Musculoskeletal and Immune Disorders Flashcards
What is an arthrogram?
A radiographic exam where contrast medium or air injected into joint cavity and joint is moved through ROM as series of x-rays taken, used to diagnose trauma to joint capsule or ligaments
What is an arthroscopy?
A radiographic exam where contrast medium or air injected into joint cavity and joint is moved through ROM as series of x-rays taken, used to diagnose trauma to joint capsule or ligaments
What do the scores of a bone density scan show?
Bone density scan measures the bone’s mineral density and compares in the normal to produce a “T-score.” A score of 0 means the bone density is equal that of a normal healthy adult. Scores of 1-2.5 mean low bone mass, score lower than 2.5 means osteoporosis.
What is a bone scan?
A test in which a radioisotope is injected IV, it collects in areas of abnormal bone metabolism and some fractures (the isotope is excreted in urine and feces within 48 hrs. and is not harmful). Encourage fluids post exam to promote excretion.
Why do we monitor alkaline phosphatase levels?
Alkaline phosphatase is a protein found in all body tissues and particularly high in the liver, bile ducts and bone. In association with the bone disorders indicate that there are high levels of osteoclasts being produced; this may be due normal growth and repair due to a fracture or to disorders such as bone cancer.
What is a myelogram?
dye or air is injected into the subarachnoid space to detect abnormalities of spinal cord and vertebrae. Need to be well hydrated for at least 12 hours. Post procedure if air is used keep head lower than trunk, if water based dye is used elevate HOB 15-30 degrees, if oil base dye used keep the client flat.
What nerve is being compressed leading to carpal tunnel?
Median nerve
What is Thenar?
“Thenar” wasting (muscle of pad of thumb), weakness of hand with decreased grip and decreased sensation.
When do we look out for Tinels sign?
To diagnose carpal tunnel syndrome, Tap the volar surface of wrist, positive if there is tingling. Phalens maneuver is when patient Flex wrists and hold 60 seconds, positive if symptoms of tingling and numbness
How should patients with carpal tunnel sleep at night?
With a Cock-up splint to affect wrist at night to prevent hyperflexion
What is a strain?
Excessive stretching of muscle or tendon. Tx with cold & heat, exercise with activity limitation, NSAIDs, muscle relaxants. If muscle or tendon torn then surgical repair required.
What is a sprain?
Excessive stretching or bending of a ligament, usually from a twisting motion, into a position it was not designed to move. Characterized by pain & swelling. Tx with RICE (rest, ice, compression, elevation). If there is a tear then casting may be required, for severe ligament damage surgery required
What are the different types of fractures?
Simple or closed-No break from the bone to outside body
Open or Compound-Has an external wound (high risk of infection/osteomyelitis)
Comminuted-Bone breaks into many small pieces
Displaced Bone fragments separate and are deformed
Impacted Bone fragment is forced into another bone or bone fragment
Non-displaced After fracture bone sections maintain normal alignment
What do we do first in fracture treatment?
Assess ABCs first since may have been associated with trauma
What are some treatments for fractures?
Immediate immobilization by splinting limits muscle spasm, decreases angulation and prevents further injury
For exposed bone cover with clean (sterile preferred) dressing and prevent reentry of contaminated bone into wound if possible
Reduction of bone is the restoring of displaced bone segments to normal position.
Closed reduction: restore bone alignment by manual manipulation; casting may be required after procedure
Open reduction: surgical realignment of the bone. Internal or external fixation devices, traction or casting may be used post procedure.
What device is non-cirumferential?
Non-circumferential (prevents pressure and skin breakdown)…splints
Which is the device that involves a Metal system of rods and pins inserted through the bone are used to maintain fracture fragments?
External fixation devices
Which device uses plates and screws outside the bone or with a rod inside the bone. May involve the removal of damaged bone and replacement with a prosthesis?
Internal fixation devices
What is a skeletal traction?
mechanically applied to the bone with pins, wires or tongs (i.e. Steinmann pin, Kirschener’s wire or crutchfield tongs). Weights are then attached to maintain alignment. Often used femur, tibia, and c-spine
What is an example of a skin traction?
Bucks extension traction (used to alleviate muscle spasms, immobilize lower limb by maintaining a straight pull on the limb. A boot appliance is applied to attach to the traction); Bryant’s (a vertical traction used to extend both lower legs used in children to stabilize a fractured femur and at times used to correct a congenital hip dislocation; rarely used); Russel traction is a balanced traction which lower leg is supported in a hammock which is attached to rope and pulleys on a Balkan frame; used to treat fractures of femur, foot of bed usually elevated. Pelvic traction is used to relieve low back, hip or leg pain and reduce muscle spasms and Dunlop’s traction a horizontal traction to align fractures of the humerus, it maintains the forearm in proper alignment
What are some traction care tips we need to follow?
Ensure that ropes and weights hang freely and do not touch floor and pulleys are not obstructed. Keep linen off ropes. Do not remove or lift weights without an order
Teach deep breathing and coughing exercises
Exercise unaffected limbs to maintain muscle tone and prevent bone demineralization
Encourage 2500/ml per day if not contraindicated to prevent constipation, UTI, and renal calculi
With bucks traction assess skin under foam boot every shift (second person hold traction during removal)
What is Exogen therapy?
low intensity pulsed ultrasound and is Applied 20 minutes daily to speed healing
What is Iontophoresis?
a synthetic steroid that is placed into skin near fracture to assist with control of pain and inflammation
What microbe causes gas gangrene most?
Clostridium perfringens
What are some symptoms for gas gangrene?
Local swelling and a serosanguineous exudate
Bronze skin color, that progresses to a blue-black color with skin blebs and hemorrhagic bullae.
The wound may be nonodorous or may have a sweet musty odor.
Crepitus follows gas production; at times, crepitus may not be detected with palpation or on x-ray.
Management Includes:
Requires debridement and possible amputation.
Penicillin type IV antibiotics
IV pain management
Hyperbaric oxygen
What is compartment syndrome?
the compression of nerves and blood vessels within an enclosed space. Diagnosis requires direct measurement of pressure in the compartment. (Done by inserting a needle attached to a pressure meter into the affected area). Diagnosis is made if the pressure is greater than 45 mmHg or when the pressure is within 30 mmHg of the diastolic blood pressure.
Should we elevate an extremity with compartment syndrome?
Limbs with compartments showing signs of inadequate blood flow should not be elevated. the arteriovenous gradient will be further diminished when blood flow is already inadequate.
What is the name of a fracture related to osteoporosis in the elderly?
Calles fracture
Should we sit patients up after a lower extremity fracture?
Avoid sitting at 90 degrees as it may cause dislocation
How should we transport an amputated finger?
it is important the finger be wrapped in gauze or cloth, the placed in a zip lock bag, placing the bag in ice water (never place the finger directly in ice)
What is Syme amputation?
midfoot or below ankle amputation
What med is given to prevent phantom pain?
Calcitonin
