Physiologic anterior subluxation is a phenomenon that is common to the upper pediatric cervical spine and characterized by the normal forward displacement of one cervical vertebra relative to the subjacent one. Physiologic anterior subluxation can be seen in children in the setting of trauma, when it must be distinguished from pathologic subluxation. Physiologic anterior subluxation has not been reported at lower cervical spinal levels (C 5 to C 6 or C 6 to C 7 ). This is a report of physiologic anterior subluxation at C 5 to C 6 and C 6 to C 7 spinal levels distinguished from pathologic subluxation in a 9-year-old child evaluated in the acute setting after cervical spine injury.
生理性前半脱位是小儿上颈椎常见的一种现象，其特征为一个颈椎相对于其下方相邻颈椎的正常向前移位。在儿童创伤情况下可出现生理性前半脱位，此时必须将其与病理性半脱位相鉴别。生理性前半脱位在颈椎较低节段（C5至C6或C6至C7）尚未见报道。本文报告了一名9岁儿童在颈椎损伤急性期评估时，C5至C6和C6至C7节段生理性前半脱位与病理性半脱位的鉴别情况。
