[Course and prognosis of congenital scoliosis]
Insights
Congenital scoliosis prognosis varies by anomaly type. Unilateral unsegmented bars show the most severe curve progression, averaging 7.6 degrees yearly, necessitating surgical intervention.
Area of Science:
- Orthopedics
- Pediatric Orthopedics
- Spinal Deformities
Background:
- Congenital scoliosis is a complex spinal deformity present at birth.
- Accurate prognosis and treatment depend on classifying the vertebral anomaly.
- Understanding progression rates is crucial for effective management.
Purpose of the Study:
- To evaluate the prognostic significance of different congenital vertebral anomaly types.
- To determine the rate of curve progression for various congenital scoliosis classifications.
- To guide treatment decisions based on anomaly type and progression.
Main Methods:
- Retrospective analysis of 75 patients diagnosed with congenital scoliosis.
- Classification of vertebral anomalies using a standardized scheme.
- Evaluation of curve progression based on anomaly type and location.
Main Results:
- Unilateral unsegmented bars demonstrated the most rapid progression (average 7.6 degrees/year).
- Unilateral hemivertebrae showed slower progression (1.5-2.3 degrees/year).
- Contralateral hemivertebrae and block vertebrae had minimal progression (<1 degree/year).
Conclusions:
- Congenital scoliosis prognosis is strongly influenced by the specific vertebral anomaly.
- Surgical intervention is recommended for unilateral unsegmented bars due to severe progression.
- Conservative management is often sufficient for other anomaly types.
Abstract:
75 patients (33 male, 42 female) with congenital scoliosis, diagnosed first time between birth and 40 years were examined. Type and site of the anomaly were classified and evaluated in accordance with a standardized scheme. The prognosis of congenital scoliosis depends strongly on the type of the anomaly. The differences of progression in the site of the abnormality are therefore minor. Unilateral unsegmented bars showed the most severe progression: the yearly rate of deterioration of the curve averages 7.6 degrees. Unilateral hemivertebrae showed 1.5 degrees (upper thoracic region) and 2.3 degrees (lower thoracic region). Two contralateral hemivertebraes and block vertebraes had a yearly rate of deterioration less than 1 degree. Operation is the treatment of choice in case of unilateral unsegmented bars. A conservative treatment is sufficient in most cases of other abnormalities.
