Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: A signature fracture is a type of depressed skull fracture.
Step 2: It occurs when a heavy object with a small striking surface, such as a hammer or the end of a rod, strikes the head with force concentrated over a small area.
Step 3: The bone is driven inwards and the resulting depressed fracture reproduces the shape and outline of the weapon, in effect leaving the signature or imprint of the object on the skull. This helps identify the weapon used.
Step 4: The other options are different entities. Suture displacement, contrecoup injury (a contusion opposite the point of impact) and fracture at the foramen magnum (ring fracture) do not carry the imprint of the weapon.
Conclusion: Signature fracture is a depressed skull fracture, hence option A.
