures After SIGN Locking Intramedullary Nails

Prevention Strategies for Intraoperative Complications

  • Thorough preoperative assessment of the entire femur is essential to identify any proximal lesions that could lead to implant failure, as recommended by Praxis Medical Insights 1
  • Adequate preoperative imaging prevents missed pathology and suboptimal implant selection, as recommended by Praxis Medical Insights 1
  • External rotation of the intramedullary nail during insertion can reduce the risk of malreduction in bowed femurs, according to the American Academy of Orthopaedic Surgeons 2

Context: Atypical Femur Fractures

  • Atypical femur fracture incidence is 55 per 100,000 person-years in bisphosphonate users versus 1 per 100,000 in bisphosphonate-naive patients, as reported by the American Academy of Orthopaedic Surgeons 2
