THE USE of cineradiography provides an additional radiographic evaluation of skeletal pathologic change. By continuous cineradiographic demonstrations of the cervical articulations during motion, abnormalities are visualized that may account for symptoms.
Observations have been reported previously relating to cervical traction and some pathologic processes affecting the cervical spine.1,2 In the present study, we reviewed cineradiographic recordings of the cervical spine in 33 patients who had been subjected to laminectomy. In seven patients, the spine had also been studied before laminectomy, and in nine patients, the spine had been fused surgically.
All the preoperative cineradiographs were made within the three-month period before surgical procedure. All postoperative recordings were done within a year after the operation, and in a few cases, including those which required spinal fusion, recordings were repeated within a five-year period.
The laminectomies varied in extent from one to five segments. During surgery, the type and extent of
