DePuy Mitek Launches BIO-INTRAFIX(TM), the Latest Innovation in ACL Repair -- Soft Tissue Tibial Fixation
BIO-INTRAFIX COMBINES THE RELIABILITY OF THE INTRAFIX(TM) SYSTEM WITH THE
ADDED BENEFIT OF BIO-ABSORBABILITY
NORWOOD, Mass., June 24 /PRNewswire/ -- DePuy Mitek, Inc., a leading manufacturer of surgical sports medicine devices, announced today the launch of the BIO-INTRAFIX Soft Tissue Tibial Fixation System. BIO-INTRAFIX is the next-generation of soft tissue tibial fixation for Anterior Cruciate Ligament (ACL) repair; combining the proven success of the INTRAFIX system, DePuy Mitek's leading ACL repair product for over five years, with the bioabsorbable BIOCRYL(TM) material, comprised of osteoconductive TCP and bioabsorbable PLA. BIO-INTRAFIX was developed to address the growing trend in the use of soft tissue grafts in ACL repair procedures (replacing the torn ACL with a hamstring tendon graft harvested from the patient) as an alternative to the widely used bone-tendon-bone patella tendon repair. "In 1998, 20 - 30 percent of the ACL repair procedures I performed were done using soft tissue tibial fixation, today that number has increased to 80 percent," said John C. Richmond, M.D., Chairman of Orthopedics at New England Baptist Hospital in Boston, MA. "This increase is due in part to the benefits provided by the soft tissue procedure over the bone-tendon-bone procedure; including smaller incisions resulting in smaller scars, the potential for a shorter rehabilitation time, as well as less kneeling pain." The new BIO-INTRAFIX System was created based on DePuy Mitek's INTRAFIX System, which has a successful history of clinical use since 1999. The BIO- INTRAFIX system consists of two bioabsorbable (TCP/PLA) components: the expansion sheath, and the tapered screw; both molded from BIOCRYL material, a composite of PLA and osteoconductive TCP (Tricalcium Phosphate). * Both systems achieve fixation by placing the expansion sheath into the tibial tunnel between the soft tissue graft strands and then inserting the screw into the sheath. The system compresses the graft against the tunnel and due to the design of the expansion screw, engages the cortical wall at the distal end of the tunnel creating strong, rigid fixation. In one study, the BIO-INTRAFIX system produced pullout strength of 1067N (the amount of force it would take for a screw to pull out of bone), equivalent to/better than bone-tendon-bone results.* "I have been very impressed with BIO-INTRAFIX and I will continue using it for my soft tissue tibial fixation procedures," said Dr. Joseph H. Sklar, M.D., from New England Orthopedic Surgeons in Springfield, MA. BIO-INTRAFIX is indicated for fixation of soft tissue grafts during cruciate ligament reconstruction. The BIO-INTRAFIX screw is available in three sizes; 6-8 x 30mm, 7-9 x 30mm and 8-10 x 30mm.
