Abnormal Bone Growth And Fractures Flashcards
Pituitary growth failure
Not enough growth hormones
Body parts are disproportionately smaller
Can be cured with synthetic growth hormone
Acromegaly
Growth hormone when epiphyseal plates close
Bone gets thicker
Parathyroid hormone
Regulates calcium ion metabolism
Makes osteoclasts erode bone
Enhances calcitriol and calcium absorption in intestines
Increases the release of calcitriol and stimulates calcium reabsorption in kidneys
Calcitonin
Does the opposite of calcitriol
Is an inhibitor
Transverse
Break along long axis
Spiral
From twisting bone
Spread along length
Displaced
Abnormal bone arrangement due to stress
Compression
Vertebrae under extreme stress
Greenstick
In children
One side of shaft broken
Other side is bent
Comminuted
Shatter affected area producing fragmemnt
Epiphyseal
Where bone matrix is calcifying
A clean transverse fracture of this type heals wells
Can stop growth
Pott
Ankle and leg bones
Colles
Distal radius
