Core Tip

Core Tip: There are few studies comparing the clinical outcomes and radiographic results in elderly patients with pertrochanteric femoral fracture (PFF) receiving proximal femoral nail antirotation (PFNA) and those receiving the previous-generation proximal femoral nail. PFNA using a helical blade demonstrated better clinical and radiographic outcomes in terms of clinical score, sliding distance and cutout rate in elderly patients with PFF.
