1

anatomical leg length diff def

when a physical shortening of a unilateral lower limb exists between the head of the femur and the ankle mortise.

2

functional leg length diff def

Functional, or apparent, limb length inequality can be described as a unilateral asymmetry of the lower extremity without any concomitant shortening of the osseous components of the lower limb

3

when is a leg length discrepancy considered moderate or severe

30-60 mod

60 is severe

4

prevalence range in leg length discrepancy

4-95%

5

giles and taylor - scoliosis and LLI

functional correction occurred with a heel lift (worked in younger age, older age had a wedge shaped VB)

when the difference was > 9 mm there was a scoliotic curve, convex to the short limb side (left side)

6

scoliosis and LLI - the lumbar convexity occurs towards which side?

the short limb side (Hoikka et al, said that may occur on the side of the longer limb)

7

Holmes - IT band syndrome and LLI

7 of 61 cyclicts with knee pain and ITBS also had a leg legnth inequality..

this is irrelevant

8

Subotnick IT band syndrome and LLI

ITBS manifests on shorter limb side

this is so stupid

9

LLI and achilles tendinopathy, relevant?

no sir

10

stress fractures and LLI?

Friberg in finnish army people, doesn't seem related

11

LLI and scitatica

LLI and scitatica

12

LLI and trochanteric bursitis

more likely on short side?

13

gold standard for LLI diagnosis

x-ray, but people will also use scanogram sometimes because it has less error than xray

14

four "direct" measures of LLI

1.ASIS to medial malleolus
2.ASIS to lateral malleolus
3.Xiphoid process to medial malleolus
4.Umbilicus to medial malleolus

15

What did Mann et al say about LLI measurements

no correlation between percentage body fat and differences in rater agreement of LLI

16

how many direct meethods sources of error

6

1.Proximal landmark Right
2.Proximal landmark Left
3.Distal landmark Right
4.Distal landmark Left
5.Measurement Right
6.Measurement Left

17

Ross' method for indirect measurement that he likes

shimming with heel lifts (because palpation and visual estimate is not reliable)

18

most clinically useful way for measuring LLI

the indirect method

19

no matter what is happening in the pelvis, what will be shorter on the short limb side (anatomical difference)

greater trochanter will be lower

20

height of heel lift max for typical shoes

useful up to 12.55mm

21

how long between weeks of changing for lift therapy

every 2 weeks, change should be between 3 to 6mm

22

what % of people got better with heel lift by Friberg

88%
