Brief summary in scientific language

Pyogenic spondylodiscitis is an infectious disease of the spine with an incidence of around 1: 250.000. The disease can either be caused by a bacterial (such as Staphylococci, Salmonella, Neisseria, Brucella), mycotic, viral or a parasitic spread (usually haematogenic), or by a iatrogenic infection following previous operation. In many cases, however, the infectious agent cannot be detected (Spondylitis fungax). A pyogenic spondylodiscitis is present as soon as both, the intervertebral disc and the adjacent vertebral bodies, are affected by infectious formations, and it thus occurs mainly in the anterior parts of the spine. The course of spondylodiscitis is variable and can range from no clinical signs to sepsis or neurological deficits due to epidural abscesses. Bacterial invasion of the intervertebral disc and destruction of the adjacent bony structures frequently leads to pronounced local pain and immobilization of the patients. The treatment depends on factors such as localization of the infection, grade of osseous destruction, neurological deficits and general symptoms. A conservative treatment with antibiotic agents and immobilization for several weeks is traditionally recommended in the early stage of the disease. Indications for operative treatment are significant neurological deficits caused by compression of the spinal cord or the cauda equina, spinal instability, progressive bony destruction/ deformity, or progressive pain after conservative therapy. Furthermore, surgical treatment should also be considered in patients with therapy-refractory pain, particularly in elderly patients, since longer periods of immobilization can cause thromboembolic complications and muscle wasting. The optimal treatment of the patient should thus be minimally incriminating, effectively restore the stability of the spine, and allow for fast pain reduction and ambulation. A sole minimal invasive instrumentation of the thoracolumbar spine using a percutaneous/ transmuscular pedicle screw and rod system meets these criteria and might be an effective and safe alternative to the traditional invasive operation methods. The aim of this study is to show that a minimally invasive instrumentation can effectively restore the stability of the thoracolumbar spine and avoid kyphotic deformity. In combination with standard antibiotic treatment this surgical procedure should be sufficient to cure the infection.

Interventions, Observational Groups

Arm 1:
We want to prospectively examine 25 patients, that we will operate with the described minimally invasive technique (A minimal invasive instrumentation of the thoracolumbar spine using a percutaneous/ transmuscular pedicle screw and rod system from behind). Perioperative laboratory and radiological data as well as intraoperative data will be collected during the hospital course. Pre- and postoperative clinical data collection will be supplemented by a questionnaire that incorporates the Charlson Comorbidity Index, the Oswestry Disability Index, the Visual Analogue Scale, and the EuroQol EQ-5D score. During follow-up visits at 6 weeks, 6 months, and 12 months clinical data will again be collected with help of the questionnaire, and the status of the instrumentation, the sagittal profile of the spine, as well as the formation of bridging bony spurs will be assessed by X-ray or CT scans, according to the standard of the respective study center.

Endpoints

Primary outcome:
Primary endpoint: Difference (vs. preoperative) Oswestry Disability Index (ODI) at 6 months
Secondary outcome:
Secondary endpoints: Pain and disability postoperative, at 6 weeks, 6 months, and 12 months (ODI; Visual Analogue Scale/ VAS; Macnab criteria), quality of life (EQ-5D-3L), time to mobilization, laboratory values (leukocytes, CRP), screw misplacement (Gertzbein/ Robbins), intra-/perioperative complications, reoperations, sagittal profile angles, formation of bridging bony spurs.
