The technique of cortical-cancellous iliac inlay-on-edge bone-grafting and the results obtained thirty-three patients have been presented. Union occurred in all patients, with protracted healing time in only two. This method of bone-grafting Provides a self-fixing osteogenic graft, or grafts, which contributes Stability to the site of delayed union or non-union. The technique has been used with and without internal fixation and is applicable where apposition and alignment are satisfactory, where alignment can be improved at operation without resection of the fibrous union, and where resection of the non-union is required to obtain adequate reduction. The prime indication for its use is the delayed or non-union site where increased internal fixation is needed in conjunction with the bone graft.
