DVT Prophylaxis in Orthopaedics

Risk high in hip/knee arthroplasty, hip fracture surgery, pelvic/acetabular trauma, prolonged immobility. Options: LMWH, DOACs (apixaban/rivaroxaban), aspirin (selected low‑risk arthroplasty), mechanical methods (IPC/stockings). Duration: 10–14 days minimum; up to 35 days after hip fracture/arthroplasty. Balance bleeding risk (neuraxial anesthesia timing) with VTE prevention.
