Fibular allograft after anterior cervical corpectomy: long term follow-up.

Abstract

The purpose of this study was to provide clinical and radiographic evaluation after a minimum of two years in patients who had an anterior cervical corpectomy and a fibular allograft strut. Nineteen patients returned for a follow-up visit which included independent radiographic evaluation as well as completing a Visual Analogue Scale and Oswestry and Short-Form 36 questionnaires. The categories of fusion were as follows: 1) definitely fused (84%) 2) questionably fused (11%) 3) definitely not fused (5%). The average VAS was 29 mm (range 0-85). The Oswestry Back Scores showed relatively low levels of significant pain with an average score of 29 (range 0-73). Anterior cervical corpectomy followed by an allograft fibular strut provides for relatively high rates of arthrodesis without severe loss of height or sagittal alignment at long term radiographic follow-up.
