Fractures of the iliac crest following anterior and posterior bone graft harvesting. Review of the literature and case presentation.
Iliac crest is the most commonly used extra-oral donor site of autologous non-vascularized bone, because of the great amount of bone available and easy access. Bone grafting from the ileum, however, is not without complications. An extensive review of the literature focusing on fractures of the iliac crest and pelvic ring instability due to anterior and posterior bone graft harvesting is reported, and 1 case of anterior stress fracture of the iliac crest is described. Thirty-five of the 37 fractures described up to date in literature were divided in 2 groups depending on the region of bone graft harvesting. Twenty-four fractures - including our case - were related to bone graft harvesting from the anterior region, 12 were due to harvesting from the posterior region. Four out of 24 anterior fractures required further surgical treatment (16.6%). In 8 of the 12 fractures with pelvic ring instability due to posterior bone harvesting, 1 or more additional surgical procedures were performed in order to stabilize multiple fracture sites (66.6%). Anterior iliac crest fractures, even though painful, remain stable and heal spontaneously in most cases without further complications. On the contrary, fractures due to posterior iliac crest harvestings very often require complex surgical treatments and lead to significant disability, which can be permanent.
