ANKLE ARTHRODESIS WITH INTRAMEDULLARY RETROGRADE NAIL FOR BONE TUMORS. PRELIMINARY RESULTS AND SURGICAL TECHNIQUE.

We strongly think, that although not necessary in relation to an oncology point of view, the possibility of secondary arthritic changes in adjacent foot joints that occur, with time, due to the loss of tibiotalar motion is quite significant, and more frequently found in the subtalar joints. 18 The sacrifice of the subtalar joints supressing the motion also in this joint, decreases significantly the pain and increases the mechanical support of the arthrodesis, contributing also for the short period that the distal calcaneotalofibular fusion demands to occur (4 to 6 months), and with the achievement of that distal fusion, allowing stability for a quicker proximal osteotomy fusion.
