军事训练致膝关节滑膜炎的高频超声诊断

Value of high-frequency ultrasonography in diagnosis of gonarthromenigitis caused by army training

目的评价高频超声对创伤性膝关节滑膜炎诊断及观察疗效的价值。方法回顾性分析42例创伤性膝关节滑膜炎患者的临床资料,分析其高频超声(超声组)声像图表现,并将患者滑膜厚度、关节积液测量值与X线平片(X线组)及磁共振(MRI组)做比较。结果创伤性滑膜炎急性期滑膜厚度、关节腔积液的数值,超声组为(4.1±1.4)mm、(15.8±3.7)mm,X线组为(1.9±0.5)mm、(9.4±2.0)mm,MRI组为(4.2±1.2)mm、(16.2±4.1)mm。超声组与X线组比较均有统计学差异(P<0.05),与MRI组比较均无统计学差异。治疗前后滑膜厚度、关节腔积液及滑膜内血流信号高频超声测值比较有统计学差异(P<0.05)。结论高频超声在诊断创伤性膝关节滑膜炎、判断病情和随访中有较高的应用价值。

Objective To study the diagnosis value of high-frequency uhrasonography in the gonarthromenigitis caused by ar- my training. Methods A total of 42 patients with gonarthromenigitis caused by army training were collected to retrospective analysis. The ultrasonographic characteristics of gonarthromenigitis were analyzed and compared with those of X-rays and knee magnetic resonance imaging （MRI）. Results In ultrasound group, X-rays group, MRI group of acute traumatic synovitis, the synovial membrane thickness, articular cavity effusion quantity were （4.1 ± 1.4） mm, （ 15.8 ±3.7 ） mm ; （ 1.9 ±0.5 ） mm, （9.4 ± 2.0 ） mm ; （4.2 ± 1.2） mm, （ 16.2 ±4.1 ） ram, respectively. The difference of detection rates between ultrasound group and X-rays group was significant （ P 〈 0.05 ）, yet the difference between ultrasound group and MRI group was not significant. Before and after treatment those of high frequency ultrasound in synovial measurements were statistically significant （ P 〈 0.05 ）. Conclusions High frequency ultrasound in the diagnosis of traumatic synovitis, judging condition and follow-up has high application value.
