Abstract

Posterior ligamentous complex (PLC) serves as a crucial structural support of the human spine, consisting of the supraspinous ligament (SSL), interspinous ligament (ISL), and ligamentum flavum (LF), with each of these ligaments contributing greatly to limit biomechanical stress. While there is a general agreement on these key components, the literature still varies regarding the inclusion of the intertransverse ligament (ITL) and facet joint (FJ) capsules. Together, these ligaments contribute 30-40% of spinal stability. Preserving the structural and functional integrity of the PLC is essential in surgical planning, as ligaments that are compromised can affect postoperative spinal alignment and load distribution. While it has been revealed that each ligament has unique biomechanical properties, their collective function is essential for distributing mechanical loads and protecting adjacent structures. In this narrative review we offer an in-depth synthesis of the current available literature and offer an essential foundation for clinicians and researchers who aim to study the PLC biomechanical and anatomical function.

人类脊柱后韧带复合体的解剖学和生物力学：叙述回顾。

后韧带复合体（PLC）是人体脊柱的重要结构支撑，由棘上韧带（SSL）、棘间韧带（ISL）和黄韧带（LF）组成，这些韧带中的每一条都对限制生物力学应力有很大贡献。虽然对这些关键组成部分有普遍的共识，但关于横间韧带（ITL）和小关节（FJ）囊的纳入，文献仍然存在差异。这些韧带共同贡献了30-40%的脊柱稳定性。保留PLC的结构和功能完整性在手术计划中至关重要，因为受损的韧带会影响术后脊柱对齐和负荷分布。虽然已经发现每个韧带都具有独特的生物力学特性，但它们的集体功能对于分配机械负荷和保护邻近结构至关重要。在这篇叙述性综述中，我们提供了当前可用文献的深入综合，并为旨在研究PLC生物力学和解剖功能的临床医生和研究人员提供了必要的基础。

期刊介绍： Anatomy is a morphological science which cannot fail to interest the clinician. The practical application of anatomical research to clinical problems necessitates special adaptation and selectivity in choosing from numerous international works. Although there is a tendency to believe that meaningful advances in anatomy are unlikely, constant revision is necessary. Surgical and Radiologic Anatomy, the first international journal of Clinical anatomy has been created in this spirit. Its goal is to serve clinicians, regardless of speciality-physicians, surgeons, radiologists or other specialists-as an indispensable aid with which they can improve their knowledge of anatomy. Each issue includes: Original papers, review articles, articles on the anatomical bases of medical, surgical and radiological techniques, articles of normal radiologic anatomy, brief reviews of anatomical publications of clinical interest. Particular attention is given to high quality illustrations, which are indispensable for a better understanding of anatomical problems. Surgical and Radiologic Anatomy is a journal written by anatomists for clinicians with a special interest in anatomy.
