Finite element biomechanics of novel intramedullary nails with varying diameters for intertrochanteric femoral fractures with lateral wall injury

PFTBN outperforms "II" PFBN and PFNA in load/shear resistance for intertrochanteric fractures with lateral wall injury, regardless of reaming. "II" PFBN also shows superior stability to PFNA. Reaming increases nail-bone contact, mitigating femoral stress concentration and refracture risk. Both PFTBN and "II" PFBN are reliable fixation options with promising clinical utility.

Abstract

PFTBN outperforms "II" PFBN and PFNA in load/shear resistance for intertrochanteric fractures with lateral wall injury, regardless of reaming. "II" PFBN also shows superior stability to PFNA. Reaming increases nail-bone contact, mitigating femoral stress concentration and refracture risk. Both PFTBN and "II" PFBN are reliable fixation options with promising clinical utility.
