• (1) be comprehensive and include all types of curves• (2) emphasize consideration of sagittal alignment• (3) help to define treatment that could be standardized• (4) be based on objective criteria for each curve type• (5) have good‐to‐excellent interobserver and 

intraobserver reliability• (6) be easily understood and of practical value in the 

clinical setting

Lenke classification of AIS is used to determine the appropriate vertebral levels to be included in an arthrodesis

Lenke Classification to define Non‐Operative treatment ?

LIMITATIONS

• Reliable but too complex for that purpose and questionable in mild scoliosis

Page 6: Scoliosis classifications Adopted for Non-operative Treatment

Lenke Classification to define Non‐Operative treatment ?

LIMITATIONSStructural curves (definition) • residual coronal curve on side‐bending radiographs of at least 25º (PT, MT, TL, L)

• >20º of kyphosis in its specific region

Old and recent literature on Bracing and physiotherapy

• (1) Single and double• (2) Thoracic, lumbar, thoracolumbar and double (Ponseti and Friedman 1950)

• (3) 3 single and 4 combined types (Moe and Kettleson (1970)

• (4) 4 single and 4 combined types (Lee, Denis, Winter and Lonstein modification 1993)

• (5) King classification (King, Moe, Winter and Bradford, 1983)

An unique classification adopted  for Non‐Operative treatment ?

• Different brace (and physiotherapy) concepts and principles

Page 12: Scoliosis classifications Adopted for Non-operative Treatment

Some PT schools and brace concepts use curve pattern specific classifications:

• Schroth (Published in several books and papers)• SpineCor (Published Blueprints)• Providence (Published Blueprints)• Lyon brace (scoliosis 2011 6:4)• Dynamic Derotation Brace (scoliosis 2010 5:20)• Chêneau type and derivates ( scoliosis 2010 5:1)• Progressive Action Short Brace PASB (scoliosis 2012 7:6)

Some brace concepts use curve use other criteria than curve pattern on brace design:

• Boston (Published Blueprints)• SPoRT (scoliosis 2011 6:8)

Conclusions

• ‘Lenke Classification’ has a limited use in Non‐Op treatment

• ‘Ponseti and Friedman’ has an explainable poor reliability

• ‘SRS terminology’ and ‘Moe& Kettleson’ could be still useful to describe population on brace and physiotherapy studies, if objective criteria are re‐discussed

Conclusions

• Following the specific principles, classification and blueprints for any particular brace  and physiotherapy concept is essential for success
