Grice-Green's extra-articular subtalar arthrodesis. 1. Notes on the operative technique.

Although Grice's operation has been used all over the world, no systematic account of it has been found in the literature (including publications dealing with technique), which presents it in terms related to the basic "classical" principles on which the operation was conceived. The present description of the authors' special technique is presented with these basic principles in mind. If executed with precision, it appears to be reliable and to conform to these basic requirements. The various stages are illustrated and a typical case is shown which supports the validity of the concept.
