Musculoskeletal system Flashcards
Risk factors accosicated with Musculoskeletal disorders
- Autoimmune disorders
- Calcium deficiency
- Falls
- Hyperuricemia
- Infection
- Medications
- Metabolic disorders
- Obesity
- Postmenopausal status
- Trauma & injury
Athrocentesis
Used to diagnose joint inflammation and infection. Done by aspirating synovial fluid, blood or pus via a needle inserted into the joint cavity.
Arthrography
Radiographic examination of the soft tissue of the joint structures. Used to diagnose trauma to the joint capsule or ligaments. Contrast dye is injected into joint followed by an x-ray.
Arthroscopy
Endoscopic joint exam used to diagnose and treat acute disorders of the joint.
Dual X-Ray Absorptiometry
Measures bone mass of the spine, wrist, hip and total body. Used to diagnose metabolic some disease and monitor bone density changes.
Bone Scan
Used to identify, evaluate and stage bone cancer and used to detect fractures. Radioisotope is injected and collects in areas of abnormal bone metabolism and fractures.
Electromyography (EMG)
Measures electrical potential of skeletal muscle contractions by inserting needles into muscle and activity is recorded on an oscilloscope. Used to evaluate muscle weakness.
Sprains are treated with…
R - Rest
I - Ice
C - Compression
E - Elevation
Closed/Simple fracture
Skin over the fracture is in intact
Comminuted fracture
Bone is splintered or crushed
Complete fracture
Bone broken into two parts
Depressed fracture
Bone fragments are driven inward
Greenstick fracture
One side of the bone is broken the other is bent
Impacted fracture
Part of the fractured bone is driven into another bone.
Incomplete fracture
Fracture does not go all the way through the bone
Oblique fracture
Fracture runs at an angle across the bone
Open/compound fracture
Bone exposed to the air increasing the risk of infection and soft tissue injury.
Pathological fracture
Fracture caused by weakening of the bone structure by a pathological process such as neoplasia.
Neoplasia
Abnormal growth of new tissue
Transverse fracture
Bone fractured straight across
Closed reduction
Manual manipulation of a bone fracture to restore bone alignment
Open reduction
Surgical intervention to realign bone fracture.
Fixation
Insertion of screws, pins or plates to repair damaged bone. May include removal of parts of bone and immediate stabilization.
Skeletal traction
Applied mechanically to the bone with pins, wires or tongs. Typical weight is 25-40 lbs.
Skin traction
Applied using elastic bandages or adhesive, foam boot or a sling.
Dunlop’s traction
Horizontal traction used to align fractures of the humerus. Vertical traction maintains proper alignment.
Isometric exercises
Prevent muscle atrophy
Monitor a casted extremity for…
- Pain
- Swelling
- Discoloration
- Tingling
- Numbness
- Coolness
- Diminished pulses
Fat embolism
Complication of fracture. Originates in the bone marrow and occurs after a fracture when a fat globule is released into the bloodstream. Usually occurs in a long bone.
