Arthrodesis of the hip with osteotomy and fixation with angled plate and transarticular screws. (Indications and limitations).

The writers describe their technique of arthrodesis with two transarticular screws and displacement osteotomy, fixed by means of Ruggieri & Salvagni's angled plate. This method is indicated in painful, rigid unilateral arthrosis of the hip in middle-aged subjects who are still active and working. The angled plate enables the diaphysis to be displaced medially, thus shifting the weight bearing axis; it also corrects any axial deviations of the femoral shaft and encourages rapid consolidation of the osteotomy and the arthrodesis.
