Anatomy of Joints : LE X

Question 1

Femoracetabluar Impingment

**

Answer 1

Condition where bony abnormalities of the femur, acetabulum or both result in pain and altered mechanics at the hip joint
Causes impingement and damage to acetabular cartilage

Question 2

Meniscus tears - random

**

Answer 2

Most common knee injury

Athletes susceptible

Question 3

Anterior Cruiciate Ligament Tears

**

Answer 3

ACL - most injured ligament
5-% occur in conjunction with meniscus injury
Tested with Drawer test (testing anterior translation of leg with respect to femur)

Question 4

Ankle Sprains

**

Answer 4

Occurs with excessive motion at ankle
Stretching or tearing of ankle ligaments
Inversion sprain most common, lateral ligaments

Question 5

Hip Joint - def, characteristics

Answer 5

Femur heads + acetabulum of hip joint

Three degrees of motion

Question 6

Hip Joint Ligaments : name, fxn

**

Answer 6

Illiofemoral ligament, Pubfemormal ligament, Ischiofemoral ligament
Primary stabilizers of hip joint

Question 7

Illiofemoral Ligament - location, characteristics

**

Answer 7

between pelvis and femur
Helps you stand upright - maximally taut in extension
Strongest ligament

Question 8

Pubofemoral Ligament

**

Answer 8

pubic part of hemipelvis to femur

taut in abduction (an individual who can abduct like crazy need laxity in this ligament)

Question 9

Ischiofemoral Ligament

**

Answer 9

pelvis and femur

Restrict internal rotation - taut in internal rotation

Question 10

Acetabular Labrum - def., fxn

**

Answer 10

fibrcartilagonous structure around perimeter of the bony acetabulum.
increases congruence btwn joint surfaces = joint stability

Question 11

Ligamentum Teres

**

Answer 11

Inserts into fovea capitis

includes small amount of blood supply to femur

Question 12

Blood supply to head of femur

Answer 12

important - hip fractures - neck of femur break

compromises blood supply to femur

Question 13

Motions of the Hip

**

Answer 13

Extension/Flexion
Abduction/Adduction
Internal Rotation / External Rotation

Question 14

Knee joint - composition

**

Answer 14

Femur and Tibia

Femur and Pattella

Question 15

Valgus - def, if strain

**

Answer 15

`Kneespoint together

Valgus movement restricted by medial collateral ligament

Question 16

Varus

**

Answer 16

Knees point apart

Verus movement restricted by lateral collateral ligament

Question 17

Dorsiflexion actions

Answer 17

Rise up on heels

Question 18

Plantarflexion actions

Answer 18

Rise up on toes

Question 19

Inversion - action, location, sprains

**

Answer 19

soles of foot move medially
@ Subtalar joint (not ANKLE joint)
sprains more common, injures lateral ligaments

Question 20

Foot Arches - fxn. ligaments

**

Answer 20

Absorb shock and distribute forces during activity
supported by foot ligaments
Long plantar ligament
Short Plantar Ligament
Calcaneoavicular ligament

Question 21

Ligaments of ankle - Lateral + others

**

Answer 21

*Anterior talofibular ligament
*Calcaneofibular ligament
Deltoid Ligament
Posterior Talofibular Ligament

Question 22

Malleoli can be fractured

Answer 22

KNOW

Question 23

Knee support

**

Answer 23

Lateral Collateral Ligament
Medial Collateral Ligament
Anterior Cruciate Ligament
Posterior Cruciate Ligament
Menisci - support and shock absorbance - medial susceptible to injury from sudden extension or rotation while leg fixed

Question 24

Ankle Joint - a.k.a, compoments. motions

**

Answer 24

Talocural
Talus and Tibia
Mallelous (Medial and Lateral)
Plantar and Dorsiflexion
