Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this prospective, observational study was to evaluate frequency and characteristics of low-grade infections of the intervertebral discs in an unselected real-life patient population undergoing surgery for degenerative pathologies of the spine.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Low-grade infection of the intervertebral discs, causing disc degeneration and consecutive pain and disability is reported in literature. Microorganisms are also held responsible for Modic Changes of the vertebral bodies.

Patients underwent surgery for degenerative pathology of the spine independent of this study. After being informed about this study, all patients giving written informed consent who met eligibility requirements were included. Treatment of the patients was independent of this study. Intraoperative removed disc tissue was examined using microbiological culture, viral polymerase chain reaction (PCR), and histopathological analysis.

Other used data were demographic data (Gender, age), Modic Changes on MRI, preoperative Oswestry Disability Index (ODI), preoperative Neck Disability Index (NDI), and preoperative C-reactive protein (CRP).

Frequency of positive microbiological culture findings, viral PCR, and inflammation signs in histopathological analysis was described, and statistical analysis was performed to identify if any of the above mentioned parameters influences the frequency of positive microbiological culture and Modic Changes significant.
