- Forward flexion = Schober’s Test
Schober’s test?
- Mark 5cm below and 10cm above levels of PSIS (sacral dimples, approx S2)
- Maximum flexion should lengthen line by >=5cm
Back exam special tests?
- Measure true and apparent leg lengths (scoliosis –> discrepancy)
- Sacroiliitis test = lateral compression, stretch (adduction of hip with hip and knee flexed)
- Straight leg raise = demonstrates lumbosacral nerve root irritation, record angle at pain onset
Straight leg raise aka?
Lasegue’s sign
Quick neuro assessment of lower limb?
- Power = L4 (foot inversion and dorsiflexion), L5 (great toe dorsiflexion, S1 (foot eversion and plantarflexion)
- Reflexes = S1 (Ankle)
- Sensation = L5 (great toe and medial dorsum), S1 (little toe and lateral sole)
Back exam completion?
- Complete neuro examination of lower limb, esp. perineal sensation
- Consider a PR = excludes a cauda equina compression
Pathophysiology of lumbar disc herniation?
- Pre-existing lumbar spondylosis
2. Rupture of annulus fibrosus with herniation of nucleus pulposus into spinal canal
Lumbar disc herniation risk factors?
- Physiological = age, poor posture, poor aerobic fitness
- Occupational = heavy manual labour, frequent bending/lifting/twisting, repetitive/static work postures
- Psychosocial = depression
Mx of lumbar disc herniation?
- Conservative
- Medical
- Surgical
Conservative mx of lumbar disc herniation?
- Max 2d bed rest
- Education = keep active, how to lift
- Physio = back to school
4 .Psychosocial issues er: chronic pain and disability - Warmth
Medical mx of lumbar disc herniation?
- Analgesia = paracetamol +/- NSAIDs +/- codeine
- Muscle relaxant = low dose diazepam (short term)
- Facet joint injections
Surgical mx of lumbar disc herniation?
- Percutaneous microdiscectomy
- Endoscopic discectomy
- Hemilaminotomy + discectomy
Indications for surgical mx of lumbar disc herniation?
- Progressive neurological deficit
- Severe incapacitating pain
- Failure of non-surgical options
