About This Page

This is a clinician-written, evidence-based summary aligned to the USMLE Step 2 CK Content Outline. It is intended for medical students preparing for USMLE Step 2 CK. Management reflects current ACC/AHA, USPSTF, and APA guidelines. Always cross-reference with UpToDate, institutional protocols, and clinical judgment.

Key points

  • Acute focal midline back pain after minimal trauma in osteoporosis
  • X-ray can diagnose height loss; MRI distinguishes acute vs chronic and evaluates malignancy/infection
  • Initial treatment is conservative: analgesia, mobilization, PT, selective bracing
  • Calcitonin can help short-term acute pain
  • A vertebral fragility fracture diagnoses osteoporosis and predicts future fracture

Overview

Osteoporotic vertebral compression fracture is a fragility fracture caused by reduced bone strength, usually after bending, lifting, coughing, or minor fall. It often affects thoracolumbar vertebrae.

Epidemiology

Most common osteoporotic fracture; risk rises with age, postmenopause, prior fracture, glucocorticoids, low BMI, smoking, alcohol, vitamin D deficiency, and hypogonadism.

Clinical Features

Symptoms
Acute focal back pain after minimal trauma
Pain worse with standing/walking/coughing and relieved lying down
Height loss or progressive kyphosis
Night pain/weight loss/cancer history suggests malignancy
Fever/bacteremia risk suggests infection
Signs
Focal midline vertebral tenderness
Thoracic kyphosis or height loss
Pain-limited mobility
Normal neurologic exam in uncomplicated fracture
Neurologic deficit is a red flag

Investigations

First-line
Focused clinical assessmentPattern recognition, red flags, functional impact, and targeted examination
Basic labs when indicatedCBC, CMP, ESR/CRP, CK, urinalysis, or disease-specific testing depending on suspected condition
Initial imaging when indicatedPlain radiographs or MRI/ultrasound based on suspected structural, inflammatory, infectious, or neurologic disease
Second-line
Disease-specific confirmatory testingAutoantibodies, HLA-B27, synovial fluid, nerve conduction studies, DEXA, or cultures as appropriate
MRI/ultrasound/CTUsed for early inflammatory disease, occult fracture, tendon tear, infection, or surgical planning
Screening before immunosuppressionTB, hepatitis, vaccination review, and baseline labs when biologic or high-risk therapy is planned
Specialist
Specialist referralRheumatology, orthopedics, infectious disease, ophthalmology, neurology, or spine surgery depending on red flags and disease severity
1
Initial management
  • Address red flags and emergencies first
  • Use guideline-directed first-line therapy matched to disease severity
  • Educate the patient and set functional goals
  • Use analgesia and rehabilitation when appropriate
2
Escalation
  • Escalate to specialist-directed therapy if severe, refractory, progressive, or organ-threatening disease
  • Use imaging, procedures, immunosuppression, antibiotics, or surgery according to diagnosis
  • Monitor response objectively and revise diagnosis if response is atypical
3
Prevention and follow-up
  • Manage comorbidities and medication toxicity
  • Vaccinate and screen when immunosuppression is used
  • Prevent disability, falls, fracture, infection, and functional decline

Complications

  • Functional impairment: Pain, weakness, stiffness, deformity, or disability depending on disease
  • Diagnostic delay: Missed infection, fracture, inflammatory disease, neurologic compromise, or organ-threatening complication
  • Medication toxicity: NSAID, steroid, antibiotic, anticoagulation, opioid, or immunosuppressive adverse effects
  • Chronic disease burden: Reduced quality of life, work impairment, deconditioning, and mental health impact
USMLE Step 2 CK Exam Tips
  • 1Older woman with sudden focal back pain after lifting = compression fracture
  • 2Initial imaging is plain x-ray
  • 3MRI if neurologic symptoms, malignancy/infection concern, or acuity uncertainty
  • 4Fragility vertebral fracture diagnoses osteoporosis regardless of DEXA
  • 5Calcitonin can be used short-term
  • 6Prolonged bed rest is harmful
