Ligaments

Question 1

Anterior Longitudinal Lig

Answer 1

Resist Extension and excessive Lordosis
Greatest tensile strength in lumbar region
Non painful if injured

Question 2

Posterior Longitudinal Lig

Answer 2

Resists Flexion/ Traction
Weak in lumbar region= High incidence of HNP

Question 3

Ligamentum Flavum

Answer 3

Resists Flexion, tight in all positions except extension
Strongest in lumbar region, weakest in mid-cervical

Question 4

Interspinous Lig

Answer 4

Resists hyper flexion, Palpable tenderness indicates hyper mobility or instability

Question 5

Supraspinous Lig

Answer 5

Resists hyper-flexion
No direct attachment at L4/L5

Question 6

Intertransverse ligament:

Answer 6

Resists contralateral flexion (SB)

Question 7

Illiolumbar ligament: Anterior

Answer 7

Resists ipsilaterally SB, ant translation of L5

Question 8

Illiolumbar Lig: superior:

Answer 8

Prevents flexion

Question 9

Illiolumbar Lig: Inferior

Answer 9

Taught in extension

Question 10

Illiolumbar ligament: Posterior

Answer 10

Prevents flexion, stabilizes L5, resists SB @ L4

Question 11

Anterior SI LIGS:

Answer 11

Limits ALL motions

Question 12

Posterior SI LIG:

Answer 12

Limits sacral counter nutation (anterior illiac rotation)

Question 13

INTEROSSEUS SI LIG:

Answer 13

Limits anterior and inferior movements of the sacrum
Most important ligament of SIJ

Question 14

Sarcotuberous Lig:

Answer 14

Forms inferior border of lesser sciatic notch
Limits Sacral nutation (posterior illiac rotation)

Question 15

Sarcospinous Lig:

Answer 15

Forms inferior border of greater sciatic notch
Limits sacral nutation
