To report the incidence of deep vein thrombosis (DVT) in ipsilateral femur and tibial fractures (floating knee).
This is a retrospective, analytical, observational study conducted with the medical records of thirty patients admitted to a trauma hospital between October 2016 and July 2017 with floating knee.
Patients aged between 21-30 years were the most affected by the condition (36%). Seventeen patients affected the dominant limb (57%); 19 (63%) patients were classified as Fraser type I, 18 (60%) had open (compound) fractures, 16 (53%) tibial fractures, and 8 (26%) femoral fractures. External fixation of the femur and tibia (25 patients = 83%) was the most common emergency treatment. In total, 17% of patients presented deep venous thrombosis (p = 0.409).
Despite antithrombotic prophylaxis, the incidence of DVT in the affected limb of patients with floating knee was high. We found patients with Fraser I fractures, male, and with fractures in the non-dominant limb to present a higher chance of developing DVT.
报告同侧股骨和胫骨骨折（浮动膝）患者深静脉血栓形成（DVT）的发生率。
这是一项回顾性、分析性观察研究，对2016年10月至2017年7月间入住一家创伤医院的30例浮动膝患者的病历进行分析。
21至30岁的患者受该疾病影响最为严重（36%）。17例患者累及优势肢体（57%）；19例（63%）患者被归类为弗雷泽I型，18例（60%）为开放性（复合性）骨折，16例（53%）为胫骨骨折，8例（26%）为股骨骨折。股骨和胫骨的外固定（25例患者 = 83%）是最常见的急诊治疗方法。共有17%的患者出现深静脉血栓形成（p = 0.409）。
尽管采取了抗血栓预防措施，但浮动膝患者患侧肢体深静脉血栓形成的发生率仍很高。我们发现，弗雷泽I型骨折患者、男性患者以及非优势肢体骨折患者发生深静脉血栓形成的几率更高。
