New servo-hydraulic testing machine for Freiburg researchers

Key areas of research at the Orthopaedic and Trauma Surgery Clinic at the Medical Center, University of Freiburg, Germany, include clinical studies, biomechanics and basic research (cartilage tissue engineering). For several months now, researchers have been able to call on a Zwick servo-hydraulic testing machine for use in biomechanical projects.

The focus of the biomechanical research in the laboratory is on fundamental connections between bone quality, osteosynthesis and implant design Staff in the department staff attach great importance to the link with practical clinical aspects which determine the direction of the projects.

Previously only static tests were carried out for research purposes, for example on bone fixation materials. To enable the additional insights offered by fatigue tests to be channelled into research, a Zwick servo-hydraulic testing machine has recently been put into operation. The HC 10 Compact (Fmax 10 kN) is assigned to R&D and is used for in-vitro tests.

The results of dynamic fatigue tests on bone-implant constructs are correlated with modern imaging methods (amplifier screens, computed tomography). Direct connection of the testing machine to other dynamic measuring instruments (Zebris) enables additional analysis of the tests.

"Preliminary tests at Zwick's premises in Ulm, the intuitive software operation and the customer support all convinced us that the Zwick solution was the right choice," states Dr Lukas Konstantinidis of the Orthopaedic and Trauma Surgery Clinic.
