When “Coxa Pedis” pronatory dysplasia is structured in a rigid flat valgus foot, correction imposes selective link removal and the most resistant hindrance springs from an abnormal lenght of talar bone, principal reason in producing and mantaining its infero-medial irreducible subluxation.
Whereas in talus-navicolar-calcaneal joint the chondral surfacing is healthy, in order to avoid uneconomic subtraction arthrodesis, a directional shortening technique able to mobilize and relocate talus in right glenoid center, is its neck resection – reorientation osteotomy. This way was firstly proposed by B. Regnault in terms of a linear and precise procedure, with quite simple surgical steps but however finalized to carefully respect the endostal hematic circle and to realize an absolutely valid compression synthesis; nevertheless elevated output, it remains poorly diffused and in appropriate indications it would be desirable more utilization.
