Juvenile scurvy from Late Medieval Knin, Croatia

In this study, we examine the scurvy associated skeletal lesions among juveniles from the late Medieval site Uzdolje-Grablje in Croatia. The study aims to establish a demographic pattern of scurvy using existing diagnostic criteria. The sample consists of 16 well-preserved and fairly complete juveniles, excavated from a cemetery dating to 1420-1920. Skeletal remains were analyzed macroscopically for signs of porosity and new bone formation. Scurvy is diagnosed using the "Ortner criteria" of cranial and postcranial lesions. Depending on the location of the lesions, individuals were diagnosed with either scurvy or possible scurvy. Half of the individuals in our sample are diagnosed with scurvy, with additional 25% being diagnosed with possible scurvy. Along with porotic lesions, all individuals diagnosed with scurvy/possible scurvy showed new bone formation on at least one skeletal element. The occurrence of lesions associated with scurvy in our sample is unusually high. Instead of focusing solely on diet and insufficient intake of the vitamin C, a more likely explanation lies in the synergy between diet, exposure to infections, and the environment.
