In 7 of 8 patients with non-acute slipped capital femoral epiphysis, the slip was visualized by ultrasound. The mean epiphyseal displacement was 6.0 mm, measured on an anterior ultrasound scan. Grading of slip severity by ultrasound was consistent with the radiographic assessment. Two patients had a moderate hip joint effusion which did not affect the final outcome, whereas one patient with an acute slip had a pronounced effusion, and necrosis of the epiphysis occurred. The anteversion angles of the affected hips were reduced as compared to those of the normal hips. It was concluded that ultrasonography was reliable in detecting pronounced and mild degrees of epiphyseal slips, whereas minimal slips could be missed. The detection of hip effusion is important because a tamponade may cause vascular impairment of the epiphysis, unless aspirated.
在8例非急性股骨头骨骺滑脱患者中，有7例通过超声可观察到滑脱情况。在前位超声扫描上测得的平均骨骺移位为6.0毫米。超声对滑脱严重程度的分级与X线评估结果一致。2例患者有中度髋关节积液，但未影响最终结局，而1例急性滑脱患者有明显积液，并发生了骨骺坏死。与正常髋关节相比，患侧髋关节的前倾角度减小。结论是，超声在检测明显和轻度骨骺滑脱方面是可靠的，而微小滑脱可能会漏诊。髋关节积液的检测很重要，因为除非进行抽吸，否则填塞可能会导致骨骺的血管受损。
