Abstract
Eighty-eight consecutive patients underwent anterior cervical discectomy (ACD) with banked fibula fusion and internal fixation using the locking cervical plate. Pathology included cervical spondylotic radiculopathy in 48, cervical spondylotic radiculomyelopathy in 30, cervical facet dislocations with associated disc herniations in six, and autologous iliac crest graft collapse pseudoarthrosis with recurrent symptoms in four patients. Operations were single-level banked fibula fusion with plating in 37, multilevel banked fibula fusion with plating in 45, and combined single-level ACD banked fibula fusion with plating and posterior fusion in six patients. The only perioperative complication was transient hoarseness. There were no transfusions, infections, neurological injuries, or deaths. The mean time in the hospital for the nontraumatic cases was 1.8 days. The mean follow up was 22 months (range 12-30 months). There has been no motion at the fused level on flexion/extension films, no kyphosis, no screw plate backout, and no banked fibula has suffered graft collapse. Following a high-speed motor vehicle accident 6 months after a multilevel fusion, one alcoholic man suffered a fractured plate with transient worsening of neck pain, and the plate has remained in place for an additional 11 months of follow-up care. Compared to 100 consecutive autologous iliac crest fusions performed by the same surgeon, there were significantly fewer graft-related complications (p < 0.001). There was a significantly greater chance of autologous iliac crest collapsing with the passage of time as compared to banked fibula. Time until return to work was shorter by 5 weeks for the plate/banked fibula group (p < 0.05). When fusion is considered following ACD, the combination of banked fibula and locking cervical plates is significantly superior to autologous iliac crest grafts.
