Abstract
An implant for insertion into a tarsal sinus includes a metal body having a plurality of threads disposed thereon. The body also includes a generally smooth, non-threaded portion that provides an articulating surface for the bones of the joint. The non-threaded portion tapers along a length, decreasing in size toward the tarsal sinus opening. This configuration mimics the shape of the tarsal canal when the foot is bearing weight, and therefore distributes the weight over a relatively large surface area.
Claims13
A subtalar implant for insertion into a tarsal sinus, the implant comprising:
- a threaded portion including at least one thread disposed on an external surface thereof for engaging tissue in the tarsal sinus;
- and
- a generally smooth, non-threaded portion having a proximal end configured to be disposed adjacent an opening of the tarsal sinus and defining a first dimension, and a distal end disposed adjacent the threaded portion and defining a second dimension larger than the first dimension.
A subtalar implant for insertion into a tarsal sinus, the implant comprising:
- a one-piece body having a proximal end configured to be disposed adjacent an opening of the tarsal sinus and a distal end configured to be disposed inside the tarsal sinus away from the opening, the body including:
- a threaded portion having at least one thread disposed thereon for engaging tissue in the tarsal sinus, and
- a generally smooth, non-threaded portion forming a taper along a predetermined length, the taper increasing in size along the length from the proximal end of the body toward the threaded portion.
