Cayenne Medical Inc. has received FDA clearance for the iFix(TM) Interference Screw System for use in bone-tendon-bone ACL reconstruction procedures. These are the first FDA approved screws to hit the market that are made from polyetheretherketone (PEEK) plastic, which is radiolucent and highly biocompatible and has superior biomechanical strength. PEEK is a completely bio-inert material and, hence, screws made from this material do not result in foreign body reactions in patients.
