• ABSTRACT
    • The evolution of Lapidus fixation has been strongly associated with the understanding of the anatomy and function of the first tarsometatarsal joint, the mechanism of hypermobility of the first tarsometatarsal joint, and cause of the hallux valgus deformity in 3 dimensions. Some methods, such as plantar plating, nitinol staples, and intramedullary fixation, have proven to be stronger biomechanically in cadaveric testing. Theoretically, stable fixation will reduce the rate of complications, in particular, that of nonunion and allow for early postoperative weight-bearing. Further clinical studies are needed to examine whether current biomechanical studies will translate to relevant clinical outcomes.
