[The role of osteotomy in the treatment of pseudoarthroses.]

Osteotomies in the area of pseudoarthroses ensue from the necessity to correct biomechanical conditions at these sites. Depending on the site of osteotomy, we speak of intrafocal osteotomies, i. e. wedge-shaped resection (total or partial) of the pseudoarthrosis. The second type of osteotomy is transfocal osteotomy which is normal to the longitudinal axis of each fragment. The third type is parafocal osteotomy which is several centimeters from the pseudoarthrosis and the correction of biomechanical conditions is implemented in this osteotomy. The implementation of osteotomy markedly facilitates the procedure and shortens the time of operation. Healing of the pseudoarthrosis after osteotomy takes on average 5 months, of the osteotomy 7 months. The authors evaluate a group of 27 patients operated in 1982-1995. In all patients the pseudoarthrosis was cured. Key words: osteotomy, treatment of pseudoarthroses.
