Rad Pathology Ch 4

Skeletal System

When a vertebra has the characteristic of more than one major subdivision of the spine: Transitional Vertebra
Spina Bifida with meningeal protrusions, herniation of the meninges in the lumbar or cervical spines Meningocele
A rare hereditary bone dysplasia involving the bone resorption mechanism of calcified cartilage. Osteopetrosis
An inherited disorder of connective tissue characterized by multiple fractures and bone abnormalities: Osteogenesis Imperfecta
Another name for Osteogenesis Imperfecta: Brittle Bone Disease
Most common form of dwarfism that results from diminished proliferation of cartilage in the growth place (Enchondral bone formation) Achondroplasia
This begins as an inflammation of the synovial membrane causing synovial proliferation: Rheumatoid Arthritis
What is the prevalence of Rheumatoid Arthritis? Women affected 3 times more than men & onset is 40 years old
A chronic systemic disease of unknown cause: Rheumatoid Arthritis
The most common form of degenerative arthritis that has osteophyte development: Osteoarthritis
Define Osteophyte: Bony outgrowth (bone spur)
The result of a pyogenic organism entering the joint through the blood, direct extension, or trauma: Infectious Arthritis
This begins as an abscess of the bone where pus produced by acute inflammation spreads down the medullary cavity and outward to the surface: Osteomyelytis
How can Osteomyelytis be seen? When the infection reaches the outer margin of the bone it raises the periosteum of the bone and can spread considerably.
This is caused by accelerated bone resorption and will cause a loss of bone density: Osteoporosis
The breakdown of bone by osteoclasts: Bone Resorption
What are the most common causes of Osteomyelytis? Staphylococcus and Streptococcus
The insufficient mineralization of the adult skeleton appearing as a loss of bone density: Osteomalacia
How will Osteomalacia appear? The body weight on weight-bearing long bones may bend or bow as a result of softened bone.
Blood levels with increased uric acid leading to deposits of crystals in the joints, cartilage and kidney: Gout
What is the beginning phase of Paget's Disease? Involves Bone Destruction
A proliferation (too much) of fibrous tissue in the medullary cavity. Fibrous Dysplasia
When does Fibrous Dysplasia normally begin? During childhood
This results from a loss of blood supply where a pattern of lytic and sclerotic new bone growth appears with a flattening of the femoral head associated with periosteal new bone. Ischemic Necrosis
The appearance of this is expansible, eccentric cyst like lesions that causes marked ballooning of the thinned cortex and having internal septations. Aneurismal Bone Cyst
A classic sunburst pattern of bony spicules that extend in a radiating fashion: Osteogenic Sarcoma
Primary malignant tumors arising from the bone marrow of long bones in children and young adults usually causing localized pain: Ewing Sarcoma
Classic radiographic appearance of multiple punched-out osteolytic lesions scattered throughout the skeletal system: Multiple Myeloma
What specifically will multiple myeloma look like? Swiss cheese
What does an incomplete fracture look like? A crack in the bone that does not go all the way through.
What does a transverse fracture look like? A break in the bone that goes all the way across perpendicular to the bone.
What does an oblique fracture resemble? A straight diagonal fracture through the bone
What does a spiral fracture resemble? A fracture that curves around the length of the bone.
What does a comminuted fracture resemble? Complete spidery fractures
What does an avulsion fracture resemble? A break at the end of the bone where a piece of the bone is broken off at the articulating end.
What does a butterfly fracture resemble? A triangular part of the bone is broken out. (Butterfly wing)
What does a segmental break resemble? Just like it sounds (sort of looks like bone shortening)
What does a Greenstick fracture resemble? A break along the bending portion of a bone
What does a Torus fracture resemble? Doesn't resemble a fracture at all, it looks like a bulging of the bone on both sides.
Posterior displacement of the distal fragment of the radius usually caused by falling on an outstretched hand. Colle's Fracture
A fracture of the bone due to a weakened bone caused by a tumor or infection is known as a ______________ _________. Pathologic Fracture
This is healing of fracture fragments in faulty or poor position and usually leads to impairment of normal function: Malunion
What is another term for "Battered Child Syndrome"? Suspected Nonaccidental Trauma
Forward displacement of one vertebra over another resulting in back pain: Spondylolisthesis
What causes Spondylolisthesis? A cleft in the pars interarticularis
What is the defect that occurs with Achondroplasia? As it's stated means diminished formation of cartilage but it's actually that cartilage is not being converted to bone properly especially in the long bones.
Meningocele occurs in what portion of the spine? Cervical or lumbar
(abnormal increase in bone density) Osteopetrosis
