PFNA. Proximal Femoral Nail PFNA Nail The anatomical design guarantees an optimal fit in the femur. The nail design has been well proven in over 450,000 cases performed with the PFN and PFNA. The PFNA has a medial-lateral angle of 6° This allows insertion at the tip of the greater Optimal stress distribution The flexible PFNA tip eases insertion and reduces stress on the bone at the tip of the Several distal locking options Static or dynamic locking can be per- formed via the aiming arm with PFNA standard, small and xs. The PFNA long additionally allows for secondary PFNA long 2 Synthes...

PFNA. Instrumentation. Easier guide wire positioning and insertion Correct positioning of the guide wire and finally the PFNA blade in the femoral head is crucial. The guide wire aiming device allows for AP orientation, which permits correction of the nail’s insertion depth prior to guide wire insertion. In the lateral view, rotation of the nail can be adjusted with the two orientation lines in the radiolucent insertion handle for PFNA. Intraoperative compression In good bone quality the new PFNA blades (0X.027.010S – 0X.027.021S and 0X.027.030S – 0X.027.041S) together with the compression...

PFNA. Augmentation. Fractures of the hip are the most common operatively treated fractures of the elderly (over the age of 70). The number of osteoporotic fractures is growing dramatically causing treatment to become an increasingly challenging issue. The PFNA Augmentation offers a unique system of controlled cement augmentation directly through the implant: – Higher number of cycles to cut-out and increased rotational stability in biomechanical testing – Simple and reproducible procedure through standardized surgical technique – Compatible with PFNA instrumentation and implants –...

AO Principles In 1958, the AO formulated four basic principles1, 2, which have become the guidelines for internal fixation in general, and intramedullary nailing in particular: Anatomic reduction Before inserting the nail, the reduction can be achieved manually or using a reduction table. A guide wire marks the prescribed path into the medullary canal and secures alignment of the fragments while the cannulated nail is being inserted over the wire. The nail insertion is generally monitored using x-rays. The nail is then locked proximally and distally to the bone fragments in order to hold...
