The TITAN 3-D™ Wedge System offers a porous titanium wedge that provides an alternative to allograft/autograft bone for an Evans Calcaneal Osteotomy for lateral column lengthening. The TITAN 3-D™ Wedge System builds on Paragon 28®’s portfolio of osteotomy wedges and uses the same patented shapes as the PRESERVE™ Evans Wedges.
The TITAN 3-D™ 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 4.0 mm 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. To increase the coefficient of friction and minimize the chance of implant expulsion, the TITAN 3-D™ 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.
