Summary
This study explains spondylolisthesis progression as a growth disturbance in children. It highlights that spina bifida occulta is a mechanical issue, and prognosis depends on age and dislocation severity.
Area of Science:
- Orthopedics
- Pediatric Spine Surgery
- Developmental Biology
Background:
- Spondylolisthesis affects 62 children, with functional anatomical studies on 25 growing spines.
- Understanding the macro-morphological behavior before and after spondylolisthesis is crucial.
Purpose of the Study:
- To analyze the progression of spondylolisthesis as a growth disturbance.
- To investigate the relationship between spina bifida occulta and spondylolisthesis.
- To determine the influence of age at onset on spondylolisthesis morphology and prognosis.
Main Methods:
- Functional anatomical studies on 25 growing human spines.
- Macro-morphological analysis before and after spondylolisthesis.
- Correlation of clinical presentation with radiographic findings.
Main Results:
- Spondylolisthesis progression is characterized as a growth disturbance.
- High incidence of spina bifida occulta is a mechanically induced osteochondrosis of the dorsal arc.
- Morphology varies with age of onset; differentiation between dysplastic and spondylolytic types is not indicated.
Conclusions:
- Prognosis is poorer in young children with kyphosis and high ventral dislocation.
- Age at onset significantly influences spondylolisthesis presentation and progression.
- Spina bifida occulta in spondylolisthesis is a consequence of mechanical stress on the dorsal arc.
