CONMED Corporation's (NASDAQ: CNMD) CONMED Linvatec arthroscopy unit today announced the release of new sizes of its Matryx™ Biocomposite Interference Screw. These new screws represent the latest advance in biocomposite material technology that allows CONMED Linvatec to produce the smallest Biocomposite Interference screw available on the market today for primary fixation of ACL and PCL grafts. The Company will debut the product at the Fall Arthroscopy Association of North America (AANA) meeting in Palm Springs, CA, which takes place November 19-21, 2009.
Interference screw fixation is frequently used to attach replacement ligaments in tunnels drilled for anterior and posterior cruciate ligament reconstruction. The placement of the screw in the boney tunnel with the ligament results in compression of the ligament against the boney surface of the tunnel. Such compression allows the tissue to be held in place and provides for the integration of the replacement ligament with the bone via natural healing pathways. The Matryx biocomposite screw encourages bone formation due to the presence of the bone pre-cursor Beta TriCalcium Phosphate, resulting in strong bone reconstruction and integration of the replacement ligament.
Matryx interference screws are indicated for soft tissue fixation in ACL and PCL reconstructions. With the new smaller sizes, in conjunction with the new Bullseye™ Anatomic Cruciate Reconstruction System, CONMED Linvatec can now provide a complete anatomic solution for cruciate repairs. The new smaller Matryx screws will be used extensively in double bundle anatomic reconstructions where two small bone tunnels are drilled for the reconstruction of the ligament. The existing larger Matryx sizes (7-11mm) are indicated for soft-tissue and BTB graft fixation in ACL and PCL reconstructions.
