Question

A man presents with back pain following a road traffic accident. There was no history of neurological deficit. X-ray spine is done. What is the diagnosis? 

• A. Spinous process fracture
• B. Chance fracture
• C. Fracture o base of vertebrae
• D. Compressed fracture

Hint:

For isolated back pain without neurological deficits following trauma, consider a spinous process fracture. This injury is often less severe than other spinal fractures.

Answer 1

The Correct Option is A

Solution:

In the context of a patient presenting with back pain following a road traffic accident and no neurological deficits, the key steps in identifying the correct diagnosis from an X-ray involve recognizing characteristic patterns associated with different types of fractures. Let's break down the options:

• Spinous Process Fracture: This type of fracture specifically involves a crack or break in the spinous process, which is the bony protrusion on the posterior aspect of a vertebra. It is often caused by direct trauma or sudden forceful flexion or extension of the spine.
• Chance Fracture: This is a horizontal fracture through the spinal vertebra, often involving the vertebral body, pedicles, and spinous process. It is usually associated with flexion-distraction injuries, often seen in high-speed accidents where seat belts provide an abrupt halting force.
• Fracture of Base of Vertebrae: This indicates a break at the base of the vertebra, involving substantial structural components and would likely present with some neurological deficit depending on the extent.
• Compressed Fracture: These involve the collapse of a vertebral body, often seen in conditions like osteoporosis, or due to axial loading trauma. They might cause anterior wedge shape in vertebrae but may not directly account for isolated spinous process involvement.

The absence of neurological deficits in the described scenario is particularly important. A spinous process fracture generally does not lead to neurological dysfunction because it does not impinge on the spinal cord or nerve roots. The image provided in the question likely displays the bony projections of the spinous part to assist in confirming this diagnosis.

Therefore, considering the information, the most accurate diagnosis is a Spinous Process Fracture.
