Q

Avulsion Fx

A

Tearing away of a part: a fragmentation of bone where the pull of a strong ligamentous or tendinous attachment tends to forcibly pull the fragment away from the rest of the bone.

25
Q

Bursting Fx

A

multiple fragments, usually at the end of a bone: classically, Fx of the 1st cervical vertebra

26
Q

Butterfly Fx

A

a bone fragment shaped like a butterfly and part of a comminuted: usually involes high energy force delivered to the bone

27
Q

Chip Fx

A

small fragment, ussally at the articular margin of a joint.

28
Q

Comminuted Fx

A

(Splintered Fx) More than two fragments: lines of fz may be transverse, oblique, spiral, or T or Y shaped:

29
Q

Complete Fx.

A

the bone is completely broken through both cortices.

30
Q

Compression Fx

A

Crumbling or smashing of cancellous bone by forces acting paralled to the nong axis of bone: applied particularly to the vertebral body fx

31
Q

Depressed Fx

A

Typically an intra-articukar depression of fragments, but may also be applied to depressed skull fx

32
Q

Double Fx

A

segmental fx of a bone in two places

33
Q

Epiphuseal Fx

A

Involves the portion of the bone tgat distal to the physis, which is the growth plate

34
Q

Fissure Fx

A

crack on the outer layer in one cortex usually long bone

35
Q

Greenstick Fx

A

Incomplete , interperiosteal, hickory-stick , willow FX= In children, incomplete, angulated fx w/ partial break

36
Q

Hairline Fx

A

nondisplaced fx line in the cortex

37
Q

Impacted Fx

A

Fragments are compressed by force of original injury, driving one fragment of bone into adjacent bone.

38
Q

Incomplete Fx

A

Greenstick, torus Fx. Cortices of bone are buckled or cracked, but continuity is not destroyed: the cortex is broken on one side and only bent on the other.

39
Q

Infraction Fx.

A

a neoplastic fracture characterized by a small radiolucent line in radiographs in pathologic fx, most commomly resulting from metabolic problems

40
Q

insufficiency Fx

A

a fx that occurs due to bone that is made insuffucient due to osteoporosis or a metabolic procces

41
Q

Linear Fx

A

lengthwise fx of bone straight line fx, implies that there is no displacement

42
Q

multiple fx,

A

Two or more spearate lines of fx in the same bone.

43
Q

Oblique Fx

A

slanted fx of the sahft on long axis of bone.

44
Q

occult fx

A

hidden fx, generally occurring in areas of the ribs, tiba, metatarsls, and navicula.

45
Q

Physeal Fx.

A

Epiphyseal slip fx Salter-Harris Fx, ,One that involves the cartilaginous growth plate of a bone,

46
Q

Plastic bowing Fx.

A

Greenstick fx, bowing fxcurved deformity of a tubular bone w/out gross fx

47
Q

Secondary Fx

A

pathological fx of bone weakend by disease

48
Q

Segmental Fx

A

several lg fx in the same bone shaft where the two principal fragments are not adjacent

49
Q

Spiral Fx

A

Fx line is spiral shaped, usually on the shaft of long bones where the mechanism of injury is usually torsion.

50
Q

Stellate Fx

A

numerous fissures radiate from central point of injury.

51
Q

Subperiosteal Fx

A

bone but not its periosteal tube is broken: uncommon, usually the result of a direct blow

52
Q

Torus Fx.

A

usually noticed in children: a stable, often incomplete fx in which one distal cortical surface appears to be wrinkled by compression forces, and the opposite cortex may or may not be infracted by tension forces.

53
Q

Transverse Fx

A

Line of fx across the shaft at right angles to the long axis of a bone

54
Q

Unstable Fx

A

Fx that most often requires operative intervention due to the likelihood of recurrent deformity despite manipulation

55
Q

Position of fragments

A

refers to any displacement of one bone fragment in reference to the next.

56
Q

Alignment of fragments

A

refers to raotatory and/or angular deviation of the distal fragment in relation to the proximal fragment

57
Q

Bayonet position

A

The fragments touch and overlap, but there is good alignment. Internal and external rotation can also be stated in degrees.

58
Q

Bow

A

the two fragments form an angle where the apex is sometimes described as an anterior or posterior bow.

59
Q

Angulation

A

the direction of the apex of the fx point.
