Atypical manifestations of spinal infections
Abstract:
Because of alarming delays in the diagnosis and treatment of vertebral osteomyelitis we have reviewed our experience over the past 15 years. Of the 36 cases, 25 were pyogenic and 11 tuberculous. Because of late referral there was a delay from onset of symptoms to diagnosis of at least three months in 13 patients. The reason for this was the failure of the initial physician to consider osteomyelitis in the differential diagnosis of a febrile illness associated with back pain. The majority of our patients from the onset did not have intense localized pain, tenderness and a high fever which is the classical clinical picture in this condition. Seven patients with a long history required surgical exploration and debridement of the lesion in order to eradicate the infection. The remainder did well on 6 to 12 weeks of antibiotic therapy. None required spinal fusion. Ten of 11 patients with spinal tuberculosis had curettage of the lesion and spinal fusion. Patients with diabetes, malignancy, alcoholism, corticosteroid therapy and recent lower urinary tract surgery were found to be at particular risk of developing spinal osteomyelitis. Very often it was difficult to identify differences in the presentation of pyogenic and tuberculous infections.
Insights
Delayed diagnosis of vertebral osteomyelitis is common due to atypical symptoms and physician oversight. Early recognition and appropriate treatment are crucial for better patient outcomes in both pyogenic and tuberculous spinal infections.
Area of Science:
- Spinal infections
- Infectious diseases
- Orthopedic surgery
Background:
- Vertebral osteomyelitis presents diagnostic challenges, often leading to delayed treatment.
- Review of 36 cases (25 pyogenic, 11 tuberculous) over 15 years to analyze diagnostic delays and treatment outcomes.
Observation:
- Significant delays (≥3 months) occurred in 13 patients due to osteomyelitis not being considered in febrile illnesses with back pain.
- Classical symptoms (intense pain, tenderness, high fever) were often absent.
- Risk factors identified include diabetes, malignancy, alcoholism, corticosteroid use, and recent urinary tract surgery.
Findings:
- Antibiotic therapy (6-12 weeks) was effective for most pyogenic cases; 7 required surgical debridement.
- Spinal tuberculosis cases (10/11) necessitated curettage and spinal fusion.
- Distinguishing between pyogenic and tuberculous infections based on presentation was frequently difficult.
Implications:
- Emphasizes the need for increased physician awareness of vertebral osteomyelitis, especially with atypical presentations.
- Highlights the importance of prompt diagnosis and tailored treatment strategies for pyogenic versus tuberculous vertebral osteomyelitis.
- Suggests further research into differentiating pyogenic and tuberculous spinal infections and optimizing management for high-risk patients.
