1. Trauma and Overuse: Fracture Vocab Flashcards
Fracture resulting from the mismatch of bone strength and chronic mechanical force.
Stress Fracture
Abnormal stress on Normal Bone.
Fatigue Fracture
Insane (but kinda hot) Type A Female Cross Country Runner - literally runs until her legs & feet break in half
Fatigue Fracture
Old lady with horrible osteoporosis breaks her back (compression fracture) by walking down a few steps. She blames Obama for the fracture.
Insufficiency Fracture
Normal stress on Abnormal bone.
Insufficiency Fracture
a fracture through a Ivtic bone lesion.
Pathologic Fracture
A fracture associated with an open wound.
Open Fracture {Compound Fracture)
3 phases of fracture healing
Inflammatory
Reparative
Remodeling
Granulation tissue will be forming between the bone fragments in how many days?
7-14 days
increased lucency of the fracture site related to bone resorption.
a healing fracture will be MORE LUCENT at ___ days
7-14 days
In general, bones heal in about __ weeks
6-8 weeks
Healing
is the fastest in =
slowest =
fracture not healed within the expected time period (but still might). Some sources will say “twice as long as expected”
Delayed Union
fracture is not going to heal without intervention. Some sources will say “6-9 months.” The classic locations are the scaphoid, anterior tibia, and lateral femoral neck.
Non-Union
This is union in poor anatomic position (healed crooked as a politician).
Mal-Union
Vitamin D plays a vital role in
calcium uptake and metabolism.
altered calcium absorption (causes secondary hyperparathyroid and stripping of calcium from bones) and therefore higher rates of non union.
Gastric Bypass
This is the most common site ofa stressfracture in young athletes.
Tibial Stress Fracture
Fractures of the Compressive side are constantly
pushed back together
Fractures of the Tensile side are constantly
pulled apart
Scenario
Old lady + sudden pain after rising from seated posision =
SONK (Spontaneous Osteonecrosis of the Knee)
It’s an insufficiency fracture
Think SINK not SONK
the most fractured tarsal bone.
Calcaneus
the navicular is high risk for
AVN
High Risk vs Low Risk Stress Fractures:
