Clinical Indications in Orthopedic Trauma The PFNA2 helical blade is indicated for the stabilization and internal fixation of extracapsular and proximal femoral fractures:
-
Intertrochanteric Fractures: 31-A1 (stable two-part) and 31-A2 (unstable multi-fragmentary) fractures with posteromedial wall comminution.
-
Pertrochanteric & High Subtrochanteric Fractures: Fractures with extension into the femoral shaft treated with long PFNA2 constructs.
-
Reverse Obliquity Fractures: Transverse and shear intertrochanteric patterns (AO/OTA 31-A3) that risk severe medial translation.
-
Geriatric Osteoporotic Fractures: Fragility hip fractures where conventional threaded lag screws fail to achieve dependable purchase or risk early migration.
-
Pathological Trochanteric Fractures: Fixation of structural metastatic lesions or impending fractures requiring rapid load-sharing stabilization.
