3dp_AdditiveOrthopaedics_jointsA hammertoe is a deformity of the foot that typically presents in the second, third or fourth toe as an overly bent toe that looks similar in shape to a hammer. It is caused by the joints becoming deformed by being bent for very long periods of time, which causes the muscles to shorten. It is usually caused by wearing shoes that are too small or too narrow, or by wearing extremely high heels that force the foot into a very unnatural shape, though hammertoe can also be caused by conditions as varied as diabetes, osteoarthritis, rheumatoid arthritis or even a stroke. It can be an extremely painful condition that can inhibit a patient’s ability to walk, and lead to other painful foot issues.

For very mild cases of hammertoe, doctors usually send the patient to physical therapy and suggest replacing any tight shoes with new shoes that have very soft insoles and are roomy enough for the toes to be able to fully extend. Any prescribed physical therapy usually consists of a series of foot and joint exercises that can help reshape the toe and prevent the condition from worsening. Doctors and physical therapists have also developed special braces that force the toe back into the correct shape, but these can be very painful to wear depending on the severity of the deformity, and they don’t always work.

Additive Orthopaedics LogoMany cases of hammertoe need to be corrected with podiatric surgery that involves surgically reshaping the afflicted toes. In fact more than 1 million people in the United States end up having to have a surgical procedure to correct their hammertoe each year. As with any surgery on the foot, this can often cause a great deal of pain, take weeks of recuperation in order to be fully mobile again and is no guarantee of it permanently solving the problem. But Additive Orthopaedics, a Little Silver, New Jersey-based early stage orthopedic extremity device manufacturer and developer has announced that they have successfully treated a series of patients who were diagnosed with hammertoe using a new 3D printed hammertoe implant.

“Our implant has properties and features only possible through the additive manufacturing process. We are confident that the market will respond well to this, our patient specific products in development, and our other devices currently being reviewed by the FDA,” said the President and Founder of Additive Orthopaedics, Greg Kowalczyk.

3dp_AdditiveOrthopaedics_hammertoe_xrayAdditive Orthopaedics developed their 3D printed corrective implant to be faster to manufacture, custom made for the patient’s foot and to improve the chances of the condition being successfully corrected. After the successful testing of the implant, the FDA cleared the hammertoe implant, making it available to doctors all over the country. The young startup has already raised enough seed money to close their first round and develop the hammertoe implant. Among their investors is Asimov Ventures. After the successful tests, Additive Orthopaedics is readying themselves to open up a second round of financing to help them take their new product to market. They are also in the process of developing and gaining approval for new corrective implants for similar conditions like mallet toe or claw toe.
