Intercalary allografts
Figures 3A and 3B. Postoperative lateral radiographs showing a twenty-six-year-old woman who underwent osteosynthesis and received an 11-cm-long allograft that was implanted after radical resection of a low-grade osteosarcoma. (3A) Osteosynthesis was performed with use of a bridging plate. Two intramedullary bular allografts were used to augment the reconstruction. (3B) Both proximal and distal osteotomy lines had excellent consolidation at thirteen months postoperatively.
We evaluated sex, age, diagnosis, a ected bone, date of primary surgery, localization within bone level, and type of neo-adjuvant or adjuvant therapy. For reconstructions, we evaluated graft and xation type, addition of autografts, and length of the reconstruction. Allograft length was measured on conventional radiographs and was corrected for magni cation. We determined occurrence and time to complications. These determinations were performed separately for the lower extremity. Time to full weight-bearing was determined for lower-extremity reconstructions. Weight-bearing was allowed if the limb was considered stable, on the basis of imaging, physical examination, and duration since surgery. Study data were obtained from medical records, operation reports, and imaging, and
