imaging techniques. Conventional radiography. The most frequently used modality for the evaluation of bone and joint disorders and particularly traumatic conditions is conventional radiography. The radiologist should obtain at least two views of the bone involved at 90° angles to each other, with each view including two adjacent joints. This decreases the risk of missing an associated fracture, subluxation and or dislocation at a site remote from the apparent primary injury. In Children, it is frequently necessary to obtain a radiograph of the normal unaffected limb for comparison. Usually the standard radiography comprises Antero posterior and lateral views. Occasionally oblique and special views are necessary, particularly in evaluating complex structures such as the elbow, wrist, ankle and pelvis. A weight bearing view may be of value for a dynamic evaluation of a joint space under the weight of the body. Special projections such as those described in the following chapters may at times be required to demonstrate an abnormality of the bone or joint to further advantage. In the last decade, conventional radiography has evolved into digital radiography in most places allowing direct acquisition of a digital image that can be transferred to a picture archive and communication or packs station
