Classification
Postural Kyphosis
- Parents concerned with postural roundback deformity
- Clinical gentle rounding of the back rather than gibbus
- Xray required to rule out Sheurman’s or Congenital
Congenital Kyphosis
- Failure of formation or segmentation
- Stable versus unstable
- All have some risk of neurologic compromise & progression
| Type | Description | Prognosis |
|---|---|---|
| 1 | failure of formation | less favourable rate ~ 7°/year |
| 2 | failure of segmentation | more favourable ~ 5°/year |
| 3 | combined |
Sheurman’s Disease
- Aka juvenile rigid kyphosis
- Secondary to growth disturbance of the endplates
Types
- Typical (Thoracic)
- Rigid thoracic kyphosis in juvenile or adolescent spine
- Apex T7 –T9, compensatory lordosis of the cervical & lumbar spine
- Incidence .4-10%
- Onset approximately 10 years of age
- Thoracolumbar
- Apex T1- T12
- Lumbar
- Constant backache
- Typically males
- Hard labour & athletics are associated
- Reduction in Lordosis
Other Causes
- Post-Laminectomy Kyphosis
- Radiation Kyphosis
- Achondroplasia Kyphosis
