The aim of this study was to evaluate the postoperative morbidity at the donor site and the long-term outcome after the harvest of bicortical iliac bone grafts, including the iliac crest and the anterior superior iliac spine (ASIS), by using a confirmed score. We retrospectively examined 54 consecutive patients who had had vascularised iliac bone grafts harvested to reconstruct different parts of the mandible. We used the Harris Hip Score to evaluate objectively the long-term postoperative morbidity at the donor site. Of 54 patients, 20 were female (37%) and 34 male (63%), with a mean age of 49 years (range 12-81). The causes of the bony defects were malignancy (n=37, 69%), benign tumours (n=7, 13%), osteomyelitis (n=9, 17%), and atrophy of the alveolar ridge (n=1, 2%). All transplants healed adequately. A total of 38/52 patients (73%) had a score of more than 80 points, which defines clinical success. Vascularised iliac bone grafts offer excellent bony dimensions with optimal shape to be used for reconstruction of different parts of the mandible. They can be harvested bicortically, including the iliac crest and the ASIS, with acceptable morbidity at the donor site. The Harris Hip Score is an appropriate tool for the evaluation of long-term impairment at the donor site after the harvest of vascularised iliac bone grafts, and it could be used to compare the results of different studies.
