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

Area of Science:

• Orthopedic Surgery
• Medical Imaging
• Biomedical Engineering

Background:

• Routine ionizing imaging for post-surgical hip complications presents risks and costs.
• Non-ionizing imaging techniques are needed as alternatives or complements.
• Infrared thermal imaging (ITI) shows promise for evaluating inflammation.

Purpose of the Study:

• To report a case of hip dislocation managed non-surgically.
• To evaluate the utility of ITI as a complementary diagnostic tool in this case.
• To assess ITI's ability to monitor inflammation and exclude infection.

Main Methods:

• A patient with a dislocated total hip prosthesis underwent non-surgical reduction.
• Routine clinical and radiographic assessments were performed.
• Infrared thermal imaging was used bedside as a complementary diagnostic tool.

Main Results:

• Infrared images were easily acquired at the bedside and well-tolerated.
• Thermal imaging provided feedback on local inflammation post-reduction.
• The technique helped differentiate inflammation from potential infection.

Conclusions:

• Infrared thermal imaging is a feasible, non-ionizing method for evaluating hip prosthesis patients.
• It can serve as a complementary tool to monitor inflammation and rule out complications like infection.
• ITI offers a cost-effective and safe alternative to traditional imaging in specific clinical scenarios.
