A blade plate for high tibial osteotomies
Jackson reported in 1961 on a large series of successful osteotomies of the upper tibia. Since that time the high tibial osteotomy has become an established procedure for the treatment of idiopathic and post-traumatic valgus and varus deformities of the lower extremity. Boitzy, Coventry, Engelhardt, Haas, Insall, and Rutt state that the wedge-resection osteotomy should not be carried completely through the opposite cortex so that the cortex-periosteal envelope will be preserved on one side as a stabilizing structure. In that way it can act as a hinge for closing the osteotomy. The associated tensionband effect provides additional stability.
