1.2 Chapter 9: PART II Mechanisms and Characteristics of Musculoskeletal and Nerve Trauma Flashcards
Bone review
How are Bone Fractures classified? What are sympotoms?
Classified as either closed or open;
CLOSED– fractures are those where there is little movement or displacement
(X-rays are nesseary for diagnosis)
OPEN—Fractures break the skin
sympotoms: Deformity; pain; point tenderness; swelling; painful active and passive movements
Types of causes of fractures:
Direct— at force application
Indirect—internal injury (usally from bones)
Types of Fractures?
Greenstick,
Comminuted,
Linear,
Transverse,
Oblique,
Spiral,
Impacted
Transverse Fracture.
How do they occur?
Result?
Transverse—broken bone where the break is at a right angle to the long plane of the bone.
(Broken horizontaly)
most often occur as the result of a strong force applied perpendicular to the long axis of a bone.
result of a stress fracture where many microscopic
breaks form in the bone from repetitive stress, such as running
Oblique and Spiral. How to fix?
triangular fraction, by torsional forces.
Oblique— like a transvere fracture but 30 degree not horizontal
Spiral—Like a corkscrew. Create a fracture line that wraps around your bone. twisted with great force
Greenstick Fracture. Cause?
crack or break on one side on a long bone. breaks splinteringly like a fresh green stick.
Incomplete Fracture
Often in children.
Cause: Forcful impact from blow or twist.
Linear Fracture
Linear Fracture—A fracture that occurs parallel to the long axis of the bone.
(Common in skull)
Avulsion Fracture
When a ligament pull a peice of bone away.
Blow out Fracture
Serrated fracture
Depressed Fracture
Contrecoup Fracture
What are the only motions occur at the Talocrural joint?
dorsi/plantar flexion
What motions happne at the subtalar joint?
Eversion/inversion
