EO 09.02 Flashcards
Neck pain is classified in 2 groups:
- Pain mainly from joint and associated ligaments or muscles
- Sign of radiculopathy (nerve root) (radicular pain) or, Sign of myelopathy (spinal cord lesion, stenose, compression)
Cervical soft tissue injuries MOI
MOI:
- Mechanical Neck Disorders (activity related)
- Neck strain, sprain, acceleration-deceleration injury, hyperextension/flexion, whiplash
- MVCs, falls, sports, work-related injuries precipitate most cases
Acute or chronic
Cervical soft tissue injuries Clinical Presentation
- Pain and stiffness
- Deep, dull aching, often episodic
- Hx excessive activity/sustaining awkward posture
- May be no hx specific injury
- Ligament/muscle pain localized & asymmetric
- Pain from upper segments referred twd head; lower segments twd upper limb girdle
- Symptoms aggravated by movement, relieved by rest
Cervical soft tissue injuries Common Management Strats
- Improvement with minimal intervention
*Act as usual, avoid activities that cause pain - NSAIDs, muscle relaxants
- Opiates (significant pain)
- F/U to determine need for physical/manual therapies
Cervical hyperextension flexion (Whiplash) MOI
- Sudden acceleration-deceleration that occurs when unaware victim in a stationary vehicle struck from behind
Cervical hyperextension flexion (Whiplash) Clinical Presentation
- Typically pain delayed following accident
- Pain, stiffness, tender paracervical muscles
- Uncommon/highly variable:
Headache, vertigo, dizziness, spatial instability, dysphagia, hoarseness
** Brain, spinal cord, or carotid or vertebral artery dissection should be considered whenever neurologic findings are seen after whiplash injury**
Cervical hyperextension flexion (Whiplash) Common Management Strategies
- Similar to cervical soft tissue inj
- Maintain motion as tolerated
- Analgesics
- Muscle relaxants
Pathophysiology – Cervical Hyperextension/Flexion
- Upward/backward injury to frontal head, jaw, face
May involve: - Soft tissue (whiplash, strain, sprain)
- Vertebral structures
Spinal cord*
Vascular
Central cord sydrome (CCS) most devastating complication
Clinical presentation - Cervical Hyperextension/Flexion (Whiplash)
- Neck pain, stiffness
- Headaches
- Paresthesia/numbness
- Shoulder pain, spasms, tenderness
- ↓ ROM
- Radicular signs
- Forehead/face/jaw abrasion, laceration, or contusion
Cervical hyperextension/flexion Common management strategies
- If soft-tissue same management as cervical soft-tissue inj – NSAIDS, muscle relaxants, possible referral to physical/manual therapies. Pt education
- CCS without instability:
Bed rest with soft collar 4-6 wks
IV steroid - Surgery considered with deterioration/ ↑
Stable fractures
Rigid collar 8-14 wks fol by mobilization - Unstable fractures
Surgery - Vascular dissection
Cerebral angiogram and anticoagulation (prevent ischemic embolic events)
Cervical Spondylosis Patho
- Progressive, degenerative condition
- Presents as loss of cervical flexibility, neck pain, occipital neuralgia (nerve damaged/inflamed), radicular pain (radiation pain from spine>back> legs), or progressive myelopathy (severe compression; occasional)
- Progressive degeneration of ligaments, disks, facet joints
- Osteoarthritis of the neck and Degenerative Disk Disease common terms used for this condition
Cervical Spondylosis Clinical Presentation
- Neck pain/soreness with radiation twds occiput/ shoulder and scapular region
- Loss of neck extension
- Lateral flexion limited
- Headache
- Cervical spondylotic radiculopathy (sharp, tingling, burning)
- Cervical spondylotic myelopathy, gait disturbance, loss of upper fine motor control, bowel/bladder dysfunction (late)
Cervical Spondylosis Common Management
- Pt education
- Activity restrictions
- Soft cervical collar
- Analgesics, muscle relaxants
- Physio – ultrasonic tmt with muscle stimulation
- Avoidance of activities that produce strain/pain
Spasmodic Torticollis Patho
Torticollis is involuntary contractions/spasms of the neck muscles causes the neck to turn from its usual position.
Spasmodic Torticollis is usually Idopathic
the head tilt and rotation are involuntary movement
Most common cervical dystonia
Some causes may be:
- Muscular damage from inflammatory disease
- Age (20-60)
- Cervical spine injuries
- Cervical spondylosis
- Ocular disorder
- Tumor
Spasmodic Torticollis Clinical Presentation
- Head tilt to affected side; chin rotates to opposite side
- Initial neck stiffness, progressing to pain & head jerking
- Painful spasms
- C-spine tenderness
- ROM restrictions with pain
Spasmodic Torticollis Common Management
- Physical measure – light touch (sensory biofeedback) on jaw on same side as head tilt / any light touch.
- Soft cervical collar
- Heat/ice
- Bed rest
- Analgesics/muscle relaxant
- Botulism Toxin type A & B
- Rarely, emotional problems contribute - psychiatric tmt indicated.
Mechanical Lower Back Pain Physiopathology
AKA Non-specific back pain
- Anatomic/functional abnormality in absence of neoplastic (benign or malignant mass (CA)), infectious, or inflammatory disease
- Usually acute (<3month), idiopathic, benign & self-limiting
- Represents 97% of symptomatic LBP
- Commonly work related
- Risk factors
- Heavy lifting / improper lifting
- Poor conditioning
- Obesity
- Often arises from muscle/ligament injury
Typical mechanism minor exertion/lifting
Mechanical Lower Back Pain Clinical Presentation
- Paraspinal muscle/facet tenderness
- Paraspinal muscle spasm may present with absent lumbar lordosis
- Mild-mod pain with movement ; relieved by rest
- No motor/sensory loss/reflex abnormalities
Mechanical Lower Back Pain Common Management
Continue daily activities (using pain as limiting factor)
- Ice/heat
- Analgesic, manipulation, physio
- Monitor 4-6 wks; 80-90% pt’s symptoms will resolve on own without requiring a diagnostic evaluation.
- Acetaminophen / NSAIDs
- Opioid (mod-severe pain)
- Pt Education** (red Flags)
Lumbar Disc Herniation Physiopathology
Disk herniations occurs as the nucleus pulposus protrudes through the posterior annulus fibrosis, producing either an acute radiculopathy or, occasionally, a myelopathy.
Lumbar Disc Herniation Clinical Presentation
- Dx suspected clinically and confirmed with non-urgent MRI
- Pts complain of radicular symptoms more than back pain
- > 95% occur at L4-L5/ L5-S1
- Localization of pain & neurological deficit in unilateral single nerve root (usually L5/S1)
- Straight leg raise
- ↑ pain with coughing, valsalva, sitting
- Pain relieved by lying supine
Lumbar Disc Herniation Common Management
- Pt education!
- Similar tmt as Mech LBP
- Routine activity as limited by pain
- Physio
- Oral Meds (acetaminophen, -NSAIDs, opiates, muscle relaxant)
- Ice/heat
Sciatica Pathophysiology
- “sciatica” is used for radicular back pain following the lumbar or sacral nerve root
- Often accompanied by sensory or motor deficits
- Only occurs in 1% of pts with back pain, however is present in 95% pts with symptomatic herniated disc
- Usually seen at L4-L5 or L5-S1 disk space
- Most common cause of sciatic pain – compresses or impinges on spinal nerve roots, cauda equine* or spinal cord
Sciatica Common Management
- If no risk factors for serious disease, treat conservatively similar to herniated disk
- If tmt ongoing with no improvement, surgery may be considered
- Steroids…widely used, however little measurable benefit
If the patient has a demonstrable neurologic deficit, consider obtaining plain radiographs to look for other possible causes for symptoms such as tumor, fracture, spondylolisthesis, and infection.
Lumbar Disc Disorders Pathophysiology
- Many pts with LBP have lumbar disc disease & involvement surrounding spinal ligaments, muscles, skeleton
- Over time may progress to disc degeneration, herniation, spinal narrowing, arthritic growth
- In younger pts
Source likely due to mech compression/ chemical irritation - In older pts (>55)
Spinal stenosis likely to be etiology
Lumbar Disc Disorder Clinical Presentation
- Variable pain
- Pain may radiate in nerve root dist
- Back pain ↓ at night
- Pain ↑ sitting/standing
- Sciatica can occur w/out back pain
- Paresthesias/numbness in extremities
- Occasional muscle group weakness
Lumbar Disc Disorder Clinical Common Management
- Conservative tmt 4-6 wks
- Minimize bed rest, activity as tolerated, heat, analgesic, NSAID, muscle relaxant, physio, (Symptomatic relief)
- Chronic nonradicular pain
Improve physical fitness, after pain controlled begin progressive walking prgm - Surgical consult
Persistent/severe pain & neuro deficits
Nerve Root Disorders Pathophysiology
- AKA radiculopathies
Precipiated by chronic pressure on a root in or adjacent to the spinal column - Most common: Herniated disc
- Bone changes (RA or OA) may compress/isolate nerve roots
- Infectious disorders sometimes affect nerve roots
Nerve Root Disorders Clinical Presentation
- Radicular pain & neurologic deficits
- Muscle weakness/atrophy
- Sensory impairment (dermatomal)
- DTRs may be diminshed/absent
- Electric shock-like pains
- Pain exacerbated by movement
- Lesions of cauda equine
- Radicular symptoms bilat, impaired sphincter and sexual function
Nerve Root Disorders Common Management
Depends on cause but includes symptomatic relief
- Analgesics
- NSAIDs
- MRI/CT
- Tricyclic antidepressants/anticonvulsant
- Physio/ Mental health consult
- Alternative medical tmts
