Q
  • A break in bone at the base of the skull.
  • very difficult to demonstrate radiographically
  • air-fluid levels in the sphenoid sinus and/or clouding of the mastoid air cells are often the only radiographic finding suggesting a fracture
  • important to include erect or cross-table lateral skull radiography
  • CT and MRI are often used to better identify fractures and associated soft tissue damage within the skull

Q
  • refers to a separation of the body of the maxilla from the base of the skull above the palate and below the zygomatic process

Q
  • results from a direct blow to the front of the orbit, thus transferring the force to the orbital walls and floor
  • occurs in the thinnest, weakest portion of the orbit, i.e., the orbital floor just above the maxillary sinuses
  • modified parietoacanthial projection (modified Waters method) is the preferred screening study
  • CT is the best modality for imaging the orbits

Q

  • occurs when the zygomatic or malar bone is fractured at all three suture: frontal, temporal, and maxillary

16
Q
  • results when a bone is out of its joint and not in contact with its normal articulation
  • Common sites for are the shoulders, hip, and acromioclavicular joints
A

JOINT DISLOCATION OR LUXATION

17
Q

most frequently dislocated joint of the body. Because it moves in several directions, your ____ can dislocate forward, backward or downward. The most common variety is a forward (anterior) dislocation.

A

Shoulder dislocation

18
Q

dislocation is described by which joint is affected and by the direction of the phalanx distal to the joint relative to the phalanx proximal to the dislocated joint (eg, dorsal dislocation at the PIPJ). It is important to assess for any associated fractures pre- and post-reduction:

A

Dislocations to the interphalangeal joints

19
Q
  • a partial dislocation, often occurring with fracture
  • ankle and the vertebral column are the common sites of ___
A

SUBLUXATION

20
Q
  • also referred to as nonaccidental trauma (NAT)
  • term associated with a physical form of child abuse
  • Physical child abuse often co exists with both emotional and sexual abuse
  • Physical signs include bruises, burns, abrasions, and fractures in various stages of healing
  • Radiographic signs of child abuse include hematomas, and single or multiple fractures of varying ages, especially in areas where it is difficult for the child to self-inflict the injury
A

BATTERED CHILD SYNDROME

21
Q
  • common form of avascular necrosis affecting the femoral head
  • the cause of this disorder is unknown
  • tends to occur in males between the ages of 4 to 10 years and often follows injury or trauma to the affected hip
  • clinically these patients present with a limp that is accompanied by little or no pain
  • Radiographically the bone in the center of the epiphysis is fragmented and the head of the femur is flattened.
A

LEGG-CALVE-PERTHES DISEASE

22
Q

causes of ____ injuries include direct trauma, hyperextension-flexion injuries (whiplash), osteoporosis or metastatic destruction.

A

VERTEBRAL COLUMN INJURIES

23
Q
  • most frequent type of injury involving a vertebral body
  • generally occur in the thoracic and lumbar vertebrae
  • also associated with osteoporosis
A

COMPRESSION FRACTURES

24
Q
  • “burst fracture” of the first cervical vertebra (atlas)
  • generally occurs as a result of a severe axial force that causes compression, as in a diving accident
  • vertebral arch literally bursts
A

JEFFERSON FRACTURE

25
Q
  • fracture of the arch of the second cervical vertebrae and is usually accompanied by anterior subluxation of the second cervical vertebrae or the third cervical vertebrae
  • c2-c3
A

HANGMAN’S FRACTURE

26
Q
  • an avulsion fracture of a spinous process in the lower cervical or upper thoracic spine
A

CLAY SHOVELER FRACTURE

27
Q
  • exists when there is a cleft or breaking down, of the body of a vertebra between the superior and inferior articular processes (pars interarticularis).
  • occurs in the arch of the fifth lumbar vertebrae and appears radiographically as a “collar” or “broken neck” on the Scottie dog appearance and is demonstrated on an oblique projection of the lumbar spine.
A

SPONDYLOLYSIS

28
Q
  • forward slippage of the vertebral column off a vertebra that occurs because of spondylolysis
  • patient with this condition may present symptoms identical to those of a herniated disk
A
