Lumbar IV/Group Curves

Question 1

Main factors in diagnosing idiopathic scoliosis

Answer 1

. Degree
. Balance
. Rotational component of curvature

Question 2

90% of structural curves are convex ___

Answer 2

Right in upper thoracic spine

Question 3

Functional lateral curve

Answer 3

. Seen in unilateral iliopsoas spasm and leg length inequality
. Postural imbalances from hand dominance
. Not fixed, can be improved/corrected
. Treatments: manipulation, heel lift therapy, muscle stretches

Question 4

Wolf’s law

Answer 4

. Functional curve goes unchecked for years

. Causes long term anatomic change in bones

Question 5

Group curve apex segments

Answer 5

. Segment that is rotated into convexity the most

. Sidebent and rotated on opposite sides

Question 6

Group curve crossover point

Answer 6

. Point where scoliosis crosses over from being convex on the right to the left or vice versa
. Important areas to treat bc they are area of high stress
. If it is restricted it can affect the functioning of curves to applied load
. Type 2 dysfunctions common at these points

Question 7

Group curve transition zones

Answer 7

. Areas in spine where AP curve changes direction from lordosis to kyphosis and vice versa
. Area of stress that can affect functioning of curves to applied load

Question 8

C curve

Answer 8

. Does not cross midline (S does)

Question 9

Unlevel sacrum compensation

Answer 9

. Lumbar curvature in frontal plane
. Causes group curve
. Unilateral post. Innominate rotation that gives appearance of short leg

Question 10

Ow group curves chance later in life

Answer 10

. Curves in frontal plane inc. as muscular strength declines
. Spinal curves in sagittal plane change

Question 11

Compensatory pattern for frontal plane asymmetry

Answer 11

. Pos. PSS to one side
. Restriction of thigh abductors on same side as pelvic shift
. Restriction of thigh adductors on contralateral side of PSS
. Deep sacral sulcus on contralateral side of PSS
. Lumbar convexity on contralateral side of PSS
. Tight psoas on contralateral side of PSS
. Tight, ittitable iliolumbar ligament

Question 12

What is the first structure to become painful in patients w/ postural stress

Answer 12

. Iliolumbar ligament

Question 13

Iliolumbar ligament can refer pain where?

Answer 13

. Groin
. SI joint region
. Medial thigh

Question 14

Quadratus lumborum OIAN

Answer 14

O: iliac crest and iliolumbar ligament
I: inf. Border 12th rib and transverse processes of L1-4
A: bilaterally it extends spine, unilaterally it is sidebender and hip hiker
N: lumbar plexus, primarily L1

Question 15

Quadratus lumborum strain

Answer 15

. Can be excruciating

. Sudden movements. Combined bending/twisting motion, coughing and sneezing can cause sharp knife-like pain

Question 16

Quadratus lumborum can refer pain to ____

Answer 16

. Post. And lat. pelvic, gluteal, and hip region

Question 17

What eases pain for quadratus lumborum

Answer 17

. Placing hands on hips and pushing downward

. Transfers weight of upper body directly on hips and off lumbar spine

Question 18

Positive signs of quadratus lumborum dysfunction

Answer 18

. High iliac crest on tight side
. Lumbar convexity to opposite side
. Pelvis on opposite side may tilt downward

Question 19

Where is pain worse on group curve?

Answer 19

Covex (overstretched) side
