[Osteosynthesis of tibial valgus osteotomies by goniometric CH-N external fixator].
The authors present technique and results of a new external fixator, the < < goniometric > > external fixator CH-N for osteosynthesis of high tibial osteotomy for arthritic varus knee deformity on 86 kness (75 patients). ⋯ The principle of this special < < goniometri > > external fixator is based on the < < goniometric > > central joint in the frontal plane, this allows to guide the screws during osteotomy in the predesigned position and to control the correction during and after the procedure, in contrary to the others current system either internal or external. Any faulty correction can be modified. With its distal screwing axis, it allows axial dynamization. There are only some but not serious incoveniences due to the application of pins (temporary neuromuscular problems and pin-track infections.
