Abstract

Low back pain is one of the most common pathologies worldwide. When conservative treatment fails to
yield good results, surgery is the recommended approach. Despite spinal fusion, some patients
continue to experience persistent low back pain. This is where a series of studies come into play to
detect the source of treatment failure. The use of bone scintigraphy with SPECT (single -photon
emission computed tomography) in combination with computed tomography (CT) has greatly improved
the anatomical localization of abnormalities found in SPECT. While pseudoarthrosis is a significant
cause of spinal fusion failure, in recent years, it has been observed that certain low-virulence pathogens
are also implicated in persistent low back pain. This is the focus of our s tudy, in which we identified
two patients with persistent low back pain after surgery, both of whom tested positive for chronic low -
grade infection using SPECT/CT.
