Spine Flashcards
The zypophyseal joints are oriented at
45° to the horizontal plane
superior facet faces posteriorly and superiorly
Inferior facet faces anteriorly, and inferiorly
Zygapophyseal joints, and uncovertebral joints make an important contribution to
Stability by restraining excessive movement, and there by protecting the IBD from severe torsional strain
ZPJs in the cervical spine, do not protect
IVD as much as they do in lumbar spine
Uncovertebral joints
joints of luschka
lateral interbody joints
The superior aspect of each lateral vertebrae, a process grows upwards towards the vertebral body above in the loose vascular fibrous tissue
the uncinate processes grow upwards from the
Superior aspect of each lateral vertebral margin towards the vertebral body above
The uncinate processes grow from
Vascular fibrous tissue lateral to the annulus
the uncinate processes have grown enough by
age 7-8 years to form a sort of adventitious joint UV joint on each side of the disc
the UV joint is lined by
Fibrocartilage and a thin fibrous capsule limits each joint cleft laterally
The UV joints do not have
Synovial fluid
The UV joints have
Interstitial fluid around the joints and surrounding surfaces
Stability is more dependent upon
Integrity of a zygapophyseal joints and posterior musculature and ligaments
Rather than the UV joints
Presence of a UV joints, results in medial extension of
horizontal fissures into the annulus from the UV joints
in the cervical spine, we don’t see prolapses, extrusions, or sequestration of nuclear material because
The presence of a UV joints and development of the bivalve disc
C2 disc referral pattern
Only disc that refers pain superiorly into the head
may be common source of headaches
C-5, C6 and C7 discs referral pattern
Lower motion segments
Refer into UE and usually proximal to the elbow
