Anterior cervical fusion with the Caspar instrumentation system.
We reviewed 106 consecutive patients who had undergone anterior cervical fusion with the Caspar instrumentation system between 1984 and 1989. Preoperative diagnoses were cervical spondylosis in 73 patients, a traumatic lesion in 12, ossification of the posterior longitudinal ligament in 9, cervical disc herniation in 6, and tumour or miscellaneous lesions in 6. In the 106 patients, 56 had two levels fused and 27 had three levels fused. At an average duration of follow-up of 4 years and 7 months, nonunion occurred in 3 of the 83 patients with multiple level fusions. Screw loosening occurred in 8 of the 106 patients, but there was no oesophageal perforation.
