Project Description
EUROSCREW® PLA & PLA/TCP
Bioabsorbable Screw for Ligamentoplasty Surgeries
The EUROSCREW® range of interference screws offers a complete assortment of screws and instruments for securely fastening transplants in ACL reconstruction techniques.
EUROSCREW® is stable for 8-10 months post-operatively, ensuring good healing and simplifying any future revision. It is then gradually hydrolysed by water from the tissues and totally replaced by healthy bone after 24 months.
The presence of TCP into the PLA matrix keeps a neutral pH of the material by buffer effect during the degradation time and reduces the risk of inflammation. β-TCP is also an osteoconductive material which promotes bone ingrowth.
EUROSCREW® PLA is radiotransparent and EUROSCREW® PLA/TCP is radiopaque.
ADVANTAGES
- Resorbable
- High torsion strength
- Self-tapping
- PLA or PLA/ TCP
- Osteoconductive (PLA/ TCP)
- Design
- Controlled degradation
- Simple to use
- Mechanical strength
The EUROSCREW® range is suitable for all current techniques. You will find the most appropriate solution for your needs whatever the chosen technique or anatomical requirements of the patient. EUROSCREW® fastens the ligament transplant as well as bone-tendon-bone transplants, both to the tibia and the femur.
EUROSCREW® has a conical tip with self-tapping thread so that it bites efficiently as soon as it is inserted.
The subsequent threads are rounded to protect the transplant from any risk of shear. The thread depth maximises resistance against tearing.
EUROSCREW® 24 mm long screws have a hemispherical head, while 30 mm or 35 mm long screws have a flat head.
The hemispherical head will not lacerate the transplant at the femoral tunnel. The flat head will allow it to be screwed deeply at the tibial tunnel.
1. MECHANICAL PROPERTIES
EUROSCREW® has been tested and compared to screws already available on the market.
The larger the diameter of the screw, the greater its torsional strength. We therefore chose to compare 7 mm diameter screws (the weakest).
It can be seen that EUROSCREW® achieves equivalent torque to the ARTHREX screw.
2. RESORPTION
EUROSCREW PLA® is made of 100% polylactide. This PLA follows degradation kinetics controlled by the initial molar mass. The higher this mass, the longer the resorption time.
EUROSCREW PLA/TCP® is made of 70% polylactide (PLA) and 30% β-tricalcium phosphate (TCP). EUROSCREW PLA/TCP® is stable for 6 months post-operatively, ensuring good healing and simplifying any future revision. It is then gradually bio-absorbed by the bone cells and totally replaced by healthy bone after 24 months.
EUROSCREW® is manufactured under conditions that ensure an identical initial molar mass for each screw. Surroundings biological factor of patients, the screws will all degrade at the same speed.
EUROSCREW® SET is a complete instrument set for drilling and precise positioning of femoral and tibial tunnels during ACL reconstruction.
EUROSCREW® SET comprises:
- An open stripper.
- A calibration plate for the graft.
- A precise rigid tibial guide for one-handed use.
- Two femoral guides with an offset of 1 mm to 3 mm to optimise placement of the femoral tunnel during a gracilis tendon reconstruction.
- Two Ø2.4 mm eyed pins to guide drilling and positioning the graft
- A set of drill bits and cannulated reamers for drilling the tunnels.
- Two Ø1.2 mm pins to guide placement of the EUROSCREW and EUROSCREW TCP interference screws.
- A conformator set to preform the tunnels before passing through the EUROSCREW® and EUROSCREW® TCP interference screws.
- A screwdriver to insert the EUROSCREW® and EUROSCREW® TCP interference screws.
