Fixation Device for Unicondylar Prosthesis

原文（中国語）

A tibial component includes a baseplate component that has an articular side and a bone contact side opposite the articular side. A peg extends from the bone contact side such that an acute angle is formed between a longitudinal axis of the peg and the bone contact side of the baseplate component. The peg includes a distal tip, an anterior portion, and a posterior portion. The distal tip defines a first radius of curvature, the anterior portion has a spherical portion that defines a second radius of curvature and extends from the distal tip, and the posterior portion has a conical portion that defines a taper angle relative to a longitudinal axis of the peg and extends from the distal tip.
