What is cervical flexion?
What is neck flexion? Neck flexion is the movement of lowering your chin down to your chest. This occurs at the joint just below the skull and uses deep neck flexor muscles as well as the sternocleidomastoid (SCM) muscle. Other neck movements include: rotating the neck from side to side.
What is normal cervical flexion?
The cervical spine’s range of motion is approximately 80 to 90 of flexion, 70 of extension, 20 to 45 of lateral flexion, and up to 90 of rotation to both sides.

What is considered normal mobility in the cervical side bending test?
In this test procedure, the cervical spine is fully flexed, in an attempt to isolate movement to C1-C2, which has an unique ability to rotate in flexion. Normal range of rotation motion in end range flexion has been shown to be 44 to each side.

What causes cervical instability?
Some of the most common scenarios leading to cervical instability include: Trauma: Whether it is one major event, such a car crash, or microinjuries and repetitive trauma over time, trauma to the cervical spine can cause cervical instability.
How do you test cervical instability?
The following tests can be used to measure cervical instability but little is known about the diagnostic accuracy of upper cervical spine instability tests:Sharp-Purser test.Transverse Ligament Stress Test.Cervical flexion-rotation test.Neck Flexor Muscle Endurance Test and Craniocervical flexion test.
How is cervical instability diagnosed?
Cervical instability is a diagnosis based primarily on a patient’s history (ie, symptoms) and physical examination because there is yet to be standardized functional X-rays or imaging able to diagnose cervical instability or detect ruptured ligamentous tissue without the presence of bony lesions .
How do you test for atlantoaxial instability?
The patient is asked to slowly flex the head performing a slight cervical nod, at the same time the examiner presses posteriorly on the patient’s forehead. A sliding motion of the head in relation to the axis indicates atlantoaxial instability.
What does atlantoaxial instability look like?
Neurologic manifestations include clumsiness, lack of coordination, abnormal gait, difficulty walking, easy fatigability, neck pain, limited next mobility, torticollis, sensory deficits, neurogenic bladder, upper motor neuron signs (spasticity, hyperreflexia, clonus, Babinski sign), paraplegia, hemiplegia, and …
Which brace is used in atlantoaxial instability?
Initially, these patients are treated with a halo brace; however, if this treatment is unsuccessful because of a fixed deformity or recurrent deformity, posterior fusion of C1-2 is required. Posterior cervical spinal fusion can successfully treat symptomatic AAI in many cases.
What causes atlantoaxial instability?
Trauma as the sole cause of atlantoaxial instability is a unique entity and usually the result of a disruption of the transverse, alar, or apical ligaments. This type of injury is commonly associated with head trauma. Fractures of C1 or C2 also are traumatic causes of atlantoaxial instability.
What is subluxation mean?
Subluxation is a term that is used when a joint doesn’t work the way it’s supposed to, whether it’s simply not moving how it should or it’s misaligned. Subluxation leads to numbness, tingling, pain, and burning in that area of the body.
What is atlantoaxial instability Down syndrome?
Children with Down syndrome are at increased risk of developing compression of the spinal cord called atlantoaxial instability. This problem is caused by a combination of low tone, loose ligaments and bony changes. The spinal cord can be pressed by the bones and cause nerve damage.
What movement occurs at the atlantoaxial joint?
What movement decreases the angle between articulating bones?
Where is the Odontoid process?
Description. The odontoid process (also dens or odontoid peg) is a protuberance (process or projection) of the Axis (second cervical vertebra). It exhibits a slight constriction or neck, where it joins the main body of the vertebra.
Which joint is present between Atlas and Axis?
What is Atlas and Axis?
The atlas is the topmost vertebra and, with the axis (the vertebra below it), forms the joint connecting the skull and spine. The atlas and axis are specialized to allow a greater range of motion than normal vertebrae. They are responsible for the nodding and rotation movements of the head.
What is pivot joint?
Pivot joints, also known as rotary joints, are a type of synovial joint that permit axial rotation. The moving bone rotates within a ring formed by the concave surface of a second bone and an adjoining ligament.
