Impact of limb positioning on femoral nerve tension during minimally invasive anterolateral approach in total hip arthroplasty: a cadaveric study

Key Points

• This research aims to examine how limb positioning affects femoral nerve tension during hip surgery.
• Used cadaveric specimens to analyze limb positioning effects
• Measured changes in femoral nerve tension during different stages of surgery
• Compared results with modified Watson-Jones approach
• Femoral nerve tension increased by over 70% with hip dislocation to femur elevation
• Tension was notably greater using the modified Watson-Jones approach
• Findings suggest the need for adjustments in surgical techniques to minimize nerve tension
