Teleradiology in orthopaedics.

Teleradiology is a means of electronically transmitting radiographic image files from one location to another. Technologic advances in digital imaging, telecommunications, digital storage, and viewing technologies have made teleradiology readily available and reasonably affordable. The five components of a teleradiology system include: a sending station, a transmission network, a storage device, a viewing station and, a software package. The advantage of teleradiology is the mobility of digital images. In contrast to plain radiographs that only can be seen in one location at a time, multiple persons who are at different locations can view digital images simultaneously. When applied to orthopaedic trauma applications, when the consulting orthopaedist is at a remote location from the patient, teleradiology has been shown to improve diagnostic accuracy, disposition planning of patients from emergency departments or outlying hospitals, and planning of surgical procedures. These systems also improve the comfort level of consulting orthopaedic surgeons and potentially limit the risk of litigation for incorrect diagnosis. The quality, convenience, and effectiveness of teleradiology systems should improve as the technologies continue to mature. Having radiographic images available on handheld devices, such as cell phones, is likely to be a reality in the near future.
