The goal of surgical treatment in femorotibial fractures is a perfect reduction of the bone fragments especially when articular surface is involved, the final step being realization of stable fixation. This enables less painful motion of the knee in the initial postoperative period, while stabilizing the fracture in the reduced position. Muscle forces acting on the bone fragments often determine their displacement. Traction alone can restore their normal position, but may result in an axial misalignment, instead of correcting it. The options available to stabilize these fractures have multiplied during the past few years, but the main problem remains the correct positioning of the bone fragments in the anatomical position, followed by the use of screws and implants to provide greater initial stability. Because of the large forces needed to reposition the bone fragments which are displaced into unexpected positions and because the fragments must be kept in the right position until the stabilisation is achieved, it is practically impossible for one orthopaedist to make the fracture reduction, usually two or three specialists being needed for the procedure completion. That's why the authors conceived a dedicated device.
