Spina bifida occulta: lesion or anomaly?

Area of Science:

• Radiology
• Orthopedics
• Public Health

Background:

• Spina bifida occulta is a congenital vertebral anomaly.
• Its prevalence in the general population is not well-established.
• Understanding its incidence is crucial for accurate diagnosis and patient counseling.

Purpose of the Study:

• To determine the prevalence of spina bifida occulta in patients presenting to an accident and emergency department.
• To assess the age-specific incidence of this condition.
• To evaluate the clinical significance of spina bifida occulta.

Main Methods:

• Retrospective review of frontal radiographs from 653 accident and emergency outpatients.
• Exclusion criteria included backache, enuresis, and inadequate radiographs.
• Patients ranged in age from 2 months to 98 years.

Main Results:

• Spina bifida occulta was diagnosed in 22% of the study group.
• Incidence was higher in those under 40 (29.2%) compared to those over 40 (9.8%).
• The overall age-adjusted incidence was 17.3%.

Conclusions:

• Spina bifida occulta is a common anomaly with a significant prevalence in the accident and emergency population.
• The incidence is notably higher in younger adults.
• The findings support the notion that spina bifida occulta, in isolation, lacks clinical significance.
