Deep vein thrombosis (DVT) — blood clot formation in the deep veins of the lower leg — is a recognized complication of foot and ankle surgery, particularly procedures requiring non-weight-bearing immobilization. While the absolute incidence of symptomatic DVT after foot and ankle surgery is lower than after hip and knee arthroplasty (1–3% vs. 10–15%), pulmonary embolism (PE) from DVT is potentially life-threatening, and understanding DVT prevention strategies helps patients and their care teams minimize this risk.
Risk Stratification
High-risk procedures and patient factors for foot/ankle surgical DVT: hindfoot and ankle procedures with prolonged non-weight-bearing (calcaneal osteotomy, triple arthrodesis, Achilles repair, ankle ORIF) — more risky than forefoot procedures where early weight-bearing is possible; patient risk factors: prior DVT or PE (highest risk — anticoagulation is mandatory), active malignancy, inflammatory bowel disease, thrombophilia (factor V Leiden, prothrombin gene mutation), obesity (BMI >35), age >60, combined oral contraceptive use, prolonged air travel within 2 weeks of surgery, and venous insufficiency. Low-risk patients undergoing forefoot procedures with early protected weight-bearing: mechanical prophylaxis only (ankle pump exercises, early mobilization).
Prevention Strategies
Mechanical prophylaxis: ankle dorsiflexion-plantarflexion ‘pump’ exercises begin immediately post-operatively (20 repetitions every hour while awake) — the calf muscle pump is the primary driver of deep venous return; sequential compression devices (SCDs) applied to the non-operative extremity during surgery and the first 24–48 hours post-operatively. Pharmacological prophylaxis: aspirin 81–325mg daily for low-to-moderate risk patients undergoing non-weight-bearing hindfoot surgery — emerging evidence supports aspirin efficacy with lower bleeding risk than anticoagulants; low-molecular-weight heparin (LMWH — enoxaparin) or direct oral anticoagulants (DOACs — rivaroxaban, apixaban) for high-risk patients or those with prior VTE history. Warning signs requiring immediate evaluation: unilateral calf swelling, warmth, and erythema (DVT); sudden dyspnea, chest pain, or hypoxia (PE). Dr. Biernacki at Balance Foot & Ankle stratifies DVT risk before all foot and ankle surgical procedures and prescribes individualized prophylaxis protocols.

When to See a Podiatrist
Many foot conditions can be managed conservatively at home, but some require professional evaluation. See a podiatrist promptly if you experience:
- Pain that persists for more than 2 weeks despite rest
- Swelling, redness, or warmth that isn’t improving
- Numbness, tingling, or burning in the feet
- A wound or sore that is not healing within 2 weeks
- Any foot concern if you have diabetes or poor circulation
- Nail changes that suggest fungal infection or other problems
At Balance Foot & Ankle, our three board-certified podiatrists — Dr. Tom Biernacki, Dr. Carl Jay, and Dr. Daria Gutkin — provide comprehensive foot and ankle care at our Howell and Bloomfield Township offices. Most insurance plans are accepted.

Frequently Asked Questions
How do I know if I sprained or broke my ankle?
Both cause pain, swelling, and difficulty walking. Key differences: fractures often cause more immediate severe pain, tenderness directly over bone (not just ligament), and inability to bear any weight. X-rays and the Ottawa Ankle Rules help determine if imaging is needed.
How long does an ankle sprain take to heal?
Grade I (mild): 1–2 weeks. Grade II (moderate): 3–6 weeks. Grade III (complete tear): 2–3 months. Chronic instability from improperly treated sprains can persist and may require surgery.
What is the best treatment for a sprained ankle?
RICE protocol (Rest, Ice, Compression, Elevation) for the first 48–72 hours, followed by protected weight-bearing as tolerated. Physical therapy rehabilitation is critical for high-grade sprains to restore strength and proprioception and prevent chronic instability.
