Japanese Study: Incidence of venous thromboembolism and bleeding complications in orthopedic surgery



Orthopedic surgery of the lower extremity including total knee arthroplasty (TKA), total hip arthroplasty (THA), and hip fracture surgery (HFS) are widely considered to carry a high risk of developing deep venous thrombosis (DVT) and venous thromboembolism (VTE) and a Japanese study has investigated this in 36,947 patients who had undergone orthopedic surgeries.

The researchers Fuji TAkagi MAbe YOda EMatsubayashi DOta K5, Kobayashi MMatsushita YKaburagi JIbusuki KTakita AIwashita M and Yamaguchi T are from 10 institutions in Japan. 



The source population of the database was derived from 100 acute-care hospitals.  13.6% of the patients ahd total knee arthroplasty. 10.4% for had total hip arthroplasty and 56.8% had hip fracture surgery, 1.5% for rupture of Achilles tendon and 18.0% for simple fracture of lower extremities.



The incidence for DVT and venous thromboembolism (pulmonary) and bleeding events by type of surgery was :


Total knee arthroplasty:  DVT 1.3%,  VTE 0.2% and bleeding evetns 1.0%.


Total hip arthroplasty:  DVT 0.9%, VTE 0.2% and bleeding events 1.1% 


Hip fracture surgery:  DVT 0.4%, VTE 0.1% and bleeding events 1.8%



The authors just report these findings as an audit for their Japanese Orthopedic Surgery population.
