The Ogmend® Implant consists of a sterile, single-use, permanently implanted sleeve intended to provide supplemental fixation to restore stability when the screw-to-bone interface becomes mechanically compromised. The Ogmend® Implant is manufactured from PET fibers and provides a helically braided structure that is captured by a screw when the screw is advanced during placement. When inserted into a prepared bone hole, the Ogmend® Implant is designed to use the principles of interference fit, surface area contact, and pressure distribution to secure the screw to the bone and achieve stability at the screw-to-bone interface allowing for subsequent tissue ingrowth to the screw root through the open, braided, mesh architecture. The Medum Ogmend® has an inner diameter of 6.5mm and an outer diameter of 7.5mm and can be used with screws ranging in diameter from 3.5mm to 6.5mm. Ogmend® Medium Sleeve is supplied at a length of 100mm and is cut intra-operatively to the appropriate length.
An implantable tube-like sleeve intended to provide a secure fixing for a bone screw (e.g. orthopaedic, spinal) which has lost purchase due to screw loosening, back out, or breakage. It is inserted into the screw hole so that when a screw is inserted, a mechanical wedge is created as it is tightened. The sleeve is made of a non-bioabsorbable polymer and sleeve size is adjusted/configured intraoperatively. Disposable devices associated with implantation may be supplied with the sleeve.
