3D-Printed Plastic Cast Heal Broken Bones Faster

3D-Printed Plastic Cast Looks Awesome And Uses Ultrasound To Heal Broken Bones Faster

Designer Deniz Karasahin has created a prototype for a new kind of cast called ďOsteoidĒ that will hopefully help revolutionize the treatment of broken bones. His 3D-printed cast is stylish and more effective than the currently ubiquitous plaster casts we all know and dread.

The castís slick look isnít just eye candy Ė the holes prevent the cast from becoming excessively stinky or itchy, which is a common problem with big, heavy and non-breathable plaster casts. Its plastic construction means that it itself is waterproof but that it will also allow the patientís skin to breathe.

The castís production process seems like itís right out of a sci-fi movie. First, a 3D scan is done of the patientís arm. Then, modeling software generates a cast and creates holes. All of this is transferred to a program that finally allows a 3D printer to create the cast.

The cast also has an ultrasound system called LIPUS (Low-Intensity Pulsed Ultrasound System), which greatly increases the healing speed of broken bones. This system couldnít be used in plaster casts because of their composition, but it can be freely incorporated into these 3D-printed casts.

Perhaps most important of all, however, is that the cast can come in any color that plastic can be printed in. So while you wonít be able to get your cast signed anymore, you may actually end up looking stylish when wearing it.

6 Serious Medical Symptoms You Shouldn't Ignore E-mail
(2 votes)
Some medical symptoms are warnings that you need immediate care. Learn to recognize these six.

1. Paralysis of the arms or legs, tingling, numbness, confusion, dizziness, double vision, slurred speech, trouble finding words, or weakness, especially on one side of the face or body.

These are signs of stroke -- or a "brain attack" -- in which arteries that supply oxygen to the brain become blocked or rupture, causing brain tissue to die.

Symptoms depend on which area of the brain is involved. If a large blood vessel is blocked, a wide area may be affected, so a person may have paralysis on one side of the body and lose other functions, such as speech and understanding. If a smaller vessel is blocked, paralysis may remain limited to an arm or leg.

If you have symptoms, call 911 right away and get to an emergency room that offers clot-busting therapy for strokes due to blocked vessels. Such treatment, which dissolves clots in blocked vessels, needs to be given within the first three hours after symptoms begin, but newer treatments may work within a longer time frame, says Birge, who is medical director at the Tanner Medical Center in Carrollton, Ga.

Timing is urgent; fast treatment can potentially stop brain tissue death before permanent brain injury happens. "There is a time clock ticking as to when you might totally recover," Birge tells WebMD.
