The purpose of this study is to evaluate the role of sonography in diagnosing lipohemarthrosis. Sonography was performed on seven patients with intra-articular fractures of the knee, shoulder, and hip. An in vitro mixture of fat and blood was examined as the gold standard. In the patients scanned a few minutes after immobilization, a two-band appearance of joint effusion was present, representing a fat-blood level. One patient scanned 3 hours after immobilization showed a three-band appearance of joint effusion, corresponding to the layers of fat, serum and red blood cells. Results of this study indicate a high reliability of ultrasonography in detecting lipohemarthrosis.
本研究的目的是评估超声检查在诊断脂肪血关节腔积血中的作用。对7例膝关节、肩关节和髋关节关节内骨折患者进行了超声检查。将脂肪和血液的体外混合物作为金标准进行检测。在固定后几分钟接受扫描的患者中，出现了关节积液的双带外观，代表脂肪-血液平面。1例在固定后3小时接受扫描的患者，关节积液呈现三带外观，分别对应脂肪、血清和红细胞层。本研究结果表明超声检查在检测脂肪血关节腔积血方面具有较高的可靠性。
