Fryette's Flashcards
Supraspinous ligament
Connect spinous processes
Interspinous ligament
Between spinous processes
Intertransverse ligament
Between transverse processes
Anterior longitudinal ligament
Anterior of vertebral body
Posterior longitudinal ligament
Posterior of vertebral body
Ligamentum flavum
Connect laminae
Nuchal ligament
Fans out from the skull across cervical and upper thoracic spinous processes
Radiate ligament of head of rib
Ribs to vertebral facets/demifacets
Costotransverse
Ribs to transverse processes
Iliolumbar
Ilium to L4,5
Back muscles that contract during extension
Erector spinae, splenius capitis and cervicis, multifudus lumborum, semispinalis capitis and cervicis
Ligament that stretches during extension
Anterior longitudinal ligament
Back muscles and ligaments that stretch during flexion
Muscles that contract during extension, supraspinous ligament, interspinous ligament, ligamentum flavum, nuchal ligament
Motion of vertebrae described in relation to …..
Vertebra below
Fryette’s I
When thoracic and lumbar spine are in neutral, the coupled motion of side-bending and rotation for a group of vertebrae occur in opposite directions
Fryette’s II
When thoracic or lumbar spine is sufficiently flexed or extended, the coupled motions of side-bending and rotation occur in the same direction (single vertebral unit)
Fryette’s III
Initiating motion of a vertebral segment in any plane of motion will modify the movement of that segment in other planes of motion
Fryette’s Type I influenced by….
Vertebral bodies and discs
Position of ease
Direction of ease (where things got stuck or motion preference)
Restrictive barrier
Direction it won’t go easily
Fryette’s Type II infleunced by….
Facets
Flexion…
Facets locked open causing rotation away from open facet
Extension….
Facets locked closed causing rotation towards that facet
Capsular pattern
Motion restricted in both paired directions seen in pathologic conditions like arthritis
Rule of threes
T1-3: transverse process directly lateral to spinous process (also T12)
T4-6: transverse process halfway between the spinous process of that segment and that of the segment above (also T11)
T7-9: transverse process directly lateral to spinous process of segment above (also T10)
