what is an external fixation?
pins are implanted into the bone and held in place ny an external metal frame to prevent bone movement

what is the chief concern in a pelvic fracture?
hemorrhage and shock
what are most compression fractures of the spine associated with?
how are compression fractures ofthe spine treated?
- nonsurgical management = bedrest, analgesics, and physical therapy
- surgical = vertebroplasty and kyphoplasty in which bone cement is injected
paget's disease is characterized by...
an excess of bone destruction and unorganized bone formation
what is the cause of pagets disease?
- genetic predisposition in 10% of patients
- slow viral infection may trigger the disease
- autoimmune dysfunction
what bones does paget's disease affect?
vertebrae, skull, pelvis, femur, and tibia
paget's disease : pathophysiology
- increase in osteoclasts cause bone reabsorption
- increase in osteoblasts cause bone formation
- result is new bone that is structurally weak and enlarged
- deformities and bony enlargement occur
what are s/s of paget's disease?
- none in early stages
- severe and persistent pain that intensifies with weight bearing
- cranial enlargement (headaches, hearing and vision impaired)
- kyphosis, barrel shaped chest, asymmetrical bowing of tibia and femur
- site warm and tender
- slow and incomplete healing of fractures
what is osteomalacia?
- adult bone disease
- vitamin d deficiency resulting in decalcification and softening of the bone
what are s/s of osteomalacia?
- difficulty walking
- fractures and delayed healing
- height loss
which foods contain vitamin d?
eggs, low fat milk, fish, vegetables
what is osteoporosis?
- porus bone with low bone mass

which medications may cause osteoporosis?
- anti-seizure meds
- aluminum-containing antacids
- certain cancer treatments

sardines, milk, ice cream, cottage cheese, yogurt
which dietary factors should be decreased in patients with osteoporosis?
alcohol and caffine
what is osteomyelitis?
bacterial infection of the bone caused by fungus, parasites, and virus
what is hematogenous osteomyelitis?
pathogens are carried in the blood to the bone from sites of infection elsewhere in the body
how can a patient get osteomyelitis?
- from a contiguous infection
- vascular insufficiency
what are risk factors for osteomyelitis?
- intravenous drug abusers
- hemodialysis patients

what does CREST stand for?
- Calcinosis - calcium deposits in the skin
- Raynauds syndrome

- Telangieactasias - dilation of capillaries causing red marks on the surface of the skin
what are clinical manifestations of osteoarthritis?
- joint pain (grating pain that diminishes after rest and intensifies after activity)
- joint stiffness after a period of inactivity
- crepitus (grating sound)
- joint enlargement due to bony hypertrophy
- joint is rarely hot or inflamed
what are systemic signs of rheumatoid arthritis?
- loss of appetite
- low grade fever
what are localized signs of rheumatoid arthritis?
- muscle and joint aches
- muscle joints are inflamed in a symmetrical pattern
- joints become red, swollen, painful, and tender
what is primary gout?
- most common type
- results from inborn errors of purine metabolism or a decrease in renal uric acid excretion
what is secondary gout?
involves hyperuricemia caused by another disease process such as renal insufficiency, multiple myeloma, certain carcinomas
what are clinical manifestations of gout?
- pain, swelling, redness, warmness and stiffness in the affected joint
- inflammation of the tissue around the joint also causes the skin to be swollen, tender and sore
post-op care for a total hip replacement:
- wound care: stitches or staples will be removed 2 weeks after surgery, avoid getting wet, bandage over incision, observe for bleeding
- may have drain in place: monitor output
- assess for neurovascular compromise: color, temp, pulses, cap refill, movement/sensation, compare to non-operative side
- pain: epidural analgesia, pca
progression of activity for a total hip replacement:
- pt gets out of bed the day after surgery and physical therapy is started
- raised toilet seats and chairs to prevent hyperflexion
- a patient with a cemented implant is allowed immediate partial weight bearing (PWB) or full weight bearing (FWB)
- a patient with a noncemented implant cannot tolerate FWB until bony ingrowth occurs
post-op care for a total knee replacement:
- similar to THR
- maintain the knee in a neutral position - not internally/externally rotated
- knee brace
- continuous passive motion device
