TRAUMAFractures, Dislocations & other injuries
By Barbara Peacock
Cumberland County College
Deformity of a limb
Clinical indication of dislocation
A/A or MVA
Closed vs compound fractures
ANOTHER OUCH !
(also an oblique fx because of the direction of the fracture line)
Fracture line rotates around the bone, usually from a twisting force
2 or more fracture lines = 3 or more fragments
Severe communited !
Typical of a front seat
passenger in a car
Fractured ends get pushed into one another
Fracture ends are thin shards or splinters like wood.
Specific to the patella-
fracture lines radiate out from a center point in a star-like pattern.
Specific to the vertebrae - vertebral body collapses, anterior aspect is reduced in height.
From trauma or demineralization of bone (old age).
C1 ring is broken, fragments move outward.
Football injuries, heavy object dropped on head.
C - 1 (atlas)
Orbital floor collapses from direct blow to eyeball
Section of bone pushed into center of an area
Fractured bone causes damage to an internal organ. Ex. - rib pierces lung
Caused by stress to a joint, ligament, or tendon. Small piece of bone is torn away. Often seen with dislocations.(see note)
1. Pathologic - bone is weakened by disease, spontaneous fx’s
(cancer, osteomalacia, osteomyelitis, Pagets)
2. Stress - caused by prolonged running or marching - metatarsals fracture. Difficult to visualize.
1. Greenstick (torus) - incomplete fx, bones more flexible, bends & fractures only outer edge.
2. Epiphyseal - fractures located at the site of an epiphysis. Sometimes with associated dislocation (slipped epiphysis)
Don’t forget to review the specific fracture types listed on the last pages of your handout! (eg: Colles, nursemaid, Potts)
