Abstract:
This study characterized the geometry and mechanical properties of the cervical ligaments from C2–T1 levels. The lengths and cross-sectional areas of the anterior longitudinal ligament, posterior longitudinal ligament, joint capsules, ligamentum flavum, and interspinous ligament were determined from eight human cadavers using cryomicrotomy images. The geometry was defined based on spinal anatomy and its potential use in complex mathematical models. The biomechanical force-deflection, stiffness, energy, stress, and strain data were obtained from 25 cadavers using in situ axial tensile tests. Da

Authors present their experience with 36 cases of spinal canal stenosis due to ossification of posterior longitudinal ligament in cervical spine. Ligament ossification extent was found to be local (1 segment) or segmental (2-3 segments). Clinical examination showed cervical myelopathy of various severity. Diagnosis of cervical spinal canal stenosis was determined mainly by CT and MRT. All patients underwent surgical treatment - anterior transcorporal decompression of spinal cord. Positive results were achieved in 34 patients including 22 patients with complete elimination of myelopathy, 9 pati

Abstract:
The cervical spine ligaments, including the anterior longitudinal ligament (ALL) and posterior longitudinal ligament (PLL), play a key role in maintaining spinal stability by limiting excessive movements. This study investigates how ageing affects the mechanical properties of these ligaments. We analysed 33 samples from 12 human cervical spines (15 ALL, 18 PLL), averaging data from the same donors for independent analysis, resulting in 18 final samples (8 ALL, 10 PLL). To explore age-related changes, we classified the samples into two groups—below and above 50 years old—aligning with the peak

This serves as a common language and platform to standardize clinical and radiographic outcomes for the utilization of ACR.METHODSThe proposed classification is based on 6 anatomical grades of

Abstract:
The cervical spine is a complex anatomical structure that mainly stabilizes the head and protects the spinal cord. Injuries of the cervical spine often occur during falls or road accidents and are particularly serious since they generate strong threats of paralysis and death. It should be noted that the ligaments provide cervical stability but their stabilization in case of injury is not yet well investigated. In this context, the objective of the present work is to study the failure of the ligaments by developing a bio-faithful numerical model while using a more realistic geometry of the spin

ABSTRACT Multi-level cervical spondylosis and ossification of the posterior longitudinal ligament (OPLL) are well-documented causes of myelopathy. The choice of surgical procedures remain controversial. Between January 1983 and December 1987, we have performed anterior cervical vertebrectomy in 45 patients with cervical myelopathy caused by multi-level spondylosis and OPLL. They consisted of 19 patients with cervical spondylosis, 12 with OPLL, and 14 with combined lesions of both cervical spondylosis and OPLL. There were 32 men and 13 women. The mean age was 55 years, ranging from 35 to 70 yea

Ossification of the posterior longitudinal ligament (OPLL) may occur in patients presenting with cervical myelopathy or cervical radiculopathy. Mild trauma may aggravate symptoms, resulting in a rapid progression of cervical myelopathy. Recognition is key and utilization of computed tomography is the preferred imaging modality for diagnosing OPLL. Timing of surgery is dependent on severity and progression of symptoms. Anterior and posterior approaches are acceptable, but generally the posterior approach is preferred. The use of intraoperative neuromonitoring may assist the surgeon in taking co

Segmental kinematics and ligament strains were investigated during cervical S-curvature and throughout the whiplash event. Anterior longitudinal ligament strains during S-curvature varied from 20 to 47% of maximum strains. Facet joint strains during S-curvature were 42 to 100% of max
