One hundred non-operated hip joints in 50 adult patients with active rheumatoid polyarthritis were examined by ultrasonography as well as by clinical methods and X-ray. In 15 hip joints in 11 patients, ultrasonography indicated intra-articular effusion (a distance between the joint capsule and bone of more than 7 mm in 14 and a difference between the two sides of more than 1.5 mm for one hip). There were no subjective symptoms associated with five of these hip joints, the X-ray findings were normal for 11 hips, and careful clinical examination showed normal findings for one hip joint. The routine clinical examination used in the hospital had revealed pathological findings in only two of these hip joints. It is concluded that ultrasonography may reveal intra-articular effusion or synovitis in clinically and radiologically apparently normal hip joints of patients with active rheumatoid arthritis. The increase in pain and restricted motion was statistically significant in the hips for which ultrasonography indicated intra-articular effusion. Hips that appear pathological in ultrasonography are thus synovitis, and do not fall within the range of normal variation for healthy hip joints.
对50例患有活动性类风湿性多关节炎的成年患者的100个未接受手术的髋关节进行了超声检查以及临床检查和X线检查。在11例患者的15个髋关节中，超声检查显示关节内积液（14个髋关节的关节囊与骨骼之间的距离超过7毫米，1个髋关节两侧的差异超过1.5毫米）。其中5个髋关节没有相关的主观症状，11个髋关节的X线检查结果正常，仔细的临床检查显示1个髋关节检查结果正常。医院使用的常规临床检查仅在其中2个髋关节中发现了病理结果。结论是，超声检查可能会在患有活动性类风湿性关节炎患者的临床和放射学上看似正常的髋关节中发现关节内积液或滑膜炎。超声检查显示关节内积液的髋关节中，疼痛增加和活动受限在统计学上具有显著意义。因此，超声检查显示为病理性的髋关节存在滑膜炎，不属于健康髋关节的正常变异范围。
