The purpose of study is the development of scientifically based diagnostic criteria for determining body length, age, gender and degree of muscle development by individual parameters of the shoulder blade to identify the person. The material was 108 corpses of people aged 19 to 99 years old from the Central region of Russia in 2016, whose death came from diseases of the cardiovascular system, acute poisoning with ethanol and/or narcotic drugs, combined mechanical injury to the body. We used morphological, morphometric and osteometric research methods, as well as methods of mathematical statistics. New methods have been developed to determine the body length, gender, age and degree of muscular development by individual parameters of the shoulder blade with a high degree of reliability. Using the proposed methods will reduce the number of osteological studies, reduce economic and time costs in general for conducting morphometric studies of bones, as well as increase the evidence-based significance of expertise in criminal proceedings.
