Patients were followed-up from 13 to 76 months (mean: 44.5 months) and assessed using the Harris Hip Score-HHS, the Hip Disability and Osteoarthritis Outcome Score-HOOS and radiographs. <strong>Results:</strong> All stems were radiologically stable. Mean Harris Hip Score was 89.8 and the HOOS was 80.4. No statistical differences were observed among patients with different diagnoses. <strong>Conclusions:</strong> The short-term results revealed satisfactory clinical outcomes and radiological signs of implant stability in all cases. Using two functional scores was useful in detecting biases and a low to moderate agreement was found between the scores.展开更多

Method: A longitudinal retrospective clinical study of a cohort of 341 individuals undergoing total hip arthroplasty between March 2008 and July 2016. Of these, 242 patients met the criteria for inclusion in the study. Individuals with a history of deep vein thrombosis or pulmonary thromboembolism, thrombophilia, hypercoagulation conditions, and chronic users of anticoagulants before surgery received enoxaparin at a dose of 40 mg/day for 21 days. For the other group, acetylsalicylic acid was prescribed at a dose of 200 mg/day for 30 days. All patients had surgical risk assessed by the American Anesthesiology Association classified as I or II, and underwent regional anesthesia, effective hydration, the same protocol of early postoperative rehabilitation, and the use of compression stockings. Drug cost analysis was performed based on the Brasíndice. To date, there are no publications in PubMed and Scielo on this subject regarding the Brazilian population. Results: The need for blood transfusion in the enoxaparin group was higher and the overall complication and hemorrhagic rates were also significantly higher (p < 0.010) in this group. Aspirin prescription costs 39 times less than enoxaparin. Conclusion: In patients without predisposing factors to thromboembolism and undergoing primary total hip arthroplasty, the multimodal approach with acetylsalicylic acid seems to be effective, with low cost and a low rate of complications.展开更多
