Arms Assigned Interventions
Active Comparator: dalteparin 5000IU s.c.
5000IU dalteparin s.c. injected the evening before cemented total hip arthroplasty
Drug: dalteparin 5000 IU s.c.
All patients receive injections with either 5000IU dalteparin or saline in the same volume the evening before surgery. All patients receive 5000IU dalteparin 6 hours after surgery and every day from day 2 until day 35.
Other Name: Fragmin
Placebo Comparator: saline
Syringes of Saline with the same volume as in the dalteparin injections are injected the evenings before total hip arthroplasty. Dalteparin 5000IU are injected 6 hours after surgery and the concomitant 33 days
Drug: dalteparin 5000 IU s.c.
All patients receive injections with either 5000IU dalteparin or saline in the same volume the evening before surgery. All patients receive 5000IU dalteparin 6 hours after surgery and every day from day 2 until day 35.
