Modifications of the Regnauld osteochondral autogenous graft for correction of hallux limitus/valgus: a 2-year review.

This study compares modifications of Regnauld's enclavement procedure, the in situ "hat-shaped" and in situ "inverted" osteochondral graft. A 2-year retrospective analysis consisted of patients' satisfaction, activity level, first metatarsophalangeal joint range of motion, and radiographic evaluations. The result of this study demonstrates that both the "hat" and "inverted" type grafts are highly successful and satisfactory procedures. However, the "inverted" technique is found to provide faster healing rates and a broader range of motion of the first metatarsophalangeal joint; it is more stable and technically easier to perform. Therefore, the "inverted" graft provides more consistent and predictable results for the treatment of hallux rigidus and hallux valgus.
