Spinal compression can lead to which of the following types of fractures?

• A. Concave and burst fractures
• B. Compression and avulsion fractures
• C. Wedge and spinous process fractures
• D. Transverse and oblique fractures

Answer: (A)

Spinal compression typically occurs when there is excessive force applied to the vertebrae, leading to specific types of fractures associated with the mechanics of compression. Concave fractures occur when a loading force compresses the vertebra, leading the bone to buckle inward, while burst fractures result from significant axial loads that cause the vertebra to shatter or fracture in multiple places. Both types of fractures are characteristic of spinal compression injuries, making the response accurate.

The other types of fractures listed in the choices each relate to different mechanisms or locations within the spinal anatomy. For instance, avulsion fractures involve the tensile force pulling away fragments from bony attachments, which is not solely associated with compression. Wedge fractures, while they can occur with some degree of compression, primarily characterize the anterior part of the vertebra collapsing, which is different in mechanism than the more severe burst fractures. Transverse and oblique fractures relate to specific angles of force that indicate bending or torsional stress instead of pure compression forces. Understanding the mechanics of spinal injuries highlights why concave and burst fractures align with the nature of spinal compression.
