Modified lapidus arthrodesis: rate of nonunion in 227 cases.
Several studies of Lapidus arthrodesis have commented on the rate of nonunion (ranging from 3.3% to 12.0%), although these figures are based on relatively small patient populations. This study retrospectively reviewed the medical records and radiographs of 211 consecutive patients (32 men, 179 women; mean age, 46.9 years) who received modified Lapidus arthrodesis for forefoot pathology in 227 feet. In all cases, the procedure was performed using joint curettage with subchondral plate preservation and screw fixation. Patients remained nonweightbearing for 6 to 8 weeks and were monitored for a minimum of 6 months postoperatively. Nonunion was seen in 12 (5.3%) of the 227 feet that underwent modified Lapidus arthrodesis.
