LangerÕs/Tension Lines
|
lines of tension in the dermis caused by directionality of collegen fibers which surgical incisions should follow to decrease wound gaping and increase rate of healing (p. 13)
|
|
|
Stretch Marks
|
damage of collagen fibers in the dermis due to increase in skin tension/stretching from pregnancy or weight gain. They fade but never completely go away (p. 13).
|

|
Accessory/Supernumery Bones
|
develops when there is failure of all ossification centers fusing together to form a single bone. Accessory bones are not part of the main bone. They are common in the skull (wormian bodies) and in the foot (p. 15).
|
|
|
Heterotopic Bones
|
formation of bones in improper regions of the body usually due to increased stress in the area especially muscles (riderÕs bones) (p. 15).
|
|
|
Bone changes
|
atrophy due to decreased use hypertrophy due to increased use and applied pressure ; reduction of a fracture: bringing of the two side of a fracture together ; collar of callus: ring of collagen secreted by fibroblasts that will eventually calcify ; greenstick fractures: fractures involving an incomplete fracture of the bone and bone bending which is often seen in young children due to increased levels of cartilage in bones (p. 18) ; osteoporosis: reduction in the organic and inorganic components of bone leading to atrophy and brittleness of the bones (p. 18).;

|
|
Sternal Puncture
|
removal of red bone marrow from the medullary cavity of the manubrium of the sternum used to treat leukemia patients (p. 18).
|
|
|
Avascular Necrosis
|
loss of arterial blood supply to the bone resulting in cell death.a. osteochondroses: pediatric conditions involving the avascular necrosis of bone with no known etiology.;
|
|
|
Displaced epiphyseal plate
|
separation of the epiphyseal plate sometimes mistaken for a fracture often seen in children.
|
|
|
Fontanelles
|
areas of CT on a newbornÕs skull not covered by skull bones or sutures; bulging Ð increased intracranial pressure; sunken Ð dehydration.
