Computed tomography in traumatology with special regard to the advances of three-dimensional display

Abstract

There is a variety of methods to aid in the diagnosis of fractures requiring operative treatment. A computer program that produces pseudo-three-dimensional (3D) images from sets of axial computed tomograms is used for examining fractures in areas of complex skeletal anatomy. The resulting reconstructions, representing the surface in a form similar to that of anatomic preparations, can facilitate the process of diagnosis. They are also valuable for planning operations. The 3D information can be used to define the size, shape, and location of the various fracture types. We have used the technique in more than 500 patients with injuries to the skull, spine, acetabulum, sternoclavicular joint, shoulder, knee, and calcaneus and are able to demonstrate the benefit of special investigation protocols.

Evaluation of Letournel and Judet Classification of Acetabular Fracture with Plain Radiographs and Three-Dimensional Computerized Tomographic Scan

“…3). 1,2,4 One way to measure the accuracy and efficiency of a classification is to measure the intraobserver reproducibility and interobserver reliability, which is the measurement of the agreement of one observer at different periods of time and among different observers, respectively.…”

Indications for computed tomography (CT-) diagnostics in proximal humeral fractures: a comparative study of plain radiography and computed tomography

“…Various authors stated that the CT is a helpful diagnostic tool for evaluation of proximal humeral fractures. Nevertheless, those reviews included recommendations without exact definition of their use [ 2 , 3 , 30 ]. Because the visualization could be further improved by using a thinner layer thickness up to 0.75 mm, this method is now more often used for diagnostics in proximal humeral fractures.…”

“…Therefore, precise indications for CT in proximal humeral fractures are not established. In addition, its benefit remains unclear [ 2 - 6 ].…”

Traumatic Shoulder Injuries: A Force Mechanism Analysis of Complex Injuries to the Shoulder Girdle and Proximal Humerus

“…Although not typically indicated for acromioclavicular joint injuries, CT may be helpful for assessment of a possible occult fracture and for evaluation of radiographically ambiguous clavicle positioning [25,26]. Use of MRI improves visualization of acromioclavicular and coracoclavicular ligament injury through direct identification of ligament disruption, identification of related blood or edema, or identification of a radiographically occult clavicle or coracoid process fracture [9,24] (Fig.…”
