Correct Answer » A Explanation |

Fracture à la signature (signature fracture) refers to a depressed skull fracture where the size and shape of a depressed skull fracture may give information on the type of weapon used or direction of trauma
The name comes from the fact that the pattern of fracture reflects the type of weapon used (signature of the weapon over skull).
Essentially, the weapon “signs” its identity on the skull through the distinctive depression pattern it creates.
Key points:
Caused by heavy weapon with smaller striking surface — hammer, axe, brick or chopper
The part of the skull which is first struck shows maximum depression
Helps forensic experts identify the weapon used and reconstruct the assault
D. Ring Fracture- This type of fracture often results from a forceful impact to the head, such as a blow or a fall from a height, where the force is transmitted along the axis of the spinal column to the skull.
– The term is derived from its characteristic circular pattern around the foramen magnum.
B. A fissured fracture – Fissured or linear fractures are simple cracks in the skull that do not typically encircle any specific anatomical landmark like the foramen magnum.
C. Separation of the suture – Involves the parting of the cranial sutures, which is distinct and not typically associated with the specific pattern observed in ring fractures.
