Modified Lapidus arthrodesis is a versatile and powerful procedure for correcting the hallux valgus deformity typically associated with significant metatarsus primus varus or increased first ray mobility. Traditionally, patients have remained non-weightbearing until the arthrodesis has consolidated. More recently, numerous studies have evaluated the outcomes of early postoperative weightbearing using a variety of fixation constructs. The present retrospective cohort study evaluated 136 consecutive patients who had undergone modified Lapidus arthrodesis for hallux valgus deformity with conventional, crossed, solid core, screw fixation, were enrolled in an early weightbearing protocol, and were followed for 12 months. All the patients were partial weightbearing in a protective boot a mean of 12.2 (SD ± 4.36) days after surgery, with full weightbearing at 34.4 (SD ± 11.89) days. Union was achieved in 133 patients (97.8%). Of the 3 (2.2%) patients with nonunion, 2 (1.5%) remained asymptomatic. The mean time to radiographic union was 65 (SD ± 37.24) days. Significant improvement was seen in the first intermetatarsal angle and hallux abductus angle after surgery (p < .0001). Deformity correction was not compromised by early weightbearing and was well maintained over time. These results support early weightbearing with traditional crossed screw fixation for modified Lapidus arthrodesis with outcomes and complication rates comparable to those previously published.
