“…We have not found any correlation between BSSQDeformity, BSSQ-Brace, Cobb's angle, the degree of the apical translation of center sacral vertical line (CSVL) according to the Harms Study Group [11] and the duration of brace wearing per day and total number of months worn ( Table 7). The only statistically significant correlation (p = 0.19) was identified between BSSQ-Brace and the angle of rotation (rs 0.395).…”

Bad Sobernheim Stress Questionnaire-Brace and Bad Sobernheim Stress Questionnaire-Deformity are relatively new tools aimed at facilitating the evaluation of long-term results of therapy in persons with idiopathic scoliosis undergoing conservative treatment. To use these tools properly in Poland, they must be translated into Polish and adapted to the Polish cultural settings. The process of cultural adaptation of the questionnaires was compliant with the guidelines of International Quality of Life Assessment (IQOLA) Project. In the first stage, two independent translators converted the originals into Polish. Stage two, consisted of a comparison of the originals and two translated versions. During that stage, the team of two translators and authors of the project identified differences in those translations and created a combination of the two. In the third stage, two independent translators, who were native speakers of German, translated the adjusted version of the Polish translation into the language of the original document. At the last stage, a commission composed of: specialists in orthopedics, translators, a statistician and a psychologist reviewed all translations and drafted a prefinal version of the questionnaires. Thirty-five adolescent girls with idiopathic scoliosis who were treated with Cheneau brace were subjected to the questionnaire assessment. All patients were treated in an out-patient setting by a specialist in orthopedics at the Chair and Clinic of Orthopedics and Traumatology. Median age of patients was 14.8 SD 1.5, median value of the Cobb's angle was 27.8°SD 7.4. 48.6% of patients had thoracic scoliosis, 31.4% had thoracolumbar scoliosis, and 20% patients had lumbar scoliosis. Median results obtained by means of the Polish version of BSSQ-Brace and BSSQ-Deformity questionnaires were 17.9 SD 5.0 and 11.3 SD 4.7, respectively. Internal consistency of BSSQ-Brace and BSSQ-Deformity was at the level of 0.80 and 0.87, whereas the value of the absolute stability factor was 0.82 and 0.88. Overall, the Polish versions of the BSSQ-Brace and BSSQ-Deformity Questionnaires are characterized by high values of internal consistency factor and absolute stability factor. Following the process of adaptation, the authors obtained a tool that is instrumental in clinical evaluations and complies with methodological criteria.

“…This paper contains only radiographic data and it may be considered as a limitation since the radiographic result is mainly of interest to surgeons but of less importance to patients [33]. Still, there is no clear evidence that application of DVR benefits in terms of clinical outcome and patient's self-assessment [9]; thus, analysis of the clinical effect of DVR is required.…”

Introduction Recent developments of spinal instruments allow to address nearly all components of idiopathic scoliosis. Direct vertebral rotation (DVR) maneuver was introduced to correct apical axial vertebral rotation. It is however still not well established how efficiently DVR affects results of scoliosis correction. The object of the study was to evaluate en bloc apical vertebral rotation (DVR) and its impact on coronal and sagittal correction of the spine in patients undergoing surgical scoliosis treatment. Materials and methods Thirty-six consecutive patients who underwent posterior spinal fusion with pedicle screws only constructs for idiopathic scoliosis. Fifteen patients (20 curves) were corrected by rod derotation only and 21 patients (26 curves) had both rod derotation and DVR. Curve measurements were performed on x-rays obtained before and postoperatively-coronal curves, kyphosis (T2-T12, T5-T12). Spine flexibility was assessed on prone bending x-rays. Apical axial rotation was determined on CT scans obtained intraoperatively and postoperatively. Rotation angle (RAsag) was measured according to Aaro and Dahlborn. Results We observed reduction of RAsag in all patients; however, in DVR group, decrease was greater, by 31.8% comparing to non-DVR group, by 8.6% (p = 0.0003). Mean coronal correction in DVR group was 68.8% and in rod derotation group without DVR 55% (p = 0.002). No significant correlation was found between degree of derotation obtained and coronal correction. In DVR group T2-T12 kyphosis has increased in 28 (65%) patients whereas in non-DVR group in 31 (69%) cases. Mean value of T2-T12 kyphosis growth was 16.7% in DVR and 22.1% in non-DVR group. These differences however did not occur statistically significant. Conclusions Direct vertebral rotation (DVR) maneuver reduces significantly apical rotation of the spine, enhances ability of coronal correction, and it does not reduce thoracic kyphosis.

RESUMOObjetivo: Realizar avaliação clínica e radiográfica de pacientes com escoliose idiopática do adolescente (EIA) submetidos à artrodese por via posterior utilizando parafusos pediculares e correlacionar os resultados por imagem com os escores obtidos através do questionário SRS-24. Métodos: Foram avaliados 25 pacientes com diagnóstico de escoliose idiopática do adolescente, submetidos à artrodese da coluna por via posterior com parafusos pediculares. O seguimento médio foi de 23,7 meses, variando entre 12 e 35. Analisamos critérios radiográficos referentes à correção das deformidades e aplicamos o questionário SRS-24, específico para esta doença, padronizado pela Scoliosis Research Society. Resultados: A amostra foi composta por 92% de pacientes do gênero feminino e a média de idade foi de 14,2 anos. A média do índice de Cobb na radiografia ântero-posterior pré-operatória foi de 24,4° para curva torácica proximal, 54,9° para torácica principal e 38,5° para curva lombar. Os valores angulares médios no pós-operatório foram 11,0°; 16,7° e 12,2° respectivamente, com porcentagem de correção média da curva torácica principal de 69,9%. O valor médio final do questionário SRS-24 foi 98,1 pontos. Dois pacientes apresentaram complicações pós-operatórias, entretanto, nenhuma do tipo neurológica. Conclusão: A técnica se mostrou eficaz para tratamento cirúrgico da EIA, proporcionando alto percentual de correção das deformidades, com baixo risco de complicações e resultado clínico satisfatório. Não foi encontrada relação estatisticamente significante entre a porcentagem de correção da curva (torácica principal ou lombar) ou seu valor angular pós-operatório com o valor final do questionário SRS-24 nem com os domínios "satisfação" e "auto-imagem pós-operatória". RESUMENObjetivo: Evaluar clínica y radiográficamente a pacientes portadores de escoliosis idiopática del adolescente sometidos a artrodesis por vía posterior, utilizando solamente tornillos pediculares, y correlacionar el resultado radiográfico con los valores obtenidos a través del cuestionario SRS-24. Métodos: Fueron evaluados 25 pacientes portadores de escoliosis idiopáticas del adolescente, sometidos a artrodesis de la columna por vía posterior. El seguimiento promedio fue de 23,7 meses, con variación entre 12 y 35. Analizamos criterios radiográficos referentes a la corrección de las deformidades y aplicamos el cuestionario SRS-24, específico para la patología en cuestión, estandarizada por la Scoliosis Research Society. Resultados: La muestra fue compuesta por 92% de pacientes del sexo
