摘要
目的探讨儿童膝关节局灶性骺板区水肿的磁共振成像(MRI)影像特点,旨在为临床治疗儿童膝关节局灶性骺板区水肿提供相应的影像依据。方法选择2014年3月至2016年8月该院收治36例膝关节疼痛的儿童为研究对象,按照患者有无外伤的临床特征将患者分为无外伤组和外伤组;两组患者均行X线平片和MRI检查;比较两组患者的MRI影像特点并将其影像学表现与手术或随访结果进行对照分析,并由双盲法分析确认。结果无外伤组患者局灶性骺板区水肿的MRI特点为以骺板为中心波及邻近骨骺和干骺端的局灶性斑片状范围较小的T1WI低信号、PD-FS高信号区,边界清晰;外伤后膝关节疼痛患者骨骺板区水肿的MRI特点为骨骺板周围关节面下范围较大的T1WI低信号、PD-FS高信号区,边界不清晰。无外伤组骺板区水肿范围为(14.3±6.7)mm,外伤组骺板区水肿范围为(26.3±8.9)mm,无外伤组小于外伤组,差异有统计学意义(P<0.05)。结论儿童非外伤膝关节局灶性骺板区水肿的边界较清晰,水肿范围较小,可能与自身的生长期疼痛相关;外伤膝关节局灶性骺板区水肿的边界不清晰,水肿范围较大,可能与患者的关节损伤有关。
Objective To explore the epiphyseal plate MRI imaging features of edema of knee joint focal area in children,so as to provide the basis for the treatment of knee joint focal edema area of epiphyseal plate.Methods A total of 36 children with knee joint pain as the research subjects were selected from March 2014 to August 2016,and according to the clinical features,whether the children had trauma,they were divided into non trauma group and trauma group.And all patients in two groups were examined by radiography and MRI.MRI imaging features were compared between two groups,and performance with operation or follow-up results of the imaging were analyzed and confirmed by double blind method analysis.Results T1 WI was low signal in children with no traumatic knee joint pain of underage crowd edema,and PD-FS was high signal region as the center to the epiphyseal plate affecting adjacent epiphyseal and metaphyseal focal patchy smaller clear boundary.MRI features of children with minor trauma knee edema joint pain with epiphyseal plate area around the articular surface under the scope of T1 WI showed low signal,PD-FS was high signal area,the boundary was not clear.Range of children in non-traumatic group edema was（14.3±6.7）mm,which of trauma group edema range was（26.3±8.9）mm,differences were statistically significance（P〈0.05）.Conclusion Edema boundary focal area of non-traumatic knee joint the epiphyseal plate is clear,edema range has small scope,which may be associated with the growth period of traumatic knee joint pain.And the focal edema of the epiphyseal plate of children with trauma boundary is not clear,edema range is larger,which may be associated with joint damage.
