The ligamenta flava may also become fatty or calcify during ageing. [2] These cause degeneration of elastin. [2] Some studies indicate that the hypertrophy of these ligaments may be linked to a fibrotic process associated with increased collagen VI, which could represent an adaptive and reparative process in response to the rupture of elastic ...
The posterior atlantoaxial ligament is a broad, thin membrane attached, above, to the lower border of the posterior arch of the atlas; below, to the upper edges of the laminæ of the axis. It supplies the place of the ligamenta flava , and is in relation, behind, with the obliqui capitis inferiores .
Lesions to the supraspinous ligament may result in palpable thickening. [5] Ultrasound is effective for detecting lesions. [5] [6] A strain injury can also damage the supraspinous ligament. [7] The supraspinous ligament creates resistance during midline epidural anaesthetics when the needle is being inserted.
The tectorial membrane of atlanto-axial joint (occipitoaxial ligaments) is a tough membrane/ [1] broad, strong band [2] representing the superior-ward prolongation of the posterior longitudinal ligament (the two being continuous). [3] [1] [2] It attaches inferiorly onto (the posterior aspect of [2]) the body of axis. [3] It broadens superiorly.
They meet the ligamenta flava anteriorly, [4] [better source needed] and blend with the supraspinous ligament [3] posteriorly at the apexes of the spinal processes. The function of the interspinous ligaments is to limit ventral flexion of the spine and sliding movement of the vertebrae. [5] The ligaments are narrow and elongated in the thoracic ...
The vertebral canal is enclosed anteriorly by the vertebral bodies, intervertebral discs, and the posterior longitudinal ligament; it is enclosed posteriorly by the vertebral laminae and the ligamenta flava; laterally, it is incompletely enclosed by the pedicles with the interval between two adjacent pedicles on either side creating an intervertebral foramen (allowing the passage of the spinal ...
Inferiorly, it becomes continuous with the anterior sacrococcygeal ligament. [3] Superiorly, between the skull and atlas, the ligament is continuous laterally with the anterior atlantooccipital membrane. [4] The ligament is thick and slightly more narrow over the vertebral bodies and thinner but slightly wider over the intervertebral discs. [5]
A laminotomy is an orthopaedic neurosurgical procedure that removes part of the lamina of a vertebral arch in order to relieve pressure in the vertebral canal. [1] A laminotomy is less invasive than conventional vertebral column surgery techniques, such as laminectomy because it leaves more ligaments and muscles attached to the spinous process intact and it requires removing less bone from the ...
