What are the functions of ligaments?
- Limit motion
- assist maintaining normal curves
- enhance stability
- proprioception - spinal ligaments contain mechanoreceptors & provide information on posture, ligament stretch
Ligamentum flavum
- found between lamina
- highly elastic: "yellow ligament"
- limits flexion protecting discs from compression
- posterior to spinal cord
- hyperextension buckle ligament and pinch spinal cord
Supraspinous ligament
- extends between adjacent spinous spinous (from the sacrum to C7)
- limits flexion
- lumbar spine: typically 1st to rupture with extreme flexion
Interspinous ligament
- extend between adjacent spinous processes (from sacrum to C7)
- limits flexion
- lumbar spine: typically 1st to rupture with extreme flexion
ligamentum nuchae
- thickening of supraspinous and interspinous in c-spine
- support to head and neck (passive tension)
- accounts for difficulty palpating spinous process in mid to upper cervical region
intertransverse
- adjacent transverse processes
- limits contralateral lateral flexion
anterior longitudinal ligament
- anterior surface vertebral bodies (sacrum to C2)
- widens caudually
- blends with and reinforces adjacent portion intervertebral discs
- axial stability
- limits extension or excessive lordosis in cervical/ lumbar region
- stronger than posterior longitudinal ligament
posterior longitudinal ligament
- within vertebral canal anterior to spinal cord
- posterior surface of vertebral bodies
- slender lumbar limits ability to restrain disc bulge
- axial stability
