The Facets

Question 1

Capsular ligament loosest in the Cervical region where there is largest ROM

Answer 1

Butt et al., (2015)

Question 2

Capsular ligament is a significant stabiliser of the facets, rotation significantly increases if it is removed, it is thicker anteriorly

Answer 2

Butt et al., (2015)

Question 3

Presence of intra-articular synovial folds which may help to distribute loads within the facets over a greater surface area

Answer 3

Jaumard et al., (2011)

Question 4

Stages of whiplash

Answer 4

Grouer et al., (1997)

Question 5

Implication of ALL as a mechanism of whiplash injury

Extended to levels of pathological strain first in C4-5 then spread

Answer 5

Ivancic et al., (2004)

Also Stemper et al., (2006)

Question 6

LBP a common problem which is often multi-factorial

Facet joint pathology a contributing factor in 15-52% but prevalence of isolated facet joint pain is low at 4%

Answer 6

Binder, (2009)

Question 7

Function of the facets
Bony pillars support compressive loads
Capsular ligament resists tensile forces

Answer 7

Jaumard et al., (2011)

Question 8

Facets guide and constrain motion of the spine whilst facilitating transmission of load through it.
Prevent 2 adjacent vertebrae from engaging in relative motions that could overload and damage surrounding structures

Answer 8

Jaumard et al., (2011)
