An Achilles tendon repair device comprises a handle for physician gripping and base having a first set of tendon rods disposed in an arcuate or U-shaped pattern about the base to engage the posterior surface of the tendon and impart a contour, or drape, the tendon in the posterior-anterior plane to increase the surface area for suturing. A second set of suture guide rods extend from the sides of the base and are spaced apart to allow insertion of suture needles along the entire length of the suture guide rods, and at any angle. A suture needle housing guide can be slidingly attached to the suture guide rods and includes sidewalls with predefined suture holes/angles. An adjustable clamping arm can engage the tendon's posterior surface such that the device grasps the tendon on both the anterior and posterior tendon surfaces simultaneously, while increasing posterior-anterior plane surface area to facilitate suturing.

Achilles tendon repair device

A method for surgical repair of an Achilles tendon may include positioning an instrument proximate the Achilles tendon. The instrument may include a handle and a plurality of tendon guides. The method may also include maneuvering the instrument such that the plurality of tendon guides is positioned anteriorly, posteriorly, laterally, and medially of the Achilles tendon, actuating the plurality of tendon guides to retain the Achilles tendon between the plurality of tendon guides, and using the instrument to insert a suture through the Achilles tendon along one or more trajectories, each of which is offset at least 10° from a coronal plane.

Achilles tendon repair systems and methods

An ankle arthroplasty system may have a talar prosthesis and a tibial prosthesis, each of which has an articular surface and a bone engagement surface. Each bone engagement surface may have an anterior-posterior curvature and a medial-lateral curvature with a convex shape. A burr with a rotatable cutting element may be used to form a prepared surface on the talus or the tibia to receive the corresponding prosthesis. A cutting guide may be used to guide motion of the burr; the cutting guide may include a base and an arm movably coupled to the base. One of the base and the arm may have a guide surface, and the other may have a follower that slides along the guide surface to constrain motion of the burr such that the prepared surface has at least one concave curvature and one convex curvature.

Joint replacement spacers

Ankle arthroplasty systems and methods

A suture guide may include a base, a tissue guard extending from the base, and two flanking posts affixed to the base on opposite sides of the tissue guard. The posts may extend from the base in parallel planes, and each of the posts may define a plurality of channels passing through its width. The channels may be so oriented that, for each post (a) the channels define suture needle guide paths in one or more planes, and (b) at least one channel is not perpendicular to a long axis of the first flanking post, so that it defines an oblique suture needle guide path. The tissue guard may be connected to the base by a connector so adjustable as to control spacing between the posts and the tissue guard.

Suture guide and ruptured tissue repair

A suture guide may include a base, a first tissue guard extending from the base, and two flanking posts affixed to the base on opposite sides of the tissue guard. The posts may extend from the base, and each of the posts may define a plurality of channels passing through its width. The channels may be so oriented that, for each post (a) the channels define suture needle guide paths in one or more planes, and (b) at least one channel passes through the first flanking post in a direction that is not parallel to a width axis W passing through the width of the first flanking post, so that it defines an oblique suture needle guide path. The first tissue guard may be connected to the base by a connector so adjustable as to control spacing between the posts and the first tissue guard.

Joint replacement spacers that fully seat against the cut surface of a bone while remaining free to move on the cut surface within prescribed limits; methods of joint replacement using such spacers.
