Comparison of the efficacy of PFNA and InterTAN intramedullary nail in the treatment of unstable intertrochanteric femoral fractures in the elderly

While both techniques demonstrated comparable long-term outcomes, PFNA may offer advantages in surgical efficiency and blood loss reduction, whereas InterTAN showed improved early postoperative outcomes regarding weight-bearing and initial pain management. The choice between techniques should consider patient-specific factors and surgical priorities. Further prospective studies are warranted to establish stronger clinical guidance.
