摘要
目的:探讨儿童肘关节不典型损伤的MR信号特征及其诊断价值。方法:分析41例临床怀疑肘关节不典型损伤在我院行MR检查的患儿的MR表现。均有伤后肘关节正侧位X线平片,其中加做CT检查3例。结果:41例中,31例(75.6%)经MR检查确诊为儿童肘关节不典型损伤。其中X线平片或CT检查未见骨折病例中,骨骺骨折7例,关节软骨骨折3例,骨挫伤18例;肌腱损伤0例。6例X线或CT检查虽可诊断骨折但不能显示损伤是否累及关节面,MR检查证实平片所见,并进一步确诊骨折并伴不典型损伤者3例。单纯骨折不伴不典型损伤者3例,仅有单纯软组织损伤或关节积液5例。结论:MRI能清晰显示儿童肘关节不典型损伤的部位、性质和程度,应作为儿童肘关节不典型损伤的首选检查方法。在儿童肘关节不典型损伤的诊断中具有重要诊断价值。
Objective：To approach the diagnostic value and characteristic appearance of MRI in atypical elbow injury in children.Methods：To analyze MRI appearance of 41 children who were suspected of having atypical elbow injury.All patients performed lateral and postero-antarior position of the elbow X-ray films and 3 cases performed CT scan.Results：In 41 cases,31（75.6%） were diagnosed as atypical children elbow injury by MR.Among patients who had no fracture on X-ray or CT examination,epiphyseal injury was found in 7 cases,3 cases had articular cartilage fracture;bone contusion in 18 cases;none had tendon injury.On the X-ray or CT image,6 cases had a clear diagnosis of fracture but can not show articular surface involvement.MR confirmed the diagnosis of X-ray or CT image,and 3 patients of them had atypical fracture.Three cases had simple fracture without atypical injury,conservative treatment was accepted by gypsum fixation;5 cases only had simple soft tissue injury or joint effusion,no treatment was needed.Four cases had two fractures at the same time.Two cases had suspicious fracture on X-ray but MR explicitly excluded bone injury and only had soft tissue swelling.Conclusion：MRI is the first choice for examination of children＇s elbow atypical injury and can clearly show the location,nature and extent of children＇s elbow atypical injury which is very helpful to the diagnosis.
