Flashcards in Atypical Lumbar Vertebrae L5 Deck (21):
1

What is the appearance of the fifth lumbar vertebral body fro the lateral view

anterior height is greater than posterior height by several millimeters; it appears to form a wedge on a lateral x-ray view

2

how many synovial joint surfaces are present at the fifth lumbar vertebral body

none

3

how many fibrous (amphiarthrosis) syndesmosis joint surfaces are present on the L5 vertebral body

four

4

how many joint surfaces are present on the vertebral body of the fifth lumbar

six

5

how many cartilaginous (amphiarthrosis) symphysis joint surfaces are present on the vertebral body of L5

two

6

what muscles attach to the fifth lumbar vertebral body

psoas major

7

What are the atttachment sites of the superior corporotransverse ligament at the L4-L5 intervertebral foramen

L4 vertebral body and L4-L5 intervertebral disc to the transverse process of L5

8

What are the attachment sites of the inferior corportransverse ligaments at the L4-L5 intervertebral foramen

L5 vertebral body and L5-S1 intervertebral disc to the transverse process of L5

9

What characteristic of the L1-L4 pedicle may be used to differentiate it from the L5 segment

on cranial view, the lateral surface of the pedicle is apparent on a L1-L4 segment. At L5 the transverse process originates from the vertebral body, pedicle and lamina-pedicle region

10

What is the generic direction and length of the fifth lumbar transverse process

it is directed straight lateral and is the shortest of all lumbar transverse process

11

What accounts for the shortness of the L5 transverse process

the hip/innominate bones diminish the available space in the transverse plane

12

What parts of the lumbar transverse are homologous to the cervical transverse process parts

L: transverse tubercle, C: anterior tubercl
L: transverse process, C: costal element
L: accessory process, C: posterior tubercle
L: transverse process origin, C: true transverse process

13

What muscles may attach to the transverse process of the fifth lumbar vertebra

psoas major, quadratus lumborum, longissimus thoracis, rotator brevis, rotator longus and intertransversarii

14

What ligaments traditionally attach to the transverse process of the fifth lumbar vertebra

lumbosacral, iliolumbar and mammillo-accessory ligaments

15

What is the orientation of the fifth lumbar superior articular facet

BUM backward upward medial, typically concave

16

What is the orientation of the fifth lumbar inferior articular facet

FoLD forward lateral and down significant convexity

17

What is the name given to the congenital condition in which the fifth lumbar spinous process is elongated, the sacrum exhibits spina bifida, and dorsifelxion produces paind

Knife clasp syndrome

18

What muscles will attach to the fifth lumbar spinous process

latissimus dorsi iliocostalis lumborum
longissimus thoracis, multifidis,
rotator longus, rotator brevis and interspinalis

19

How many synovial joints are maximally observed at each lumbar vertebra

L1-L5 four each

20

How many joints are traditionally observed at each lumbar vertebral body

L1-L5 six each

21

What is the inferior articular facet orientation at each lumbar vertebrae

FoLD forward lateral down
