Fractures Flashcards
What is a compound fracture
the skin is broken and the broken bone is exposed to the air. The broken bone can puncture through the skin.
What is a stable fracture
refers to when the sections of bone remain in alignment at the fracture
What does a comminuted fracture refer to
Breaking into multiple fragments
What is a colle’s fracture
transverse fracture of the distal radius near the wrist, causing the distal portion to displace posteriorly (upwards), causing a “dinner fork deformity”. This is usually the result of a fall onto an outstretched hand (FOOSH)
What type of fracture can a FOOSH result in
Scaphoid fracture
Key signs of scaphoid fracture
tenderness in the anatomical snuffbox (the groove between the tendons when extending the thumb).
Complications of scaphoid fracture
scaphoid has a retrograde blood supply, with blood vessels supplying the bone from only one direction.
This means a fracture can cut off the blood supply, resulting in avascular necrosis and non-union.
What do ankle fractures tend to involve
lateral malleolus (distal fibula) or the medial malleolus (distal tibia)
Classification used for ankle fractures
Weber classification
What is important for stability and function of ankle joint
tibiofibular syndesmosis
Main cancers that metastasise to the bones
Po – Prostate R – Renal Ta – Thyroid B – Breast Le – Lung
Guidelines used to guide medical treatments for fragility fractures
NOGG guidelines
How can fractures be mechanically re-aligned
Closed reduction via manipulation of the limb
Open reduction via surgery
What is a fat embolism
Fat embolism can occur following the fracture of long bones (e.g., femur). Fat globules are released into the circulation following a fracture (possibly from the bone marrow).
These globules may become lodged in blood vessels (e.g., pulmonary arteries) and cause blood flow obstruction.
Presentation of a fat embolism
Gurd’s major criteria:
Respiratory distress
Petechial rash
Cerebral involvement
