Brief Summary

Forensic anthropometry is the traditional and basic tool of forensic anthropology. It's the science of obtaining systemic measurements of the physical dimensions of the human body. This, in turn, is a very important parameter in personal identification. Different anthropometric techniques are employed to determine sex from such fragmented body parts. Such anthropometric techniques aim to find cutoff points in the measurement of various body parts or bones that discriminate between males and females. Due to the effect of sex hormones, males are taller, larger and more strongly built than females, so measurements greater than the cutoff point are suggestive of a male and less than that are suggestive of a female.

Conditions

Sex Determination

Outcome Measures

Primary Outcomes (1)

• Sex Determination

  Evaluation of both males and females whom participated in the study for sex determination by comparing the accuracy of anthropometric hand measurements versus radiologic anthropometric parameters of hand bones

  6 months

Study Arms (2)

Group A: Males only

ACTIVE COMPARATOR

About 60 of male participants and will be subjected to : 1. Anthropometric hand measurements. -Left hands length, breadth and hand index will be estimated at first. \-- The hand will be placed on a flat surface with the palm facing upwards and the fingers extended and close to each other. 2. X-ray radiographs on the hand. The participants will undergo another examination by using 2D-images radiographs on the same hand. Posterior-anterior (PA) digital radiographs will be required for the left hand of the volunteers. The Osirix1 line-tool function will be used for measuring metacarpals on radiographs in (mm). Theses mrasurments: * Length superior ( LS ) * Medullary length ( ML ) * Mid-bone length ( MB ) * Length of the base ( LB )

Procedure: Anthropometric Measurements

Group B:Females only

ACTIVE COMPARATOR

About 60 of female participants and will be subjected to : 1. Anthropometric hand measurements. -Left hands length, breadth and hand index will be estimated at first. \-- The hand will be placed on a flat surface with the palm facing upwards and the fingers extended and close to each other. 2. X-ray radiographs on the hand. The participants will undergo another examination by using 2D-images radiographs on the same hand.

Theses mrasurments: * Length superior ( LS ) * Medullary length ( ML ) * Mid-bone length ( MB ) * Length of the base ( LB )

Procedure: Anthropometric Measurements

Interventions

Anthropometric Measurements PROCEDURE

1. Assessment of the accuracy of sex determination from hand indexes using anthropometric hand measurements. 2. Assessment of the accuracy of sex determination from the length of the metacarpals using x-ray radiographs on the same hand. 3. Determination of the best and least costly method for sex identification by comparing the effectiveness of the previous two methods.

Also known as: Radiologic Measurements

Group A: Males only; Group B:Females only
