Spinal cord morphology and dynamics during cervical laminoplasty: evaluation with intraoperative sonography.

Study Design: An intraoperative sonographic study for evaluating spinal cord decompression status was conducted.

Objectives: To analyze the spinal cord decompression status using intraoperative sonography and to evaluate the relation to postoperative neurologic recovery following cervical laminoplasty.

Summary Of Background Data: Since the 1980s, several papers have introduced that the intraoperative ultrasound allowed assessment of the adequacy of decompression and configuration of the spinal cord in compressive myelopathy.
