X-ray examination:
X-ray examination is one of the important means for clinical examination and diagnosis of disease in orthopedic and traumatological department. Fracture and dislocation as well as their site, type, extent and treatment effect of the fracture and dislocation may be determined. Parenchymatous lesion of bone and joint as well as the nature, site, range and extent of the lesion and the relation of the lesion to the soft tissues around it may be investigated and determined. Bone age may be decided and the condition of skeleton in growth and development may be inferred. Influence of some nutritional and metabolic diseases on the bone and its severity may be observed. And also some diseases can be ruled out, and some similar diseases can be differentiated.

Roentgenoscopy: There are two kinds of flu-ororoentgenography and X-ray television diagnosis. Fluo-roscopy is mainly used for the examination of fire injury, scanning, localization and extraction of foreign body, reduction and check of traumatic fracture and dislocation.

Plain radiography: It is suitable for all bones and joints. Generally eutopic and lateral radiography is used for long bones of limbs, joints and vertebrae; for some special parts, oblique, or tangential, or axial radiography is needed.

Tomography: It is also called laminagraphy. This can make any one layer of internal tissues of the body develop in an X-ray film, and with the images of the other layers of the tissues being indistinct. Therefore, it can reveal a small focus, and determine the depth of the focus for the purpose of diagnosis. It is commonly used for diagnostic examination of osteoarticular tuberculosis, osteomyelitis and tumor of bone.

Stereoroentgenography: It can show a spatial relationship of a local tissue or structure to the tissues or structures in front of, or behind, or near, or far away from it, giving a stereoscopic conception. And it can also reveal the depth and range of focus in the thick part. It is mainly used for examination of a complex structure or a thicker part such as the skull, thorax, pelvis, and vertebrae, etc.

CT scan: Computerized tomography (CT) can give a cross-sectional image of the examined part. It is commonly applied in examination of diseases of the vertebrae, pelvis, and bone and joint of limbs.

MRI examination: Magnetic resonance imaging (MRI) has the advantage of multiple parameters, high resolving power of the soft tissues, and no harmful radiation. It can give a sectional image of any cross section, coronal section or sagittal plane. It is commonly used for the examination of diseases of the vertebrae, pelvis and limb joints.
