title: Comparison of donor-site engraftment after harvesting vascularized and nonvascularized iliac bone grafts.
abstract: OBJECTIVE
  The objective of this study is to characterize the donor-site morbidity after harvesting of nonvascularized and vascularized iliac bone grafts.
  
  
  METHODS
  Clinical data of 353 patients were collected for analysis. In addition, a questionnaire was sent to all patients asking about their perceptions of different parameters. In an individual age-matched layout, we compared 34 patients with nonvascularized iliac bone grafts with 34 patients with vascularized iliac bone grafts.
  
  
  RESULTS
  Transplantation of vascularized bone grafts has been increasingly performed at our institution. The mean age was 41.5 years in the nonvascularized group and 48.6 years in the vascularized group. The main reason for the bony defect in the vascularized group was malignancy. The majority of postoperative functional problems were observed in obese patients. No patient had serious or long-term complications at the donor site. The amount of bone graft taken affected postoperative sensitivity disturbance and caused postoperative functional problems and pain.
  
  
  CONCLUSIONS
  We conclude that the iliac crest is a suitable site for harvesting both vascularized and nonvascularized bone grafts measuring up to 10 x 3 cm. For larger defects that require a larger bone graft, a vascularized bone graft is more suitable with a better predictable healing capability. No significant differences in donor-site morbidity were found between the vascularized and nonvascularized bone grafts if a similar amount of bone was taken for transplant.
