DSM Dyneema and University hospital Maastricht collaborate to explore new solutions for correcting spinal deformities20-Jun-08

DSM Dyneema and the university hospital Maastricht (azM), The Netherlands, today announced a joint agreement to conduct research into new solutions that can improve surgical outcomes for patients with spinal deformities. Combining the materials technology of DSM Dyneema with the clinical expertise of the university, this project aims to develop new solutions that support the trend toward minimally invasive procedures as well as the need for preservation of mobility. The project team will focus on leveraging Dyneema Purity®, an Ultra High Molecular Weight Polyethylene fiber offering maximum strength and minimum weight, to enhance post-operative mobility and quality of life for surgery patients as a result. Furthermore, the high strength-to-weight ratio of Dyneema Purity® enables device miniaturization to support minimally invasive surgical techniques that promote faster recuperation and reduced scarring.

Dr. Lodewijk W. van Rhijn, orthopedic surgeon at the university hospital Maastricht, said, “The dynamic nature of cable constructions made with Dyneema Purity® enable preservation of mobility as well as fixation. This combination of properties opens-up numerous possibilities for improvements of surgical techniques and devices. The results of the project are expected to allow me to improve the patient’s quality of life”.

The research agreement has initially been set for one year. Both organizations have expressed willingness to continue the project over a longer term once the results in the first year support such continuation. Development of an actual prototype device will take several years.

Carina Snijder, business manager medial at DSM Dyneema, said, “Dyneema Purity® fiber offers tremendous potential to design the next generation of medical devices for less-invasive surgery. Its unique combination of strength, flexibility, light weight, and softness makes this fiber ideal for new approaches to the correction of spinal conditions. We look forward to a fruitful partnership to support improved outcomes for spinal surgery patients.”

Dyneema Purity® fiber is 15 times stronger than steel on a weight-for-weight basis. It provides a high level of stiffness and resistance to fatigue and abrasion. This material has successfully been independently tested for cytotoxicity, sensitization, irritation and mutagenicity.
