To develop age- and gender-related arthrosonographic reference intervals for the hip joint of healthy children and adolescents.
In a cross-sectional US study, we examined both hip joints of 445 children and adolescents with an age range of 1 year to 18 years. We measured the distance between the bone surface and the outer margin of the joint capsule to define the bone-capsule distance, the joint capsule and cartilage thickness, and the capsule layer thickness. Reference values were calculated. The shape of the joint capsule and bone-capsule junction zone were analyzed qualitatively. An intraobserver analysis was performed.
Bone-capsule distance, capsule thickness and the anterior capsule layer increase with age. In contrast, joint cartilage decreases. The posterior capsule layer exhibited constant thickness across all age groups. The difference between both body sides and gender was collectively less than 0.5 mm. The intraobserver variations were within the calculated reference intervals. The insertion of the capsule to the bone was mostly a peaked one. The capsule shape had a convex or straight configuration in a neutral position and a concave position during outward rotation. The intraobserver analysis revealed good to very good concordance.
We propose age- and gender-related reference intervals for the bone-capsule distance, joint capsule and cartilage thickness of the hip.
肌肉骨骼超声是一种用于诊断和监测炎性风湿性疾病的非侵入性成像方法。
为健康儿童和青少年的髋关节制定与年龄和性别相关的关节超声参考区间。
在一项横断面超声研究中，我们检查了445名年龄在1岁至18岁之间的儿童和青少年的双侧髋关节。我们测量了骨表面与关节囊外缘之间的距离以确定骨-囊距离、关节囊和软骨厚度以及囊层厚度。计算参考值。对关节囊的形状和骨-囊交界区进行定性分析。进行了观察者内分析。
骨-囊距离、囊厚度和前囊层厚度随年龄增加。相比之下，关节软骨减少。后囊层在所有年龄组中厚度保持恒定。双侧身体和性别的差异总体小于0.5毫米。观察者内变异在计算出的参考区间内。囊与骨的附着大多呈尖峰状。在中立位时，关节囊形状呈凸形或直线形，在外旋时呈凹形。观察者内分析显示一致性良好至非常好。
我们提出了与年龄和性别相关的髋关节骨-囊距离、关节囊和软骨厚度的参考区间。
