Flashcards in Musculoskeletal Disorders Deck (69):
Form of electromagnetic radiation.
Nuclear scanning test that identifies new areas of bone growth or breakdown.
Creates a 3-D image from multiple X-rays images.
Computed Tomography Scan (CT)
Measure the electrical impulses of muscles at rest and during contraction.
Allows analysis of fluid for signs of inflammation, bleeding, and infection.
Synovial Fluid Aspiration
Uses strong magnetic field. No radiation. Patients with some types of metal implants can not have.
Minimally invase surgical prodecure in which an examination and sometimes treats of damage of the interior of a joint is performed.
Elevated in many muscle diseases.
Serum Creatine Kinase (SCK).
Results when the skin is broken.
Skin is not broken at the fracture site.
A bone is broken to form two or more separate pieces.
Bone is only partially broken.
Single break in the bone in which the bone ends maintain their alignment and position.
The are multiple fracture lines and bone fragments.
When a bone is crushed or collapses into small pieces.
When one end of the bone is forced into the adjacent bone.
Result from a weakness in the bone structure. Example - during cancer.
Fracture result from repeated excess stress.
Occur in the skull when the broken section is forced inward on the brain.
Fracture across the bone.
A break along the axis of bone.
Fracture at an angle to the diaphysis.
Fracture that angles around the bone.
Fracture at the distal radius at the wrist.
Fracture of the lower fibula due to excessive stress on the ankle.
Fracture of the 5th metatarsal.
Forms in the medullary canal, under the periosteum, and between the ends of the bone fragments.
Form new cartilage.
The bone ends become splinted together by a _______.
Generate new bone.
Amount of local damage to bone and soft tissue, amount of realignment and approximation, secondary problem, and numbers systemic factors.
Factors Affecting Healing Process
Due to local pain and irritation.
Such as tetanus, osteomyelitis. Precautions include antibiotics.
Occurs as edema increases in 1st 48 hours after trauma and casting.
Grating sound heard, if the ends of bone fragments move over each other.
Increased pressure of fluid within fascia, the nonelastic covering of muscles. Usually lower leg.
Can occur with severe trauma or tearing of periosteum.
Requires surgery, plates & pins.
Open Reduction Internal Fixation (ORIF)
Cast, splints, and traction.
Application of forces or weight pulling on limb that is opposed by body weight.
Separation of two bones at a joint with loss of contact between the articulating bone surfaces.
If bone is only partially displaced.
Tear in ligament.
Tear in a tendon/muscle.
Ligaments or tendons completely separated from their bony attachment.
Common metabolic bone disorder. Decreased bone mass and density. More common in women.
Postmenopausal, senile, and idopathic.
Following specific primary disorder (Cushing's syndrome).
Result from deficit of vitamin D and phosphates.
Rickets & Osteomalacia
Bow legs, in children.
Soft bones and compression fractures, in adults.
Progressive bone disease that occurs in adults older than 40 years.
Majority of primary bone tumors are _____.
Malignant neoplasm that usually develops in the metaphasis of the femur, tibia, or fibula in children/young adults.
Malignant neoplasm common in adolescents that occurs in the diaphysis of long bones.
Group of inherited disorders characterized by degeneration of skeletal muscle.
Most common type of muscular dystrophy is?
Duchenne's Muscular Dystrophy
Group of disorders characterized by pain and stiffness affecting muscles, tendons, and surrounding soft tissue. Higher in women 20-50 years old.
Wear and tear arthritis.
Auto-immune disease, causing chronic systemic inflammatory disease.
Rheumatoid Arthritis (RA)
Inflammation recurs, synovial cells proliferate.
Granulation tissue from synovium spreads over articular capsule.
Eroded by enzymes from panes, panes also cuts off nutrients.
Panes between bone ends becomes fibrotic, limits movement.
Joint fixation and deformity.
Results from deposits of uric acid and rate crystals in the joint. Most common in men older than 40 years old.
Develops in a single joint.
Infections (Septic) Arthritis
