Osteotomies are procedures in which bone is cut and then re-aligned, often with new bone placed as a wedge to secure the new position. The Cotton osteotomy involves the medial cuneiform and is used to correct rotational deformities of the forefoot. The Evans osteotomy is a lengthening procedure for the calcaneus, used most commonly for treating flatfeet. Novastep’s biofit™ Wedge System allows for more efficient procedures by eliminating some of the measuring and shaping of the graft material that is frequently required.
Size Specific Trials
The biofit™ Wedge System includes a compactly organized, ergonomically designed trials instrument module. The size specific trials provide a method of assessing osteotomy spaces to assist in the selection of appropriate biofit™ allograft wedge implant.
The biofit™ instrument module is fully compatible with all Novastep cleanSTART® instrumentation trays and may be easily interchanged with other instrument modules or added to them within the trays. The cleanSTART® trays feature intuitive layouts, interchangeable modules, light weight construction and space saving designs that eliminate the need for multiple, bulky containers.
Pre-Shaped Bone Wedges
Biofit™ size specific allograft wedges are available off the shelf, for immediate use in Evans and Cotton osteotomies. Intraoperative management of the desired osteotomy is greatly simplified and choosing the correct graft size is quick; facilitating precise corrections, fracture reductions, joint fusions and bone void fills with minimal prep times.
The biofit™ wedge implants are aseptically processed from human cancellous bone, through bioSTART® Tissue Repair Process to provide an osteoconductive scaffolding matrix that permits bony in-growth. The allografts are stored at ambient temperature with a five-year shelf-life.
