80The purpose of this study is to determine if there are differences in clinical events, i.e bleeding with associated morbidity, if thromboprophylaxis with LMWH (Low Molecular Weight Heparin) is initiated before or after surgery.
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.
5000IU dalteparin s.c. injected the evening before cemented total hip arthroplasty
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
Inclusion Criteria: -patients 50 years or older undergoing cemented total hip arthroplasty for primary osteoarthritis Exclusion Criteria: allergy to Low-Molecular-Weight -Heparin bleeding disorders renal failure hepatic disease active treatment for malignancy history of deep venous thrombosis or pulmonary embolism major operations,trauma,stroke or cardiac infarction the last 3 months before surgery.
