- segmental defects:
- segmental defects are repaired w/ structural grafts;
- if sufficient bone is available from iliac crest & shaped to replace absent bone;
- central (medial wall absent)
- cavitary deficiencies
- the anterior and posterior columns and peripheral bone is intact;
- skeleton is intact and therefore these defects are easier to deal with than segmental defect;
- defects should be filled with graft;
- particulate graft is reversed reamed to pack evenly into defects
