Introduction[edit | edit source]
Scoliosis is a three-dimensional abnormality of the spine that causes an observable deformity. Scoliosis is defined by the Cobb's angle of spine curvature in the coronal plane, and is often accompanied by vertebral rotation in the transverse plane and hypokyphosis in the sagittal plane. Cases of scoliosis can be categorised as:
- Congenital - present from birth due to defects of formation, segmentation or mixed ones.
- Idiopathic - Develop during growth
Idiopathic Scoliosis accounts for approximately 85% of cases and can be described as infantile, juvenile or adolescent depending on the age the scoliosis presented.
- Infantile - Infantile Scoliosis affects children between birth and the age of 3. This category represents about 1% of all idiopathic scoliosis in children with about 60% of those diagnosed being male.
- Juvenile - affects children between the ages of 4 and 10 years and accounts for 10–15 % of all idiopathic scoliosis in children. If left untreated curves may cause secondary cardiopulmonary complications. In those with curves of 30° or more it is more likely that the curve will progress, in 95 % of cases a surgical procedure is indicated.
- Adolescent - Adolescent idiopathic scoliosis (AIS) has the highest prevalence of the three categories. This type of scoliosis is present at age ten and lasts till the end of growth. Its prevalence is dependent on the curvature of the spine and gender of the patient.
Epidemiological studies have demonstrated that Idiopathic Scoliosis in young people over the age of 10 is occurs more often in females than males reaching a ratio of 4:1. Anwer et al. described a prevalence of 2,5% with a Cobb angle larger then 10 degrees. They also stated that a variety of risk factors may result in a higher curve progression. These factors include the following: female gender, age of 10–12 years, absence of menarche, presence of thoracic curves, curve size at presentation >25 degrees, Risser sign of 0-1, and residual growth potential.
Physical Therapy Management[edit | edit source]
Without a Brace[edit | edit source]
The role of exercise in the nonoperative management of adolescent idiopathic scoliosis is controversial. Most experts agree that exercise alone will not affect the progression of structural scoliosis. There is agreement, however, that a selective exercise program in conjunction with bracing treatment is beneficial. Moreover, it has been shown that physical exercises can have a positive influence on breathing function, strength and postural balance, and that they are useful
in reducing specific impairments and disabilities of patients with idiopathic scoliosis.
It is stated that exercises, based on the ‘Scientific Exercises Approach to Scoliosis’, compared with non-adapted exercises even reduce brace prescription. SEAS exercises should be performed with respect to active self-correction and are aimed at spinal stabilization, strengthening of the tonic muscles, improvement of balance and coordination, recovery and maintenance of physiological sagittal curves. Therapists avoid increasing the spine’s range of motion but instead focus mainly on spinal stability., , 
Likewise the global postural rehabilitation according to Schroth has results published in indexed literature. The Schroth treatment programme consists of correction of the scoliotic posture and breathing pattern with the help of proprioceptive and exteroceptive stimulation and mirror control. Schroth tries to achieve this correction using only active trunk muscle force. Thus the patients learn to raise themselves as far as possible from a position of solely passive support by spinal ligaments, which is thought to promote curve progression, and then to maintain the corrected posture in activities of daily living.,
Among other well-known excersise treatments are the ones of Mézières, Sohier and Klapp, unlike the previously mentioned treatments these have been remained almost unchanged over time.
With a Brace[edit | edit source]
According to the generally accepted indications for conservative management of idiopathic scoliosis, the brace treatment is considered a standard management for progressive curvatures of moderate Cobb angle; it is usually recommended for angles of 25 to 40 degrees and if residual growth of the spine is expected. Adolescent girls with idiopathic scoliosis having the Cobb angle above 45 degrees and subjected to brace treatment for more than one year revealed smaller clinical deformity of their back comparing to non-treated girls having similar Cobb angle. 
Recently a Cochrane review has been published about the present evidence of bracing in idiopathic scoliosis. They found very low quality evidence in favor of using braces, making generalization very difficult. The Cochrane review concluded that further research is necessary; in the meantime, patient choices should be informed by multidisciplinary discussion.
The SOHORT Guidelines Summation[edit | edit source]
- High variability among results of bracing is confirmed.
- It is clearly evident that other factors beyond the instrument (brace) influence the final results. These factors can include dosage, quality of bracing, compliance to treatment , family history, type of scoliosis and even a geographical distribution, but also team approach.
- Today it is not possible to state with any certainty which brace is better than the other.
Recommendations of the SOHORT Guidelines:[edit | edit source]
- Bracing is recommended to treat adolescent idiopathic scoliosis.
- Bracing is recommended to treat juvenile and infantile idiopathic scoliosis as the first step in an attempt to avoid or at least postpone surgery to a more adequate age.
- Casting is recommended to treat infantile idiopathic scoliosis to try stabilizing the curve.
- It is recommended not to apply bracing to treat patients with curves below 15 ± 5° Cobb, unless otherwise justified in the opinion of a clinician specialized in conservative treatment of spinal deformities.
Types of Brace[edit | edit source]
A lot of different braces can be considered when speaking about brace management in Idiopathic Scoliosis: soft braces, hard braces, full time braces, night time braces, TriaC, Spinecor, Wilmington brace, Rosenberg brace, Night time bending brace, Boston brace, LA brace, Chêneau brace and many others.  We only discuss the different bracing types mentioned by Schiller et al. (2010), because these are the most commonly used.
|Milwaukee brace (3)||
Plastic pelvic section with an anterior
and two posterior uprights connected superiorly by a neck ring
|Thoracic and double curves||Full time wear, unless sports and extracurriular activities|
|Wilmington brace||Custom-made plastic underarm TLSO. Designed as a body jacket.||Thoracic and double curves||Full-time wear (23 hours/dag)|
|Boston brace||Prefabricated polypylene pelvic module with a soft foam plyethylene lining||All scoliosis||Full-time brace|
|Dynamic Spine-Cor brace||Applied according to definitions contained in the Spine-Cor Assistant software||Uses a specific corrective movement dpendent on the type of the curve||20 hours a day for a minimum of 18 months|
|Charleston brace||Custom-molded spinal orthosis||All scoliosis||At night|
|Providence brace (4)||Polypropylene plastic from measurements or a plaster impression||All single and double curves||At night|
The great variation of braces applied today implies that RCT on brace treatment will never be able to illustrate what really can be achieved with braces. The only possibility would be to test braces of different standards one against each other in controlled trials. As there are prospective controlled trials showing the Boston brace is effective, to leave a control group of a future RCT in braces without treatment clearly is unethical.
Schiller et al. investigated the efficacy of the different bracing types listed above. The goal of bracing idiopathic curves remained consistent in the different studies: control the curve, prevent progression, and avoid surgical intervention. They concluded that despite success with the Boston, Spine-cor, Milkauwee and Wilminghton braces, non of them is superior to the others with regard to the main gaols of bracing. Future research also will be needed to compare full-time versus part-time bracing. 
Surgical Management[edit | edit source]
Literature showed that thoracic curves of 50°-75° progress 0,73°/year. Thus, most surgeons indicate surgery above this angle. The knowledge on what happens to the patient without treatment (natural history) is needed to support the decision whether to operate or not. The aim is to give the patient an acceptable quality of life.
Patients have to be aware that scoliosis surgery is still stigmatized with a rather archaic way of sacrificing function in young and otherwise healthy individuals.
The Pain associated with scoliosis is underestimated, there is poor agreement between surgeons and patients regarding the presence of pain. About ¾ of the patients report pain before surgery which is reduced after operation. 1/3 of the patients showed no change in pain. 1/5 showed an increase.
