Sonographic evaluation of lipohemarthrosis: clinical and in vitro study
S. Bianchi, A. Zwass, I. F. Abdelwahab, G. Ricci, F. Rettagliata and M. Olivieri
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. This article has been cited by other articles:
