The Impact of Spine Pathology on Posterior Ligamentous Complex Structure and Function.
Purpose of review: Spinal ligament is an important component of the spinal column in mitigating biomechanical stress. Particularly the posterior ligamentous complex, which is composed of the ligamentum flavum, interspinous, and supraspinous ligaments. However, research characterizing the biomechanics and role of ligament health in spinal pathology and clinical context are scarce. This article provides a comprehensive review of the implications of spinal pathology on the structure, function, and biomechanical properties of the posterior ligamentous complex.
Recent findings: Current research characterizing biomechanical properties of the posterior ligamentous complex is primarily composed of cadaveric studies and finite element modeling, and more recently incorporating patient-specific anatomy into finite element models. The ultimate goal of current research is to understand the relative contributions of these ligamentous structures in healthy and pathological spine, and whether preserving ligaments may play an important role in spinal surgical techniques. At baseline, posterior ligamentous complex structures account for 30-40% of spinal stability, which is highly dependent on the intrinsic biomechanical properties of each ligament. Biomechanics vary widely with pathology and following rigid surgical fixation techniques and are generally maladaptive. Often secondary to morphological changes in the setting of spinal pathology, but morphological changes in ligament may also serve as a primary pathology. Biomechanical maladaptations of the spinal ligament adversely influence overall spinal column integrity and ultimately predispose to increased risk for surgical failure and poor clinical outcomes. Future research is needed, particularly in living subjects, to better characterize adaptations in ligaments that can provide targets for improved treatment of spinal pathology.
期刊介绍:
This journal intends to review the most significant recent developments in the field of musculoskeletal medicine. By providing clear, insightful, balanced contributions by expert world-renowned authors, the journal aims to serve all those involved in the diagnosis, treatment, management, and prevention of musculoskeletal-related conditions.
We accomplish this aim by appointing authorities to serve as Section Editors in key subject areas, such as rehabilitation of the knee and hip, sports medicine, trauma, pediatrics, health policy, customization in arthroplasty, and rheumatology. Section Editors, in turn, select topics for which leading experts contribute comprehensive review articles that emphasize new developments and recently published papers of major importance, highlighted by annotated reference lists. We also provide commentaries from well-known figures in the field, and an Editorial Board of more than 20 diverse members suggests topics of special interest to their country/region and ensures that topics are current and include emerging research.
