Bracing scoliosis



Scoliosis is a lateral deviation of the spine commonly exhibiting different patterns of curvature [1]. The basic curve patterns are named after the location of the major curve (e.g., thoracic, lumbar, thoracolumbar, double major, and double thoracic), but other specific classifications have been described [2]. In structural scoliosis, there is usually a certain amount of spinal torsion and a disturbance of the sagittal profile coupled to the lateral deformation [1]. Therefore, scoliosis must be more accurately regarded as a three-dimensional (3D) deformity of the spine and trunk, which may progress quickly during periods of rapid growth [1].

There is some evidence for the use of physiotherapy in the treatment of patients with spinal deformities. However, during the pubertal growth spurt (high-risk phase for progression), brace treatment is the most important mode of treatment [1]. In-brace correction and compliance correlate with outcome [13]. More asymmetric braces with increased corrective effect are preferable (Cheneau style) to the more symmetric Boston braces [13].

Brace treatment can effectively halt progression. A recent randomized controlled trial [13] demontrated that 72% of the United States and Canadian population compliant with SRS inclusion criteria on bracing [14] did not progress using the standard thoracolumbosacral orthosis (TLSO, mainly Boston type).

A retrospective series using CBA (classification based approach = Gensingen brace according to Dr. Weiss) in a sample fulfilling the SRS inclusion criteria of the studies on bracing revealed a success rate exceeding 95% [1415]. This was confirmed in another study using the correction principles according to Cheneau [16]. Recently, it was reported that 33% of a population demonstrating improvements of Cobb angle exceeding 5 degrees after weaning off the CBA braces, with none of the subjects requiring surgery [17].

Today many different bracing concepts are on the market with very different approaches. However, scoliosis is not differing so much. Therefore, not all braces on the market today can be regarded as being efficient and effective (Fig. 1).

Fig. 1. Many different approaches for the same deformity: Which approach does really work?

First of all we may acknowledge that independent studies (Fig. 2) have clearly shown that soft braces do not work, so there is no indication for this approach. The background on soft braces has been described in a paper by Weiss. More information on the background can be found here: A translation of this report can be found here.

Fig. 2. Independent prospective and randomized studies have shown that the SpineCor does not work as advertised. Scoliosis is a stiff deformity and a device allowing unlimited mobility will not correct scoliosis more than a t-shirt.

Therefore a standardization of brace treatment is long overdue as many patients sacrifice their quality of life to a tool without or with limited effect. Additionally many patients still are suffering in the braces as most of them are very uncomfortable to wear. Most of the braces just aim at pressing against the humps visible on the patients‘ body and compress the patients trunk which may lead to pain and limitation of breathing.

Today with the Gensingen brace according to Dr. Weiss a new area has begun. Scoliosis correction is no more achieved by compressing the patient, but with a corrective movement guided by the brace (Fig. 3).

With this new approach (Gensingen Brace according to Dr. Weiss / GBW) we achieve the best possible corrections with the smallest and most comfortable bracing series as available today. Patients in the range of the SRS inclusion criteria for brace treatment (20 – 40° Cobb) usually find the brace far more comfortable than other braces available today. And the patients treated with the GBW after treatment show a very good quality of life. With this new approach (GBW) we are able to not only stop curvature progression, but we may aim at final improvements as can be seen in the following.

The GBW is a CAD / CAM brace constructed on the basis of a simple classification. It can be made according to measurements and / or based on a patients‘ scan (Fig. 4 and 5):

Of course in more mature patients especially with curvatures exceeding 50° some problems may arise but these can usually be solved in short time so as to allow also the treatment of patients with curvatures exceeding 50° (Fig. 6).

Nowadays there is evidence that final improvements can be achieved as well:

This shows that stable corrections can be achieved when treatment starts early enough and if enough growth for correction can be expected. This case is described more deeply in a case report.

As a matter of fact in-brace correction depends on many factors. There is a clear negative correlation between age and in-brace correction. This means more mature patients at Risser 4 will not correct as easily as immature patients (e.g.. girls at 11 to 13 years of age).

Fig. 18. Some patients do not want to undergo surgery even with curvatures exceeding 80°. So we try to achieve some corrections also in curvatures of that size although these braces are not as comfortable to wear as braces for curve up to 50°and may need additional tools (with kind permission of Dr. Marc Moramarco, Scoliosis 3DC, Woburn MA, US)

In-brace correction also depends on the size of the curvature: The bigger the curve (Cobb angle) the smaller the in-brace correction.

In-brace correction also depends on curve pattern: While single curve patterns are more easily to correct double or triple curves are harder to correct. Especially the curve patterns with a high lumbar apex and a low thoracic apex has not enough lever arm to be correctable to a high extent. Even if in this pattern of curvature big improvement of the x-ray cannot be achieved the cosmetic outcome is beneficial when the patient wears the brace as prescribed. More information can be gained here.

Fig. 20. Double thoracic curves also do not correct to a very high extent, however these combined curves are cosmetically less obvious

About 5% of the patients with Adolescent Idiopathic Scoliosis (AIS) do not correct well although the bracing standard does not allow huge variations. In these cases a functional tethering of the spinal cord may be the reason. This has been described in a paper by Weiss et al.. But also without a large in brace correction in most patients from this population progression can be prevented. A paper on MRI shows the subtle signs of functional tethering, which may be treated by special exercises and extra corporal shock wave therapy (ECSWT).

We are proud to see more and more professionals are using this successful approach all over the world…..
