The nonechogenic space between the bone and the joint capsule was measured in ultrasonographic scans at six different sites in 60 elbow joints of 30 healthy adults as well as in 35 joints with clinical arthritis. The space could be demonstrated in all healthy joints on the volar side at the levels of the trochlea and the capitulum of the humerus. The space was more than 2 mm in three out of the 60 healthy joints at these levels, and the space did not increase in 30 degrees flexion of the joint. The means of the measurements were significantly higher at all six sites in the arthritic joints than in the healthy joints and on the volar site the space increased in 30 degrees flexion of the arthritic joint. The space was more than 2 mm in all arthritic joints at the levels of either the trochlea or the capitulum of the humerus. An ultrasonographic distance of more than 2 mm on the volar side of the elbow joint between the joint capsule and the bone is with high probability a sign of intraarticular effusion or synovitis. The effusion in the olecranon fossa can also be demonstrated in all cases.
在30名健康成年人的60个肘关节以及35个临床关节炎关节的超声扫描中，测量了骨骼与关节囊之间的无回声间隙。该间隙在所有健康关节的掌侧，肱骨滑车和小头水平处均可显示。在这些水平上，60个健康关节中有3个关节的间隙超过2毫米，并且关节在30度屈曲时间隙没有增加。关节炎关节所有六个部位的测量平均值均显著高于健康关节，并且在掌侧，关节炎关节在30度屈曲时间隙增大。在肱骨滑车或小头水平处，所有关节炎关节的间隙均超过2毫米。肘关节掌侧关节囊与骨骼之间超声测量距离超过2毫米很可能是关节内积液或滑膜炎的迹象。所有病例中鹰嘴窝的积液也均可显示。
