Trauma Flashcards
Define trauma
Abnormal force applied to body resulting in injury
More traumatic injuries are cause by ___ energy injuries
Low energy
Define fracture
A break in the continuity of bone surface
Define comminution
Bone fragmented
Define intra articular
Bone fracture on articulating surface
Eg: elbow/ knee fracture
Open fracture vs closed fracture
Bone through skin
Bone within skin
Cause of fracture
Normal bone+
Abnormal bone+
Normal bone + and increased___
Normal bone + abnormal force
Abnormal+ normal force
Normal bone+ abnormal force and ^ trauma risk
Three types of complete fractures
Oblique
Transverse
Spiral
Primary healing of a fracture
Fully immobilized
Direct healing with no fracture callous
Skips secondary healing goes to remodeling
Secondary healing
Little movement
Inflammation
Healing
Repair
Two differences between primary and secondary healing
Primary- no movement Haversian canal forms in bone
Secondary- partial immobilization
4 R’s of fracture
Resuscitate
Reduce- joints back in place
Restrict- limit movement
Rehabilitate
Two disadvantages of operative management of fractures
Not full control of fracture
Invasive
Joint stiffness
Advantages of non operative management of fractures
Simple splints are cheap easy and non invasive
3 features of high energy trauma
Soft tissue injuries
Fracture displacement
Complex fractures
