Penetrating orbitocranial injury from kitchen sink

Mind Hacks' Vaughan spotted this curious sentence in the abstract of a scientific paper about a head injury:

We present a unique instance of a severe, high-energy, penetrating orbitocranial injury caused by a solid metallic rod that corresponded to the spray valve lever handle of a kitchen sink pre-rinse spray tap, which was fractured and projected at high speed for an unknown reason.

Penetrating ballistic-like frontal brain injury caused by a metallic rod.
