Three-dimensional reconstruction techniques are widely used to provide a spatial description of scoliotic spines. One example is the 3-D reconstruction method developed and routinely used at Sainte-Justine Hospital. It concerns the reconstruction of six anatomical landmarks per vertebra from the frontal and lateral radiographs: endplate centers; inferior and superior tips of both pedicles. Although this “standard” method is accurate, it requires 2 h for an expert technician to identify all anatomical landmarks on radiographs.Objective. – Therefore, this paper presents a novel and fast computed acquisition method providing a reconstruction of the spine better suited to the needs of the orthopedists during scoliosis clinics.Materials and Methods. – In this approach, five to eight points are identified on the frontal and lateral radiographs to obtain the overall shape of the spine. 2-D average predictive models, are built from a database of 791 radiographs, allowing to estimate the 2-D coordinates of the six vertebral landmarks and to obtain their 3-D coordinates from the DLT algorithm.Results and conclusions. – The evaluation of this “fast method” shows that the minimum number of points to be identified on the frontal radiograph is six for right thoracic or left lumbar curves and eight for right thoracic–left lumbar curves. Seven points need to be identified on the lateral radiograph. Furthermore, average models corresponding to a specific type and severity of scoliosis allow the 2-D mean differences between “standard” and “fast” methods to be less than 3.7 mm for endplate landmarks and 5.0 mm for pedicles. No significant difference was found between clinical indices obtained from both methods, confirming that the “fast” method is well adapted for direct clinical use. [Copyright &y& Elsevier]
