Sagittal diameter measurements of the bony cervical spinal canal in children
Insights
This study established normal sagittal diameter values for the pediatric cervical spinal canal in children aged 3-14. These findings aid in identifying spinal canal abnormalities in children.
Area of Science:
- Pediatric Radiology
- Orthopedic Surgery
- Developmental Anatomy
Background:
- The cervical spinal canal's dimensions are critical for spinal cord health.
- Establishing normative data in pediatric populations is essential for diagnosing congenital or acquired abnormalities.
- Previous studies may lack comprehensive data across a wide pediatric age range.
Purpose of the Study:
- To determine the normal range of the sagittal diameter of the bony cervical spinal canal in children aged 3 to 14 years.
- To investigate the relationship between age, body height, and cervical spinal canal width.
- To provide reference values for identifying pathological narrowing or widening.
Main Methods:
- Radiological assessment of the sagittal diameter of the cervical spinal canal in 120 children (aged 3-14).
- Data stratified by age groups (3-6, 7-10, 11-14 years) with calculation of mean values and standard deviations.
- Correlation analysis between body height and spinal canal width.
Main Results:
- Cervical spinal canal sagittal diameter shows a continuous increase with age and body height.
- A slight decrease in diameter is observed from the foramen magnum to C3, followed by stabilization.
- No statistically significant gender-based differences were found.
Conclusions:
- Normative values for pediatric cervical spinal canal sagittal diameter were established.
- These reference ranges are valuable for the radiological detection of spinal canal stenosis or dilation in children.
- The findings support the use of these measurements in clinical pediatric orthopedic and neurosurgical assessments.
Abstract:
Radiological measurements of the sagittal diameter of the bony cervical spinal canal were performed on 120 children, aged 3 to14 years old. For the age groups 3 to 6, 7 to 10 and 11 to 14 years the appropriate mean values were calculated with standard deviations. In addition the relation between body height and width of the spinal canal was investigated. The values show a continuous increase with advancing years and increasing body height. In all age groups the sagittal diameter decreases slightly from the foramen magnum to C.3 and then remains nearly constant. There are no statistically significant differences between boys and girls. The "normal values" obtained facilitate the detection of pathological cases where there may be widening or narrowing of the cervical spinal canal.
