Use of arthroscopy in wrist instabilities.

Wrist arthroscopy is one of the most important tools in diagnosis of wrist pathologies. This invasive method of diagnosis can provide us a true view of cartilage, ligamentous stability giving also a possibility of dynamic probing. Diagnosis is a first step of the arthroscopy.

Understanding wrist instabilities.

The wrist function is to position the hand optimally for specific tasks. To do so, the wrist must have a large arc of motion while maintaining its stability. The traditional row theory, and the columnar theory were developed to explain how the columns and rows affect wrist motion and stability.

Helical computed tomography alone compared with plain radiographs with adjunct computed tomography to evaluate the cervical spine after high-energy trauma.

Background: Current literature supports the use of the three-view plain-radiograph series supplemented, when necessary, with helical computed tomography to evaluate the cervical spine in patients who have sustained trauma injury. The purpose of this study was to determine if helical computed tomography alone can be used to evaluate the cervical spine for acute osseous injury following high-energy trauma, thus eliminating the need to make radiographs.

Methods: Patients were prospectively evaluated with helical computed tomography scanning of the cervical spine and standard three-view plain radiography.
