Basic Spine MSK Exam Flashcards
spondylolysis
fracture of pars interarticularis (spottie dog)
spondylolisthesis
anterior displacement of one vertebrae on another
basic spine exam do what?
assess appearance, palpate, check ROM, basic strength, basic reflexes, basic sensory exam, any special tests
appearance: looking for what?
symmetry, scoliosis, scapular winging, cervical/lumbar lordosis, thoracic kyphosis, cafe au lait spots (neurofibromatosis), atrophy
palpate what/where?
spinous processes/interspaces, paraspinal muscles, cervical spine (cervical musculature) lumbar spine
cervical spine landmarks?
hyoid bone- C3
thyroid cartilate- C4-5
first cricoid ring- C6
most prominent spinous process- C7
lumbar spine landmarks?
top of iliac crest, L4-5
PSIS, S2
cervical spine ROM?
rotation: 70
flexion: 45
extension: 55
sidebending: 40
lumbar spine ROM?
flexion: 75
extension: 30
lateral bending: 35
rotation
pathologic reflexes (signs of upper motor neuron process)
hoffman: passive rapid flexion of distal middle finger (+ = flexion of thumb, index finger)
babinski: stroking sole of foot resulting in great toe extension and toe spreading
special tests?
straight leg raise, femoral stretch test, spurling test (cervical spine extension etc = ipsi radicular stx), Lhermitte (electric shock sensation in limbs with cervical flexion)
lumbar strain history + etiology
axial low back pain after acute injury. muscle disruption from excessive stretch/tension
lumbar strain exam + treatment
localized muscle tenderness, reduced ROM. no imaging, relative rest, NSAIDs
osteoarthritis (facet joints) history + etiology
axial low back pain w gradual onset. d/t gradual degenerative changes/OA to facet joints. > 55
osteoarthritis (facet joints) exam + treatment
nonspecific, pain provoked with active extension, relieved with flexion. no imaging, NSAIDs, mild analgesics. PT.
radiculopathy history + etiology
pain & possible numbness/weakness in limb > axial spine. disc herniation more common.
radiculopathy exam + treatment
SLR or Spurling +, neuro deficits (weakness, decreased reflex, reduced sensation). MRI, maybe EMG. relative rest, PT, NSAIDs
lumbar stenosis history
slowly progressive back and unilateral/bilateral leg pain. shopping cart sign. differentiate from vascular claudication.
lumbar stenosis etiology
narrowing of spinal canal d/t disc herniation/protrusion, ligamentum flavum thickening, osseous thickening of bone/facet joint, spondylolisthesis
lumbar stenosis exam
nonspecific. possibly flexed standing posture, reduced lumbar lordosis
lumbar stenosis treatment
MRI, maybe CT or EMG. NSAIDs, PT, use of walker
cervical myelopathy history + etiology
pain, numbness, weakness in arms &/or legs, balance and gait difficulties, bowel/bladder dysfunction. d/t cervical canal stenosis w spinal cord compression
cervical myelopathy exam + treatment
arm and/or leg weakness, UMN signs. MRI, surgical decompression. no role for nonoperative treatment.
compression fracture history + etiology
usually sudden thoracic or lumbar pain, often little to no trauma. osteoporosis relation in older patients. younger consider malignancy, multiple myeloma. 1/3 asymptomatic.
compression fracture exam
tender over spinous processes, paraspinals. worse with lumbar flexion. better with lumbar extension. normal neuro exam.
compression fracture treatment
imaging: plain x-rays, poss MRI or CT. DEXA scan for osteoporosis. different if malignancy considered. bracing. PT. consider vertebroplasty
ankylosing spondylitis history
onset of low back pain < age 40, insidious, better with exercise, pain at night and on waking, not improved with rest
ankylosing spondylitis etiology
inflammatory spondyloarthropathy, usually sacroiliitis initially. can be assoc w uveitis, inflammatory bowel disease, psoriasis
ankylosing spondylitis exam
reduced lumbar ROM, often tender to palpation over sacroiliac joints with positive joint provocative tests
ankylosing spondylitis treatment
imaging: plain x-rays, earliest finding sacroiliitis. later, bamboo spine.
labs: HLAB27, CRP, sed rate.
meds: NSAIDs, possibly anti-TNF agents. PT, spine extension
cauda equina syndrome history
leg pain, numbness, weakness, saddle anesthesia, bowel/bladder dysfunction
cauda equina syndrome etiology
large herniated disc compressing cauda equina most common
cauda equina syndrome exam + treatment
reduced or absent reflexes, weakness, decreased rectal tone. surgical emergency!
