axillary border of scapulae

Question 5

Deformities seen with osteomalacia

Answer 5

in weight bearing bones
protrusio-acetabuli
bowing of the femur or tibia
kyphoscoliosis

Question 6

Rickets

Answer 6

Childhood equivalent of osteomalacia in an adult
6-12 months of age
due to a deficiency of Vitamin D, calcium, phosphorous, or sunlight

Question 7

Clinical Findings of Rickets

Answer 7

muscle tetany
bone pain
irritability
weakness
delayed development
small stature
bone deformities

Question 8

soft tissue swelling around growth plates is associated with:

Answer 8

Rickets
secondary to hypertrophied cartilage
“rachitic rosary” costochondral bumps on the anterior rib cage

Question 9

Growth Plate changes seen with Rickets

Answer 9

cartilage cells grow normally, but fail to calcify
resulting in a generalized lucency due to the increase in uncalcified osteoid
healed when an opaque metaphyseal line is visualized
