Biomechanical Study of Gamma 2 Intramedullary Nail, PFNA, and INTERTAN in the Treatment of Elderly Intertrochanteric Fractures of the Femur

Peng Du

Abstract: A biomechanical comparison was conducted on the treatment of elderly intertrochanteric fracture models with Gamma 2 nail, PFNA, and INTERTAN using finite element method, providing a theoretical basis for the treatment of elderly intertrochanteric fractures. Construct a finite element model using numerical simulation to simulate the stress and strain mechanical distribution of the femur and intramedullary nails under axial loading after internal fixation of elderly intertrochanteric fractures. The peak stress-strain values in the intertrochanteric fracture area and intramedullary nail fixation under INTERTAN fixation are smaller than those in the other two fixation forms. Compared to intramedullary Gamma 2 nail and PFNA, INTERTAN has certain biomechanical advantages in treating elderly intertrochanteric fractures of the femur.
