Abstract
Introduction
The distortion of the anatomy in some spine pathologies such as severe scoliosis and tumors, make the surgery a complex event, and the planning plays an important role. The image study interpretation in this kind of cases is difficult.
Methods
Biomodelism provides a better understanding of the anatomy and the surgical plan. Two models performed before the surgery of a complex spine deformity, we obtain DICOM images with a CT scan with reconstruction of 64 slides, 1 mm of thickness, and an interval of 1 mm and a reconstruction was done, the data were transferred to a stereolithographic format to print the model. The model was used to plan the surgery, check the trajectory of the pedicular screw, the approach, and the education of the family. The model was sterilized before and used as a tactile guide in the surgery.
Results
Before the surgery, the family and the patients understand the surgical procedure, the surgical team could evaluate the anatomy to understand the pathology. During the surgery, the model serves as a guide to realize the approach and the screw placement in a simple and systematized manner according to the surgery plan, and helps to evaluate the event after the surgery.
Discussion
D'Urso et al got a huge experience with biomodelism, we believe that the result in they work like in our work bring satisfactory results before, in the surgery and after the surgery, in the planning and the development of the procedure, as well as the postoperative evaluation with the use on the plastic model.
Conclusion
The use of biomodeling should be a frequent tool in spine complex cases where the anatomy could be affected.
