Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary objective of this study is to investigate whether the sequence of segmental contributions in the cervical spine in the long-term follow-up of ACD and ACDF had changed compared to the short-term follow-up and if this correlates to clinical symptoms. At the start of the cinematographic recording, one image will be saved as a lateral X-ray of the cervical spine to determine Kellgrens* Score (KS). The KS will be determined by two neurosurgeons and is a scoring method to determine severity of degenerative disc disease, using five gradations: * Grade 0: absence of degeneration in the disc. * Grade 1: minimal anterior osteophytosis. * Grade 2: definite anterior osteophytosis, possible narrowing of the disc space, some sclerosis of the vertebral plates. * Grade 3: moderate narrowing of the disc space, sclerosis of the vertebral plates, osteophytosis. * Grade 4: severe narrowing of the disc space, severe sclerosis of the vertebral plates, multiple large osteophytes. Cinematographic recordings: participants are seated on a crutch, adjustable in height, with their neck, shoulders and head free. Before recordings are made, participants will be instructed to perform the prescribed flexion and extension movement in about 10 seconds with 7 frames per second. . Participants are placed on the crutch with their shoulder*s perpendicular to the image intensifier to obtain sagittal images from the occiput till C7. As soon as the recording is started, the participant is instructed to move his head in the sagittal plane from maximal extension to maximal flexion, without moving the upper part of the body. It is important that the participants shoulders are kept as low as possible while making the recordings to ensure that all the cervical vertebrae are visible. The movement of the cervical spine should be as fluent as possible to prevent for sudden large rotations and translations between consecutive frames. The cinematographic recordings will be mad | — |
Secondary
| Measure | Time frame |
|---|---|
| The secondary outcome will be to determine the radiological sROM on the cinematographic recordings. The amount of degeneration will be assessed on the lateral X-ray according to the Kellgren's Score (KS). Clinical outcomes will be assessed according to the visual analogue score (VAS) score for neck and arm pain, the neck disability index (NDI), SF-36 and Odom Outcome Score. Patients will be asked to indicate whether they have been diagnosed with new episodes of CDDD and how these were treated. All patients will receive a clinical neurological exam to objectify clinical outcomes. | — |
