Cervical spine spondylodiscitis is a rare, but serious manifestation of spinal infection. We present a retrospective study of 20 consecutive patients between 01/1994 and 12/1999 treated because of cervical spondylodiscitis. Mean age at the time of treatment was 59.7 (range 34-81) years, nine of them female. In all cases, diagnosis had been established with a delay. All patients in this series underwent surgery such as radical debridement, decompression if necessary, autologous bone grafting and instrumentation. Surgery was indicated if a neurological deficit, symptoms of sepsis, epidural abscess formation with consecutive stenosis, instability or severe deformity were present. Postoperative antibiotic therapy was carried out for 8-12 weeks. Follow-up examinations were performed a mean of 37 (range 24-63) months after surgery. Healing of the inflammation was confirmed in all cases by laboratory, clinical and radiological parameters. Spondylodesis was controlled radiologically and could be achieved in all cases. One case showed a 15°kyph-otic angle in the proximal adjacent segment. Spontaneous bony bridging of the proximal adjacent segment was observed in one patient. In the other cases the adjacent segments radiologically showed neither fusion nor infection related changes. Preoperative neurological deficits improved in all cases. Residual neurological deficits persisted in three of eight cases. The results indicate that spondylodiscitis in cervical spine should be treated early and aggressive to avoid local and systemic complications.
Lumbar discectomy is one of the most frequent neurosurgical and orthopaedic procedures. In this study, a series of 43 consecutive patients operated with a minimally invasive technique referred to as "microscopically assisted percutaneous nucleotomy" (MAPN) is presented. After a follow-up period of 3 months, every patient was seen clinically, and after 12 months, telephone enquiries were performed by the first author. There were two recurrences. The results in improvement of sciatica and neurologic deficit corresponded to common microdiscectomy series with 80% excellent and good results. The MAPN method is compared with common microdiscectomy with regard to operating time, technical procedure, and especially in surgical indications. It proved to have the same effectivity in the treatment of lumbar disc herniations, however, with less approach damage.
After cement augmentation, close clinical monitoring is mandatory. A chest CT is pivotal in determining the interdisciplinary management approach in view of the availability of necessary expertise, facilities and the location of the cement emboli whether accessible by cardiac or vascular surgical means. The clinical presentation and its timing may vary and the patient may be seen subsequently by other health care providers obligating a wide-spread awareness for this serious entity among health care providers for this age group as spine surgeons, family and emergency room doctors, and institutional or home-care nurses. Most symptomatic central cement emboli may be treated conservatively.
This retrospective study evaluates eight patients with unstable fractures of the atlas vertebra, treated operatively in the Central Clinic Bad Berka between January 1995 and December 2001. In all cases, we were confronted with unstable and dislocated type III fractures according to Gehweiler, caused by an injured transverse ligament. Mean age was 34 years (range 20-49) in two women and six men. We introduce a new technique of direct reconstruction of the atlas vertebra. This technique leads to a stable ring construct that allows compression osteosynthesis of the fracture. Spinal fusion can be avoided, as can postoperative immobilization, since sufficient stability for functional postoperative treatment is achievable. The follow-up control 38 months (range 6-75) after surgery showed solid bony fusion in all cases, in one case after revision surgery. All patients showed good functional results, there was no need for analgesics and all patients could be reintegrated into their former occupation.
BackgroundThis is the first case series to describe adjacent segment infection (ASI) after surgical treatment of spondylodiscitis (SD).Materials and methodsPatients with SD, spondylitis who were surgically treated between 1994 and 2012 were included. Out of 1187 cases, 23 (1.94 %) returned to our institution (Zentralklinik Bad Berka) with ASI: 10 males, 13 females, with a mean age of 65.1 years and a mean follow-up of 69 months.ResultsASI most commonly involved L3–4 (seven patients), T12–L1 (five) and L2–3 (four). The mean interval between operations of primary infection and ASI was 36.9 months. All cases needed surgical intervention, debridement, reconstruction and fusion with longer instrumentation, with culture and sensitivity-based postoperative antimicrobial therapy. At last follow-up, six patients (26.1 %) were mobilized in a wheelchair with a varying degree of paraplegia (three had pre-existing paralysis). Three patients died within 2 months after the ASI operation (13 %). Excellent outcomes were achieved in five patients, and good in eight.ConclusionsAdjacent segment infection after surgical treatment of spondylodiscitis is a rare complication (1.94 %). It is associated with multimorbidity and shows a high mortality rate and a high neurological affection rate. Possible explanations are: haematomas of repeated micro-fractures around screw loosening, haematogenous spread, direct inoculation or a combination of these factors. ASI may also lead to proximal junctional kyphosis, as found in this series. We suggest early surgical intervention with anterior debridement, reconstruction and fusion with posterior instrumentation, followed by antimicrobial therapy for 12 weeks.Level of evidenceLevel IV retrospective uncontrolled case series.
