Innovation

Innovative: introducing new ideas; original and creative in thinking (Oxford Dictionary)

For the conservative management of spinal deformities to progress, we must be innovative; not only in brace design, but in the framework we use to approach treatment

Recognition of Great Polish innovators

Nicolaus Copernicus (1473-1543)

Mathematician, astronomer, physician, classical scholar

Developed the model that earth is not the center of universe

Published the book De Revolutionibus orbium coelestium

which was a major contribution to the scientific revolution

Fryderyk Chopin (1810-1849)

Composer and virtuoso pianist during Romantic era

Renowned as one of the leading musicians of his era

Invented the concept of instrumental ballade , later

used by composers including Johannes Brahms & Franz Liszt

Recognition of other Polish innovators

Marie Sklodowska-Curie (1867-1934) Physicist and chemist; Pioneered research on radioactivity

Arguably the most famous female scientist

First woman to win a Nobel Prize

Only person with Nobel Prizes in two different sciences

Lech Walesa (1943-) Credited with changing the Polish political system

Founded Poland’s first independent trade union “Solidarity”

which facilitated the fall of the communist regime

Awarded Nobel Peace Prize in 1983 for human rights activism

Recognition of inspirational Polish innovators

Pope John Paul II (Karol Wojtyla) (1920-2005)

Youngest Pope elected since 1846; served for 26 years

Fluent in 10 languages; visited 129 countries (most of any Pope)

Has been made a Saint by the Catholic church

Helped end communist rule in Poland and across Europe

Significantly improved the Catholic Church's relations with Judaism, Islam, the Eastern Orthodox Church, and the Anglican Communion

University of Iowa, NIH Funded, 2007 - 2013 Principle Investigator: Stuart Weinstein, MD

Study Director: Lori Dolan, PhD

Purpose:

“To compare the risk of curve progression in adolescents with AIS who wear a brace versus those who do not and to determine whether there are reliable factors that can predict the usefulness of bracing for a particular individual with AIS.”

BrAIST Study:Bracing in Adolescent Idiopathic Scoliosis Trial

Bracing is effective in stopping or slowing the progression of curves

Correlation between bracing outcome and orthotist skill and competence

Highlights need for advancement in research, orthotist training, and brace design

BrAIST: Peripheral Findings

72% of all braced participants had a successful outcome (stabilized or improved curves were considered success) 75% of randomized participants had successful outcome

48% of all non-braced participants had successful outcome (45% of randomized participants)

A significant positive association between hours of brace wear and rate of success exists

Bracing significantly decreased the progression of high-risk curves to the threshold for surgery

BrAIST: Research Study Results

365 total braces reviewed in case reports:

• 208 Boston (+46 “Boston-like” braces)

• 26 Wilmington (+13 “Modified Wilmington” braces)

Dr. Jacques Chêneau (Photo by Sanomed)

The Chêneau Brace Concept• Jacques Chêneau, MD initially designs

brace in 1960s and 1970s in France

• 1979: Dr. Chêneau publishes successes with novel brace design incorporating 3-D correction and regional derotation

• 1985 & 2004: Long-term follow up studies published demonstrating stable curve patterns

• Many design variations exist internationally

• Manuel Rigo, MD

• Developed in 1990s in Barcelona, Spain

Rigo-Chêneau Brace

• Asymmetrical, anterior-opening

• Custom fabricated from plaster cast or scan

• Elaborates on Chêneau’sregional derotation concepts with expansion spaces and three-dimensional correction principles

• Growing use by Rigo-educated orthotists in North America since 2004

Rigo-Chêneau Brace

• Curve patterns are categorized and respond consistently

• The categories provide a framework for brace fabrication

Rigo-Chêneau Brace

A corrected positive mould is created in order to provide highly selective pads and expansion rooms

Rigo-Chêneau BracePrinciples of Correction

A. Three-points systems in the frontal plane. Alignment inthe frontal plane

B. Regional derotation and pair of forces in the transversalplane for local derotation

C. Sagittal balance and physiological alignment

D. Breathing mechanics against the morphologicallordotization of the main thoracic spine

Progressive Action Short Brace (PASB)

• Developed by Dr. Lorenzo Aulisa

• Rome, Italy, 1976

• Institute of Orthopedics at the Catholic University of the Sacred Heart

• Treatment of lumbar/thoracolumbar curves

Progressive Action Short Brace (PASB)

• Asymmetrical, Anterior-opening

• Custom-made polypropylene brace from plaster mold

• Designed specifically for treatment of lumbar/thoracolumbar curves

Progressive Action Short Brace (PASB)Principles of Correction

Constrained dynamic of the spine

Inversion of the stress-loading distribution

Cast geometry

Deflexion DerotationTraction

Progressive Action Short Brace (PASB)

Two Phases of Treatment

Phase I: Plaster Cast Application of external actions

Progressive Action Short Brace (PASB)

Phase II: Brace Application The high upper margin of brace at concavity

prevents side bending toward concavity

The upper margin of brace at convexity ends just beneath apex, deflecting scoliotic curve during side bend toward convexity

Inferior margins reach pelvic/trochanteric region stabilizing the brace on pelvis

transverse profile of the superior brace consists of asymmetrical ellipses. This allows the spine to rotate towards the concave side only, providing continuous generation of derotation moments

• Definition of the derotation pushes

• Waist correction

• Elevation of the hemi-thorax

• Pushes on the ribs

• Shoulders

• Sagittal construction(change in kyphosis/lordosis)

ART Brace:Principles of correction

Correction occurs in Frontal and Horizontal plane

Axial Elongation and global detorsion

Detorsion is carried out with a fixed sagittal plane

ART Brace

Mobility takes place in frontal expansions and in torsion opposite to the curve

2 Axilla and Pelvic adjustable “clamps”

TLI brace (Thoracolumbar Lordotic Intervention)

Developed in 2002 by

Dr. Piet van Loon

Symmetric, posterior opening

based on concept described by M. Jansen in 1913

hypothesis that both thoracolumbar kyphotic & scoliotic spinal deformities are due to a dislocation of the thoracolumbar joint from its normal/optimal position

Mechanically, The TLI bracing concept is a Ponseti-type intervention, repositioning the joint in its optimal position to reduce shear, stress and deformative force.

TLI brace (thoracolumbar lordotic intervention)

Christine Colliard, MD and Charles Rivard, MD

St. Justine Hospital, Montreal, Canada, 1998

“Results are achieved not so much by the brace but by the

interaction of the brace with the patients Corrective Movement”

Corrective principles significantly different from traditional

thermoplastic TLSOs
