| Popis: |
Scoliosis is a three-dimensional deformity of spine and surgical treatment is recommended when the spinal curvature is severe. Supine bending radiographs are usually taken prior to scoliosis surgery to measure the curve flexibility. However the ionizing radiation is a big concern to the patients and their families. The objective of this study was to determine the accuracy of the curve flexibility measurements on the ultrasound images. In this study, two surgical cases on children who have adolescent idiopathic scoliosis were reported. Both radiographs and ultrasound scans were acquired in standing and laying down bending positions. A total of 4 measurements were compared between the ultrasonic and radiographic methods. The average difference and standard deviation of the curve flexibility measurements (correction angles) between the two methods was 3.3±0.8°. This result demonstrated that the curve flexibility estimated by the US method was comparable to the results from radiography. However, since the number of participants is small, more trials are required before making a definite conclusion. |
