  • Stress level in adolescents wearing corrective brace for idiopathic scoliosis: study with BSSQ questionnaires
    Scoliosis, 2015
    Co-Authors: Edyta Kinel, Anna Podolska-piechocka, Magdalena Sobieska, Tomasz Kotwicki
    Abstract:

    Material and methods The study involved 80 adolescents (71 girls and 9 boys), fulfilling the inclusion criteria: age range between 11.0 and 16.0 years, Cobb angle range between 20 and 45 degrees, wearing Cheneau orthosis for more than 3 months, at least 12 hours per day. The group was analyzed in subgroups according to (1) age: 11.0-13.0 years (n=40) versus 14.016.0 years (n=40), (2) brace wearing time: less than 20h (n=45) versus more than 20h per day (n=35), (3) place of residence: village (n= 34), town (n= 20) or city (n= 26). Maximal angle of trunk rotation (ATR max) was measured using Bunnell Scoliometer. Bad Sobernheim Stress Questionnaires (BSSQ), both the Brace and the Deformity versions were used, the former estimates the stress the patients have whilst wearing brace, the latter estimates the stress induced with body deformation.

  • School screening for scoliosis: can surface topography replace examination with Scoliometer?
    Scoliosis, 2012
    Co-Authors: Joanna Chowanska, Tomasz Kotwicki, Krzysztof Rosadzinski, Zbigniew Sliwinski
    Abstract:

    Background Clinical examination with the use of Scoliometer is a basic method for scoliosis detection in school screening programs. Surface topography (ST) enables three-dimensional back assessment, however it has not been adopted for the purpose of scoliosis screening yet. The purpose of this study was to assess the usefulness of ST for scoliosis screening. Methods 996 girls aged 9 to 13 years were examined, with both Scoliometer and surface topography. The Surface Trunk Rotation (STR) was introduced and defined as a parameter allowing comparison with Scoliometer Angle of Trunk Rotation taken as reference. Results Intra-observer error for STR parameter was 1.9°, inter-observer error was 0.8°. Sensitivity and specificity of ST were not satisfactory, the screening cut-off value of the surface topography parameter could not be established. Conclusions The study did not reveal advantage of ST as a scoliosis screening method in comparison to clinical examination with the use of the Scoliometer.

  • Position-dependent trunk asymmetry assessed with Scoliometer
    Scoliosis, 2012
    Co-Authors: Joanna Chowanska, Tomasz Kotwicki, Krzysztof Rosadzinski
    Abstract:

    Materials and methods The study comprised 996 girls, aged 9 to 13, mean 11.0 ± 1.0 years of age. ATI measurements were performed at three levels of the spine: proximal thoracic, main thoracic and thoracolumbar/lumbar. Maximal ATI values for standing and sitting forward bending positions were noted. Based on the ‘7°’ criterion, the number of children who need follow up was revealed, according to position: (a) standing, (b) sitting, (c) any of standing or sitting, (d) either standing or sitting.

  • Trunk asymmetry in one thousand school children aged 7-10 years.
    Studies in health technology and informatics, 2012
    Co-Authors: Lukasz Stolinski, Tomasz Kotwicki
    Abstract:

    Screening for idiopathic scoliosis is not very popular in Poland. Some Polish towns and cities have prevention programmes aimed at discovering spine dysfunctions and disorders in children and adolescents. An assessment of the angle of trunk rotation (ATR) is a reliable, effective and non-invasive action that allows use to determine trunk asymmetry. Since then the Scoliometer has spread throughout the United States and other countries, where it is a popular device in the clinical practice of diagnosing scoliosis. 9,500 children aged 7-10 were examined as part of a disease prevention programme entitled "Poznan Chooses Health - Bad Posture Prophylaxis in Class I-IV Primary School Children in Poznan". The analysis included results obtained in 2010 during initial posture assessment in 1000 children, Trunk asymmetry was measured by means of the Bunnell Scoliometer. The measurement of the angle of trunk rotation was the spontaneous standing position with use the Scoliometer during bending (Adams forward test) at three levels: proximal thoracic, main thoracic and lumbar. For the proximal thoracic section the 0° ATR value was found in 6 children, values of 1°-3° were recorded in 883 children, values of 4°-6° in 108 children, 7° or higher in 3 of the examined children. For the main thoracic section the 0° ATR value was found in 101 children, values of 1°-3° were recorded in 735 children, 4°-6° in 155 children, 7° or higher in 9 of the examined children. For the lumbar section ATR values of 0°, 1°-3°, 4°-6°, and 7° or higher were found, respectively, in 147, 883, 108 and 11 of the examined children.

  • The Relationship Between Apical Vertebral Rotation and Truncal Rotation in Adolescent Idiopathic Scoliosis Using 3D Reconstructions
    Spine Deformity, 2018
    Co-Authors: Pawel P. Jankowski, Tracey P. Bastrom, Burt Yaszay, Krishna R. Cidambi, Carrie E. Bartley, Peter O. Newton
    Abstract:

    Study Design Retrospective review of prospective data. Objectives To evaluate the relationship between absolute apical vertebral rotation (AVR) evaluated with upright 3D imaging and angle of trunk rotation (ATR) before and after surgery for thoracic and lumbar curves in adolescent idiopathic scoliosis (AIS). Summary of Background Data New imaging technology allows for improved radiographic assessment of the degree of AVR pre- and postoperatively through 3D spine models created from biplanar, simultaneous spine radiographs. Methods A prospective registry was queried and identified 55 AIS patients with major thoracic or major thoracolumbar/lumbar curves who underwent posterior spinal fusion. All patients had biplanar upright imaging of their spine and ATR measurements assessed via Scoliometer pre- and postoperatively. Results There were 33 major thoracic and 22 major lumbar curves. The mean Cobb angles for thoracic and thoracolumbar/lumbar curves were 54° ± 10° and 47° ± 8° preoperatively, and 11 ± 6° and 12 ± 7° postoperatively. The differences in the mean preoperative ATR measurements for both major curve types was not statistically significant; however, the difference in AVR between thoracic curves (13 ± 6°) and lumbar curves (22 ± 7°) was significant (p < .001). There was a significant decrease in the ATR and AVR for both thoracic and thoracolumbar/lumbar curves (p < .001) postoperatively. A significant correlation between ATR and AVR was found only for the major thoracolumbar/lumbar curves (p < .001). The relationship between ATR and AVR changes for both curves was not statistically significant. Conclusion ATR measured via Scoliometer strongly correlates with 3D measurements of AVR in both thoracic and lumbar curves before and after surgery for AIS. No significant relationship was found between the changes in ATR and AVR due to surgery. Postoperatively, greater clinical rotational deformity remains in the thoracic spine compared to the lumbar spine, despite greater apical vertebra axial plane correction in thoracic curves. Level of Evidence Level II, diagnostic.

  • Recurrence of rib prominence following surgery for adolescent idiopathic scoliosis with pedicle screws and direct vertebral body derotation.
    European spine journal : official publication of the European Spine Society the European Spinal Deformity Society and the European Section of the Cerv, 2014
    Co-Authors: Amer F. Samdani, Jahangir Asghar, Firoz Miyanji, James T. Bennett, Jane S. Hoashi, S. Lonner, Michelle C. Marks, Peter O. Newton, Randal R. Betz
    Abstract:

    Pedicle screw constructs combined with direct vertebral body derotation (DVBD) provide a powerful corrective force of the rib prominence associated with adolescent idiopathic scoliosis (AIS). We wished to evaluate the incidence and correlative factors associated with recurrence of rib prominence (RRP) developing postoperatively despite adequate initial correction. 103 patients with AIS underwent pedicle screw fixation with DVBD without thoracoplasty and had postoperative Scoliometer readings at 6, 12, and 24 months. Patients with RRP, defined as a postoperative Scoliometer increase ≥5°, were compared to those without recurrence. The mean rib prominence measured 14.0 ± 4.3° preoperatively, with a correction of 50.3 ± 26.7 % at 6 months, 49.0 ± 39.0 % at 1 year, and 49.1 ± 26.7 % at 2 years. RRP was identified in 15.5 % of the patients with a correction of 57.5 ± 25.5 % at 6 months, 47.2 ± 42.5 % at 1 year, and 40.4 ± 21.6 % at 2 years. At 2 years, the RRP group demonstrated a significantly larger major coronal Cobb (p

  • Comparison of compensatory curve spontaneous derotation after selective thoracic or lumbar fusions in adolescent idiopathic scoliosis.
    Spine, 2008
    Co-Authors: Todd F. Ritzman, S. Lonner, Randal R. Betz, Vidyadhar V. Upasani, Tracey P. Bastrom, Peter O. Newton
    Abstract:

    STUDY DESIGN Retrospective review of a multicenter prospectively collected series of adolescent idiopathic scoliosis (AIS) patients. OBJECTIVE To compare uninstrumented compensatory curve spontaneous derotation of the rib hump and lumbar prominence after selective lumbar or thoracic fusions in AIS. SUMMARY OF BACKGROUND DATA Coronal correction of the unfused minor curve after selective fusions in AIS has been well-documented previously. However, little has been reported regarding spontaneous correction in the axial plane of the unfused minor curve after selective AIS surgery. METHODS Patients with minimum 2-year follow-up after either a selective thoracic fusion (STF) (lowest instrumented vertebrae L2 or above), or a selective lumbar fusion (upper instrumented vertebrae T9 or below) for AIS, with an initial Scoliometer value of >or=5 degrees in the minor curve were analyzed. Prospectively acquired preoperative and 2-year postoperative radiographic and Scoliometer measurements of both the fused and unfused curves were compared using repeated measures and univariate analysis of variance. The data were checked for normality and equal variances, and the level of significance was set at P

  • Using the Scoliometer and a Surface Topography Apparatus to Check if Back Trunk Asymmetry Changes in Children and Adolescents in the Forward Flexion and Standing Erect Positions.
    Cureus, 2019
    Co-Authors: Emmanouil G Maragkoudakis, Theodoros B Grivas, Christina Mazioti, Ioannis Gelalis, Geofrey R Burwell, Gerasimos Tsilimidos
    Abstract:

    Background The purpose of this study is to evaluate the effects of the forward bending (FB) test versus the standing erect (SE) position on back trunk asymmetry (TA). The Scoliometer in the FB position and the 4D Formetric (4DF; Diers International, Schlangenbad, Germany) readings in the SE position were assessed. Method The angle of trunk inclination (ATI) was measured at the midthoracic, thoracolumbar, and lumbar levels using the Scoliometer in the FB position and the 4DF in the SE position. A total of 134 subjects attending the scoliosis clinic (86 girls and 48 boys), age ranging from seven to 18 years, were assessed. The children and adolescents were divided into three groups according to the severity of TA, symmetric group 1 (0-2 degrees), asymmetry group 2 (2 to 6 degrees), and group 3 having asymmetry of seven or more degrees. Children with leg length discrepancy were excluded from the study. The IBM SPSS v.20 package (IBM Corp., Armonk, NY) was used for analysis. Results At the midthoracic level comparing the Scoliometer to 4DF readings in males in group 1, the Wilcoxon signed ranks test was p=0.451 while for the Spearman’s Rho, it was -0.138; in group 2, p=0.184 and Rho=0.204; and in group 3, p=0.109 and Rho=0.500. For females in group 1, p=0.000 while Rho=0.003; in group 2, p=0.008 and Rho=0.000, and in group 3, p=0.003 while Rho=0.642. At the thoracolumbar level in males for group 1, p=0.004 and Rho=-0.517; in group 2, p=0.006 and Rho=0.000; and in group 3, p=0.043 while Spearman’s Rho=0.053. For females in group 1, p=0.000 and Rho=-0.095; in group 2, p=0.000 and Rho=-0.171; in group 3, p=0.001 while Rho= -0.081. At the lumbar level for males in group 1 p=0.000 while Rho=0.149; in group 2, p=0.003 and Rho=0.373; while in group 3, p=0.109 and Rho= (-). For females in group 1, p=0.000 while Rho=-0.072; in group 2, p=0.001 and Rho=0.168; and in group 3, p=0.068 while Rho=0.500. Conclusion The results of this study show that the back TA in children and adolescents is not similar in the FB and SE positions. This phenomenon probably is attributed to the complicated trunkal (spinal, thoracic, and pelvic) anatomy, and the results of this study may be used as a useful foundation for further understanding of torso dynamics.

  • Truncal asymmetry in school children: the effect of the parental age at birth
    Scoliosis, 2013
    Co-Authors: Theodoros B Grivas, Constantinos Mihas, Christina Mazioti, S Sakellaropoulou, N Zisis, Antonios Akriotis, R.g. Burwell
    Abstract:

    Methods 11,832 (5,855 males, 5,977 females) children and adolescents (5-17 years old, mean age: 11.34±2.79) were screened at their school for TBSA and/or scoliosis. The Prujis Scoliometer was used to examine the students in standing, and sitting, forward bending positions. If at least one of the child’s measured angles was equal to or exceeded 6 or 7 degrees of Scoliometer reading, it was labelled as “Asymmetry 6” and “Asymmetry 7” respectively. The age, standing height and body weight of the children and the parental age were also documented. The parental age at birth and children’s BMI were subsequently calculated. Asymmetries were tested for correlation with parental age at birth, which was transformed to a categorical variable in 5-year intervals. Pearson’s Chi-squared test for univariate and logistic regression for quantitative univariate and multivariate analysis were used. The SPSS and STATA v. 11.0 statistical packages were used.

  • Study of body mass (BMI) index and truncal asymmetry (TA) in healthy adolescents
    Scoliosis, 2009
    Co-Authors: Theodoros B Grivas, R.g. Burwell, Elias Vasiliadis, Constantinos Mihas, Georgios Triantafyllopoulos, Angelos Kaspiris
    Abstract:

    A group of 5953 adolescents, ages 11-17 years (2939 boysand 3014 girls) were examined in a school screening pro-gram using two standard positions: standing forwardbending (FB) and seated forward bending. TA was evalu-ated in both positions using a Pruijs Scoliometer whichmeasured the angle of trunk inclinations (ATIs) across theback at each of three regions: thoracic, thoracolumbar andlumbar. An abnormal ATI was defined as being beyond 2standard deviations from the mean for region, age, genderand position, and this was termed severe TA. Each childwas assigned to a relatively lower or relatively higher BMIgroup using a median value of BMI by age and sex. The sit-ting FB position is thought to express intrinsic TA freefrom extrinsically-induced effects of any leg-length ine-quality.

    Co-Authors: Theodoros B Grivas, Elias Vasiliadis, Constantinos Mihas, Christina Maziotou, Georgios Triantafyllopoulos, Panagiotis Alexandropoulos
    Abstract:

    MATERIAL AND METHOD: The Scoliometer readings in both standing and sitting forward bending position (FBP) of 3301 children, (1645 boys, 1656 girls) aged from 3 to 9 years old, were studied. TA was quantified by measuring angle of trunk rotation (ATR) and children were divided in two groups. In group I the ATR was 1AE to 6AE degrees and in group II ≥7AE. STATA 9.0 statistical package was used for the analysis.

  • How much does the Dynamic Derotation Brace affect the surface deformity of children with idiopathic scoliosis
    Scoliosis, 2007
    Co-Authors: Theodoros B Grivas, Elias Vasiliadis, Georgios Triantafyllopoulos, Georgios Koufopoulos, Vasilios Mouzakis
    Abstract:

    Methods Thirty-six scoliotic children (32 female, 4 male) with a mean age of 13.9 years (range 12–17 years), a mean Cobb angle of 28.2 degrees (range 19–38) and a mean angle of trunk inclination (ATI) of 7.8 degrees (range 4–17) were included in the study. The examined children were divided in three subgroups according to the curve type. All the children were treated with the DDB with antirotatory blades and they wore the brace for twenty-three hours per day for a minimum duration of two years. The ATI was assessed using the Pruijs Scoliometer [2] during the first examination and during the follow up, with the children out of the brace.
