The TITAN 3D Wedge System builds on Paragon 28's portfolio of osteotomy wedges and uses the same patented shapes as the PRESERVE Evans and Cotton Wedges. These porous titanium wedges offer surgeons an alternative to autograft and allograft bone.
The TITAN 3D Wedges have an open geometry with a three-dimensional scaffold that allows for blood entry, bone through growth, and the incorporation of biologics if used. Each wedge has a central opening which allows for passage of a 3.5 or 4.0mm screw across the osteotomy to help increase stability of the construct. In order to ensure accurate and consistent placement of this crossing screw, both wedge families leverage the patented PRECISION GUIDE System. Unlike many competitive implants, Titan 3D Wedges do not require the use of an ancillary surface plate. To increase the coefficient of friction and minimize the chance of implant expulsion, the TITAN 3D wedges are built with spikes which interface with bony surfaces. To facilitate accurate implantation, the system includes product specific inserters which thread onto the back of each wedge and have a strike plate to aid in final seating. The system also includes resection guides which limit excessive bone removal if explanation is required.
Paragon 28 is grateful for the significant contributions Dr. Thomas Chang, DPM Sutter Health, Santa Rosa, Calif., made as surgeon designer of this system.
