PIVD ( prolapsed intervertebral disc ) in neck..
DEFINATION:The term PIVD /prolapsed intervertebral disc means the protrusion or extrusion of the nucleus pulposus through a rent in the
“Cervical radiculopathy is a disease process marked by nerve compression from herniated disk material or arthritic bone spurs. This impingement typically produces neck and radiating arm pain or numbness, sensory deficits, or motor dysfunction in the neck and upper extremities.”
About Herniated Disc :
Herniation of the nucleus pulposus (HNP) occurs when the nucleus pulposus (gel-like substance) breaks through the anulus fibrosus (tire-
like structure) of an intervertebral disc (spinal shock absorber).
A herniated disc occurs most often in the lumbar region of the spine especially at the L4-L5 and L5-S1 levels (L = Lumbar, S = Sacral). This
is because the lumbar spine carries most of the body’s weight. People between the ages of 30 and 50 appear to be vulnerable because the
elasticity and water content of the nucleus decreases with age.
stages of herniated disc
It has a four stages-
Bulging– At this early stage, the disc is stretched and doesn’t completely return to its normal shape when pressure is relieved. It retains a slight bulge at one side of the disc. Some of the inner disc fibres could be torn and the soft jelly ( nucleus pulposus ) is spiling outwards into the disc fibres but not out of the disc.
Protrusion- At this stage, the bulge is very prominent and the soft jelly centre has spilled out to the inner edge of the outer fibres, barely held
in by the remaining disc fibres.
Extrusion- In the case of a herniated spinal disc, the soft jelly has completely spilled out of the disc and now protruding out of the disc fibres.
Sequestration- Here some of the jelly material is breaking off away from the disc into the surrounding area.
Cervical radiculopathy is a dysfunction of a nerve root in the cervical spine, is a broad disorder with several mechanisms of pathology and it
can affect people of any age, with peak prominence between the ages of 40-50. Reported prevalence is of 83 people per 100,000 people .
Annual incidence has been reported to be 107,3 per 100.000 for men and 63,5 per 100.000 for women.
The two main mechanisms of the nerve root irritation or impingement are:
1.Spondylosis: leading to stenosis or bony spurs – more common in older patients
2.Disc herniation – more common in younger patients.
You may have first noticed pain when you woke up, without any traumatic event that might have caused injury. Some patients find relief by holding their arm in an elevated position behind their head because this position relieves pressure on the nerve.
1.An MRI : It can detect which disc is damaged and if there is any nerve compression. It can also detect bony overgrowth, spinal cord tumors, or abscesses.
2.CT scan :This test is especially useful for confirming which disc is damaged.
3.electromyography(EMG) & Nerve Conduction Studies (NCS): EMG and NCS tests measure the electrical activity of your nerves and muscles.
4.Myelograms: It can show a nerve being pinched by a herniated disc, bony overgrowth, spinal cord tumors, and spinal abscesses. A CT scan may follow this test.
5.X ray :It’s not possible to diagnose a herniated disc with this test alone.
Provocative tests are performed to provoke or worsen the symptoms in the affected arm and are indicative of cervical radiculopathy.
– The examiner turns the patient’s head to the affected side while extending and applying downward pressure to the top of the patient’s head. A positive Spurling’s sign is when the pain arising in the neck radiates in the direction of the corresponding dermatome ipsilaterally.
2.Upper limb tension-1
The patient is supine. The examiner performs the following movement sequence:
-Forearm supination, wrist and finger extension
-Shoulder lateral elevation
-Contralateral/ipsilateral cervical side bending
Patient lies supine and the neck is comfortably positioned. Examiner securely grasps the patient’s either by placing each hand around the patient’s mastoid processes, while standing at their head, or place one hand on their forehead and the other on the occiput. Slightly flex the patient’s neck and pull the head towards your torso, applying a distraction force.
4.Involved side cervical rotation range of motion less than 60 degrees.
1.Anterior Cervical Dissectomy (decompression) (ACD),
2.Anterior Cervical Dissectomy and Fusion (ACDF),
3.Total Disc Arthroplasty (TDA),
Epidural steroid injections can also be used as treatment for cervical radiculopathy. The injections are given under the guidance of fluoroscopy or CT.
1.Education and advice
2.Manual Therapy .
3.Exercise Therapy – AROM, stretching and strengthening
1.EDUCATION AND ADVISE
Education is key to getting the patient on side and to work co-operatively with physiotherapy. If a patient understands the condition and the reason for the neck and arm pain then they are more likely to be compliant with any rehabilitation plan.
Cervical glides and cervical spine manipulations are beneficial to relieve pain.
Cervical traction given to reduce compression of nerve.
ROM increases strengthening exercises can be performed to develop stability and reduce the risk of developing nerve root irritation. Exercises such as contralateral rotation and sideflexion are amongst the simplest forms of exercises which are effective against signs and symptons, given in the form of active ROM. Patient should be instructed to remain as active as possible and perform exercises daily on the days between therapy sessions.
Understand the patient about postural re-education.ask the patient to hold the head in neutral position.
