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
