【 摘 要 】

Category:BunionIntroduction/Purpose:Fixation with relative stability has been shown to provide a rapid, more biological osseous incorporation than primary bone healing,1 theoretically supporting earlier weight bearing following osteotomy and or fusion. One such relative stability construct is 90-90 biplanar locked plating, which previously demonstrated superior biomechanical properties compared to a traditional Lapidus plate and interfragmentary-screw construct.2 Plantar, tension-side fixation is another approach for improved stability with Lapidus fusion, though the required plantar exposure has limited widespread adoption. Thus, a two-plate construct was designed to provide tension-side fixation and relative stability healing, while allowing application through a conventional incision. We tested the hypothesis that biplanar plating with tension-side fixation (low-profile straight dorsal plate and anatomic medial-plantar plate), would demonstrate improved mechanical stability versus the previously-tested...
