The custom orthosis is made through 3D scanning of the limb that needs to be immobilized or from the contra-lateral limb. The registered image is sent to a software where the orthosis model is applied to the specific anatomy obtained by the scan. The 3D image of the limb is subtracted and the final result is the customized orthosis ready to be sent for 3D printing.
The use of the customized and personalized orthosis directly impacts in less inconvenience when compared to other types of immobilizations such as those made with orthopedic plaster, for example.
Hygiene actions without removing this orthosis is also a considerable advantage. The patient can bathe with it and dry it with a hair dryer, for example, without the need to wrap the area with plastic or pvc film and also not depend on someone else to assist him.
This possibility allows avoidance of odors from perspiration and permits better monitoring of skin lesions without the need to change the immobilization.
And what are the advantages of 3D printing and softwares for building orthoses? The software allows 3D modeling of the orthosis, applying material only at the places necessary to block the joint movement involved, as well as the removal of material in locations it is not needed. This process makes the orthosis lighter, without compromising its efficiency. 3D printing also enables the use of recyclable polymers such as PET, PLA and Nylon in the production of customized and personalized orthoses without the need for large-scale production and storage. These factors allow production on demand without the need to stock the product and directly contribute to cost optimization, as well as reducing the weight of hospital waste when compared to plastered immobilizations.
