BioSync® Anatomic Reconstruction Wedge

Biosync reconstructive wedges provide an alternative to allograft bone, most commonly for Evans and cotton osteotomies. Biosync is a 58% porous, three dimensional open cell titanium scaffold for bone and tissue ingrowth. The osteoconductive environment is designed to enhance potential for bone integration and attempts to minimize loss of correction made. Osteoblasts, osteoid, and angiogenesis have been shown in canine model at six weeks. Biosync has shown 75.4% bone and tissue ingrowth as early as 12 weeks. Evans wedge technique. An incision is made just below the sinus tarsi, extending laterally approximately three centimeters proximal to the calcaneocuboid joint, beginning 10 to 15mm proximal to the calcaneocuboid joint. Perform an osteotomy with an oscillating saw parallel to the calcaneocuboid joint. Leave medial cortex intact. Place 2.4mm or 1.6mm guidewire on each side of osteotomy and utilize a pin style distractor to provide controlled distraction and unobstructed access to the osteotomy site. Anatomical correction is performed by distracting the osteotomy site to the surgeon's desired reconstruction between 6.5 to 12mm. Evans wedges are available in three footprints 18 by 18, 20 by 20, and 22 by 22. Start with the smaller trials first and proceed exchanging colored trial inserters with thicker, larger trials. Evans wedges are offered in four correction thicknesses 6.5, eight, ten, and 12 millimeter. The central hole in the wedge may be packed using allograft, such as StimuBlast. Place inserter in center hole and rotate clockwise to attach BioSync wedge. After the wedge is flush, remove the pin distractor, K-wires, and wedge inserter by rotating counterclockwise. 2.4mm cortical screws may be used through the wedge for rotational control. Plate selection is based on BioSync, wedge utilized and patient anatomy. Cotton wedge technique. An incision is made dorsally over the medial cuneiform. The osteotomy is performed with a sagittal saw and gently opened with a stray osteotomy. The osteotomy may be held open with a pin style distractor or heart osteotomy. Distractor. Place 1.6mm pin on either side of cut. Place the distractor over 1.6mm. Pins and open. Anatomical correction is performed by distracting the osteotomy site to the surgeon's desired reconstruction, mirroring the shape of the medial cuneiform. Cotton wedges are available in two depths 16 and 20mm. Start with a smaller trials first and proceed exchanging colored trial inserters with thicker, larger trials. Cotton wedges are offered in four correction thicknesses 4.5, 5.5, 6.5, and 7.5mm. Attach the anatomical cotton BioSync reconstructive wedge by threading the wedge inserter into the center hole. Seat the implant into the osteotomy until flush with bone. After the wedge is flush, remove the pin distractor K-wires and wedge inserter by rotating counterclockwise. Ancillary fixation is required when using BioSync reconstructive wedges. The two hole straight plate or flat plate can be used for cotton osteotomy. The shape of the BioSync anatomic wedge mirrors the shape of the medial cuneiform so not to impinge soft tissue. Dorsal, medial, or middle cuneiform. Plantar laterally.
