高频超声在类风湿手部小关节炎滑膜病变程度判断中的价值研究

目的 探讨高频超声在类风湿手部小关节炎滑膜病变程度判断中的价值.方法 选择类风湿关节炎患者36例作为观察组,健康志愿者38例作为对照组,采用高频超声观察研究对象双手掌指及关节近端指间关节,比较各手指关节滑膜的厚度.结果 观察组中25 （69.4％）例可见关节滑膜增厚,5例可见关节腔积液,3例可见骨质破坏,2例可见关节融合.除左手第1掌指、左手第2指间、左手第4掌指和左手第5指间外,两组的手指关节滑膜厚度比较,差异有统计学意义（P＜0.05）.结论 高频超声在类风湿手部小关节炎滑膜病变程度判断中具有较高的应用价值.

Value research of high-frequency ultrasound in the judgment of synovial lesion degree with small rheumatoid arthritis of hand

Objective To explore the value of high-frequency ultrasound in the judgment of synovial lesion degree with small rheumatoid arthritis of hand.Methods 36 cases of patients with rheumatoid arthritis were selected as observation group,38 healthy volunteers were selected as control group.Metaearpophalangeal and proximal interphalangeal joint of patient hand with high-frequency ultrasound were observed,each finger joint synovial thickness was compared respec- tively.Results 25 cases showed synovial thickness in observation group,accounted for 69.4%,5 patients showed articular cavity effusion,3 patients showed bone destruction,2 patients showed joint fusion.In addition to first metacarpopha- langeal,second finger,fourth metacarpophalangeal and fifth finger of left hand,finger joint synovial thickness in two groups was compared respectively,with statistical difference （P〈0.05）.Conclusion High-frequency ultrasound has high application value in the judgment of synovial lesion degree with small rheumatoid arthritis of hand.
