Home Office pathologist Dr Mark Egan said the possible causes were loss of blood, a head injury, or asphyxiation, but could not tell which of those was the case.
He told the court that items including a metal pan, two broken glass vases and a wooden stick with protruding screws "were compatible" with Ms Wrightson's many injuries.
She suffered "a bare minimum" of 103 cuts and bruises, including 15 slash wounds to her head.
