A new optical scanning method is applyed for a static and dynamic analysis of thorax and spine deformities in brace and surgically treated scoliosis patients to capture intervention dependent changes over time. The costs and additional information captured by the method is analysed.
To evaluate the intervention dependent changes in spine and chest wall deformities, such as mobility of thorax, volume, symmetry of growth, and possible growth distorting factors are poorly known and should be studied. In patients with neuropathic spine deformities, the seat loading is of importance to enhance balanced sitting and preventing pressure problems. Quantitative methods to be used for over time comparisons need to be further developed.
In adolescents the decision to treat a spine deformity is mainly based on radiographic findings, whereas many patients are more interested in how their body configuration deviates from the normality. There is a need to implement and evaluate a method for this purpose. In brace treated children and adolescents, a non-radiation producing examination is to prefer for repeated follow-up controls.
A consequtive series of children with spine deformity, who are enrolled in the treatment protocol, are invited to take part in the tests. In surgery group, tests are performed before and 3 months after surgery aimed to correct the spine and/or thorax deformity. In brace treatment and follow-up groups tests are made at the same time points as x-rays. The static and dynamic recordings are performed by and optic scanenr Artec 3D (Artec Group, San Diego, CA), and
the sitting load distribution measurements with a sensor mat (Clin-seat Type 5315 by Tekscan,
Boston, Massachusetts, USA). 60 children/year in brace treatment, 40 in surgery, and 50 in the
follow-up group are estimated to be included. These methods´ costs and benefits as well as
their added value for the clinical decision making will be evaluated after 2-3 years.
A feasibility test shows that clinically small enough differences can be recorded and numerically expressed and analysed. An application on a consecutive, clinical patient group will be carried on.
The optical scanning method by Artec, allows a static and dynamic capturing of respiratoryassociated thorax movements and the changes of a spine deformity over time. The new method will be applied in a consecutive series of patients.
