The spectrum of intervertebral disc-space infection in children
Insights
Early diagnosis of spinal infection in children is crucial. Technetium 99m polyphosphate bone-scanning offers an accurate and rapid method for diagnosing discitis (intervertebral disc-space infection) and vertebral osteomyelitis.
Area of Science:
- Pediatric infectious diseases
- Musculoskeletal infections
- Diagnostic imaging
Background:
- Discitis, intervertebral disc-space infection, and vertebral osteomyelitis are related spinal infections.
- Diagnosis of spinal infections in children is often delayed.
- Bacterial etiology is probable for this spectrum of disorders.
Purpose of the Study:
- To evaluate diagnostic methods for pediatric spinal infections.
- To highlight the challenges in early diagnosis.
- To assess the utility of bone-scanning in pediatric discitis.
Main Methods:
- Studied forty-one children with symptomatic disc space narrowing, fever, and elevated erythrocyte sedimentation rate.
- Utilized Technetium 99m polyphosphate bone-scanning for diagnosis.
- Collected blood and biopsy cultures for microbiological analysis.
Main Results:
- Diagnosis of spinal infection was frequently delayed in the studied children.
- Technetium 99m polyphosphate bone-scanning demonstrated accuracy, speed, and safety for early diagnosis.
- Positive cultures were obtained in 34% of patients.
Conclusions:
- Discitis in children represents vertebral osteomyelitis with disc involvement.
- Early diagnosis of spinal infections is essential for effective management.
- Bone-scanning is a valuable tool for the early detection of pediatric discitis.
Abstract:
Discitis, intervertebral disc-space infection, and vertebral osteomyelitis form a spectrum of disorders with a probably common bacterial etiology. We studied forty-one children who had symptomatic narrowing of the disc space associated with fever and an elevated erythrocyte sedimentation rate and found that the diagnosis of infection in the spine was usually delayed. Technetium 99m polyphosphate bone-scanning proved to be an accurate, rapid, and safe method of establishing an early diagnosis of infection. A positive culture of blood or biopsy material was found in 34 per cent of all the patients (half of the patients for whom cultures were obtained). The clinical and roentgenographic picture that develops is determined both by the virulence and extent of infection and by the resistance and regenerative capacity of the host. Discitis in children is a vertebral osteomyelitis with disc involvement.
