Outpatient prevention of leg clots in patients with ankle fractures or Achilles tendon ruptures

Prevention of Thromboembolism and Failed Healing During Lower Limb Immobilization - Multicenter Study With Adjuvant Intermittent Pneumatic Compression Therapy

Not applicable Interventional Karolinska University Hospital · NCT03259204

This study tests if a special air compression treatment can help prevent blood clots and improve healing in patients with ankle fractures or Achilles tendon ruptures who are in a cast.

What this trial studies

This clinical trial investigates the effectiveness of intermittent pneumatic compression (IPC) therapy in preventing venous thromboembolism (VTE) and improving healing in patients with ankle fractures or Achilles tendon ruptures who are immobilized. The study will enroll 1,400 patients and compare the outcomes of those receiving IPC therapy to those receiving standard plaster cast treatment. Participants will undergo clinical examinations and Doppler ultrasound screening for VTE, ensuring safety and timely intervention if necessary. The goal is to establish a new standard of care for outpatient management of these injuries.

Who should consider this trial

Good fit: Ideal candidates are individuals with acute unilateral Achilles tendon ruptures or isolated ankle fractures who can start treatment within 10 days in a hospital setting.

Not a fit: Patients with known kidney disorders, heart failure with pitting edema, malignancies, bleeding disorders, or those who are pregnant will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could significantly reduce the incidence of VTE and improve healing outcomes for patients with leg immobilization.

How similar studies have performed: While IPC is commonly used in hospitalized patients, its application in outpatient settings for this specific purpose is novel and has not been extensively tested.
