Reliability of criteria used for sexing of hip bones

For demarking a male from a female hip bone, the reliability of three most commonly used parameters i.e. chilotic line index, ischio-pubic index and acetabulo-pubic index were checked on 205 hip bones (143 males & 62 females). For all the three parameters "demarking points" were worked out. None of the parameters were promising in indentifying sex as a very low percentage of bones could be identified. The study concluded that the reliability of all the above parameters is doubtful
