Cast Aside Bathing Difficulties With 3D Printing

Question: I found your article, “Here’s How 3D-Printed Models Can Help Explain Conditions, Aid Mock Surgeries, and Predict Treatment Outcomes” in Tech and Innovation in Healthcare, Volume 1, Issue 5 fascinating, and would love to hear about other uses of 3D printing in healthcare.

Answer: While there are many uses for 3D printing in healthcare, here’s the scoop on one up-and-coming use.

Specialists in the Department of Physical Medicine and Rehabilitation at the Mayo Clinic in Florida have developed 3D-printed casts to help make healing more hygienic. Traditional fiberglass casts need to stay dry, which can be difficult when the patient needs to bathe. However, the new 3D-printed casts and splints are made of a waterproof polymer material, which allows the patient to bathe, sweat, and do a variety of other physically active tasks.

Specialists perform a scan of the injured area, transform the scan into a digital model, and then bring the model to life. The entire process takes approximately 90 minutes.

Additionally, the polymer material is more durable than a traditional fiberglass cast. The material disperses forces evenly across the surface, whereas a fiberglass cast transmits an impact force to the bone.

As of March 2022, the ideal candidates for the 3D-printed casts are patients 10 years and older with traditional wrist fractures.
