Is “mini-invasive” technique for iliac crest harvesting an alternative to cervical cage implant? An overview of a large personal experience

Background: Autograft bone provides an excellent substrate for multilevel arthrodesis after anterior discectomy and is inexpensive. However, the use of tricortical bone could increase the discomfort for the patient. Methods: We reviewed cases of cervical disc diseases operated on by a single neurosurgeon (AS), within the period June 2000-December 2011. A total of 221 patients were considered for the present study; 109 female, 112 male, averaging 49 years of age. Only patients who could be followed up for at least one year were included in the present study. The grafts obtained with the technique described are bi- (and not tri-) cortical, and always of sufficient size in order to fit two spaces if necessary. Results: The technique is not associated with long-term significant donor site pain except for a striking minority of patients, it shortens the hospital stay, it offers comparable results to the published surgical series in which cage and/or modern implants are used. Conclusions: Autograft bone can be reasonably considered as one of the possible alternatives to be used in the surgical management of cervical disk disease.
