Abstract: Objective: To investigate the relationships between incidence of deep venous thrombosis (DVT) and fracture site, fracture type and waiting time for operation after lower limb fracture. Methods: The clinical data of 2043 lower limb fracture patients were retrospectively analyzed and recorded the incidence of DVT of different fracture site, fracture type and waiting time for operation. Results: Among 2043 lower limb fracture patients, the incidence of DVT was 8.92% (182/2043). The incidence of DVT from high to low at different part of fracture was proximal femoral fracture, femoral shaft fracture, distal femoral fracture, tibial plateau fracture, fractures of tibia-fibula shaft, ankle joint fracture, patella fracture, foot fracture. The incidence of DVT of fracture of three or more parts, waiting time for operation more than 4 days (including 4 day) were respectively higher than single fracture and two parts fracture, as well as waiting time for operation less 4 days (P<0.05). Conclusions: Orthopedists should pay more attention on DVT high incidence site and multiple fracture, in order to take targeted diagnosis and treatment as early as possible. The fracture patients with long waiting time for operation should be given corresponding treatment to decrease the incidence of DVT.
