摘要
目的探讨并分析后踝撞击综合征(PAIS)MRI影像特征的相关因素。方法回顾性分析2016年4月—2017年5月临床疑诊PAIS病人117例,其中男62例,女55例,年龄17～72岁,平均(40.4±12.2)岁,均行MRI检查。采用Logistic回归分析评估副三角骨、副三角骨骨髓水肿、副三角骨囊变或/和硬化、距骨后突过长、距骨后突骨髓水肿、距骨后突囊变或/和硬化、后踝滑膜炎、后踝关节腔积液、距骨后缘骨髓水肿、踇长屈肌腱鞘积液及后踝软组织肿胀共11个影像征象与PAIS诊断相关的影响因素。结果 117例病人中41例(35.0%)经临床确诊为PAIS,其中副三角骨24例,副三角骨骨髓水肿13例,副三角骨囊变或/和硬化3例,距骨后突过长17例,距骨后突骨髓水肿7例,距骨后突囊变或/和硬化1例,后踝滑膜炎38例,后踝关节腔积液40例,距骨后缘骨髓水肿12例,踇长屈肌腱鞘积液14例,后踝软组织肿胀10例。单因素Logistic回归分析显示,副三角骨、副三角骨骨髓水肿的差异均具有统计学意义(均P<0.05);多因素Logistic回归分析显示,副三角骨骨髓水肿的差异具有统计学意义[优势比(OR)为0.302(95%CI:0.108～0.839),P=0.022]。结论副三角骨骨髓水肿是PAIS诊断的影响因素,副三角骨出现骨髓水肿可高度提示病人患有PAIS。
Objective To investigate relevant MRI imaging features for posterior ankle impingement syndrome(PAIS).Methods This retrospective study was conducted in 117 patients with clinically suspected PAIS on MRI examinations between April 2016 and May 2017,including 62 males and 55 females,age 17~72 years,average age 40.4±12.2 years.Logistic regression was used to evaluate the influence factors in the diagnosis of PAIS,including os trigonum,os trigonum marrow edema,os trigonum cystic change or/and hardening,stieda’s process long,stieda’s process marrow edema,stieda’s process cystic change or/and hardening,posterior ankle synovial inflammation,posterior ankle effusion,talus edge marrow edema,flexor hallucis longus tendon effusion,posterior ankle soft tissue swelling of 11 image signs.Results Forty one(35.0%)of 117 patients were clinically diagnosed with PAIS,including os trigonum in 24 cases,os trigonum marrow edema in 13 cases,os trigonum cystic change or/and hardening in 3 cases,stieda’s process long in 17 cases,stieda’s process marrow edema in 7 cases,stieda’s process cystic change or/and hardening in 1 cases,posterior ankle synovial inflammation in 38 cases,posterior ankle effusion in 40 cases,talus edge marrow edema in 12 cases,flexor hallucis longus tendon effusion in 14 cases,posterior ankle soft tissue swelling in 10 cases.Single factor logistic regression analysis showed the differences in edema at os trigonum and os trigonum marrow were statistically significance(P<0.05).Multivariate logistic regression analysis showed the difference in edema at os trigonum marrow was statistically significance[OR 0.302(95%CI:0.108~0.839),P=0.022].Conclusion Os trigonum marrow edema is an influential factor in the diagnosis of PAIS,os trigonum marrow edema highly suggests the patient has PAIS.
