Abstract: The implant (20) is shaped to generally mimic the form of the trapezium (12), or portions thereof. For example, the implant optionally defines a first metacarpal projection (32) and a second metacarpal projection (34) spaced from the first metacarpal projection to form a C-type, or cuff-type receptacle (36) for receiving the first metacarpal (15) such as the first and second metacarpal projections extend along either side of the first metacarpal. The receptacle optionally acts as a support surface (36A) for the first metacarpal during articulation thereof. In some embodiments, the first metacarpal projection is configured to extend adjacent the end portion of the first metacarpal that is adjacent the CMC joint (10) and the second metacarpal projection is configured to extend into the space (19) between the end portions of the first and second metacarpals (15, 18), thereby helping maintain the intermetacarpal spacing between the first and second metacarpals. The implant may comprise an inflatable cover for minimally invasive implantation.

Abstract translation: 植入物（20）的形状通常模拟梯形（12）或其部分的形式。 例如，植入物任选地限定与第一掌骨突起间隔开的第一掌骨突起（32）和第二掌骨突起（34），以形成C型或袖带型容器（36），用于接收第一掌骨（15） ），例如第一和第二掌骨突起沿着第一掌骨的任一侧延伸。 该插座任选地用作第一掌骨在其铰接期间的支撑表面（36A）。 在一些实施例中，第一掌骨突起构造成邻近第一掌骨的靠近CMC关节（10）的端部延伸，并且第二掌骨突出部被构造成延伸到第二掌骨端部的端部之间的空间（19） 第一和第二掌骨（15,18），从而有助于保持第一和第二掌骨之间的间距。 植入物可以包括用于微创植入的可充气盖。
