Combines the principles of a compression hip screw with an Intramedullary nail
Simple. Anatomic. Versatile.
The AFFIXUS® Hip Fracture Nail System designed to provide an efficient, practical solution for treating a wide range of proximal femoral fractures.
- Hip and Femur
- Intramedullary Nailing
The system combines the principles of a compression hip screw with the biomechanical advantage of an intramedullary nail. By combining a proximal 1.8M radius of curvature with a 3 degree distal bend, the resultant bow is comparable to a proximal 1.5M radius of curvature with a minimal offset. This not only accommodates the anterior bow of the natural femur, but also is designed to help ease insertion through the proximal region and minimize the risk of penetrating the anterior cortex.
Goal post™ Technology
The Goal Post Technology is designed to facilitate visualization of the femoral neck on the lateral view in order to accurately place the guide pin for the lag screw. The anterior and posterior metal posts on the proximal aspect of the insertion jig allow for an unobstructed fluoroscopic view down to the base of the femoral neck and assist with fine tuning of the guide pin before it is fully seated in the femoral head.
Lag Screw Design
The lag screw was designed with a reverse buttress thread pattern, which is intended to provide subchondral support under load, while also helping minimize potential for “cut-out”. The lag screw has wide slots or grooves providing the surgeon approximately 15° of adjustment when tightening the set screw. Also, the lag screw has a shoulder which is intended to prevent medial migration.
Since the system offers two different nail angles, 125° and 130°: the system includes two easy to use jig assemblies that correspond to the neck angle of the implant. The jig assembly was also designed to include a jig tab. This jig tab mates with the implant nail slot to ensure both the targeting jig and implant neck shaft angle match. During use, if it is difficult to attach the nail to the jig assembly, it can simply be confirmed that the nail and jig assembly are identified with the same neck shaft angle.
On the proximal portion of the jig assembly, there are two holes, where a 3.2 mm guide pin can be placed. Under lateral fluoroscopy, this guide pin gives a visual indication to the potential starting point of the 3.2 mm guide pin.
The system includes two flexible instruments where flexibility makes sense. When preparing the femoral canal, a flexible entry reamer has been designed to help with the entry on larger patients. This reamer will bend to help gain proper entry into the femoral canal. Also, flexibility has been added to the jig bolt driver. This allows the surgeon to easily tighten down the jig bolt inside the jig assembly
This system includes a one piece compression wheel assembly that can be easily placed unto the lag screw driver by sliding the wheel device unto the lag screw driver without disassembling instrumentation. Rotate the compression wheel clockwise to compress the intertrochanteric component of the fracture.
Lag Screw Drill
The lag screw drill includes a pre-assembled depth stop device. After taking measurement of the lag screw, set the measurement length on the lag screw drill by pushing the side buttons and sliding the depth stop forward or backward to the desired measurement length. There is also a notch on the lag screw drill that is visible under fluoroscopy. This notch is a visual reference of 100 mm lag screw length.
