Abstract
STANDARD PROCEDURE
As a rule, postoperative imaging is carried out after spinal interventions to document the exact position of the implant material.
INFORMATION
Imaging is absolutely necessary when new clinical symptoms occur postoperatively. In this case a rebleeding or an incorrect implant position abutting a root or the spinal cord must be proven. In addition to these immediately occurring postoperative clinical symptoms, there are a number of complications that can occur several days, weeks or even months later. These include the failed back surgery syndrome, implant loosening or breakage of the material and relapse of a disc herniation and spondylodiscitis.
REVIEW
In addition to knowledge of the original clinical symptoms, it is also important to know the operation details, such as the access route and the material used.
RECOMMENDATION
In almost all postoperative cases, imaging with contrast medium administration and corresponding correction of artefacts by the implant material, such as the dual energy technique, correction algorithms and the use of special magnetic resonance (MR) sequences are necessary.
RECOMMENDATION
In order to correctly assess the postoperative imaging, knowledge of the surgical procedure and the previous clinical symptoms are mandatory besides special computed tomography (CT) techniques and MR sequences.
