This disability had been the subject of remedial medical treatment with copper-alloy plates. Their presence, only the fourth such treatment thus far recorded from the mediaeval period, and the sole example applied to a lower limb, suggests that monastic houses, or those buried at these establishments, and specifically those associated with the Cistercians, had preferential access to medical specialists.
