Sudden back pain in osteoporotic adult, suspected vertebral compression fracture
Recommended: MRI Thoracic / Lumbar Spine (STIR for acute edema) is the preferred imaging study for sudden back pain in osteoporotic adult, suspected vertebral compression fracture. MRI distinguishes acute (edema, T2 bright) from chronic (no edema, fatty marrow).
Recommended study
MRI Thoracic / Lumbar Spine (STIR for acute edema)
MRI distinguishes acute (edema, T2 bright) from chronic (no edema, fatty marrow). Critical for vertebroplasty / kyphoplasty selection.
If the default doesn't apply
MRI contraindicated
NM
Tc-99m bone scan + targeted CT
IV contrast
Concern for malignancy / atypical
MRI
MRI with contrast + biopsy
IV contrast
Watch-outs
Burst fracture vs simple compression
Retropulsion of fragment into canal changes management; CT for bony detail.
Atypical features (lytic destruction, mass)
Suspect metastasis or myeloma — biopsy before vertebroplasty.
Pearls
- Vertebroplasty / kyphoplasty effective for painful acute osteoporotic VCFs.
- Multiple VCFs in osteoporotic patient → bone health work-up (DEXA, bone markers).
- FRAX (Fracture Risk Assessment Tool) for 10-year fracture risk estimation; VFA on DEXA detects prevalent vertebral fractures and is recommended for at-risk patients.
