Abstract :

The aim of this paper is to evaluate the elbow carrying angle of the elbow joint by radiographic examination in normalchildren and adult inorder to determine the range of normality according to age and skeletal maturity proposing a simple and reliable method for measuring it.Carry angle is considered as the secondary sexual character. The distal end of the humerus and the proximal end of ulna plays a major role in the formation of �Carrying angle� and has been examined for sex difference. The measurements of the humerus (Trochlear angle and Inclination angle of Olecranon fossa) and also the three measurements of the ulna (Olecranon–coronoid angle, length and width of inferior medial trochlear notch) were devised for the study. The humeral angles failed to prove any sexual difference, but the angle and dimensions of ulna exhibited significant result[1]. The present study also devised the correlation of carrying angle with the length of the forearm and the height of the person.The carry angle of the elbow should also be considered in the construction of elbow prosthesis and identification of skeletal remains. This paper aims at using the advanced measurement software in Digital Radiography (DR) and Computed Tomography (CT), the carrying angle being measured on radiographs, the use of the advancedpostprocessing software in DR and CT. This paper also aims to provide information that Medical Imaging and Radiography plays significant roles not only in diagnoses of pathologies but also in Forensic Radiography, where radiographs are taken for age, sex determination ( for example,medical legal cases, age retirement, adolescence age for marriage etc.).
