This is a preliminary study involving a relatively low number of patients. That said, given the fact that numerous parameters are connected with the age and height of the subjects, assessment with an isokinetic dynamometer can be constructively carried out from the age of 14. In order to further enhance understanding of this phenomenon, a longitudinal and comparative study of a larger group is needed.
BackgroundQuality of Life (QoL) scales have to be introduced in the treatment evaluation of our patients with adolescent idiopathic scoliosis.Vasiliadis et. al. created the Brace Questionnaire (BrQ), which is specific for brace-treated adolescents. This tool was developed and validated in Greek.The aim of our study was to undertake the process of cultural adaptation of the Brace Questionnaire (BrQ) into French.MethodsThe BrQ is made of 34 items on Likert scale, divided in eight domains. The questionnaire was developed for self-completion by the children and is adapted for 9 to 18-year-old patients.The process of cultural adaptation of the questionnaire was in accordance with the International Quality of Life Assessment (IQOLA) guidelines.In the first place, descriptive statistics were used to calculate mean scores and standard deviations for a given question and a domain. The second level was comparative, concerning reliability and validity.ResultsThe internal consistency was satisfactory; Cronbach’s alpha coefficient was 0.85. There were no floor or ceiling effects.ConclusionsThe French version of the BrQ (F-BrQ) is reliable and reproducible, and can therefore be used to evaluate the quality of life of children and adolescents treated with a brace for idiopathic scoliosis.Electronic supplementary materialThe online version of this article (doi:10.1186/s13013-017-0126-y) contains supplementary material, which is available to authorized users.
BackgroundScoliosis is a 3D deformity that can be reconstructed through 2D antero-posterior and lateral radiographs, which provide an upper view of the deformed spine as well as regional planes matching all vertebrae of elective plane for each curve. The objective of this study is to explore whether all idiopathic scoliosis classified Lenke 1A have the same 3D representation made with regional planes.MethodsAll patients treated for idiopathic thoracic scoliosis during the growth period and classified Lenke 1A were included in this study conducted in the pediatric spinal orthopedic department of Centre des Massues. A photogrammetric technique was used to obtain a 3D reconstruction, from regional planes identified on radiographs made with the EOS system. Three regional planes are usually identified in asymptomatic spines: lumbar, dorsal, and cervical—none of them presenting rotation. In the studied group, the number of planes, the rotation, and the limit vertebrae of each plane were looked for.ResultsSixty-three patients were included (47 girls and 16 boys, mean age 11.3 years). The Cobb angle was meanly 36.5°. The scoliosis was reconstructed with three regional planes (57%) or four ones (43%, with the thoracic plane divided into two planes). Maximal rotation was found in the thoracic plane, especially when scoliosis was represented with four regional planes. The transition between planes 2 and 3 was mainly located between the fourth and sixth dorsal vertebrae.ConclusionThe use of an arbitrary regional plane representation of a 3D shape leads to conclude that there are two types of Lenke 1A scoliosis, which should be taken into account for designing the brace.
The use of the carbon brace and of the Lyon brace induces a reduction in QoL whatever the evaluation tool, either SRS-22 or VAS. However, the use of the Lyon brace impairs QoL more than the use of the carbon brace.
Adolescents with cerebral palsy (CP) who walk or ambulate often have an abnormal clinical and radiological spinal profile during pubertal growth compared with adolescents of the same age without neuromotor impairments. Therefore, in the following study, we aimed to conduct a radiological assessment of static data on the lumbar-pelvic-femoral complex in ambulatory children with CP to compare these data with those of an asymptomatic population. The CP population was comprised of 119 children and the asymptomatic population was comprised of 652 children. The large format (30×90cm) sagittal X-rays were taken while subjects were in a comfortable position in which knees and hips were in maximal extension. Analyses were performed using Optispine(®) software to measure the parameters of an X-ray of the profile of the spine, pelvis and femurs. Comparing, the two populations, we found no difference in the shape parameter (pelvic incidence) but we did find significant differences in the positional parameters (pelvic tilt and sacral slope) of the pelvis. We found a difference in the curvature and orientation of lumbar lordosis as well as in the number of vertebrae involved in the kyphosis and its orientation. There was also a significant difference in the C7 plumb line. We can say that the CP population is not structurally different from the control population, but that parameters become disturbed during growth. These disturbances should be identified and monitored so that changes can be detected early and progression can be prevented.
