A new device for deep vein thrombosis prophylaxis in orthopaedic surgery: pneumatic foot compression.

Thromboembolic disease is a potentially fatal complication after high-risk orthopaedic surgery such as total joint arthroplasty and major trauma. Without prophylaxis, pulmonary embolism is known to occur in 1% to 2% of hospitalized patients. Pneumatic foot compression devices have recently been developed to increase lower extremity circulation and, as a result, are effective in thromboembolic disease prophylaxis. Recent studies in total hip and total knee arthroplasty have documented a statistically significant reduction in deep venous thrombosis using these devices. Interestingly, studies utilizing pneumatic foot compression have demonstrated a reduction in lower extremity edema both postoperatively and after significant lower extremity trauma. Pneumatic foot compression appears to be more applicable than the previous mechanical devices, and as a result, compliance appears to have improved.
