Median nerve entrapment is a rare complication of posterior elbow dislocation and medial epicondyle fracture. In the event of delayed diagnosis, this injury pattern may result in significant and sometimes irreversible nerve damage. As such, a high degree of clinical suspicion and early imaging is indicated in patients with persistent nerve deficits following reduction of elbow dislocation. Here, a case of intraosseous type 2 median nerve entrapment that was diagnosed on ultrasound in an eight-year-old patient following ulnohumeral dislocation is discussed. This article reviews the key imaging findings of median nerve entrapment and discusses the subsequent MRI and surgical findings of this rare condition.
正中神经卡压是肘后脱位和内上髁骨折的一种罕见并发症。如果诊断延迟，这种损伤模式可能会导致严重的、有时甚至是不可逆的神经损伤。因此，对于肘关节脱位复位后仍存在神经功能缺损的患者，需要高度的临床怀疑并进行早期影像学检查。本文讨论了一例8岁尺肱关节脱位患者经超声诊断为骨内型2型正中神经卡压的病例。本文回顾了正中神经卡压的关键影像学表现，并讨论了这种罕见疾病随后的MRI和手术所见。
