Spondylosis (OA) - Lumbar
Spondylosis (OA) Lumbar
Definition
 “Spondy” is Latin for spine
 “Losis” is the Latin term for problem.
 Not only osteoarthritis of the lumbar spine, but also
implies the degeneration of a intervertebral disc or
even of the vertebra itself.
 Degeneration of the spine caused by wear and tear on the
vertebral joints in the lumbar area.
Referred to by many names
 Lumbar arthritis
 Disc degeneration
 Degenerative disc disease
Pathophysiology
 Symptoms more common in persons over 60 years of age
(wear and tear)
 However degeneration can start at 30 years of age.
 Associated with several other phenomena:
•
•
•
Spinal stenosis
Osteoarthritis of spinal joints
Degenerative disc disease
 Not life threatening, but can cause nerve damage with
resultant devastating effects.
Phases of degeneration
 3 Phases
 Phase 1: Dysfunction phase
o Repetitive micro trauma
o Painful tears of outer, innervated annulus fibrosis and
associated end-plate separation
o This compromises disc s’ nutritional supply and waste
removal
o Result: dehydration and loss of disc height
 Phase 2: Instability phase
o Characterised by loss of mechanical stability
o Progressive disc changes of resorption
o Internal disruption
o Additional annular tears
o Further facet degeneration
o Result in sublaxation and instibility (ligament laxity due
to deformities)
 Phase 3: Stabilization phase
o Disc space narrowing
o Fibrosis along with the formation of osteophytes
o Transdiscal bridging
Causes
 Wear and tear is most NB cause!!!!!!!!
• Lumbar and cervical spine have to support the weight of the
head and upper body.
• Increases with age.
• Extreme athletics
 Injury to vertebra (specifically lumbar region)
• Less common
 Severe arthritis
 Degenerative disc disease
 Spinal stenosis
Risk factors
 Advancing age
 Past injury to spine
 Heredity factors
 Smoking
Most common signs and
symptoms
 Pain
 Tingling
 Numbness
 Weakness – start in lower back and then radiate through

buttocks, hips, legs, feet and toes.
Stiffness in back
Loss of sensation
Loss of balance
Loss of bladder and bowel control
Muscle spasms
Complications
 Chronic pain
 Faecal and urinary incontinence
 Permanent disability (rare)
Treatment
1. Pain management

discomfort.
Short course pain medication (NSAIDs)
• Voltaren
Muscle relaxants
Nerve pain medications
Antidepressants (low dosages)
Traction
2. Physiotherapy
 Ice or heat modalities
 Electrotherapy
 Strengthening exercises
 Acupuncture
 Massage therapy
 May also benefit for yoga
3. Surgery
 Only if conservative treatment fails
 Spinal fusion and spine decompression.

treatment approaches
Lower back pain (LBP) affects 60-85% of adults at
some point in life.
90%- symptoms disappear within 6 weeks.
15-45% develop chronic back pain.
Sometimes difficult to determine the exact cause of
LBP.
Comparisons between
different articles
 All articles identified that disc degeneration can be
established in most cases between the ages of 20-29.
 Most symptoms can appear at age 40, but normally appear at
>60 years of age.
Anatomical changes
 Spinal stenosis with the growth of osteophytes.
 Hypertrophy of the inferior articular process
 Disc herniation
 Bulging of ligamentum flavum
 These anatomical changes result in neurogenic
claudication (NC).
 NC include:
 Lower back pain
 Leg pain
 Numbness and motor weakness of lower extremities that
worsens with upright stance and walking and
 Improves with sitting and supine positioning
Impact of activity and occupation
 Driving
 High body mass index
 Daily spine loading – twisting, turning and lifting heavy
objects
Physiotherapy
 Compared to pain medication and surgery = best
intervention.
 Especially exercises that focus on stretching and
strengthening.
 TENS – not for long term pain relief.
 Myofascial therapy and joint manipulation also very
successful.
Terminology
 Arthritis of the spine: This affects the joints that connect
the vertebrae, namely the facet joints.
 Degenerative disc disease: This affects the intervertebral
discs, which begin to loose water and elasticity over time .
 Spinal stenosis: Gradual narrowing of the spinal canal of
foramina, which are passageways between the vertebra that
allow nerve roots to exit the spine.
