Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
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.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Among these 'big fours' parameters , the determination of sex is not only considered one of the most important parameters; but it can primarily cut half of the possible number of matching identities.
But it is also one of the simplest tasks in forensic investigation if the whole body is available; as the external and internal genitalia directly suggest the sex; however, the problem arises when dismembered body parts are found.
Nowadays, there are increased events of murders where the mutilation of a dead body is done by murderer to destroy all traces of identity,and additionally, there are increased events of mass disasters where dismembered body parts are found.
The pelvis is the best sex-related body part indicator, with 95% accuracy. However, it may not always be available. Recent studies have worked towards the sex determination potentials of other body parts.
Hands are one of the most sexually dimorphic parts of the human body.Therefore, sex determination based on radiologic examination of hand bones and hand dimension anthropometric measurements is of considerable importance.
Since the use of image processing techniques (e.g., radiography and computed tomography) in sex determination by osteometric measurements of hand bones is costly.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Group A: Males only
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 )
Anthropometric Measurements
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.
Group B:Females only
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.
