在尸体研究和最近在一名成人患者中，枕骨髁被研究为允许通过固定器械进行骨咬合的一种选择。在当前病例中，作者描述了枕髁螺钉在接受枕颈固定的儿童中的使用。据作者所知，这是第一次报告的情况下，这种技术在儿科患者。这个女孩有一个历史的后颅窝减压术的基亚里畸形I型时，她是22个月大。当她6岁时，她提出了颈部疼痛的弯曲和伸展她的头。屈曲和伸展的磁共振成像显示枕颈不稳定。她接受了枕骨至C-2后路关节融合术，在枕骨髁、C-2椎板和C-1侧块中放置了双侧螺钉。术后，她的神经功能完好无损。计算机断层扫描显示结构稳定，随访时颈椎疼痛已消退。(DOI：10.317/2010.4.PEDS09551）
In cadaveric studies and recently in one adult patient the occipital condyle has been studied as an option to allow bone purchase by fixation devices. In the current case the authors describe the use of occipital condyle screws in a child undergoing occipitocervical fixation. To the best of the authors' knowledge this case is the first reported instance of this technique in a pediatric patient.This girl had a history of posterior fossa decompression for Chiari malformation Type I when she was 22 months of age. When she was 6 years old she presented with neck pain on flexion and extension of her head. Magnetic resonance imaging in flexion and extension revealed occipitocervical instability. She underwent an occiput to C-2 posterior arthrodesis with bilateral screw placement in the occipital condyles, C-2 lamina, and C-1 lateral masses. Postoperatively, she was neurologically intact. Computed tomography demonstrated a stable construct, and her cervical pain had resolved on follow-up. (DOI: 10.317/2010.4.PEDS09551)
