Introduction
Spinal orthosis with good compliance is recommended treatment for idiopathic scoliosis. However, conventional orthosis in hot weather like Thailand is difficult. Some patients got bullied at school due to bulky appearance. 3D technology could help in these issues. However, the commercial CAD-CAM software is expensive for our country insurance( cover 235 USD /brace). Therefore, we developed the Hybrid technique to reduce the cost.
Objective
Study the efficacy of hybrid technique of spinal orthosis in idiopathic scoliosis.
Methods
Orthosis was made by using semi - Digital Fabrication to adjust and correct the alignment of the spine. Plaster cast was molded around the patient and correct the alignment using modified cheneau brace. Then we use 3D Ipad scanner to scan the molded cast and using free software program to create and design the spinal brace for 3D printed, made from nylon filament. The design was created to make it ventilated and thin as much as possible while still maintain biomechanics correction.
Results
A 14 years old girl with scoliosis cobb angle (apex T10) at 20 degrees progress to 32 degrees , due to poor compliance. Our orthosis could reduce the angle to 18 degrees. After one year, the angle could be reduced to 10 degrees. She used the brace until the age of 16, and the angle was less than 10 degrees at the end of treatment.
Conclusion
The hybrid method could help make 3D spinal orthosis for idiopathic scoliosis patient.
Statement of the objective / learning objectives
Using the hybrid method to make 3d scoliosis brace and save cost -effectiveness in low to middle income country
