The use of CAD-CAM technology in the treatment of adolescent idiopathic scoliosis:
• The following is an introduction to a third CAD- CAM assisted approach developed by Dr. Miguel Gomez, of Bogotá, Colombia.
In introducing his approach, it is important to underscore that CAD-CAM should be seen as a single tool within the process and that the effectiveness of the bracing system is mostly dependent upon the experience and attention to detail on the part of the treating clinicians. Many of the principles introduced came from Dr. Gomez’s two decades of experience treating spinal deformities by traditional methods of hand casting and hand model rectification. However, the ability to apply these principles in a consistent, reproducible manner has been enhanced by the CAD technology.
• Inputs
Optimal use of a CAD-CAM based system requires multiple inputs. Each treatment plan begins with a careful evaluation of the patient’s deformity and in the coronal, sagittal and transverse planes documented by digital photography.
• Patient Measurements
As part of the clinical evaluation, over 25 anthropometric measurements are taken that include lengths, MLs, APs and circumferences as well as the geometry in all 3 planes.
• Flexibility
Flexibility of the spinal column is difficult to quantify, but important in predicting and ensuring maximal in-brace correction for each case.
