背景:寰枢关节作为连接头颅和脊柱的节点,在维持头颈部的运动、保持脑部和脊髓的联系上有着重要的作用.寰枢关节的生物力学特性与外部损伤性因素共同决定了寰枢关节骨折、脱位的部位、类型和性质,也影响着寰枢关节损伤后的治疗方法.随着材料技术的进展和临床操作经验的积累,各种新型的置入物不断被研制并应用于临床实践,使寰枢椎的手术方式和治疗策略得到了极大的丰富.目前置入物的应用目的大都是促进寰枢椎的融合或加强寰枢椎之间的联系和固定,它们在加强寰枢关节稳定性的同时,都不同程度地限制了头颈部的活动.如何处理好稳定性和灵活性的关系,在保证寰枢关节稳定的基础之上最大限度地恢复其生理功能,是今后新型人工置入物的研究方向.

As a node between the skull and the spine, atlantoaxial joint plays a pivotal role in the maintenance of head and neck activities, as well as the connection between the brains and the spine. The biomechanical characteristics of stlantoaxial joint, together with traumatic factors, contribute to determine the site, type and character of atlantoaxial joint fracture and dislocation, they also affect the treatment of atlantoaxial joint injury. With the materials technique development and accumulated experience of clinical operations, various types of new implants are increasing and used for clinical practice, accordingly the surgical approach and therapy regimen of atlantoaxial disease have been greatly enriched. At present, the use of implant mainly aims to promote the atlantoaxial fusion or enhance the connection and fixation between atlantoaxial joints. However, the head and neck activities are also limited simultaneously while the implant enhances the atlantoaxial joint stability. Further studies require to handle the correlation between joint stability and joint flexibility and to maximize the physiological function recovery of atlantoaxial joints when ensuring the atlantoaxial joint stability.
