Tendon and Bone Regeneration

We are an interdisciplinary research group working tightly together with the clinical colleagues. This cooperation gives us the possibility to identify the problems in orthopedic and trauma surgery and to work on new strategies to solve them.

Local application

Healing processes can be promoted by the application of active substances. A major field of research in orthopedics is the application of growth factors for healing stimulation and antibiotics for the prevention and treatment of infections.

Mixing device for bone graft and drug
Experimental set-up for the in vitro investigation of the release kinetics of drugs from bone grafting material

Bone healing disorders and implant-associated infections are still a challenge in trauma and orthopedic surgery. Local application of active substances can promote endogenous healing processes, but also prevent or treat infections. At the same time, the necessary dosage and the systemic load is reduced, but also the availability on site is improved. Our group focuses on various possibilities of local application in various indications.

The developed biodegradable coating –based on the polymer poly(D,L-lactide)- for surgical material such as implants was extensively tested in vitro and in vivo for the application of antibiotics and bone healing stimulating factors. In addition to the optimization of the coating and the release kinetics, the effectiveness and biocompatibility was investigated.

Numerous bone substitutes are available for the treatment of bony defects. Ideally, the surgeon can enrich the appropriate material with an active substance to promote healing or fight bacteria. For this purpose, we have developed a perioperative approach which allows a fast and homogeneous mixture of substitute material with active substances and intensively analyzes the release kinetics of various antibiotics in vitro. Using a bone defect model we evaluated the effectivity of a bone graft (demineralized bone matrix, DBM) enriched with the osteoinductive factor BMP-2 by µCT and histology. We investigate the efficacy and cytotoxicity of newly discovered or modified antimicrobial substances in different in vitro approaches.
