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.

EUROSCREW®  NG and EUROSCREW®  NG TCP are available in several sizes :

6mm L 20mm / 7 mm L 24 mm / 8 mm L 24 mm / 9 mm L 24 mm / 7 mm L 30 mm / 8 mm L 30 mm / 9 mm L 30 mm / 10 mm L 30 mm / 11 mm L 35 mm

EUROSCREW® NG has an accessory : EUROSCREW® NG INSTRUMENTATION SET to ensure a proper implantation.

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 screwdriver to insert the EUROSCREW® NG interference screws.
