We used ultrasound to evaluate iliopsoas bursitis (IB) prevalence in 860 patients (568 males, 292 females, 62 ± 7 years) suffering from symptomatic Kellgren-Lawrence grade II-III-IV hip osteoarthritis. Lequesne index and visual analogue scale (VAS) were recorded. Anterior hip was scanned and images recorded. Maximum IB diameter was measured and drained (volume recorded). Two radiologists evaluated the presence of IB, joint effusion, synovial hypertrophy, communication between bursa and articular space. IB was found in 19/860 (2.2%) patients (16 males, 3 females, 65 ± 11 years; grade II osteoarthritis = 4; III = 9; IV = 6). Mean bursa diameter = 2.9 ± 0.9 cm, volume = 35 ± 34 mL. Effusion was present in 9/19 patients, hypertrophy in 6/19 and communication in 9/19. In patients with no IB, effusion was detected in 27/860 and hypertrophy in 25/860 (p < 0.001 compared with IB patients). κ = 1 for all. VAS index and Lequesne index were not significantly different between patients with or without IB (p ≥ 0.468). Ultrasound can detect associate findings in grade II-IV hip osteoarthritis patients with high reproducibility.
我们使用超声评估了 860 例（568 名男性，292 名女性，62 ± 7 岁）患有症状性 Kellgren-Lawrence 分级 II-III-IV 髋关节骨关节炎的患者的髂腰肌滑囊炎（IB）患病率。记录了 Lequesne 指数和视觉模拟量表（VAS）。对髋关节前侧进行扫描并记录图像。测量并排出最大 IB 直径（记录体积）。两位放射科医生评估了 IB、关节积液、滑膜肥厚、滑囊与关节间隙之间的连通情况。在 19/860（2.2%）例患者（16 名男性，3 名女性，65 ± 11 岁；II 级骨关节炎=4 例；III 级=9 例；IV 级=6 例）中发现了 IB。平均滑囊直径=2.9 ± 0.9cm，体积=35 ± 34ml。9/19 例患者存在积液，6/19 例患者存在肥厚，9/19 例患者存在连通。在无 IB 的患者中，27/860 例存在积液，25/860 例存在肥厚（与 IB 患者相比，p < 0.001）。所有情况的κ 值均为 1。有或无 IB 的患者的 VAS 指数和 Lequesne 指数无显著差异（p ≥ 0.468）。超声能够以较高的可重复性检测 II-IV 级髋关节骨关节炎患者的伴发发现。
