Project Description

EUROSCREW® NG & TCP NG

Bioabsorbable interference screw For Ligamentoplasty Surgery

EUROSCREW® NG are bioabsorbable cannulated screws specially designed for ligamentoplasty surgical procedures.
EUROSCREW® NG & TCP NG offer a complete range of screws and tools to ensure a secure fixation of the transplants.

The screws are suitable for current ligamentoplasty techniques (bone-tendon-bone or soft tissues grafts in femoral or tibial tunnels).

As the range EUROSCREW®, EUROSCREW® NG range is available in 2 materials : 100% PLA and 70% PLA + 30% β-TCP

EUROSCREW® TCP NG is radiopaque.

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® NG and EUROSCREW® TCP NG are mechanically stable for 8-10 months. Bioabsorption kinetic is tailored to start at the end of natural bone healing. Complete absorption of the screw is observed within a maximum of 4 years.

ADVANTAGES

  • Resorbable
  • High torsion strength
  • Self-tapping
  • Double Thread – Fast screwing
  • Flat Head
  • Controlled degradation

EUROSCREW® NG  screws are recommended for ligament attachment in knee anterior cruciate ligament or ankle lateral ligament reconstructions.

EUROSCREW® NG TCP screws are recommended for ligament attachment in knee anterior cruciate ligament reconstructions.

HIGH TORQUE RESISTANCE
EUROSCREW®  NG are designed to reduce the risk of breakage with a better distribution of torque. The screws have a triangular inner cone which ensures perfect contact between the screwdriver and the screw. This contact allows transmission of torque in a compression mode and not in shearing mode. This increases the torque failure resistance of EUROSCREW®  NG.

SELF-TAPPING
A conical tip and specific threads avoid the need to tap even for TCP version.


SPECIAL INTERNAL CONFIGURATION
Internal design of the tip avoids any contact between the screwdriver and soft tissues.

DOUBLE THREAD – FAST SCREWING
EUROSCREW® NG has a double thread that reduces the number of turns to introduce the screw into the pre-drilled tunnel.

EUROSCREW® NG has an accessory :

EUROSCREW® NG INSTRUMENTATION SET to ensure a proper implantation.

EUROSCREW® NG INSTRUMENTATION SET is a complete instrument set for drilling and precise positioning of femoral and tibial tunnels during ACL reconstruction.

EUROSCREW® NG INSTRUMENTATION 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® NG interference screws.
  • A conformator set to preform the tunnels before passing through the EUROSCREW® NG interference screws.
  •  A screwdriver to insert the EUROSCREW® NG interference screws.
