CERVICAL DISK SYNDROMES
Cervical Disk Syndromes
The cervical region has seven cervical vertebrae separated by intervertebral disks.
Each disk comprises a central nucleus pulposus and a surrounding annulus fibrosus.
Functions of the disk:
Acts as a shock absorber.
Enhances mobility of the cervical spine.
Cervical Disk Syndrome occurs when disk material herniates due to:
Trauma
Old age
Over 90% of cervical disk lesions occur at C5 and C6 due to their mobility.
Types of Disk Lesions
Soft Disk Lesions
Common in young adults following trauma.
Characterized by nuclear herniation through the wide annulus fibrosus.
Hard Disk Lesions
More frequent in older adults.
Gradual onset, often due to cervical spondylosis.
Rarely, large posterior osteophytes cause pressure on the anterior spinal cord.
Clinical Features
Patients often report:
Gradual or acute neck pain.
Morning stiffness.
Pain worsens upon neck extension.
Tingling and numbness from nerve root compression.
Radiating pain extending to the neck, shoulder, upper arm, forearm, and hand.
Decreased neck movement due to pain.
Localized tenderness over the spinous process and trigger point tenderness at the scapular region.
Increased pain from head pressure.
Sensory, motor, and reflex changes may follow a dermatomal pattern if nerve root is compressed.
Rarely, symptoms may develop in lower limbs due to posterior osteophytes affecting the cervical cord.
Investigations
X-ray - Normal in soft lesions; hard lesions show:
Disk space narrowing
Anterior and posterior osteophytes
Narrowing of intervertebral foramina
MRI - Non-invasive, useful for localizing lesions but costly.
CT Scan - More effective for traumatic neck conditions than degenerative ones.
EMG - Evaluates muscular and nerve function.
Rehabilitation / Treatment
Conservative Treatment:
Rest is crucial to allow healing by reducing inflammation.
NSAIDs are typically used.
After pain reduction, isometric neck exercises are introduced.
Measures to Reduce Cervical Pain and Spasm
Thermotherapy:
Superficial: IFT, TENS, infrared rays, hydrocollator packs.
Deep: Ultrasound, SWD, microwave.
Cryotherapy: Ice packs, ice massage.
Massage: Techniques like friction and circular kneading for pain relief and muscle relaxation.
Measures to Strengthen and Mobilize the Neck
Importance of exercises in muscle strengthening and mobilizing the neck:
Strengthening Exercises: Strong isometrics when movement is restricted.
Weaker Muscle Rehabilitation: Active assisted exercises.
Mobilization Exercises: Active and passive movements.
Combined Exercises: PNF techniques.
Cervical Traction and Collars: To aid treatment.
Additional Measures
Maintain an appropriate neck posture (straight neck with chin tucked) during all activities.
Use properly sized pillows to maintain neutral neck position relative to shoulders during sleep.
