PROXIMAL FEMORAL NAIL ANTIROTATION
PFNA 股骨近端防旋髓内钉用于治疗股骨转子间、转子下等不稳定骨折，采用螺旋叶片结构强化抗旋能力
PFNA (Proximal Femoral Nail Antirotation) is indicated for unstable intertrochanteric and subtrochanteric fractures, with helical blade structure for enhanced antirotation performance.
Anti-rotation mechanism enhances stability of femoral head-neck fragments
Anti-rotation mechanism enhances stability of femoral head-neck fragments
Intertrochanteric fractures (unstable)
Subtrochanteric fractures
Osteoporotic proximal femoral fractures
Helical blade reduces cut-out risk, suitable for osteoporotic patients
Minimally invasive insertion shortens operative time
Standard and long PFNA
Multiple helical blade diameters
