1. Of all the procedures for correction of drop-foot, the posterior arthrodesis gives the most durable results.
2. The operation of posterior arthrodesis is simple and not dangerous.
3. Good results are obtained with all procedures used for posterior arthrodesis.
4. The posterior "artrorise", according to Nové-Josserand, however, is, in my opinion, preferable to all the others, because it always assures a sufficient bone-blocking process.
