Which lumbar disc level is most commonly herniated?
L3 - L4
L1 - L2

Vertebral body
Lamina
The vertebral body is the anterior column of the vertebra and forms the front boundary of the spinal canal.
A patient with neurogenic claudication likely has which pathology?
Lumbar spinal stenosis

Herniated cervical disc
Scoliosis
Lumbar spinal stenosis leads to narrowing of the canal, causing neurogenic claudication worsened by walking and relieved by flexion.

Plain radiograph
MRI with contrast
CT scan
Ultrasound
Gadolinium-enhanced MRI provides high sensitivity and specificity for identifying epidural abscesses and their extent.
On oblique lumbar spine X-ray, a 'Scotty dog' appearance with a collar indicates:
Pars interarticularis defect
Disc degeneration
Vertebral fracture
Facet hypertrophy
A defect in the pars interarticularis appears as a collar or neck break on the Scotty dog sign, indicating spondylolysis.
The AO Spine classification system for thoracolumbar fractures categorizes injuries based on what main criteria?
Fracture morphology
Patient age
Bone density
Symptom duration
The AO Spine classification focuses on fracture morphology (compression, burst, translation) to guide treatment and prognosis.
Which Modic change on MRI is characterized by vertebral endplate edema on T2-weighted images and hypointensity on T1-weighted images?
Type IV
Type III
Type I
Type II
Modic type I changes reflect active inflammatory edema that appears bright on T2-weighted and dark on T1-weighted MRI sequences.
According to the Modified New York Criteria, diagnosis of ankylosing spondylitis requires radiographic sacroiliitis plus at least how many clinical features?
One
Four
Three
Two
The Modified New York Criteria require radiographic sacroiliitis plus at least one clinical feature such as chronic back pain, reduced spine mobility, or chest expansion limitation.
Which MRI finding helps distinguish an osteoporotic compression fracture from a malignant vertebral compression fracture?
Low signal on STIR images
Uniform marrow replacement
Preserved normal fatty marrow signal
Presence of paravertebral soft tissue mass
Osteoporotic fractures typically preserve normal fatty marrow signal on T1-weighted images, unlike malignant lesions which replace marrow and cause signal loss.
The most common causative organism in vertebral osteomyelitis is:
Pseudomonas aeruginosa
Escherichia coli
Mycobacterium tuberculosis
Staphylococcus aureus
Staphylococcus aureus is the most common pathogen in pyogenic vertebral osteomyelitis, often spreading hematogenously to the spine.
Which condition narrows the intervertebral foramina leading to nerve root compression?
Facet joint ankylosis
Foraminal stenosis
Neural arch hypertrophy
Central canal stenosis
Foraminal stenosis is characterized by narrowing of the intervertebral foramen, leading to compression of exiting nerve roots and radicular pain.
Standard initial management for acute non-specific low back pain without red flags includes:
Bed rest for 4 weeks
Immediate MRI
High-dose opioids
NSAIDs and activity modification
Acute non-specific low back pain without red flags is best managed initially with NSAIDs and encouraging normal activity to promote recovery.
A positive Babinski sign indicates dysfunction of which type of motor pathway?
Cerebellar
Peripheral nerve
Lower motor neuron
Corticospinal (upper motor neuron)
A positive Babinski sign indicates upper motor neuron (corticospinal) tract dysfunction, presenting as extensor plantar response.
Type II isthmic spondylolisthesis is primarily due to what defect?
Degenerative facet joint hypertrophy
Stress fracture of pars interarticularis
Congenital pedicle agenesis
Traumatic vertebral body fracture
Type II isthmic spondylolisthesis results from a stress fracture in the pars interarticularis, allowing forward slippage of the vertebral body.
Which clinical feature is most characteristic of cauda equina syndrome?
Unilateral leg pain
Hyperreflexia in lower limbs
Clonus
Bowel and bladder dysfunction
Cauda equina syndrome involves compression of multiple nerve roots, leading to bowel/bladder dysfunction, saddle anesthesia, and requires urgent decompression.
The artery of Adamkiewicz typically arises between which vertebral levels?
L1 - L3
T2 - T4
T9 - T12
T5 - T7
The artery of Adamkiewicz most commonly arises between T9 and T12 on the left side, supplying the lower two-thirds of the spinal cord.
The Thoracolumbar Injury Classification and Severity Score (TLICS) incorporates fracture morphology, neurological status, and what additional factor?
Patient age
Posterior ligamentous complex integrity
Inflammatory markers
Bone mineral density
TLICS includes evaluation of the posterior ligamentous complex integrity to assess stability alongside fracture morphology and neurological status.
A TLICS score of 5 indicates what management recommendation?
Bed rest only
Surgical stabilization
Conservative treatment
High-dose steroids
A TLICS score of 5 or more typically warrants surgical stabilization, as it indicates instability or neurological compromise.
In spondylolisthesis, instability is radiographically defined as more than how many degrees of angular rotation or millimeters of translation?
11° or 3.5 mm
5° or 2 mm
20° or 5 mm
15° or 10 mm
Radiographic criteria for instability in spondylolisthesis include >11° angular rotation or >3.5 mm anterolisthesis measured on flexion-extension films.
Which MRI sequence is most sensitive for detecting cerebrospinal fluid leaks in suspected spinal dural tears?
Gradient echo T2*
Proton density
Heavily T2-weighted MR myelography
T1-weighted with contrast
Heavily T2-weighted MR myelography accentuates CSF signal, allowing visualization of leaks and dural tears without direct contrast injection.
