ObjectivesTo compare the efficacy and safety of aspirin and rivaroxaban in preventing venous thromboembolism (VTE) after total knee arthroplasty (TKA).MethodsThirty-two patients with osteoarthritis of the knee and knee arthroplasty indication were selected. The operated patients were randomized into two groups (A and B). Group A received 300 mg of acetylsalicylic acid (aspirin) and Group B received 10 mg of rivaroxaban daily for 14 days. Follow-up was performed weekly for four weeks and evaluated the presence of signs and symptoms of DVT, the healing of the surgical wound, and possible local complications such as hematoma, and superficial or deep infection that required surgical approach.ResultsIt was verified that there were no differences between groups (rivaroxaban and aspirin) regarding gender, age, and (p > 0.05). After using the general linear model (GLM) test, it was found that there was a decrease in Hb and Ht levels, preoperatively and at one, three, seven, and 14 days (Hb: p = 1.334 × 10−30; Ht: p = 1.362 × 10−28). However, they did not differ as to the type of medication (Hb: p = 0.152; Ht: p = 0.661). There were no identifiable differences in local complications, systemic complications, deep vein thrombosis (DVT), readmission to hospital, reoperation, or death (p > 0.05) between groups (rivaroxaban and aspirin).ConclusionsBoth aspirin and rivaroxaban can be considered useful among drugs available VTE the prevention after TKA.
ObjectiveTo analyze the clinical-functional parameters and quality of life of patients undergoing minimally invasive surgical treatment for extra-articular fractures of the proximal phalanx, using an intramedullary screw (Acutrak®).MethodsBetween January 2011 and September 2014, a prospective study was conducted on 41 patients (48 fingers) with unstable extra-articular fractures of the proximal phalanx, who underwent minimally invasive surgical treatment using an intramedullary screw (Acutrak®). These patients were evaluated 12 months after the surgery by means of the DASH quality-of-life questionnaire, VAS pain scale, measurement of range of motion (ROM, in degrees) and radiographic assessment.ResultsAll the patients achieved adequate reduction and consolidation of their fractures. There were statistically significant improvements in quality of life on the DASH scale, pain on the VAS scale and range of motion.ConclusionThe minimally invasive technique for treating unstable extra-articular fractures of the proximal phalanx using an intramedullary screw (Acutrak®) is effective and safe, and it presents satisfactory clinical-functional results.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
