Background: The incidence of DVT in traumatic injuries is as high as 5-63%. An autopsy study found 20% death of PE and 65% of fatality of injured patients by DVT. Proximal femoral fracture are at a high risk of perioperative DVT and guidelines have recommended mechanical and pharmacological prophylaxis for patients undergoing surgery for hip fracture. But it remains controversial whether patients with proximal femoral fracture can benefit from thromboprophylaxis specially in Indian population. Our aim is to find out the role of enoxaparin in thromboprophylaxis, its adverse effects and surgery on different time span from date of injury on incidence of DVT.
