Abstract: | During the course of a routine analysis of a cemetery burial population associated with the medieval hospital of St Giles, Brough, North Yorkshire, the partially excavated burial (No. 1423) of a priest, as identified through the associated chalice and paten dating to the medieval period, was observed to exhibit osseous changes commensurate with those of an untreated slipped proximal femoral epiphysis. Secondary osseous changes were noted that may indicate habitual positional behaviour subsequent to the injury. |
