In this report the author describes an alternative technique of atlantoaxial fixation that involves blocking or "jamming" of movements of the atlantoaxial joint. The technique involves forcible impaction of spiked titanium metal spacers and bone grafts within the distracted atlantoaxial facet joints. Between January 2003 and January 2006, four patients underwent this method of fixation at the Department of Neurosurgery at King Edward Memorial Hospital in Mumbai, India. All four patients had posttraumatic mobile and reducible atlantoaxial dislocation. The mean follow-up period was 16 months (range 5-35 months). Successful atlantoaxial stabilization along with ultimate bone fusion was achieved in all patients and was documented on dynamic radiographs. There were no neurological, vascular, or infection-associated complications. The author concludes that the described method of atlantoaxial fixation provides an alternative treatment strategy. "Joint jamming" as a stand-alone method or in combination with other fixation methods may provide firm stabilization in cases of atlantoaxial dislocation.
在本报告中，作者描述了一种寰枢椎固定的替代技术，该技术涉及阻止或“卡住”寰枢椎关节的活动。该技术包括将带尖刺的钛金属间隔物和骨移植块强行嵌入牵张后的寰枢椎小关节内。2003年1月至2006年1月期间，印度孟买爱德华国王纪念医院神经外科有4例患者接受了这种固定方法。所有4例患者均有创伤后可活动且可复位的寰枢椎脱位。平均随访期为16个月（范围5 - 35个月）。所有患者均成功实现了寰枢椎稳定并最终达到了骨融合，动态X线片证实了这一点。没有出现神经、血管或感染相关并发症。作者得出结论，所描述的寰枢椎固定方法提供了一种替代治疗策略。“关节卡住”作为一种独立方法或与其他固定方法联合使用，在寰枢椎脱位病例中可能提供牢固的稳定效果。
