Abstract:
ObjectiveTo explore the clinical outcome of one stage posteroanterior decompression and bone implant in the treatment of severe lower cervical spinal bony canal stenosis. Methods The study involved 29 patients with severe lower cervical spinal bony canal stenosis treated with one stage posteroanterior decompression and bone implant from April 2006 to March 2009. There were 11 patients with old fractures, seven with posterior longitudinal ligament ossification and 11 with cervical disc calcification. The course of disease ranged from 2 months to 3.2 years, average 1.4 years. The nerve function was rated as grade B in two patients, grade C in 19 and grade D in eight according to Frankel scale. The average Japanese Orthopaedic Association (JOA) score was 9.8. ResultsAll patients were followed up for 7-28 months (average 15.2 months), which showed bony fusion five months after operation, with fusion rate of 100％. The Frankel grade was increased for average 1.2 grades and the nervous symptoms alleviated remarkably. Mean postoperative JOA score was 13.8 and increased for mean 4.0, with mean amehoration rate of 55.6％. ConclusionsOne stage posteroanterior decompression and bone implant is a safe and effective method for treatment of lower cervical spinal bony canal stenosis, when the intraoperative electrophysiological monitoring can assure the operative safety.
