BIOINTRAFIX® Tibial Sheath and Screw

Division: Mitek Sports Medicine
Category: ACL Reconstruction

The BIOINTRAFIX® ACL Fixation System is designed to provide soft tissue tibial fixation for ACL reconstruction. BIOINTRAFIX System, with its unique patented sheath and screw implant design offers a novel technique to achieve secure tibial fixation. BIOINTRAFIX System is made from BIOCRYL® Material, a bio-absorbable material that contains osteoconductive TCP. 

Indications for Use

The BIOINTRAFIX System Tibial Tapered Screws and Sheaths are indicated for fixation of soft tissue grafts during cruciate ligament reconstruction.

Features & Benefits

Features Benefits
ß-TCP Bioabsorbable Material  The BIO-INTRAFIX Screw and Sheath are molded from a composite of PLA and osteoconductive TCP (Tricalcium Phosphate).1 TCP provides the osteoconductive bioceramic material necessary to promote bone growth into the sheath and screw. ß-TCP has been shown to dissolve and reabsorb more quickly than HAp (Hydroxyapatite). Invivo studies show that ß-TCP forms a strong bone-implant interface, bonding to bone and exhibiting osteoconductive characteristics.1
Enhanced bone-to-graft contact The patented screw and sheath design enhances bone-to-graft contact and strength through:
  • Concentric screw placement
  • 360° graft placement
  • Improved engagement 
Strength of fixation Tested in human cadaver bone, the BIO-INTRAFIX System demonstrated excellent fixation, with >1000N pull-out strength1, and allows rigid absorbable material to perform like a flexible plastic sheath. Tested in an independent study (against five other tibial soft tissue fixation systems), INTRAFIX® Fixation System demonstrated the highest strength and stiffness with the lowest graft displacement.2
