To clarify the anatomy of the femoral nerve and its variations, which influence the success of femoral nerve blocks.
Summarized anatomical, cadaveric, and imaging studies related to the femoral nerve.
Reviewed procedural techniques including landmark, nerve stimulator, and ultrasound-guided approaches.
Correlated ultrasound features with cadaveric findings for optimal needle placement.
Ultrasound guidance showed improved accuracy and reduced vascular puncture rates compared to traditional methods.
Continuous catheter methods and proper anesthetic selection lead to improved outcomes and reduced local anesthetic volumes.
Detailed awareness of the femoral nerve's anatomy reduces the risk of complications like nerve injury and hematoma.
