Preliminary report: modifications of the Regnauld osteochondral autogenous graft.

The enclavement procedure was originally described by Bernard Regnauld in 1968. The basal portion of the proximal phalanx of the hallux is used as an osteochondral autogenous graft in the treatment of hallux limitus, hallux rigidus, and hallux valgus. This paper presents a review of Regnauld's techniques, emphasizing an in situ modification of the inverted graft that allows for greater technical ease, increased stability, and improved graft viability, with more rapid incorporation.
