Project Description

EUROSCREW® PLA & PLA/TCP

Bioabsorbable interference screw for ACL surgery

EUROSCREW® is an absorbable interference screw used for knee anterior cruciate ligament repair.
This specifically designed screw is suitable for fixation of both bone-tendon-bone grafts and soft tissue grafts.

EUROSCREW® and EUROSCREW® TCP 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.

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® and EUROSCREW® TCP are radiotransparent.

ADVANTAGES

  • Resorbable
  • High torsion strength
  • Self-tapping
  • PLA  or PLA/ TCP
  • Osteoconductive (PLA/ TCP)
  • Design
  • Controlled degradation
  • Simple to use
  • Mechanical strength

EUROSCREW® screws are recommended for fixing bone-tendon-bone grafts or soft tissue grafts during operations to reconstruct anterior crossed ligaments.

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® has an accessory to ensure a proper implantation.

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 screwdriver to insert the EUROSCREW®  and EUROSCREW®  TCP interference screws.

EUROSCREW PLA® interference screws are available in 8 different sizes, 5 diameters and 3 lengths.
Screws 24 mm long have a hemispherical head and are ideal for femoral attachment. Screws 30 mm and 35mm long have a flat head and are ideal for tibial attachment.
