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

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

34

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.
