Fields of basic and clinical research

–  Development of a computerized 3-D imaging system using personal computers to be used for diagnostic purposes in Orthopaedics and pre-operative simulation of corrective means.

–  Development of a Universal Internal Fixation Plate

–  Bone formation and regeneration

–  Development of prosthetic fixation with remodeling interface

–  Development of improved in Foot and Ankle Reconstruction techniques

–  Development of Osteosynthetic Fixation Plates and Screws

–  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.
