髂胫束摩擦综合症临床与MR表现特点

Clinical and MR Features of Lliotibial Bundle Friction Syndrome

目的:探讨髂胫束摩擦综合症(lliotibial band friction syndrome,ITBFS)的临床症状与MRI表现特点的相关性。方法:回顾性分析2018年6月至2019年7月我院收治的33例经临床确诊ITBFS的临床及MRI检查资料。33例患者均行临床体格检查及膝关节MRI检查,观察分析不同临床表现ITBFS患者的MRI影像学特点。结果:临床表现为膝关节外侧肿胀、疼痛,屈膝20度~30度时症状加剧;后期伸屈患侧膝关节时,可有局部摩擦感或弹响,常提示髂胫束变性;在MRI上,髂胫束轻度肿胀2例;髂胫束明显增粗、信号增高者6例;10例发生髂胫束连续改变,呈波浪状,附着处水肿;9例发生髂胫束断裂、断端短缩;6例表现为后期髂胫束损伤后纤维化、变硬。结论:ITBFS在临床和MRI表现上可有一定的特点,通过MRI可以有效地显示髂胫束形态、部位、信号改变以及周边情况,指导临床治疗并进行影像学评估。

Objective:To investigate the clinical and MRI features of iliotibial tract friction syndrome(lliotibial band friction syndrome,ITBFS).Methods:The clinical and MRI data of 33 cases of ITBFS admitted in our hospital from June 2018 to July 2019 were retrospectively analyzed.All 33 patients underwent clinical physical examination and knee MRI,and the MRI imaging features of patients with different clinical manifestations of ITBFS were observed and analyzed.Results:The symptoms of lateral swelling and pain of knee joint were increased from 20 to 30 degrees.On MRI,there were 2 cases of mild swelling of iliac tibial tract;The iliac tibial tract thickened significantly and the signal increased in 6 cases;In 10 cases,the iliac tibial tract was changed continuously,which was wavy.In 9 cases,the fracture of iliac tibia occurred and the broken end was shortened;In 6 cases,fibrosis and sclerosis were observed in the later stage of the iliac tibial tract injury.Conclusion:ITBFS can have some characteristics in clinical and MRIperformance.MRI can effectively show the form,location,signal change and peripheral condition of iliotium,guide clinical treatment andevaluate imaging.
