    • Disclosed embodiments describe a volar plate generally for use treating distal volar fractures. The volar plate is designed in accordance with anatomical features and is generally Y-shaped, having a wider distal head portion that tapers to a narrower proximal body portion. A plurality of holes in the distal head of the volar plate allow for fixation means to fix the position of bone fragments with respect to the volar plate. The plurality of holes in the distal head basically form two substantially non-linear rows, with the distal row generally curving inward proximally and the proximal row generally curving outward distally such that the fixation means inserted through the holes generally converge. A central cavity may be located in the proximal body of the volar plate to promote bone growth, and mounting screws may border the central cavity on either side to provide secure support. Additionally, K-wire holes may be included which are visually linked to corresponding holes in the distal head.
    • 公开的实施例描述了通常用于治疗远端桡骨骨折的手掌板。 根据解剖学特征设计瓣板,并且通常为Y形,具有朝较窄的近端主体部分逐渐变细的远端头部。 在瓣板的远侧头部中的多个孔允许固定装置固定骨片相对于手板的位置。 远侧头部中的多个孔基本上形成两个基本上非直线的行,其中远端行通常在近侧向内弯曲,并且近端排通常向外向外弯曲,使得插入穿过孔的固定装置通常会聚。 中心腔可以位于瓣板的近侧主体中以促进骨骼生长,并且安装螺钉可以与两侧的中心腔体相接触以提供安全的支撑。 此外,可以包括K线孔,其可视地连接到远侧头部中的相应孔。
