Julius Wolff Institut has won the prestigious award for a joint publication with the CMSC.

Marcel Dreischarf, PhD student at the Julius Wolff Institute and Berlin-Brandenburg School for Regenerative Therapies, has won the Clinical Biomechanics Award 2013 of the European Society of Biomechanics (ESB). The Award was presented to him at the 19th Congress of the ESB in Patras (Greece).

The awarded presentation has the title "Influence of a vertebral misalignment after total disc replacement on facet joint forces, capsule tensile forces and clinical outcome" and is a jointly research work with his colleagues Antonius Rohlmann, Sascha Lauterborn, Hendrik Schmidt and Thomas Zander and Michael Putzier and Patrick Strube from the Center of Musculoskeletal Surgery of the Charité.

The clinical success of artificial discs is often good. However, in some patients the range of motion at the index level is reduced and the facet joints are degenerated as early as two years after surgery. The implantation of an artificial disc may result in a small misalignment of the vertebrae adjacent to the implant. In the awarded presentation, the effect of such a misalignment on the mechanical behavior of the spine was investigated in a numerical simulation. It was found that a misalignment reduces the range of motion and, depending on the direction, increases the contact facet joint forces or the tensile forces in the joint capsule.

In a subsequent clinical study it could be shown, that the clinical results are worse when the misalignment caused higher tensile forces in the capsule. The manufacturers are appealed to provide surgical tools that allow a precise implantation of an artificial disc.

After 2000 and 2008 it is already the third time that a member of the Julius Wolff Institute won the ESB Clinical Biomechanics Award. The award consists of a certificate and 1000 Euros.
