Update on Imaging of Spinal Fixation Hardware.

Area of Science:

• Orthopedics
• Radiology
• Neurosurgery

Background:

• Instrumented spinal surgeries utilize fixation hardware for stabilization.
• Postoperative assessment of this hardware is crucial for patient outcomes.
• Potential complications can arise from spinal instrumentation.

Purpose of the Study:

• To discuss the radiologic assessment of spinal fixation hardware.
• To highlight the role of imaging in detecting postsurgical complications.
• To emphasize the importance of recognizing normal imaging findings for clinical management.

Main Methods:

• Review of standard postoperative assessment using radiography.
• Utilizing computed tomography (CT) and magnetic resonance imaging (MRI) for detailed evaluation.
• Familiarity with normal imaging appearance of implanted hardware and osseous arthrodesis progression.

Main Results:

• Radiography is the standard for initial postoperative assessment.
• CT and MRI are valuable for detecting hardware complications like infection, pseudarthrosis, and malposition.
• Normal imaging progression aids in identifying deviations and potential issues.

Conclusions:

• Radiologic assessment is vital for evaluating spinal hardware post-surgery.
• Advanced imaging techniques (CT, MRI) are essential for diagnosing complications.
• Knowledge of normal imaging findings facilitates timely and effective clinical management of spinal hardware patients.
