Stephanie Platt of Wheeling was taken into custody after the alleged fight with her sister.
When Ohio County sheriff's deputies responded after getting a call about a fight, they found the suspect and her sister spattered with blood.
According to Platt's sister, the 24-year-old spit on her and shoved her after they got into an argument.
The victim told police both combatants tumbled to the ground and then "Platt began hitting her on the head with the spatula."
The sisters' mother stepped into the middle of the fight, confiscated the spatula and threw it into weeds that were growing across the road.
Platt's sister was brought to the hospital with a scalp laceration. She also had a bite mark on her finger.
