Spondylodiscitis is a combination of
discitis
Discitis, or diskitis, is an infection in the intervertebral disc space that affects different age groups. Symptoms include severe back pain, leading to lack of mobility. In adults, it can lead to severe consequences, such as sepsis or epidural ...

Causes
Spondylodiscitis is the most common complication of
sepsis
Sepsis is a potentially life-threatening condition that arises when the body's response to infection causes injury to its own tissues and organs.
This initial stage of sepsis is followed by suppression of the immune system. Common signs and s ...

Diagnosis
The main methods to diagnose a spondylodiscitis are magnetic resonance imaging

(MRI), biopsy and microbiological tests such as PCR to determine an infectious cause.
Treatment
Approximately 90% of cases can be treated conservatively. In the absence of spinal cord/nerve root compression and lack of data on instability of the inflamed segment, conservative treatment with:
* Antibiotics - empirical treatment should start AFTER biopsy material for microbiological testing is obtained (PMID 27082590). The following empirical treatment may be administered for a total of 6 weeks (PMID 26872859): - Ceftriaxone 2x2g and Clindamycin 3x600mg i.v. for 2 weeks - Ciprofloxacin 2x500mg and Clindamycin 4x300mg p.o. for 4 more weeks If the pathogen can be identified - antibiotic treatment should be adapted to the susceptibilities of the microorganism.
* Bed rest
