TRACE (Trunk Aesthetic Clinical Evaluation), a routine clinical tool to evaluate aesthetics in scoliosis patients: development from the Aesthetic Index (AI) and repeatability

<p>Abstract</p> <p>Background</p> <p>Aesthetic appearance is of primary importance in the treatment of adolescent idiopathic scoliosis (AIS), but to date tools for routine clinical practice have not become available. The aim of the present study is to develop such a tool and to verify its repeatability.</p> <p>Methods</p> <p>Instrumentation: At first we developed the Aesthetic Index (AI), based on a three-point scale for asymmetry of the shoulders, scapulae and waist that we tested for 5 years. From this experience we developed another tool we called TRACE, the acronym of Trunk Aesthetic Clinical Evaluation; TRACE is a 12-point scale based on four sub-scales, shoulders (0–3), scapulae (0–2), hemi-thorax (0–2) and waist (0–4).</p> <p>Population: Posterior-anterior (PA) photographs of one hundred-sixty AIS patients</p> <p>Procedures: Each photograph was scored in two independent tests by four observers using AI, and subsequently TRACE.</p> <p>Data analysis: Kappa statistical analysis and 95% level of agreement were used; we also identified the minimum significant change (95% confidence level).</p> <p>Results</p> <p>We found the intra- and inter-raters repeatability of AI to be fair. Three points out of seven was the minimum significant change between two different evaluations. For TRACE, intra-rater repeatability was fair and inter-raters poor; but the minimum significant change was three (intra-rater), or four (inter-raters) out of twelve points.</p> <p>Conclusion</p> <p>Widening the scale from 7 (AI) to 12 points (TRACE) increased the clinical sensitivity to changes of the aesthetic scale, even if TRACE has only a fair repeatability. TRACE is a no-cost tool for routine clinical practice in AIS patients. Due to the absence of other comparable validated tools, once the inherent measurement error is known and understood, its routine clinical use by physicians is advised.</p

How to improve aesthetics in patients with Adolescent Idiopathic Scoliosis (AIS): a SPoRT brace treatment according to SOSORT management criteria

<p>Abstract</p> <p>Background</p> <p>Aesthetics is a main goal of both conservative and surgical treatments in adolescent idiopathic scoliosis (AIS). Previously, we developed and validated a clinical scale - the Aesthetic Index (AI)--in order to measure aesthetic impairment and changes during treatment.</p> <p>Aim</p> <p>To verify the efficacy of bracing on aesthetics in AIS.</p> <p>Study Design</p> <p>Prospective Cohort Study.</p> <p>Population</p> <p>Thirty-four consecutive patients, age 13.2 ± 3.7, initial Cobb Angle 32 ± 12°, ATR 10 ± 4° Bunnel, 11 males.</p> <p>Methods</p> <p>Patients with AI scores of at least 5/6 were included. Each of them had a brace prescription (18 to 23 hours per day), according to the SPoRT concept. AI was measured again after six months and at the end of treatment, and then the pre- and post-treatment scores compared. The Wilcoxon test was performed.</p> <p>Results</p> <p>Twenty-nine patients out of the 34 included completed the treatment and had six-month and final results; four patients were lost during the treatment, and one was fused. At baseline, median AI was 6 (95% IC 5-6) but the score decreased to 3 (95% IC 0-5; p < 0.05) after six months with brace, and this value was maintained in the 29 who completed the treatment (95% IC 1-6; p < 0.05 with respect to the baseline).</p> <p>Conclusion</p> <p>Aesthetics can be improved in a clinically significant way when the brace treatment is performed according to the SPoRT concept and by following the SOSORT management criteria. This is a relevant result for patients and a major goal of scoliosis treatment, be it conservative or surgical. The use of a more sensitive tool like TRACE could more easily detect the clinical changes; nevertheless, AI proved sensible enough that its use in everyday clinical practice can be suggested.</p

Three-dimensional easy morphological (3-DEMO) classification of scoliosis, part I

BACKGROUND: While scoliosis has, for a long time, been defined as a three-dimensional (3D) deformity, morphological classifications are confined to the two dimensions of radiographic assessments. The actually existing 3-D classification proposals have been developed in research laboratories and appear difficult to be understood by clinicians. AIM OF THE STUDY: The aim of this study was to use the results of a 3D evaluation to obtain a simple and clinically oriented morphological classification (3-DEMO) that might make it possible to distinguish among different populations of scoliotic patients. METHOD: We used a large database of evaluations obtained through an optoelectronic system (AUSCAN) that gives a 3D reconstruction of the spine. The horizontal view was used, with a spinal reference system (Top View). An expert clinician evaluated the morphological reconstruction of 149 pathological spines in order to find parameters that could be used for classificatory ends. These were verified in a mathematical way and through computer simulations: some parameters had to be excluded. Pathological data were compared with those of 20 normal volunteers. RESULTS: We found three classificatory parameters, which are fully described and discussed in this paper: Direction, the angle between spinal pathological and normal AP axis; Shift, the co-ordinates of the barycentre of the Top View ; Phase, the parameter describing the spatial evolution of the curve. Using these parameters it was possible to distinguish normal and pathological spines, to classify our population and to differentiate scoliotic patients with identical AP classification but different 3D behaviors. CONCLUSION: The 3-DEMO classification offers a new and simple way of viewing the spine through an auxiliary plane using a spinal reference system. Further studies are currently under way to compare this new system with the existing 3-D classifications, to obtain it using everyday clinical and x-rays data, and to develop a triage for clinical use

Effectiveness of complete conservative treatment for adolescent idiopathic scoliosis (bracing and exercises) based on SOSORT management criteria: results according to the SRS criteria for bracing studies - SOSORT Award 2009 Winner

<p>Abstract</p> <p>Background</p> <p>The SRS criteria give the methodological reference framework for the presentation of bracing results, while the SOSORT criteria give the clinical reference framework for an appropriate bracing treatment. The two have not been combined in a study until now. Our aim was to verify the efficacy of a complete, conservative treatment of Adolescent Idiopathic Scoliosis (AIS)according to the best methodological and management criteria defined in the literature.</p> <p>Methods</p> <p>Study Design. Retrospective study. Population. We included all AIS patients respecting the SRS inclusion criteria (age 10 years or older; Risser test 0-2; Cobb degrees 25-40°; no prior treatment; less than one year post-menarchal) who had reached the end of treatment since our institute database start in 2003. Thus we had 44 females and four males, with an age of 12.8 ± 1.6 at the commencement of the study. Methods. According to individual needs, two patients have been treated with Risser casts followed by Lyon brace, 40 with Lyon or SPoRT braces (14 for 23 hours per day, 23 for 21 h/d, and seven for 18 h/d at start), and two with exercises only (1 male, 1 female): these were excluded from further analysis. Outcome criteria. SRS (unchanged; worsened 6° or more; over 45° at the end of treatment; surgically treated; two years' follow-up); clinical (ATR, Aesthetic Index, plumbline distances); radiographic (Cobb degrees); and ISICO (optimal; minimal). Statistics. Paired ANOVA and t-test, Tukey-Kramer and chi-square test.</p> <p>Results</p> <p>Median reported compliance during the 4.2 ± 1.4 treatment years was 90% (range 5-106%). No patient progressed beyond 45°, nor was any patient fused, and this remained true at the two-year follow-up for the 85% that reached it. Only two patients (4%) worsened, both with single thoracic curve, 25-30° Cobb and Risser 0 at the start. We found statistically significant reductions of the scoliosis curvatures (-7.1°): thoracic (-7.3°), thoracolumbar (-8.4°) and lumbar (-7.8°), but not double major. Statistically significant improvements have also been found for aesthetics and ATR.</p> <p>Conclusion</p> <p>Respecting also SOSORT management criteria and thus increasing compliance, the results of conservative treatment were much better than what had previously been reported in the literature using SRS criteria only.</p

Adult scoliosis can be reduced through specific SEAS exercises: a case report

<p>Abstract</p> <p>Background</p> <p>It has been known since many years that scoliosis can continue to progress after skeletal maturity: the rate of progression has shown to be linear, and it can be used to establish an individual prognosis. Once there is progression there is an indication for treatment: usually it is proposed a surgical one. There are very few papers on an alternative rehabilitation approach; since many years we propose specific SEAS exercises and the aim of this study is to present one case report on this approach.</p> <p>Case presentation</p> <p>All radiographs have been measured blindly twice using the same protractor by one expert physician whose repeatability error proved to be < 3° Cobb; the average measurement has been used. In this case a 25 years old female scoliosis patient, previously treated from 14 (Risser 1) to 19 years of age with a decrease of the curve from 46° to 37°, showed a progression of 10° Cobb in 6 years. The patient has then been treated with SEAS exercises only, and in one year progression has been reverted from 47° to 28.5°.</p> <p>Conclusion</p> <p>A scoliosis curve is made of different components: the structural bony and ligamentous components, and a postural one that counts up to 9° in children, while it has not been quantified in adults. This case shows that when adult scoliosis aggravates it is possible to intervene with specific exercises (SEAS) not just to get stability, but to recover last years collapse. The reduction of scoliotic curve through rehabilitation presumably does not indicate a reduction of the bone deformity, but rely on a recovery of the upright postural collapse. This reduction can decrease the chronic asymmetric load on the spine and, in the long run, reduce the risks of progression.</p

Specific exercises performed in the period of brace weaning can avoid loss of correction in Adolescent Idiopathic Scoliosis (AIS) patients: Winner of SOSORT's 2008 Award for Best Clinical Paper

<p>Abstract</p> <p>Background</p> <p>Exercises are frequently performed in order to improve the efficacy of bracing and avoid its collateral effects. Very frequently there is a loss of correction during brace weaning in AIS treatment.</p> <p>Aim</p> <p>To verify the efficacy of exercises in reducing correction loss during brace weaning.</p> <p>Study Design</p> <p>Retrospective controlled study.</p> <p>Population</p> <p>Sixty-eight consecutive patients (eight males), age 15 ± 1 and Cobb angle 22 ± 8° at start of brace weaning.</p> <p>Methods</p> <p>The start of brace weaning was defined as the first visit in which the wearing of brace for less than 18/24 hours was prescribed (according to our protocol, at Risser 3). Patients were divided into two groups according to whether or not exercises were performed: (1) EX (exercises), included 39 patients and was further divided into two sub-groups: SEAS (who performed exercises according to our institute's protocol, 14 patients) and OTH (other exercises, 25 patients) and (2) CON (controls, 29 patients) that was divided into two other sub-groups: DIS (discontinuous exercises, 19 patients) and NO (no exercises, 10 patients). Complete brace weaning was defined as the first visit in which the brace was no longer prescribed (ringapophysis closure or Risser 5, according to our protocol).</p> <p>ANOVA and Chi Square tests were performed.</p> <p>Results</p> <p>There was no difference between groups at baseline. However, at the end of treatment, 2.7 years after the start of the weaning process, Cobb angle increased significantly in both the DIS and NO groups (3.9° and 3.1° Cobb, respectively). The SEAS and OTH groups did not change. Comparing single groups, OTH (with respect to DIS) had a significant difference (P < 0.05).</p> <p>Conclusion</p> <p>Exercises can help reduce the correction loss in brace weaning for AIS.</p
