Abstract
Thirteen patients with cervical degenerative disorders were treated by laminoplasty combined with pedicle screw fixation. The mean improvement rate was 43.1%. Five screws out of 59 were dislocated from the pedicles, two in the transverse foramen and three in the spinal canal. However, neither neurological deterioration nor vertebral artery injury occurred. Loss of correction of cervical lordosis occurred in only one case. Although rigid internal fixation and decompression were obtained by this procedure, the surgical techniques for insertion of screws correctly into the pedicles were too difficult because the pedicles were excessively sclerotic and hypertrophic.
