A complementary analytical tool for hip prosthesis dislocation: Thermal imaging in rehabilitation.

The use of routine ionizing imaging in identify and classify patients with dislocation or infection after surgery has some medical contraindication, in addition to risks associated with the ionizing load and elevated costs. A novel, less expensive and non-ionizing imaging technique, called infrared thermal imaging, can be proposed as a complementary method to routinely evaluate hip prosthesis patients and track their inflammation response following serious complications. Here we report a case of a total hip prosthesis which was dislocated during inpatient rehabilitation, and ultimately reduced without surgical procedure. During the process, routine clinical and radiographic diagnosis was complemented with an infrared examination. The infrared images were easy to take bedside, without direct contact with the area of surgery, and well tolerated. After the dislocation reduction, the thermal imaging procedure provided important feedbacks on the local inflammation, helping to exclude other complications such as the infections.
