Multiple Fractures: The Workup to Ask For

Multiple fractures in adults can arise from a single high-energy trauma or reflect underlying bone disease. When you see two or more breaks in one person—especially with minimal trauma—it’s important to dig deeper. Proper evaluation not only guides immediate treatment but also uncovers any hidden conditions that weaken bone. Below is a practical, step-by-step workup to discuss with your healthcare provider.

Common Causes of Multiple Fractures in Adults

Understanding the reasons behind multiple fractures helps tailor tests and treatment. Key causes include:

• High-energy trauma
 – Motor vehicle collisions
 – Falls from height
 – Sports or industrial injuries

• Pathologic fractures (weakened bone from disease)
 – Osteoporosis (age- or medication-related)
 – Metastatic cancer (breast, prostate, lung)
 – Multiple myeloma
 – Primary bone tumors (e.g., osteosarcoma)
 – Metabolic bone disorders (hyperparathyroidism, osteomalacia)

• Infection
 – Osteomyelitis can erode bone, leading to breaks

• Medication-related
 – Long-term steroids
 – Aromatase inhibitors
 – Proton-pump inhibitors (impact calcium absorption)

• Genetic and nutritional factors
 – Vitamin D deficiency
 – Rare disorders (osteogenesis imperfecta, Paget’s disease)

• Non-accidental injury
 – Domestic violence or elder abuse

Initial Clinical Assessment

1. Gather a focused history

   • Trauma details: mechanism, height of fall, direct blow
   • Bone health: prior fractures, osteoporosis risk (age, family history, lifestyle)
   • Cancer history: personal or family, weight loss, night pain
   • Medications: steroids, anticoagulants, cancer treatments
   • Nutrition and lifestyle: calcium/vitamin D intake, smoking, alcohol

2. Perform a targeted physical exam

   • Inspect: swelling, deformity, bruising
   • Palpate: point tenderness, gaps in bone continuity
   • Neurovascular check: pulses, sensation, motor function
   • Screen for other injuries: head, chest, abdomen, pelvis

3. Evaluate for “red flags”

   • Pain at rest or night pain
   • Unexplained weight loss
   • Fever or signs of infection
   • History of minor trauma causing major breaks

Imaging Studies

Accurate imaging confirms fractures and guides further tests:

• Plain radiographs (X-rays)
– First step for any suspected fracture
– Obtain two views (e.g., anteroposterior and lateral)

• Computed tomography (CT)
– Detailed view of complex or intra-articular fractures
– Helpful for pelvic and spinal injuries

• Magnetic resonance imaging (MRI)
– Best for occult (hidden) fractures not seen on X-ray
– Evaluates bone marrow edema, soft tissue, spinal cord

• Bone scan (radionuclide imaging)
– Detects multiple stress or insufficiency fractures
– Useful when MRI is contraindicated

Laboratory Evaluation

Lab tests help identify metabolic bone disease or malignancy:

Basic panel:
• Complete blood count (CBC)
– Anemia may suggest chronic disease or multiple myeloma
• Comprehensive metabolic panel (CMP)
– Kidney function, electrolytes

Bone-specific tests:
• Serum calcium, phosphate, alkaline phosphatase (ALP)
• 25-hydroxyvitamin D
• Parathyroid hormone (PTH)

Markers for malignancy:
• Serum protein electrophoresis (SPEP) and urine protein electrophoresis (UPEP)
– Screens for multiple myeloma
• Tumor markers if clinical suspicion (e.g., PSA in prostate cancer)

Inflammatory and infection markers:
• Erythrocyte sedimentation rate (ESR)
• C-reactive protein (CRP)

Additional tests as indicated:
• Thyroid-stimulating hormone (TSH)
• Sex hormones (estradiol, testosterone)
• Bone turnover markers (osteocalcin, CTX)

---

Bone Density Assessment

When osteoporosis or osteopenia is suspected, a bone mineral density (BMD) scan (DEXA) helps quantify fracture risk:

• T-score ≤ –2.5 confirms osteoporosis
• T-score between –1.0 and –2.5 indicates osteopenia

A DEXA scan guides preventive strategies—lifestyle changes, calcium/vitamin D supplementation, and medications (bisphosphonates, denosumab).

Advanced Diagnostics

If lab and imaging raise concern for cancer or rare bone disease:

• Bone biopsy
– Confirms malignancy or specific infections
• Genetic testing
– Suspect inherited bone fragility disorders
• Endocrine referral
– Complex metabolic bone disease

---

Putting It All Together

1. Stabilize acute fractures and address pain.
2. Review imaging to classify fractures (open vs. closed, displaced vs. nondisplaced).
3. Order labs and bone density testing based on initial findings.
4. Consult specialists as needed: orthopedics, endocrinology, oncology, infectious disease.
5. Initiate treatment for underlying bone disease—calcium/vitamin D, pharmacotherapy, lifestyle modifications.
6. Plan rehabilitation: physical therapy, fall prevention, home safety assessment.

When to Seek Immediate Help

If you notice any of the following, speak to a doctor right away:

• Loss of limb sensation or movement
• Signs of infection (fever, redness, draining wound)
• Uncontrolled pain
• Sudden shortness of breath or chest pain (possible fat embolism or DVT)

Final Thoughts

Multiple fractures in adults shouldn’t be dismissed as “just bad luck.” A systematic workup uncovers hidden risks and guides treatments that strengthen bone and prevent future breaks. Always discuss any serious or life-threatening concerns with a qualified healthcare professional. Your doctor can interpret test results, refine your diagnosis, and tailor a safe, effective care plan.
