There May Be a Right Side? Clockwise Torque Results in Higher Reoperation Rates in Left-Sided Femur Fractures in 20,122 Patients

•This study showed a higher risk of reoperation for left-sided compared to right-sided proximal femur fractures after CMN in a large sample size.•The results might substantiate the hypothesis that clockwise rotation during implant insertion and weightbearing lead to higher reoperation rates for left-sided fractures.•Research should focus on planning large size long-term follow-up studies identifying reoperation rates due to implant failure comparing both sides.
