The purpose of this study was to compare modified plate-only laminoplasty and laminectomy and fusion to confirm which of the 2 surgical modalities could achieve a better decompression outcome and whether a significant difference was found in postoperative complications. Clinical data were retrospectively reviewed for 141 patients with cervical stenotic myelopathy who underwent plate-only laminoplasty and laminectomy and fusion between November 2007 and June 2010. The extent of decompression was assessed by measuring the cross-sectional area of the dural sac and the distance of spinal cord drift at the 3 most narrowed levels on T2-weighted magnetic resonance imaging. Clinical outcomes and complications were also recorded and compared. Significant enlargement of the dural sac area and spinal cord drift was achieved and well maintained in both groups, but the extent of decompression was greater in patients who underwent laminectomy and fusion; however, a greater decompression did not seem to produce a better clinical outcome. No significant difference was observed in Japanese Orthopaedic Association and Nurick scores between the 2 groups. Patients who underwent plate-only laminoplasty showed a better improvement in Neck Dysfunction Index and visual analog scale scores. In addition, limited decompression, rigid reconstruction of the spinal canal, and preservation of cervical mobility combined with preservation of the posterior structure resulted in a lower rate of postoperative C5 palsy and axial pain in the modified laminoplasty group. For this reason, modified laminoplasty may be a more viable option for patients with cervical stenotic myelopathy.
