Paragraph Number

9

Implementations may include one or more of the following features. The arthroplasty implant system may include an arthroplasty implant that may include: an articular implant where the articular implant is embedded within a bone pocket of the distal articular surface when the tether couples the articular implant to the bone anchor such that bone pocket retains the articular implant in place during osseointegration of the articular implant to the metatarsal bone. The arthroplasty implant may include a spacer configured to maintain separation between the distal articular surface and an articular surface of an adjacent phalanx bone. The arthroplasty implant may include: a body having a joint-facing articular surface and a convex posterior surface configured to engage the distal articular surface by way of a bone pocket formed within the distal articular surface; an edge between the joint-facing articular surface and the convex posterior surface; and a connector configured to engage with the tether and secure the arthroplasty implant to the tether.
