Evidence of disease was analyzed from the skeletal remains of 11 individuals dating to the post-Medieval period from church cemetery of St. Ilija in Serbia. Two individuals showed pathological condition affecting joints. It was supposed that first individual had been suffering from Legg-Calvé-Perthes disease. It seems that this condition remained untreated, with extensive bone remodeling, and that the deformity of femoral head and acetabulum caused secondary degenerative joint disease at a relatively early age of this individual. Second case was related to the bony akylosis of the hand finger, probably caused by Dupuytren's disease. In addition, we discussed development of differential diagnosis in both pathological conditions.
