Titanium cage reconstruction after cervical corpectomy.

Abstract

The authors evaluated the efficacy of titanium cage- and anterior cervical plate (ACP)-augmented fusion for reconstruction following decompressive cervical corpectomy in nontraumatic disease. Forty-five patients ranging from 37 to 77 years of age underwent anterior cervical corpectomy followed by titanium cage-assisted reconstruction in which the cages were filled with autologous bone obtained from the resected vertebral bodies (VBs). Plates were placed in all patients. Follow-up radiographic evaluation included computerized tomography scanning and plain flexion-extension radiography. Fusion was demonstrated in all but one patient without reconstruction-related complications. The single complication involved an endplate VB fracture with pistoning of the cage into the VB. The mean follow-up period was 12.9 months. Autologous corpectomy bone-filled titanium cages supplemented with ACPs are an effective means of reconstruction after compressive cervical corpectomy. This technique provides a reasonable alternative to procedures involving long solid strut grafts obtained from the bone bank or from the patient.
