Gutter fracture is due to –
**Core Concept**
Gutter fracture refers to a specific type of fracture that occurs in the skull, typically caused by a severe impact. This type of fracture is characterized by a depression of the inner table of the skull, often resulting from a tangential or glancing blow.
**Why the Correct Answer is Right**
A gutter fracture occurs when a force is applied tangentially to the skull, causing a depression of the inner table. This type of fracture is often seen in cases of assault or trauma where the force is applied at a 90-degree angle to the skull. The mechanism of injury involves the transmission of force through the outer table of the skull, resulting in a depression of the inner table.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect as gutter fracture is not typically associated with rotational forces.
**Option B:** This option is incorrect as gutter fracture is not typically associated with axial loading.
**Option C:** This option is incorrect as gutter fracture is not typically associated with a direct blow to the skull.
**Clinical Pearl / High-Yield Fact**
It is essential to note that gutter fractures can be a sign of non-accidental trauma, especially in infants and children. A high index of suspicion is necessary to diagnose and manage such cases.
**Correct Answer:** D.
