This gallery of orthopedic devices is designed as a quick reference for readers who wish to identify an unfamiliar device in the extremities or pelvis (1), specifically a device used for fracture fixation or in joint arthroplasty. The basic goal of fracture fixation is to stabilize the fractured bone, to enable fast healing of the injured bone, and to achieve early mobility and full function of the injured extremity. The basic principles of fracture fixation and the complications associated with them were discussed in previous RadioGraphics articles, as well as other references (2–8). Herein, we illustrate many of the fracture fixation devices found in everyday practice (Figs 1–27). In addition, in a previous article, we illustrated the most commonly used joint prostheses and addressed important points for the correct recognition and radiologic evaluation of these devices (9). Proper placement of these devices and complications associated with them were also discussed (3–10). Herein, we present an overview of many common joint prostheses (Figs 28–43).
In summary, we provide a comprehensive overview of important orthopedic devices frequently found in the extremities and pelvis. It is intended to allow the reader to identify a device generically and to understand its purpose. It is important to understand the purpose of and proper function for a medical device, but it is not important—and is probably impossible—to describe every device by its proper brand name. For a detailed discussion of a particular device, the reader should refer to the appropriate references cited. A gallery of spinal devices and devices found in the head, neck, chest, abdomen, and pelvis will appear in a subsequent article (11).
