Today's foot and ankle surgeon has multiple options when choosing a fixation device for Lapidus arthrodesis, many of which have well-documented nonunion rates. The present study aimed to fill a void in the current foot and ankle literature by establishing a nonunion rate for staple fixation for the Lapidus procedure. The present retrospective analysis of the medical record focused on nickel-titanium staples that were inserted in a delta configuration to yield a stable construct for first metatarsal-cuneiform fusion. The patients were kept strictly non-weightbearing for the first 6聽weeks postoperatively. Weightbearing progressed at that point according to聽the radiographic findings of each case. The data from 35 consecutive patients were analyzed (25 females, 10聽males; mean age 43.1聽[range 15 to 72] years in whom a Lapidus arthrodesis was performed using staple fixation in 36 feet. The patients were followed until fusion was noted and pain had resolved. Pain resolution occurred at 6聽weeks in the earliest cases and several years in others. The incidence of nonunion was 3 (8.3%) of 36 when staple fixation was used for first metatarsal-medial cuneiform arthrodesis.
