Flashcards in Measurements Deck (52):
1

patella alta

greater than 1:1 (ratio of patella tendon length to the height of the patella)

2

patella baja

less than 1:1 (ratio of patella tendon length to the height of the patella)

3

normal angulation of the femoral neck after 8 years of age

15 degrees

4

anteversion/retroversion

increase from 20 degrees in the angulation of femoral neck (anteversion)

decrease - retroversion)

5

measuring tibial torsion

pt kneels on stool with foot relaxed
line drawn from center of thigh and lower leg, bisecting the middle of the heel and the bottom of the foot

another line starts at center of middle toe and crosses the heel

angle of more or less than 15 degrees measures tibial torsion

6

internal rotation of hip caused by

week external rotators or foot pronation

7

determining patellar tilt

if the heigh of the medial border is more anterior than the lateral than a positive lateral tilt exists

8

functional leg length

umbilicus to medial malleolous

9

true leg length

ASIS to lateral malleolous

10

girth measurements (knee)

8-10 cm above joint line, 2 cm above patella, joint line (tibial plateau), tibial tubercle, belly of gastroc

11

Q-Angle

draw line from middle of patella to the ASIS

draw line from tibial tubercle through center of patella

measured with the knee fully extended and the knee flexed at 30 degrees

12

normal Q angle

10 degrees for males
15 degrees for females

13

pathological Q ANGLE

exceed 20 degrees

can cause improper patellar tracking in the femoral groove

14

A Angle

measures the patella orientation to the tibial tubercle

line that bisects the patella longitudinally and a line from the tibial tubercle to the apex of the inferior pole of the patella

15

pathological A angle

greater than 35 degrees = patellofemoral pathomechanics

16

apparent discrepancy (leg length)

leg shortening can occur as a result of lateral pelvic tilt (obliquely) or from flexion or adduction deformity

17

function discrepancy (leg length)

deformity (ex. valgus knee) that cannot be treated or fixed

18

anatomical discrepancy

shortening equal throughout the femur or lower leg

19

angle of inclination

angular relationship of the femoral head and the femoral shaft

20

increase in the angle of inclination

coxa valga, 140 or greater

21

normal angle of inclination

about 130

22

decrease in the angle of inclination

110 or less coxa vara

23

coxa valga associated with

genu varum or laterally positioned patellae, reduced mechanical adv of glute mede

24

coxa vara associated with

genu valgum or medial patella (squinting), reduced mechanical adv of glute mede

25

anteverted femur

increases of greater than 20 degrees (angle of torsion)

causes internal femoral rotation, squinting patellae, toe in (pigeon toed), decrease in external rotation, and an increase in internal rotation

26

retroverted femur

angel of torsion is less than 15 degrees

results in toe out, lateral patella, decrease in hip internal rotation and an increase in external rotation.

27

Nelaton's line

draw from ASIS to ischial tuberosity

location of greater tuberosity superior to this line indicates coxa vara

28

T3 lines up with

medial border of the scapular spine

29

T7 lines up with the

inferior angle

30

C7

prominent bulge seen in neck flexion

31

T1

right below C7, does not disappear in ext

32

C1

finger's breadth below mastoid processes

33

L3

normally lines up with umbilicus

34

L4

level with iliac crest

35

L5

dimples

36

S2

increase pressure on lateral joint, medially - tensile forces, foot pronation, internal tibial rotation, medial patellar position, internal femoral rotation (anteversion)

52

tibial angled laterally more than 5 degrees (relative to femur

increased tension on lateral forces, compression on medial joint structures, foot supination, external tibial rotation, lateral patella position, external femoral rotation (retroversion)
