Anatomy
Vertebrae
• 7 Cervical
• 12 Thoracic
• 5 Lumbar
• 5 Sacral
• 4-6 Coccygeal
• Same structure, but different localisation,
shape and function!
• Anatomical – functional segment
3
Joints of the vertebrae
ALL JOINT TYPES CAN BE FOUND
• SYNDESMOSIS (ligamentous)
• SYNCHONDROSIS (fibro cartilage)
• SYNOSTOSIS (bone)
• REGULAR JOINT (joint capsule, hyalin
cartilage, synovial membrane, synovial
fluid)
4

Ortopédiai Klinika 5
SYNDESMOSIS
• Anterior and posterior longitudinal
ligament
• Yellow ligament
• Interspinous ligament
• Intertransversal ligament

SYNCHONDROSIS
INTERVERTEBRAL DISC
(anulus fibrosus, nucleus pulposus)

REGULAR JOINTS
Joint capsule, hyaline cartilage, synovial
membrane and fluid!

Movements of the spine
• Anteflexion
• Retroflexion
• Lateralflexion (left and right)
• Torsion (left and right)
• Pairs of wertebrae –anatomical and
functional segment
12
Functions of the vertebral disc
• Stability - Stabilizing role
(Keeps the ligaments tight by keeping the
distance between the vertebrae constant)
• Flexibility - Buffer role.
13
Degenerative changes
• CAUSE: disc prolapse and protrusion.
• Disc flattening causes pain.
• Bone growth at the edge of the vertebrae
• Stability of spine – tension of ligaments
• „Vicious cycle”.

Degenerative changes
DISEAESES OF THE
VERTEBRAL DISCS
• PROTRUSION -anulus fibrosus intact
• HERNIA -anulus fibrosus not intact -
nucleus pulposus leaks out
• RUPTURED HERNIA- small amount
nucleus pulposus leaks out and loses
connection with remaining

Degenerative changes
Definition
• SPONDYLOSIS: degenerative changes
between two vertebral bodies with
spondylophyte formation.
• SPONDYLARTHROSIS: degenerative
changes in the facet joints between two
vertebrae.

Spondylosis
DE OEC
Ortopédiai Klinika 26
CLINICAL SIGNS (lumbago)
• The mobility of the affected vertebrae
decreases
• The affected area is tender
• The spinous processes are sensitive to touch
• Spastic paravertebral muscle
• Antalgic posture
• Pain on axial loading
27
CLINICAL SIGNS (sciatica)
• The mobility of the affected vertebrae
decreases
• The affected area is tender
• The spinous processes are sensitive to touch
• Spastic paravertebral muscle
• Antalgic posture
• Pain on axial loading
• + SIGNS OF NERVE ROOT
IRRITATION!!!(radiating pain, sensory
loss, paresis, reflex difference) 28

RADIOLOGICAL SIGNS
• Decreased intervertebral space.
• Degenerative bone deposits on the edge
of the vertebrae (spondylophytes).
• Degenerative facet joint changes.
• Stenosis of intervertebral foramen
• Spinal stenosis.
30

TREATMENT
• BEDREST (IN KYPHOSIS)
• PHYSICOTHERAPY
• NSAID, MUSCLE RELAXANTS!!
• LOCAL STEROID
• BRACE
• SURGERY: stabilization,discectomy, etc.
32
Spinal stenosis
• Narrowing of the spinal canal causing ischemia in the cauda equina.
• reason: spondylophyte, facet joint arthrosis, discus hernia…etc.
33
Spinal stenosis
• Symptoms: Pain during standing or walking radiating into the lower extremities, which disappears after sitting or bedrest= neurologic claudication.
• Treatment:conservative (see above) or surgical decompression

Ankylosing spondylitis
Bechterew’s disease
• Chronic inflamation of the entire spine and
sacroiliac joints, which characterized by
calcification of ligaments and joint
capsules (regular joints!)

Spondylolysis, spondylolisthesis
DE OEC
Ortopédiai Klinika 42
Spondylolysis - a defect in the pars
interarticularis of the vertebral arch
Spondylolisthesis - is the forward or
backward displacement of a vertebra

Disorders of segmentation
Sacralisation – partial or total fusion of fifth lumbar
vertebra and sacrum.
Lumbarization – lack of the fusion inside the
sacrum.

Scheuermann disease
• Juvenile osteochondrosis
• 10% occurrence in adolescence
• Blood supply problems to the end plate results in
disc herniation -SCHMORL- nodes
51 DE OEC

Imaging
• X-RAY: uneven endplate, Schmorl nodes,
increased kyphosis, anterior wedging of
vertebrae.
