Skeletal ossification progression studies are one of them and are admissible in court as unparalleled scientific evidence for age estimation. Age group of juveniles between 12 - 18 years is dealt with special laws for medico- legal cases.Aims & Objective: To observe age of appearance and fusion of ossification centers of hip joint and pelvic bone in adolescent population of Jaipur.Material & Methodology: An observational prospective study that used inclusion and exclusion criteria wasconducted.
