Conditions for 16/01/23 Flashcards
(138 cards)
OA aetiology
- Increased age (takes years to develop)
- Incongruent Jts
- Relationship between stress on articulate cartilage + ability of cartilage to withstand stress
Obesity
OA clinical features
- P starts insidiously + increases slowly over few months
- Aggravated by exertion
- Relieved by rest
- Stiffness usually worse after rest
- Swelling, crepitus, deformity, tenderness, muscle wastage, reduced ROM
OA X-ray findings
- Osteophyte formation
- Jt space narrowing
- Subchondral sclerosis (thickening of bone in affected Jt)
- Cysts
OA pathophysiology
- Softening of cartilaginous surfaces
- Become frayed
- Eventually worn away exposes underlying bone in areas of great stress
- Bone can develop cysts
- Surrounding trabeculae can become thickened
- Ossification produces bony growths
OA cautions
Exercise
Posture
Knees, hips, hands, spine
OA management
- Pharmacological
- Braces/support
- Supplements
- Surgery
- Osteopathy- increased ROM, flexibility
Lumbar spondylosis aetiology
- No specific cause
- Associated with ageing, degeneration of Jts, ligaments, discs, natural wear and tear
Degeneration of intervertebral discs in Jts in lower back- wear + tear
Risks- OA, poor posture, obesity
Lumbar spondylosis clinical features
- P in low back
- Often worse when standing or walking, relieved when sitting or bending forward
- P spread to thighs
- Tight hamstrings
Lumbar spondylosis X-ray finding
- Reactive sclerosis
- Narrowing of intervertebral disc space e
- Deviation or step off signs of SPs
- Degeneration of facet Jt
Lumbar spondylosis pathophysiology
- Occurs as result of new bone formation in areas where annular ligament is stressed
Degen of intervertebral discs + Its in low back
Forms bony spurs, narrowing disc space, which can put pressure on N and cause P
Cautions lumbar spondylosis
- Avoid sitting for more than 30 mins at a time
- Eating diet high in sugar, processed and refined foods (inflammatory)
Lumbar spondylosis management
- Pain relieves
- NSAIDs
- Muscle relaxants
PT- exercises to improve strength + flexibility
Surgery- alleviate pressure on nerves, remove bony spurs
Chronic- requires follow up care
Lumbar facet degeneration aetiology
- Alternate spinal conditions which change the way facets align
- OA leading cause
Lumbar facet degeneration clinical features
- P or tenderness in low back
- Stiffness in surrounding structures
- Difficulty with certain movements, e.g. standing up straight or getting up from a chair
Lumbar facet degeneration X-ray
- Narrowing of disc space
- Subchondral sclerosis
- Osteophytes
Not specific to facet irritation, not all will show these changes
Lumbar facet degeneration pathophysiology
- Facet Jt comprises posterior element of ‘three-Jt complex’
- Intervertebral disc is anterior part
- As disc degenerates more load will shift posteriorly and facet Jt OA will subsequently develop
- Rarely occurs without disc degeneration
Lumbar facet degeneration cautions
Advances age or osteoporosis- increase risk of fracture
Pregnancy- certain treatment not safe
Lumbar facet degeneration management
- Physio and pharmacology (NSAIDs) first line treatment
- Facet Jt injection, medial branch block
Spondylolithesis aetiology
Failure of facet and laminae locking mechanism
Degenerative- wear and tear
Dysplastic- congenital
Isthmic- fracture to pars interarticularis (bone that covers upper + lower facet)- cause forward slip to L5/S1
Pathologic- slip due to weakness of bones
Spondylolithesis clinical features
- Usually painless
- L4/5/S1
- Intermittent back ache, may be exacerbated by exercise or strain
- Step deformity
- Normal ROM in younger Pts
Spondylolithesis X-ray findings
Slippage of vertebra from spinal column
Shows if congenital or acquired
CT/MRI for surrounding structures
Spondylolithesis pathophysiology
- Normal laminae and facet locking mechanism fails
- Causes forward slippage (listheis) of vertebral body
L4/5/S1 most common
Spondylolithesis cautions
Cauda equina- numbness in saddle, los =s of bowel or bladder control
Spondylolithesis management
Conservative- NSAIDs, steroid injection
Surgery if grade 3/4, spinal fusion of veterbra to above, laminectomy
