[Surgical management of spondylodiscitis. An analysis of 78 cases].
Spondylodiscitis is a rare bacterial infection of the spine with an inflammatory, destructive course. To obtain further information on the therapeutic management and clinical course of spondylodiscitis, we retrospectively investigated 78 patients after surgical intervention. Mean age was 64 years (+/-4.6 years; range 21-80 years), the mean length of stay 49 days (+/-8.2 days; 3-121 days) including 24 days (+/-4.7 days; 0-112 days) in ICU. In hospital mortality was 9%. The cervical spine was affected in 10%, the thoracic spine in 35% and the lumbar/sacral spine in 55% of patients. Abscess formation occurred in 65% and destruction of the vertebral body in 74%. A total of 75% of patients presented with neurological deficits which could be improved by surgical intervention in 82% of cases. 24 patients were treated by ventral debridement and stabilization alone, 20 patients with a combined dorsoventral method. Most patients (n=34) were stabilized via dorsal bridging instrumentation without ventral debridement of the focus. Of this group, 23 patients were initially scheduled for secondary ventral debridement but complete healing was achieved prior to this, so further surgical therapy was unnecessary. Successful cure was obtained in 92% of cases. Based on our findings, we favor a split surgical approach: initially with dorsal internal fixation only. Abscesses can be drained percutaneously. Ventral debridement and stabilization is only recommended if insufficient stability can be obtained by dorsal fixation alone, as shown by the persistence of infection or pain.
