FH Orthopedics

CROSS lig interference screws are injected into the Duosorb® composite material, made of ß tricalcium phosphate ceramic and DL-polylactic acid.
This osteoconductive material, which has a mode of action that is similar to that of bone substitutes, has been specially designed :

• to make resorbable implants for intra-osseus areas;
• for use in conditions of high biomechanical resistance to flexion and compression constraints depending on the tricalcium phosphate load.
  

Indications

• Reconstruction of Anterior Cruciate Ligament (ACL);
• Reconstruction of Posterior Cruciate Ligament (PCL).
  

The concept

One screw CROSS lig for each ligamentoplasty technique (ACL and/or PCL) :

> Fixation of a “purely ligament” transplant of the hamstring tendon, quadricipital tendon type, etc…
> Fixation of a “bone-tendon-bone” transplant of the patellar tendon type.

Product characteristics

Duosorb® has been shown to have significant advantages in relation to materials made of pure Polylactic Acid.
In vitro and in vivo studies have shown that tricalcium phosphate:

• encourages the phenotype proliferation and expression of human osteogenic cells,
  
• decreases the inflammatory reaction – it is a bioactive material,
  
• encourages bone healing and resorption, in comparison with pure lactic acid polymers.
• 
  

It is a resorbable and radio-opaque material.
