Proximal Femur : Fixion PF Nailing System |
|
| |
| |
|
|
 |
The Fixion Proximal Femur Nailing System is designed to treat proximal femur fractures. It combines an expandable nail for the femoral shaft with a dynamic expandable hip peg for stability within the femoral head. |
|
| |
|
|
| |
THE FIXION PF NAIL : |
|
|
Expanded within the medullary canal using saline solution. |
|
|
Inserted into the femoral canal in a reduced diameter and then expanded.
|
|
|
Bent to suit the anatomical curvature of the femur, and adapts to the contours and
shape of the medullary canal. |
|
|
Allows for perfect positioning within the canal and at the fracture site. |
|
|
Bone fixation is enhanced by four longitudinal bars.
|
|
|
Fixation to the cortex is achieved along the entire length of the nail. |
|
|
Available in short and long versions with a choice of 3 neck angles (125º, 130º, 135º). |
|

THE FIXION PF HIP PEG : |
|
| |
| |
| |
|
|
|
Expands within the femoral head using saline solution. |
|
|
Expansion condenses trabaecular bone to enhance fixation. |
|
|
Insertion only requires a drill diameter of 8mm. |
|
|
Tip with three bars, expands to up to 12mm in diameter to stabilize it within the femoral head. |
|
|
Proximal end oval shaped body adds to rotational stability. |
|
|
Hip peg is dynamic within the nail with optional limited sliding motion. |
|
|
Selection of lengths is available.
|
|
|
|
|
| |
|
|
| |
| |
Biomechanical studies have shown that: |
|
| |
| |
|
|
|
BMD increases around the Fixion Hip Peg after expansion and decreases around a standard lag screw after insertion. The increased bone density potentially contributes to a better fixation of the implant within the bone. |
|
|
The Fixion Hip Peg has 5 times higher torsional stability than a standard lag screw. |
|
|
The Fixion Hip Peg has similar pull-out strength to a standard Lag Screw. |

PRINCIPLES OF ORPERATION
: |
|
| |
| |
|
|
|
Minimally invasive procedure for proximal femoral fractures. |
|
|
Reduced diameter drill holes for nail and hip peg. |
|
|
No distal interlocking screws required. |
|
|
Reduced risk of infection.
|
|
|
Minimal exposure to fluoroscopy. |
|
|
Reduced operating time.
|
|
|
The PF nail and hip peg are provided sterile in a reduced diameter configuration.
|
|
|
The minimally invasive implantation procedure:
|
|
| |
- The PF nail is inserted using the insertion device.
|
|
| |
- Preparation for the hip peg is completed and the hip peg in inserted.
|
|
| |
- Both components are expanded with saline solution using a multi use pump. |

FixionŽ Femoral Nails |
|
| |
The Fixion Expandable Femoral Nailing System includes three types of nails: |
|
| |
|
Fixion IM Femoral Nail is indicated for diaphyseal fractures which are 5cm below the surgical neck, and 5cm proximal to the distal end of the medullary canal. These nails do not have any interlocking screws. |
|
Fixion IL Retrograde Femoral Nail is indicated for Proximal or Distal fractures. This nail is being locked proximally and its shaft is being expanded.
The Femoral nails have a standard 1.5m radius bending.
The Fixion Femoral nails are FDA cleared and CE marked. |
