Objective     To evaluate the replantation of lamina and spinous process during laminoplasty in posterior thoracolumbar surgery.      Methods     Forty-three cases including 8 cases of spinal canal tumors

35 cases of spastic cerebral palsy treated with selective partial anterior and posterior rhizotomy. After the spinous process was cut vertically

both sides of a lamina were separated horizontally and replanted.      Results     After 18 month follow-up

replanted lamina and spinous process of all cases got bony fusion and good stability

without spinal stenosis or compression owing to scar.      Conclusion     This method can provide good operative exposure

maintain the spinal integrity and avoid nerve root compression due to the spinal canal scar.
