PFNA Femoral Gamma Interlocking Intramedullary Nail is composed of high-strength titanium alloy and is divided into standard type and lengthened type. Consists of PFNA Femoral Gamma Interlocking Intramedullary Nail, Locking Nail, Blade Nail and Locking Tail Cap. The length of the tail cap is designed to facilitate the doctor's operation. The PFNA femoral gamma interlocking intramedullary nail is designed with a declination angle of 5 degrees, allowing insertion from the apex of the greater trochanter, ideal stress distribution, elastic tip and groove design for easy insertion of PFNA, avoiding local stress concentration at the distal end. At present, PFNA products are widely used in the operation of proximal femoral fractures such as intertrochanteric fractures and greater trochanteric fractures. They have been vigorously promoted due to their excellent straight characteristics with less bleeding, small incision and short operation time. Currently, 80,000 PFNA surgeries are performed each year in China.
