Abstract:
We analysed 13 cases of lumbar disc infection following surgical discectomy. Two groups of patients were identified. The six patients in group A reported that the initial symptoms of discitis had appeared a mean of 15 days after surgery; on average, antibiotic treatment was started 31 days following operation and continued for 62 days, and symptoms regressed after 3.9 months. Four patients showed moderate changes, while two had extensive osteolytic lesions of one or both vertebral bodies adjacent to the involved disc. In the 7 cases in group B, discitis was suspected a mean of 5 days and antibiotics were initiated a mean of 8 days following surgery; on average, symptoms regressed 1.8 months after operation. Only four patients showed vertebral radiographic changes and none had marked destructive lesions. In both groups erythrocyte sedimentation rate exceeded 70 mm/h in cases in which discitis was suspected. Tomograms and magnetic resonance studies were the most diagnostic imaging studies in the initial stages of the disease. All patients obtained satisfactory clinical results at the last follow-up. Careful observation of the early postoperative clinical course usually allows detection of disc space infection. Early and adequately prolonged antibiotic treatment may shorten the course of the disease and avoid extensive osteolytic vertebral lesions.
Insights
Early detection and prompt antibiotic treatment are crucial for managing lumbar disc infection after surgery. This approach can shorten recovery times and prevent severe vertebral damage.
Area of Science:
- Orthopedics
- Infectious Diseases
- Neurosurgery
Background:
- Lumbar disc infection (discitis) can occur post-surgical discectomy.
- Prompt diagnosis and treatment are essential for favorable outcomes.
Purpose of the Study:
- To analyze outcomes of lumbar disc infection following surgical discectomy.
- To identify factors influencing disease progression and recovery.
Main Methods:
- Retrospective analysis of 13 patients with post-discectomy lumbar disc infection.
- Categorization into two groups based on symptom onset and treatment timing.
- Evaluation of clinical course, radiographic changes, and treatment response.
Main Results:
- Group A (delayed treatment) experienced longer symptom regression (3.9 months) and more severe osteolytic lesions.
- Group B (earlier treatment) showed faster regression (1.8 months) and fewer radiographic changes.
- Elevated erythrocyte sedimentation rate (>70 mm/h) indicated suspected discitis.
- Tomography and MRI were key diagnostic tools.
Conclusions:
- Close monitoring of early postoperative symptoms aids in detecting disc space infections.
- Early, prolonged antibiotic therapy can improve clinical outcomes and reduce vertebral damage.
