2024年10月14日 · The cervical spine flexion and extension views demonstrate the seven vertebrae of the cervical spine when the patient is in a lateral position. These views are specialized projections often requested to assess for spinal stability.

Active cervical rotation usually results in a small amount of coupled lateral flexion and flexion/extension. The coupled movements of lateral flexion are usually greater than those in flexion/extension. Different studies have found that the average lateral flexion is either ipsilateral [2] or contralateral [1] to the direction of rotation.

2023年7月22日 · Cervical flexion and extension refer to the movements of the neck, specifically the forward and backward bending of the cervical spine (cervical vertebrae). Here’s a breakdown of each move: Cervical flexion: This movement involves bending the neck forward and bringing the chin to the chest.

The cervical spine is made up of two anatomically and functionally different segments. These two segments work together to produce rotation, lateral flexion, flexion and extension of the head and neck. It is made up of 7 vertebrae. The first 2, C1 and C2, are highly specialized and are given unique names: atlas and axis, respectively.

2023年8月28日 · Seven cervical vertebrae, combined with cartilages, various ligaments, and muscles, make a sophisticated and flexible structure that allows a variety of head/neck movements. Similar to other areas of the spine, cervical vertebrae also have intervening intervertebral disks for shock absorption and flexibility.

2023年11月9日 · While the cervical spine can undergo flexion, extension, rotation, and side-bending, each individual cervical joint has a primary motion. C1, the atlas, has no spinous process and articulates with the occipital condyles of the occiput bone of the skull, forming the occipital-atlanto (OA) joint.

2017年8月3日 · Motion of the Cervical Spine: The cervical spine can move axially and nonaxially in all three cardinal planes (sagittal, frontal, and transverse). The axial motions, shown in Figure 8, are as follows: Extension and flexion in the sagittal plane; Left lateral flexion and right lateral flexion in the frontal plane

Flexion and Extension of the Cervical Spine. These views are obtained with the patient performing maximal flexion and extension of their neck. They are used to assess alignment of the spine, and to look for ligamentous instability (ligament tears or laxity may result in vertebral bodies slipping forward or backward on each other).

2012年6月29日 · This exam is performed by removing the collar while the patient is sitting, so the thoracic and lumbar spines must be clear before ordering this. The patient then gently flexes and extends the neck to their limits of comfort. Images are …

Cervical spine radiographs are indicated for a variety of settings including 1-3: trauma. infection. atypical pain. limb pain. osteoporosis. degenerative changes. A decision to pursue C-spine imaging of any kind should be cross-referenced with the 'Canadian C-Spine Rule' for C-spine imaging due to its high sensitivity and specificity 4. Projections
