Extensive cervical laminoplasty for patients with long segment OPLL in the cervical spine: an alternative to the anterior approach.
We investigated treatment of long segment cervical OPLL by posterior decompression using a laminoplasty technique. Our aim was to both decompress the spinal cord and also to preserve neck motion. There were 38 patients treated by this posterior approach. Twenty-eight patients underwent C1-C7 expanding laminoplasty, 4 patients underwent C1-T1 expanding laminoplasty, and 6 patients C2-C7 expanding laminoplasty. The transverse width of the open-door laminoplasty was sufficient to achieve decompression of not only the spinal cord but also the nerve root outlets at each laminoplasty level. There were no complications related to this surgical technique, nor late deterioration in the mean follow up period of 4. 5 years. We propose expanding laminoplasty as an important option for the treatment of long segment cervical OPLL.
