Fields of basic and clinical research
Software development:
CT/MR – Method of catching data of surfaces e.g. subchondral bone for pre-operative simulation of correcting osteotomies.
Program “Reoplan” da Algo4u (Thelen/Krause/Klaue):
Development of a Universal Internal Fixation Plate:
development of Osteosynthetic Fixation Plates and Screws:
Bone formation and regeneration:
Development of improved in Foot and Ankle Reconstruction techniques.
Development of specific implants and instruments to be used in Foot and Ankle surgery:
Nail for internal fixation of the hindfoot (tibio-calcaneal arthrodesis). It is essential to fix the hindfoot in anatomical alignment and under stable conditions to achieve secure bone healing. The bones of the hindfoot are aligned on a circular arc.
