CERVICAL SPINE MOVEMENT INTER-VERTEBRAL DEGENERATIVE DISC DISEASE chiropractry graphics

Shows degenerative disc disease at C5-6 in the lateral view and the limitations in flexion-extension, lateral flexion and rotation due to the disease.

INTERVERTEBRAL DISC HEALTH

When you sit, stand up, bend or twist, large compressive forces are applied to your spine. There are several factors that determine the ability of your inter-vertebral discs to handle these forces:

your inherited make-up

disc health – worsened by smoking, poor nutrition, sedentary lifestyle, weak muscles, and obesity

ageing

poor posture – while sitting, standing and lifting

heavy loads during home, work or sporting activities.

DISC INJURY

Cervical Spine Movement Intervertebral Degenerative Disc Disease chiropractry graphics

When the forces applied to your neck exceed the strength of your discs, minor injuries to the disc can occur. It is important to note these injuries may or may not hurt at the time they occur.

DISC DEGENERATION

Cervical Spine Movement Intervertebral Degenerative Disc Disease chiropractry graphics

As the continuous stresses and repeated injuries accumulate, they cause wear and tear on the spine’s discs and joints. Some people are more susceptible to this degeneration, for reasons that are unclear. this disease process is called osteo-arthritis or spondylosis.

Often the annulus of the inter-vertebral disc is the first area injured. Small tears occur that heal with weaker scar tissue. As more scar tissue accumulates, the annulus becomes weaker overall.

This damages the inner nucleus, which loses it cushioning water content, and begins to dry up and stiffen. It changes from a jelly-like consistency, to more like crab meat. As it dries up, the height of the disc collapses. The decreased cushioning ability of the drier, weaker nucleus leads to even more stress on the annulus, and further annulus damage and nucleus collapse.

The attachment of the disc to the vertebra is placed under a lot of stress by this disc collapse, and the vertebra reacts by growing more bone in an attempt to get stronger. This can be seen as vertebral lipping (osteophytes, spurs) at the edges of the vertebral body and the unco-vertebral joints. This lipping can encroach on the spinal canal and adjacent nerves.

The alignment of the facet joints at the back of the spine alters to accommodate the disc collapse. This changes the way in which the facets slide over each other, causing increased wear of the cartilage on the joint surface. The cartilage frays, and is ground down to the underlying bone. When this facet joint osteo-arthritis or spondylosis occurs, the bone around the facet joint is irritated, and grows in an attempt to stop the excess motion.

These facet joint bone spurs, or osteophytes enlarge, and can grow into the intervertebral foramen or spinal canal, where they can compress the spinal nerve and the adjacent spinal cord.

The ligamentum flavum runs along the back of the spinal canal from one vertebra to the next. As the disc height collapses, and the adjacent vertebra move closer together, the ligamentum flavum thickens and buckles into the spinal canal, placing additional pressure on the spinal cord.

SUMMARY

So osteo-arthritis or spondylosis is a degenerative process that involves disc collapse and bulging, vertebral body and unco-vertebral joint lipping, facet joint osteophytes, thickening of the ligamentum flavum, and the slipping of the adjacent vertebra. This disease can put pressure on the spinal cord and adjacent nerves, and can cause pain.

TREATMENT

Cervical Spine Movement Intervertebral Degenerative Disc Disease chiropractry graphics
Although osteo-arthritis or spondylosis can not be reversed, there are things that you can do to slow it down and control any pain.

The safest and most effective treatments for osteo-arthritis or spondylosis include :

Stop smoking

Physical therapies - correct posture, activity modification (avoiding excess neck movements, physical activities above shoulder level), low impact and flexibility, strength and endurance exercises, hydrotherapy, physical therapy modalities such as heat, ice, massage, and manipulation or mobilization

Medications - early aggressive use of medication to reduce pain, inflammation, muscle spasm and sleep disturbance

Other treatments – ie acupuncture, ultrasound, laser, short-wave diathermy.

The use of neck bracing and acupuncture is controversial.

The amount of pain experienced from degenerative disc disease (osteo-arthritis, spondylosis) varies widely. This may be due to differing degrees of instability, scarring of the disc and facet joint osteo-arthritis. Once the degeneration is advanced, and the instability produces uncontrollable pain, or the pressure on the nerves affects their functioning, then your clinician will consider fusin

CERVICAL MUSCLES - SCALENES

1. SCALENUS ANTERIOR, ANTERIOR SCALENE, SCALENUS ANTICUS
DESCRIPTION
Scalenus anterior is one three deep muscles in the scalene group.

ORIGIN
Scalenus anterior originates from the anterior tubercles of the transverse processes of the third, fourth, fifth and sixth cervical vertebrae.

INSERTION
Scalenus anterior inserts onto the scalene tubercle on the inner border of the first rib, and to a ridge on the upper surface of the rib, anterior to the groove for the subclavian artery. medicolegal graphics.

INNERVATION
Scalenus anterior is innervated by branches from the ventral rami of C4, C5 and C6 spinal nerves.

BLOOD SUPPLY
Scalenus anterior is supplied by the inferior thyroid artery, a branch of the thyrocervical trunk.

ACTION
Scalenus anterior flexes and laterally flexes the neck.
Scalenus anterior assists in rotation of the head to the contralateral side.
Scalenus anterior elevates the first rib when the neck is fixed.

FUNCTION
Scalenus anterior assists with inspiration.

2. SCALENUS MEDIUS, MIDDLE SCALENE
DESCRIPTION
Scalenus medius is one three deep muscles in the scalene group.

ORIGIN
Scalenus medius originates from the transverse process of the axis and the front of the posterior tubercles of the transverse processes of the lower five cervical vertebrae.

INSERTION
Scalenus medius inserts onto the upper surface of the first rib, between the tubercle and the groove for the subclavian artery.

VARIATIONS
Scalenus medius often extends up to the transverse process of the atlas. medicolegal graphics.

INNERVATION
Scalenus medius is innervated by branches from the ventral rami of C3 to C8 spinal nerves.

BLOOD SUPPLY
Scalenus medius is supplied by the ascending cervical artery.

ACTION
Scalenus medius laterally flexes the neck to the ipsilateral side when the first rib is fixed.
Scalenus medius assists in rotation of the head to the contralateral side.
Scalenus medius elevates the first rib when the neck is fixed.

FUNCTION
Scalenus medius assists with inspiration.

3. SCALENUS POSTERIOR, POSTERIOR SCALENE
DESCRIPTION
Scalenus posterior is one three deep muscles in the scalene group.

ORIGIN
Scalenus posterior originates from the posterior tubercules of the transverse processes of the fourth, fifth and sixth cervical vertebrae.

INSERTION
Scalenus posterior inserts onto the outer surface of the second rib, behind the tubercle for serratus anterior.

VARIATIONS
Scalenus posterior is occasionally blended with scalenus medius. medicolegal graphics.

INNERVATION
Scalenus posterior is innervated by branches from the ventral rami of C6, C7 and C8 spinal nerves.
