Prosthetics in antiquity-An early medieval wearer of a foot prosthesis (6th century AD) from Hemmaberg/Austria.

Even though the earliest prosthetic devices date to the Ancient Egyptian Empire and iconographic sources attest their use in the Greco-Roman world, archaeological evidence for this practice prior to 2nd millennium AD is very scant. In 2013, a skeleton dating to the Frankish period (6th century AD) was excavated at the Hemmaberg in southern Austria. The middle adult male was missing his left foot from above the ankle. In its place, an iron-ring and wooden remains were recovered and interpreted as a prosthesis replacing the lost foot. This represents one of the oldest examples of prosthetic limb replacement associated with the skeleton of its wearer in Europe to date. Analysis through macroscopic assessment, radiography and CT-scanning revealed healing of the lesion even though it may have initially been complicated by osteomyelitis. Atrophy of the left lower leg further indicates immobilisation and suggests survival of several years. Osteoarthritis in the knees and shoulder girdle provides tentative indications towards the functionality of the prosthesis, perhaps aided through a crutch. These findings are set against the historic, archaeological, bioarchaeological and social context of the man in order to discuss whether removal of the foot was due to medical, punitive or traumatic causes.
