About this study
Deep vein Thrombosis (Deep Venous Thrombosis, DVT) and Pulmonary Embolism, Pulmonary Embolism, PE) both collectively known as Venous thromboembolism (VTE) (Venous Thrombus Embolism, VTE), is a common clinical disease, and tremendous harmful. Ankle fractures in patients requiring long-term bed braking, increase the incidence of lower extremity deep vein thrombosis, anticoagulant therapy as an important measures to prevent thrombosis in clinical widely accepted, however, the literature anticoagulation effect incision healing. Whether to strike a balance between the two, to develop a foot fracture in accordance with the Chinese characteristics of anticoagulant solution is we try to solve the problem. The purpose of this study is aimed at the use of oral anticoagulants and physical anticoagulant treatment knee far foot fracture patients randomized controlled studies in China.

What does the primary outcome measure?
the rate of venous thromboembolism (VTE) on 12th postoperative week (time frame: 12th postoperative week). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
