The author has described his own technique of DCER (distraction, compression, extension, and reduction) to reduce and realign the deformity and relieve spinal compression (indicated in congenital anomalies with occipitalized C1 arch). In addition, he developed special C1-2 spacers and a universal reducer. Here, a 30-year-old male with severe BI (20 mm, above the clivus) with AAD underwent the technique of spacer placement (distraction) followed by cable reduction (leading to compression and extension at the occiput-C1-C2 region). Another short example is presented where an 8-year-old boy (severe BI, AAD with posterior fossa dermoid) underwent additional correction-C2 forward translation and excision of the dermoid.

作者描述了自己的DCER（撑开、加压、伸展和复位）技术，以矫正畸形并使其重新对齐，缓解脊柱压迫（适用于枕化C1椎弓的先天性异常）。此外，他还研发了特殊的C1-2间隔器和通用复位器。在此，一名30岁男性，患有严重的基底凹陷（20毫米，斜坡上方）并伴有寰枢椎脱位，接受了间隔器置入（撑开）技术，随后进行缆线复位（导致枕骨-C1-C2区域的加压和伸展）。还给出了另一个简短的例子，一名8岁男孩（严重基底凹陷，伴有后颅窝皮样囊肿的寰枢椎脱位）接受了额外的矫正——C2向前移位和皮样囊肿切除。视频可在此处查看：https://youtu.be/XIMpkYjxgRk 。
