Tinel's sign
Tx of Carpal Tunnel
- intraarticular injections of corticosteroids or oral corticosteroids
- application of wrist splints or prevent hyperextension and prolonged flexion of the wrist
Ineffective Tx of Carpal Tunnel
- yoga, laser therapy and ultrasound therapy are ineffective, as are use of NSAIDs, diuretics and Vitamin B6
dupuytren's disease
slowly progressive contracture of the palmar fascia

causes flexion of the 4th and 5th fingers and freq. middle finger.

inherited autosomal dominant trait > 50 y.o.

experiences dull aching discomfort, morning numbness, cramping and stiffness in the affected fingers.
what can prevent contractures if pt. is at risk
finger stretching exercises or intranodular injections of corticosteroids
how often are neurovasc assessments done post-op hand surgery?
every hour for the first 24 hours following surgery
should the pt elevate the hand below or above the elbow?
above the elbow
after hand surgery, how should the pt. be instructed to bath?
keep the dressing dry by covering it with a secured plastic bag
plantar fasciitis is experienced when?
the first steps in the morning
area of hyperkeratosis (overgrowth of a horny layer of epidermis)

produced by internal pressure (underlying bone is prominent bc of a congenital or acquired abnormality, commonly arthritis)

or external pressure from ill fitting shoes
hallux valgus aka

deformity in which the great toe deviates laterally

factors contributing to a bunion
- hereditary
- ill fitting shoes
- gradual lengthening and widening of foot associated with aging
- osteoarthritis
pes cavus
aka clawfoot

foot with abnormally high arch and fixed equinus deformity of the forefoot

Charcot-Marie-Tooth disease (peripheral neuromuscular disease associated with familial degenerative disorder), DM, and tertiary syphilis are common causes.
which bone disease is the most prevalent in the world?
precursor to osteoporosis
genetic risk factors for osteoporosis
caucasian or asian
family hx
small frame

- predisposes to low bone mass
age risk factors for osteoporosis
advanced age
low testastorne in men
decreased calcitonin

- hormones (estrogen, calcitonin, testosterone) inhibit bone loss)
nutrition risk factors for osteoporosis
- low calcium intake
- low vitamin d intake
- high phosphate intake (carbonated beverages)
- inadequate calories

(reduces nutrients needed for bone remodeling)
physical exercises risk factors for osteoporosis
lack of weight bearing exercises
low weight and body mass index

- bone need stress for bone maintenance
lifestyle choices risk factors for osteoporosis
lack of exposure to sunlight

- reduces osteogenesis in bone remodeling
medication risk factors for osteoporosis
anti-seizure meds
thyroid hormone

- affect calcium absorption and metab
comorbidity risk factors for osteoporosis
malabsorption syndrome
renal failure

-- affect calcium absorption and metab
primary osteoporosis occurs in women and men when?
after menopause (between ages 45 - 55 years old)

men - later in life
secondary osteoporosis
result of medications or other conditions and diseases that affect bone metabolism

discontinuation of meds halts osteoporosis progression but will not restore lost bone mass
post-menopausal women and the elderly need to consume how much calcium daily?
approx. 1200 mg

quantities larger than this for this population can lead to kidney stones
what does PTH do when it increases with age?
increases bone turnover and resorption (bad)
the RAI level of calcium for all individuals is
1,000 - 1,200 mg / daily
the recommended vitamin D intake for adults 50 y.o. and older is
800 - 1,000 IU daily
what should calcium supplemants be taken with?
a meal to increase absorption or a beverage high in vitamin C
calcium and vitamin D supplements should not be taken with ____________ at the same time of day?
how should patients take biphsophate supplements?
on an empty stomach
arising in the morning
full glass of water
sit upright for 30 - 60 minutes

-after administration
Calcitonin for inhibition of osteoclasts should be administered by
nasal spray or subcut / IM injection

SE: nasal irritation, flushing, GI disturbances, urinary frequency.

pts with seafood allergies should not take calcitonin
metabolic bone disease

inadequate mineralization of bone

faulty mineralization causes softening and weakening of skeleton, causing pain tenderness to touch and bowing of the bones & patho fractures.
what is the primary defect in osteomalacia?
deficiency of activated vitamin D (calcitriol) which promotes calcium absorption from GI tract and facilitates mineralization of bone.

paget's disease of the bone
localized rapid bone turnover

most commonly affects
- skull
- femur
- tibia
- pelvic bones
