[Percutaneous CT-controlled puncture and drainage of spondylodiscitis--a minimally invasive method].

PURPOSE

Is there an absolute operative indication for the abscess-forming spondylodiscitis or is a curing also possible with minimal invasive procedures?

METHOD

In a retrospective study over a period from 1986 to 1993, 40 patients with a spondylodiscitis of the thoracic and lumbar spine were treated and then followed up over two years in our Department of Orthopedic Surgery. Using a CT-controlled method of minimal invasive punction and drainage of the abscessed forms of spondylodiscitis, it was to be settled whether these therapeutic procedures result in a normalization of the biochemical inflammatory parameters (CRP) and in a normalization of the CT--as well as MRI-findings.

RESULTS

7 of the 40 patients had a spondylodiscitis with a local abscess, further 7 patients had a gravidation abscess. 92.5% of the cases were treated conservatively and minimal invasively, respectively. In 11 patients the minimal invasive procedure was used in addition to conservative therapy. 3 cases had to be operated on. A recurrence of the spondylodiscitis was seen in 1 patient; complications (n = 2; 1 x pneumonia, 1 x venous thrombosis) occurred in 5% of all patients.

CONCLUSION

Minimal invasive therapy with CT-controlled punction or drainage may be a good alternative to the operative intervention in the predominantly old and multimorbid patients with abscessed forms of spondylodiscitis. The risk is minimized, the immobilizing period was 8.7 weeks on average.
