A haemodialysis patient (end-stage renal failure) with a femoral fracture and no bleeding risk should get pharmacological prophylaxis. Unfractionated heparin needs no renal dose adjustment.

• Enoxaparin (LMWH) is renally cleared and contraindicated when CrCl <15 mL/min.
• Mechanical methods (stockings, pneumatic compression) are chosen when bleeding risk is high, which is not the case here.
