Correcting spinal deformities

Advances in Textiles Technology, August, 2008

DSM Dyneema and the University Hospital Maastricht (azM), The Netherlands, are to conduct joint research with the aim of improving the results of surgery on patients with spinal deformities.

Combining the materials technology of DSM Dyneema with the clinical expertise of the University, the project seeks to develop solutions that support the trend towards minimally invasive procedures, which promote faster recuperation and reduced scarring, as well as the need for preserving the patient's mobility.

The project team will focus on exploiting the ultra-high molecular weight polyethylene (UHMWPE) fibre Dyneema Purity[R]. This fibre is strong and low in weight, which allows for the miniaturization of any support device, an advantage for minimally invasive surgical techniques. It is also soft and so flexible.

An orthopaedic surgeon at the hospital, Lodewijk W. van Rhijn, 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 agreement has initially been set for one year, but both organizations have expressed willingness to continue once the results show promise. Development of an actual prototype device will take several years, they believe.

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