What is subluxation of the cervical spine?
Anterior subluxation (hyperflexion sprain) is localized, purely ligamentous disruption of the cervical spine caused by a limited flexion force. When associated with a simple wedge fraction, also a flexion injury, anterior subluxation may be the more significant lesion.
What is anterior subluxation C4 C5?
Anterior subluxation of C4 over C5 is associated with an increase in facet joint gap/distraction. This is likely due to a hyperflexion mechanism. Disruption of three columns and instability needs to be suspected in this case until proven otherwise.
Which of the positions illustrated in the figure below will best demonstrate the lumbar Zygapophyseal joints closest to the IR?
Which of the following positions will best demonstrate the right zygapophyseal articulations of the lumbar vertebrae? The correct answer is (C). The posterior oblique positions (LPO and RPO) of the lumbar vertebrae demonstrate the zygapophyseal joints closer to the IR.
Which of the following is located at the interspace between the fourth and fifth thoracic vertebrae?
Which of the following is located at the level of the interspace between the fourth and fifth thoracic vertebrae? in positioning various body structures. The jugular notch, located at the superior aspect of the manubrium, is approximately opposite the T2-3 interspace.
What causes subluxation of cervical spine?
Subluxations are caused by accidents, falls, sports injuries, birth stress and other trauma or by bad posture or even emotional stress. Infants and children need to have their spines checked by a doctor of chiropractic as neurological and other health problems have been traced to spinal damage at birth or infancy.
Is subluxation serious?
A subluxation is a condition that is typically only used by chiropractors and experts in the medical field. However, when a subluxation occurs, the entire nervous system can be disrupted, which makes the condition serious.
Can subluxation fix itself?
While complete dislocations often need to be guided back into place, subluxations (as long as the joint remains in alignment) can heal on their own with proper rest, ice, elevation, anti-inflammatory medication (RICE) and a splint or brace for added support and stability.
What causes anterior subluxation?
Anterior cervical subluxation is sustained as result of flexion-rotation injury in which the traumatic force is not sufficient to cause disruption of the apophyseal joints and interlocking of articular facets [1 ]. Anterior subluxation is considered to be due to injury of the posterior ligamentous complex.
Which projection of the lumbar spine best demonstrates the zygapophyseal joints?

|The lumbar zygapophyseal joints are best visualized in what radiographic position?||45° oblique|
|What is best demonstrated on a lateral projection of the L-spine?||lumbar intervertebral foramina|
Why should the hips and knees be flexed for an AP projection of the lumbar spine?
Why should knees and hips be flexed for an AP projection of the lumbar spine? Opens the intervertebral disk space by reducing the normal lumbar curvature of the spine.
