[The reorientational rearthrodesis of the upper ankle joint following failed arthrodesis].
There are three important principles for the correction of nonunion and/or malunion of the ankle joint: (1) reorientation back to anatomic shape and to the normal biomechanical axis of the ankle and foot; (2) respect for the biology of bone by resecting all sclerotic bone and/or transplantation of autogenous bone graft; and (3) achievement of optimal biomechanical stability by using the four-screw technique, a limited-contact dynamic-compression plate or a blade plate. CT scanning is the most reliable method for detecting nonunion of the ankle joint after arthrodesis. According to Saltzman, in order to understand the pathology of malunions and nonunions and to plan their correction, weight-bearing anteroposterior radiographs with a 20 degrees internal rotation of the feet, precise lateral views, and rear views of both sides are highly recommended.
