Flashcards in Day 10 Deck (24):
1

What is characteristic of the L1-L4 articular processes?

The transverse diameter (width between/distance between) superior articular process of an L1-L4 segment will be greater than the transverse diameter (width between/distance between) the inferior articular processes of that same segment.

2

**What is the orientation of the typical lumbar superior articular facet?

backward, upward, medial (BUM); typically concave

3

**What is the orientation of the typical lumbar inferior articular facet?

forward, lateral, downward (FoLD) ; slightly convexity

4

What muscle(s) will attach to the mammillary process?

multifidis and intertransversarii

5

What is the joint classification for the typical lumbar zygapophysis?

synovial plane (diarthrosis)

6

How many joint classification for the typical lumbar vertebra?

four

7

What is the position of the lumbar zygapophysis in children?

the zygapophysis lies in the coronal plane

8

What is the position of the lumbar zygapophysis in adults?

the zygapophysis lies in the sagittal plane for L1/L2, L2/L3, and L3/L4;
the zygapophysis lies in the coronal plane for L4/L5 and L5/S1

9

What names are given to the condition in which one zygapophysis of a vertebral couple lies in the coronal plane or position and the other zygapophysis lies in the sagittal plane or position?

joint asymmetry or joint tropism

10

What is the name(s) of the condition in which the typical lumbar spinous process increases in length due to the aging process?

Baastrup's syndrome or "kissing spines"

11

What is Baastrup's syndrome?

elongation of the lumbar spinous process as a result of aging

12

What muscles will attach to the typical lumbar spinous process?

latissimus dorsi, serratus posterior inferior, iliocostalis lumborum, longissimus thoracis, spinalis thoracis, multifidis, rotator longus, rotator brevis and interspinalis

13

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

six

14

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

two

15

How many fibrous (amphiarthrosis) syndesmosis joint surfaces are present on the vertebral body of L5?

four

16

What joint classifications will be observed at the vertebral body of the fifth lumbar?

cartilaginous (amphiarthrosis) symphysis and fibrous (amphiarthrosis) syndesmosis

17

What muscle(s) attach to the fifth lumbar vertebral body?

psoas major

18

What is the joint classification of the mammillo-accessory ligament?

there is none since it attaches parts of the same vertebra together

19

What muscles may attach to the transverse process of the fifth thoracic vertebrae?

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

20

What ligaments traditionally attach to the transverse process of the fifth lumbar vertebrae?

lumbosacral, iliolumbar and mamillo-accessory ligaments

21

What is the reported angulation and X-ray appearance of the fifth lumbar articular facets?

they lie in the vertical plane and are coronal facets

22

What is the name(s) of the condition in which the L5 spinous process increases in length due to the aging process

Baastrup's syndrome or "kissing spines"

23

**What is the name given to the congenital condition in which the fifth lumbar spinous process is elongated, the sacrum exhibits spin bifid a, and dorsiflexion produces pain?

Knife Clasp Syndrome

24

What muscles will attach to the fifth lumbar spinous process?

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