|
|
Term
| A fx that runs at a right angle to the long axis of a bone and most commonly results from a direct blow or is a fx within pathologic bone: |
|
Definition
|
|
Term
| A fx that runs a course of approximately 45 degrees to the long axis of the bone and is caused by angulation or by both angulation and compression forces: |
|
Definition
|
|
Term
| A fx that encircles the shaft of the bone and is generally longer than an oblique fx; it is caused by torsional forces: |
|
Definition
|
|
Term
| Fxs in which generally small fragments are torn from bony prominences; they are usually the result of indirectly applied tension forces within attached ligaments and tendons rather than direct blows: |
|
Definition
|
|
Term
| A fx that is composed of more than two fragments: |
|
Definition
|
|
Term
| A ________ fragment is an elongated triangular fragment of cortical bone generally detached from two other larger fragments of bone. |
|
Definition
|
|
Term
| A fx that consists of a segment of the shaft that is isolated by proximal and distal lines of fx: |
|
Definition
|
|
Term
| A fx that results from a compression force that causes compaction of bone trabeculae and results in decreased length or width of a portion of a bone: |
|
Definition
|
|
Term
| A fx that occurs in the skull or tibial plateau; characterized by portions of the fracture fragments driven inward: |
|
Definition
|
|
Term
| A _____ or _____ fx is the response of bone to repeated stresses, none of which is sufficient to cause a fx: |
|
Definition
|
|
Term
| A fx that occurs in bone at an area of weakness caused by a process such as tumor, infection, or metabolic bone disease: |
|
Definition
|
|
Term
| A fx that is incomplete with the opposite cortex still intact; this type of fx is very common in infants and children because of the softness of their cancellous bone: |
|
Definition
|
|
Term
| A fx in which one cortex is intact with buckling or compaction of the opposite cortex: |
|
Definition
|
|
Term
| A _______ fx is a plastic deformation caused by a stress that is too great to permit a complete recovery of normal shape but is less than the stress required to produce a fracture: |
|
Definition
|
|
Term
| A fx in which a plane of cleavage exists in the bone without angulation or separation: |
|
Definition
|
|
Term
| A transverse fx through the distal radius with dorsal (posterior) angulation and often overriding of the distal fx fragment: |
|
Definition
|
|
Term
| A transverse fx of the neck of the fifth metacarpal with volar (palmar) angulation of the distal fragment; it is often typically the result of a blow struck w/ the fist: |
|
Definition
|
|
Term
| An isolated fx of the shaft of the ulna associated w/ anterior dislocation of the radius at the elbow: |
|
Definition
|
|
Term
| Is a combination of a fx of the shaft of the radius and a dorsal (posterior) dislocation of the ulna at the wrist: |
|
Definition
|
|
Term
| A transverse fx at the base of the 5th metatarsal: |
|
Definition
|
|
Term
| A comminuted fx of the ring of the atlas, involves both the anterior and posterior arches and causes displacement of the fragments: |
|
Definition
|
|
Term
| This fx is the result of acute hyperextension of the head on the neck. It appears as a fx of the arch of C2 anterior to the inferior facet and is usually associated with anterior subluxation of C2 on C3: |
|
Definition
|
|
Term
| Is an avulsion fx of a spinous process in the lower cervical or upper thoracic spine: |
|
Definition
|
|
Term
| A transverse fx of a lumbar vertebra that is often associated w/ significant visceral injuries: |

Definition
|
|
Term
| Fxs of the zygomatic arch and the orbital floor or rim combined w/ separation of the zygomaticofrontal suture: |
|
Definition
|
|
Term
| How is a zygomatic arch fx best demonstrated? |
|
Definition
| Zygomatic arch fxs are best demonstrated on underexposed films taken in the basal (submentovertex) projection ("jug handle" view) |
|
|
Term
| A linear fx that intersects a suture and courses along it to cause sutural separation: |
|
