Project Description

EUROSCREW® NG & TCP NG

Bioabsorbable Screw for Ligamentoplasty Surgeries

EUROSCREW® NG & TCP NG is a bioabsorbable cannulated screw specially designed for ligamentoplasty surgical techniques like anterior/posterior cruciate ligament reconstructions, reinsertion of the long-head of the biceps tendon or ankle ligaments.

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

EUROSCREW® NG offers a complete range of screws and tools that ensure a secure fixation of the transplants.

The interference screws EUROSCREW® NG are available in 9 references, including 6 diameters and 4 lengths suitable for current ligamentoplasty techniques.

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.

These screws EUROSCREW® NG & TCP NG  are mechanically stable for respectively 8-10 months and 6 months post-operative; this allows a good rehabilitation. Then they are slowly hydrolyzed by water from surrounding tissues and fully replaced by neo-bone after 24 months.

ADVANTAGES

  • Resorbable
  • High torsion strength
  • Self-tapping
  • Double Thread – Fast screwing
  • Flat Head
  • Controlled degradation
EUROSCREW® NG & NG TCP  is suitable for current ligamentoplasty techniques (bone-tendon-bone or soft tissues grafts in femoral or tibial tunnels).
HIGH TORQUE RESISTANCE
The Range EUROSCREW® NG was 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.

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. As a result, improved insertion preserves graft’s integrity.

FLAT HEAD
A flat head prevents tissue’s friction at the bone surface after implantation. The screw can be inserted as far as needed; this is particularly suitable for tibial 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.
