The Optimal Distal Fixation Choice
The Austofix S2 nail overcomes the disadvantage of other supracondylar nails by maximising distal fixation. Ideal for use with osteoporotic bone, it’s leading design advantages have been the result of solid research and surgical expertise.
S2 Nail Advantages
- Angle Stable
- Bio-mechanically superior to locked plates
- Lower moment arm
- Better proximal fixation
- Multi-planar Locking
- Screws engages the posterior condyles within 21mm of the end of the nail where bone quality is better
- Condylar screws lock into the nail due to low clearance fit
- More distal than most other SCN’s
- Condylar screws are placed to provide optimal support for condylar fragments
- The most distal screw is just 10mm from the nail end for maximum subchondral support
- Superior biomechanical qualities mean S2 patients can be mobilised the next day
- Important for elderly, smokers and obese patients etc.
- Not generally possible with a locking plate
Anatomical Design
- Conforms to the anatomy of the Distal Femur
- Distal diameter of 13mm tapering to 11mm proximal
- Allows insertion in the presence of TKR.
- Anterior-Posterior bow in nails 240mm and over
- Angle differs according to the length of the nail ensuring no stress risers are caused
- Superior Distal Screw Placement
- Provides superior support for supracondylar fracture types.
- Shorter bending moment on locking screws.
Screw System
Austofix threaded shaft screws lock into the nail via a true a locking mechanism that prevents screw back-out and maximises fixation.
- Lag screw design provides controlled compression
- Can be used in conjunction with washers for added compression and stability
