What are the symptoms of a spinal fracture?
- Sudden onset, severe pain, relieved by lying down.
- History of trauma (this may be minor in those with osteoporosis)
- Structural spinal deformity
- Point tenderness over a vertebral body
What are 4 serious differentials you must rule out when considering back pain?
- Cauda Equina
- Spinal fracture
- Cancer (cord compression)
- Infection
What is the difference between spondylosis, spondylitis, spondylysis, and spondylolesthesis?
SPONDY = spine
SpondyLOSIS = degenerative
SpondyLITIS = Inflammatory, this can be due to anything that results in inflammation.
SpondyloLYSIS = “break down” of a bone typically a stress fracture of the Pars Interarticularis, classically seen as a Scottie dog fracture on an X-ray.
SpondyloLESTHESIS = (to slip) – Slippage of a vertebrae body (not disc) typically due to a Pars Interarticularis fracture, but can also happen in degenerative conditions. This can cause nerve root compression.
What is the “rescue dose” of morphine for breakthrough pain?
Between 1 /10th and 1 /6th of the regular 24 hour dose (take every 2-4 hours unless severe / last days)

8g in one unit, takes 1 hour
What is the difference between HDL and LDL?
HDL is known as “good cholesterol” It carries cholesterol away, from the blood vessel wall, back to the liver. The higher it is the more cholesterol comes off the blood vessels.
LDL on the other hand goes the other way, from the liver to the blood vessels to cause atheromatous plaques.
