Joints Of The Lower Limb

Front 1

Hip joint
type of joint
movements

Back 1

The hip is the synovial ball and socket joint between the head of the femur and the acetabulum of the pelvic bone.

Movements permitted are flexion, extension, abduction, adduction, medial and lateral rotation, and circumduction

The socket of the hip is deep compared to the glenoid of the shoulder and its general design is optimized for stability during weight bearing at the expense of mobility

Front 2

Acetabulum composition

Back 2

The acetabulum is composed of the ilium, ischium & the pubis bones

Front 3

Transverse acetabular ligament
function

Back 3

Transverse acetabular ligament bridges the acetabular notch, which is the inferior region of the acetabulum absent of articular cartilage

Front 4

Ligament attaches to the fovea of the femur?

Back 4

Ligament of the head

Front 5

Illiofemoral ligament
Names
What motion does this limit in the limb?

Back 5

Y ligament
Y ligament bigalow
Fibers most taught when femur is extended.
Limits range of extension motion

Front 6

What nerve is commonly compressed in a dislocation of the hip joint in a car crash

Back 6

sciatic n.
may be compressed or stretched

Front 7

Blood supply to the femoral head

Back 7

medial & lateral femoral circumflex arteries.
branch from the deep artery of the thigh (deep femoral).

There is also an artery to the head of the femur branching from the obturator artery.

Obturator artery travels within the ligament to the head of the femur, it is small and not as important as the medial femoral circumflex in supplying the head of the femur

Front 8

Pt. found on back external rotation of limb what type of fracture

Back 8

Femoral neck fracture
Osteoporosis

Front 9

Femoral neck fracture

Back 9

Fractures of the femoral neck are quite common in persons older that age 60 & are more frequent in females than males due to a higher incidence of osteoporosis
They are not common in most contact sports due to age of participants, but can occur during figure skating, equestrian events, race-car accidents, etc.

The affected limb is often found in a position of external rotation due to the pull of the gluteal muscles, and the limb appears shortened – this is not well demonstrated in this illustration as the women is on her side and her distal femur is adducted

Front 10

What is the knee joint ?
Movement

Back 10

Synovial - Modified hinge joint
flexion, extension, gliding and rotation

Front 11

Anastamosis of arteries around the knee - where do these arteries arise?

Back 11

5 Genicular arteries originate from the popliteal artery and the femoral artery.

Branches from the deep femoral and anterior tibial arteries also contribute to the network of blood vessels around the knee

Front 12

Lateral knee ligament

Back 12

lateral (fibular) collateral ligament
attaches to the lateral epicondyle of the femur and the head of the fibula.
It is not attached to the lateral meniscus and is separated from it by the popliteus tendon
Round in form.

Front 13

What will a lateral blow to the knee insult?

Back 13

The medial collateral ligament when foot is planted on floor

Front 14

Lateral meniscus attachments

Back 14

tendon of the popliteus muscle

Not attached to lateral collateral ligament

Front 15

Location of Dorsiflexion and plantar flexion

Back 15

distal tibiofibular joint

Front 16

Transverse Tarsal Joint
composition
movements

Back 16

was called the mid tarsal joint
taleocalcaneaonavicular joint
calcaneocuboid joints combined
Inversion/Eversion
Pronation/ Supination of forefoot
