Clinical Applications Skeletal System Clinical Applications

Osteoporosis 20 million people suffer from it (250,000 hip fractures a year) Decreased bone mass Increased susceptibility to fracture Hormones effect osteoblast production Afflicts entire skeletal system

Risk factors Body build (shorter females at greater risk) Weight (adipose produces estrone) Smoking (decreases estrogen levels) Calcium deficiency or malabsorption Vitamin D deficiency Exercise (sedentary more at risk) Certain drugs (alcohol, diuretics, cortisone, tetracycline) Premature menopause Family history

Paget's Disease Accelerated remodeling of bone tissue Osteoclast resorption massive Osteoblast formation extensive Irregular thickening and softening of bones Greatly increased vascularity, especially in skull, pelvis, and extremities link

TMJ Temporomandibular joint disease Often caused by trauma to jaw joints, genetics, or dental procedures Symptoms include facial pain, headaches, grinding of teeth, popping of jaw, and swallowing difficulties Not well defined in medical community

Epidural anesthesia Repeated doses of a local anesthetic in the epidural space of he spinal area Produces almost pain- free awake state throughout labor and birth

Advantages Freedom from pain during labor and birth Does not produce drowsiness Little medication reaches baby May provide extra confidence

Disadvantages May slow labor Must remain in bed IV required Frequent monitoring required Catheterization required Probable forcep delivery Can interfere with maternal-infant bonding Totally dependant on hospital staff Extremely rare, serious risks to spine

Kyphosis: “Hunchback” Exaggeration of the thoracic curve

What causes kyphosis? Tuberculosis of spine- Degeneration of discs vertebral bodies partially collapse Degeneration of discs Rickets (lack of vitamin C) Poor posture Advanced osteoporosis

Lordosis: “Swayback” Exaggerated lumbar curve Exaggeration of the lumbar curve Exaggerated lumbar curve

What causes lordosis? Pregnancy or extreme obesity Result of increased weight gain Pregnancy or extreme obesity Poor posture Rickets Tuberculosis of spine link

Scoliosis Lateral curvature Lateral bending of the vertebral column link Lateral bending of the vertebral column Lateral curvature

What causes scoliosis? Congenital malformed vertebrae (birth defect) Chronic sciatica (pain down leg) Paralysis of muscles on one side of backbone Poor posture One leg shorter than other

Carpal Tunnel Syndrome median nerve which runs through wrist to hand becomes compressed involves narrow bony passage in wrist called carpal tunnel, through which nine tendons and median nerve must pass

Bunion Deformity of great toe Lateral division of proximal phalanx Can be inherited or caused by tight fitting shoes

Flatfoot Bones composing arch of foot held by ligaments and tendons Weakened ligaments and tendons causes arch to “fall” Caused by excessive weight, postural abnormalities, weakened tissue, and genetic disposition
