[Progress in external fixation].

The monofixateur opens up avenues in external skeleton fixation. Proceeding from Lambotte's groundwork and from the given anatomical conditions and biomechanical requirements, a system has been developed that ensures maximum effectiveness with a minimum of mechanical means and operative procedure. Of particular importance is the dual-application feature of the monofixateur system: it is equally indicated for static as well as dynamic fixation, and is quickly and easily adapted from one function to the other at any time as called for by the treatment process. This system provides for dynamic function when applied without fixation clamping jaws on one of the major bone fragments. It allows for functional axial compression to be exerted through muscle contraction and pressure, while simultaneously excluding the possibility of bending and rotation, thus effectively promoting the healing process. The monofixateur is indicated for treatment of closed, open and infected fractures, pseudarthrosis, osteotomy adaption, arthrodesis and joint transfixations. In brief, the advantages of external fixation by the monofixateur may be summarized as follows: Simple mechanical design affording precise function. High stability with small number of fixation components. Unilateral assembly of device in position biomechanically favorable. Static or dynamic fixation. Little patient impairment.
