Bone grafting is frequently used to assist in reconstruction of bone defects following limb salvage procedures in tumor surgery. These defects can be large and require the use of bulk allograft and/or significant amounts of particulate graft material. This article reports a clinic's preliminary results with a bone graft containment material that serves as an artificial periosteum. This radiographic review evaluates the material's ability to prevent migration of bone graft and ascertain progressive callus formation. Early results have been encouraging.
