目的探讨椎体成形术后相邻椎体骨折的发生原因和治疗方法。方法对2002年12月至2009年2月椎体成形术后568例相邻椎体发生再次骨折24例，询问病史并查体，重视首次治疗资料的保管，认真与原有资料对比，常规应用MRI和CT检查进行诊断，并对发生原因进行分析，实施椎体成形术进行治疗。结果本组病例相邻椎体骨折发生率为4．23％，全部发生在手术后1年内。发生原因主要与骨质疏松的程度、穿刺注射方法和不规范手术后管理有关。常规做MRI和CT检查，可以提高相邻椎体骨折的诊断率。再次椎体成形术疼痛缓解满意，完全缓解19例，部分缓解5例。结论椎体成形术后可以发生相邻椎体的骨折，改进穿刺注射方法，加强手术后管理，正规康复训练和规范的全身抗骨质疏松药物治疗可以降低发生率。

Meningeal lymphatic vessels form a relationship between the nervous system and periphery, which is relevant in both health and disease. Meningeal lymphatic vessels not only play a key role in the drainage of brain metabolites but also contribute to antigen delivery and immune cell activation. The advent of novel genomic technologies has enabled rapid progress in the characterization of myeloid and lymphoid cells and their interactions with meningeal lymphatic vessels within the central nervous system. In this review, we provide an overview of the multifaceted roles of meningeal lymphatic vessels within the context of the central nervous system immune network, highlighting recent discoveries on the immunological niche provided by meningeal lymphatic vessels. Furthermore, we delve into the mechanisms of crosstalk between meningeal lymphatic vessels and immune cells in the central nervous system under both homeostatic conditions and neurodegenerative diseases, discussing how these interactions shape the pathological outcomes. Regulation of meningeal lymphatic vessel function and structure can influence lymphatic drainage, cerebrospinal fluid-borne immune modulators, and immune cell populations in aging and neurodegenerative disorders, thereby playing a key role in shaping meningeal and brain parenchyma immunity.
