Can a Broken Bone Cause High White Blood Cell Count? | Recovery Timeline

How Broken Bones Can Lead to High White Blood Cell Count

When you break a bone, your body reacts by kicking your immune system into overdrive. Part of this immune response involves increasing production of white blood cells to help fight infection and begin the healing process.

This natural reaction can often lead to high white blood cell count after a fracture. Learn what causes this spike, if you should worry, and how doctors monitor your levels throughout recovery.

Overview of High White Blood Cell Count

Also called leukocytosis, high white blood cell (WBC) count refers to having more disease-fighting WBCs circulating in your bloodstream than normal.

Your WBCs, made up of cells like neutrophils and lymphocytes, serve as powerful weapons against invading viruses and bacteria. So your body ramps up WBC production to tackle infections and repair damaged tissue.

Normal ranges differ slightly by factors like race, age and gender:

• Adult counts: 3,800-10,500 white blood cells per microliter (cells/mcL)
• Child counts: 5,000-19,500 cells/mcL

Causes of High White Blood Cell Count

Many factors can trigger a spike in leukocytes. When levels rise in response to illness or injury, it signifies your body combatting infection or healing wounds. Common causes include:

• Bacterial infections Your body produces more neutrophils and lymphocytes to destroy invading bacteria.
• Viral infections Viral illnesses prompt lymphocytes to multiply and build antibodies.
• Inflammation Swelling triggers chemical signals telling leukocytes to accumulate.
• Tissue damage or injuries WBCs rush to wounds to prevent infection and repair damage.
• Intense exercise Vigorous workouts cause a temporary leukocytosis.
• Emotional/physical stress Stress hormones stimulate WBC response.
• Medications Corticosteroids and hormones elevate levels.
• Autoimmune disorders Diseases like rheumatoid arthritis trigger high levels.
• Bone marrow diseases Disorders like leukemia disrupt normal blood cell production.

High White Blood Cell Count After a Fracture

Breaking a bone ranks among top reasons for temporary leukocytosis. When bone snaps, the jagged edges tear blood vessels and muscle fibers. This traumatic tissue damage triggers localized swelling, inflammation, and bleeding.

Your body reacts by sending neutrophils and lymphocytes to prevent infection while the site heals. Macrophages also accumulate to clear out damaged tissue and kickstart the bone regeneration process.

In most cases of broken bones, having up to 30,000 cells/mcL immediately after fracture remains fairly normal and subsides with time.

Complications from Bone Breaks Leading to High Levels

While moderate high white blood cell counts commonly accompany fractures as your body repairs itself, extremely high levels can occasionally stem from complications like:

• Bone infection (osteomyelitis) If bacteria invades the broken bone or surrounding tissue, rampant infection causes WBCs to skyrocket further as your body battles the pathogens spread.
• Slow healing wounds Chronic inflammation from injuries struggling to heal triggers persistently elevated leukocyte counts.

Monitoring White Blood Cell Levels After Fracture

Doctors closely track your white blood cell counts before and following any broken bone. Monitoring levels helps discern normal short-term spikes from more serious sustained elevations requiring further treatment.

Testing Frequency

Typical testing frequency includes:

• At emergency room check-in
• During hospital stay after surgery to pin or plate the broken bone
• At follow-up bone check appointments (after 2 weeks, 6 weeks, 3 months, 6 months)
• During physical therapy
• Within 1-2 weeks if pain or other issues arise

Diagnosing Cause of High White Blood Cell Count

To deduce why counts remain consistently high, your physician may order additional blood tests like:

• Complete blood count (CBC) Checks levels of all blood components like red cells, platelets, hemoglobin.
• Blood cultures Detects presence of infection-causing pathogens.
• Bone biopsy Involves sampling bone marrow to test for cancer cells.

You may also undergo imaging scans like X-rays, CTs or bone scans for closer inspection of fracture site.

Tracking Timeline for Elevated Levels Post-Fracture

When checking blood tests after a break, doctors expect elevated WBC counts to rise and fall along this general timeline as healing progresses:

• First 3 days Levels rapidly shoot upward, peaking around days 2-3 post-fracture.
• 1 week Numbers start dropping but often still remain on higher side.
• 2 weeks Counts decrease closer to normal baseline range.
• 6 weeks WBC elevation continues to wane as fracture stabilizes.
• 3-6 months Levels level off, signaling bone has fully healed.

What Does Persistently High White Blood Cell Count Mean?

When detected early on after a fracture or surgery, spiking leukocyte numbers fall within expected parameters. But if levels fail to lower after the first couple weeks or climb higher without explanation, it may indicate:

• An underlying infection like osteomyelitis (bone infection).
• Poor bone healing with chronic inflammation from inadequate stabilization or fixation issues.
• Bone cancer growth possibly stimulated by fracture trauma.

In these instances, promptly treating the root cause helps alleviate symptoms like unrelenting pain and guides WBC counts back to normal.

Osteomyelitis

This serious bone infection arises when bacteria enters fractured bone tissue during injury. Warning signs beyond extreme leukocytosis include:

• Fever and flu-like illness
• Swelling, redness, warmth around fracture site
• Drainage of pus from wound
• Bone pain that worsens over time

Aggressive IV antibiotic treatment for 6-12 weeks usually clears infection. In advanced cases, repeat surgery may be needed to scrape out (debride) dead bone tissue.

Nonunion Fractures

With nonunion (or malunion) fractures, broken bones fail to correctly heal. This leads to destabilization, chronic pain and inflammation. High WBCs signal your bodys continuous failed effort to stimulate healing.

Getting fracture alignment corrected with revision surgery helps stabilizes the break for proper mending.

Bone Cancer

In extremely rare cases, persistently high leukocytosis combined with worsening pain/swelling may raise red flags for fracture-associated bone cancer like:

• Osteosarcoma Aggressive malignant bone tumor most common in kids/teens.
• Chondrosarcoma Cancer forming in cartilage cells, predominantly in adults.

Catching concerning changes via blood tests and scans quickly is key. This allows swift tumor removal surgery before cancerous cells spread elsewhere.

Recovering from High White Blood Cell Count

As your fracture site heals free of infection and inflammation subsides, white blood cell levels gradually fall back within normal parameters (5,000-10,000 cells/mL).

Aiding your bodys return to homeostasis includes:

• Taking prescribed antibiotics to fully treat infections
• Undergoing follow-up surgeries to restabilize fractures or remove bone tumors
• Sticking to RICE recovery protocol rest, ice, compression, elevation
• Eating nutritious anti-inflammatory diet
• Avoiding reinjury through physical therapy
• Managing pain/swelling with ibuprofen and ice packs
• Quitting smoking to maximize bone health and healing capacity

In most cases of broken bones, this comprehensive healing approach brings high white blood cells back down within 1-2 months post-injury.

Key Takeaways

High white blood cell counts commonly accompany fractures as your bodys normal inflammatory reaction works to prevent infection and mend damaged tissue.

Levels typically peak within the first 72 hours then gradually decline as healing progresses over the ensuing weeks. Monitor for complications if counts remain consistently elevated or continue rising.

Closely tracking your blood cell counts helps diagnose and promptly treat underlying issues like osteomyelitis or bone cancer. This supports recovery so levels stabilize back to normal baselines.
