About Medichanical Engineering

Medichanical Engineering ApS (ME) was founded as a consequence of a new invention – X-pander – made by Poul Torben Nielsen (PTN); chief surgeon in orthopedics and responsible for hip and knee arthroplasties (implants) in Northern Jutland, Denmark. The idea for the invention emerged from existing challenges in the everyday work of PTN and other orthopedic surgeons, challenges regarding fixation of the pelvic component (the cup) of a hip implant.

For the early development of X-pander, PTN teamed up with engineers Eske W. Petersen (EWP) and Søren G. Buch (SGB) and together they developed the first prototypes of X-pander. By January 2011 the potential of the project was so obvious that the team could attract the interest of the Danish venture fund Seed Capital. ME was then founded by PTN, EWP and SGB. DTU Symbion INNOVATION and Seed Capital provided the resources needed to take X-pander through clinical trials, achieve proof of concept and onto the market.
