Fracture Fixation

Many fractures are treated non-operatively. However, a large number of fractures require operative treatment. The basic goals of fracture fixation are to stabilize the fractured bone, enable fast healing of the injured bone, and return early mobility and full function to the injured extremity.

Foreign Bodies

Foreign bodies are uncommon, but they are important and interesting. Foreign bodies may be ingested, inserted into a body cavity, or deposited into the body by a traumatic or iatrogenic injury. They may go unrecognized or mistaken for a normal structure or a normally functioning medical device.

Joint Arthroplasty

The most frequent orthopedic procedures are everyday fracture reductions, immobilizations, and fixations. The next most important and frequently performed orthopedic procedures are joint arthroplasties in which a portion of a joint or the entire joint is replaced by a surgically placed prosthesis. In the United States alone there are approximately 1 million total joint replacements annually.

Gallery of Orthopedic Medical Devices

The gallery is designed as a quick reference for those wishing to identify an unfamiliar orthopedic medical device found on a radiologic study. The devices are grouped by body regions: neck and spine; dental; and orthopedic devices (fracture fixation and joint arthroplasty). Various device complications are also illustrated.

Dental Apparatus

The teeth, mandible, and maxilla are frequently encountered on head and neck images for trauma or infection or when evaluating orthopedic apparatus placed for cervical spine fixation and stabilization. Dental apparatus is not unimportant and is generally poorly understood and evaluated by most radiologists and other physicians.
