A Novel Local Cancellous Autograft Source for Anterior Cervical Discectomy With Fusion

STUDY DESIGN: Case series. OBJECTIVES: Successful clinical outcome scores following anterior cervical discectomy and fusion (ACDF) have been correlated with high fusion rate. Published fusion rates using iliac crest bone graft (ICBG) have been shown to be as high as 100% for single-level fusions in some studies; however, there is potential associated morbidity with ICBG harvest. This technical description and preliminary case series assessed the clinical efficacy and results of a novel grafting technique for ACDF. METHODS: Twelve patients underwent novel grafting technique for ACDF in which autograft was procured from the cervical vertebra adjacent to the operative disk. Patients were followed for 2 years using visual analogue pain scale (VAS) and radiological assessment of fusion. RESULTS: Patients experienced clinically meaningful reduction of radicular symptoms in the affected arm(s) with an average preoperative VAS score of 5.0 ± 0.8 and an average 2-year postoperative score of 1.108 ± 0.475 (P = .0013). Patients also experienced significant resolution of neck pain with an average preoperative VAS score of 7.1 ± 0.5 and average 2-year postoperative score of 2.708 ± 0.861 (P = .0018). All patients achieved solid fusion by 1 year. There were no major or minor complications noted during follow-up. CONCLUSIONS: This procedure allows for both autograft harvest and cervical decompression to be performed through a single incision. In this series, this technique eliminated the morbidity associated with autograft harvest from the iliac crest while achieving high fusion rates and without additional technique-related complications.
