Bony Lower Extremity

Question 1

Weight transfer

Answer 1

1. Weight of the upper body is transmitted centrally through the vertebral column
2. Divided, and directed laterally by means of the bony arch that is formed by the sacrum and the ilium on each side. The dense bony column for weight transmission through the head of the femur.
3. head of the femur to the shaft
4. Pubic rami form braces that help maintain the integrity of the arch.

Answer 21

Posterior side

Question 22

Gluteus medius placement on a femur

Answer 22

Posteriorly placed

Question 23

Gluteus minimus Placement on femur.

Answer 23

Anteriorly placed

Question 24

Adductor tubercle attachment

Answer 24

Attachment of the hamstring portion of the adductor Magnus to help form the adductor hiatus

Question 25

In a cross-section for the femur, which side is more pointed?

Answer 25

The posterior side- has linea aspera and allows attachment of the quadriceps muscles and the medial compartment and posterior compartment muscles deep fascia will attach to both medial and lateral aspect of the linea aspera Flat anterior surface It is flat anteriorly to allow the attachment of the quadriceps muscles Lateral medial sides are rounded

Question 26

Angle of inclination

Answer 26

Between the long axis of the femoral neck, and then the femoral shaft Varies with age, sex and development

Question 27

Coxa Vara

Answer 27

Angle of inclination is decreased The shaft or the femur deviates towards the midline Mild shortening of the lower limb Limits passive abduction of the hip

Question 28

Coxa valga

Answer 28

Increased angle of inclination Shaft of the femur moves away from the midline Lengthening of the lower limb Limits passive adduction of the hip

Answer 32

Anterior side

Question 33

Fibula cross-section

Answer 33

Pointed anteriorly Rounded posteriorly Rounded laterally

Question 34

Articular facet of the patella

Answer 34

Medial is smaller lateral is bigger

Question 35
