The fusion device for fusing a synovial joint of a human or animal patient, in particular a human facet joint, finger joint or toe joint, includes two pin-shaped anchorage portions and arranged therebetween a stabilization portion. The anchorage portions include a thermoplastic material which is liquefiable by mechanical vibration. The stabilization portion preferably has a surface which is equipped for enhancing osseointegration. The anchorage portions have a greater thickness and a greater depth than the stabilization portion. Then the fusion device is pushed between the articular surfaces and mechanical vibration, in particular ultrasonic vibration, is applied to the proximal face of the fusion device. Thereby the liquefiable material is liquefied where in contact with the bone tissue and penetrates into the bone tissue, where after re-solidification it constitutes a positive fit connection between the fusion device and the bone tissue.

Disclosed is a surgical targeting device for assisting placement of an elongated guidance member in a bone. The targeting device comprises a bottom portion having a dome-shaped convex outer surface and comprising a guidance through-hole extending along a guidance through-hole central axis for receiving the guidance member. A top portion of the targeting device is configured to be gripped by a tool. Further, a surgical system is disclosed which comprises the surgical targeting device.

A targeting guide includes a body defining a first guide hole sized and configured to receive a guide sleeve therethrough. The first guide hole extends through the body on a first axis. An alignment arm extends between a first end and a second end. The first end is coupled to the body. A tip extends from the second end of the alignment arm. A free end of the tip is aligned with the first axis of the first guide hole.

Various embodiments of devices, systems, and methods for surgical procedures, including spring-fit guides for improved guidance of surgical instruments, are disclosed.

A plating system includes a bone plate including an aperture. A locking member is receivable in the aperture to attach the bone plate to a joint. The plating system includes a guide including a body having a first end portion, a second end portion, an attachment portion attached to the bone plate, and a rotating portion including a sleeve to receive a drill or a guide wire. The first end portion of the body is rotationally connected to the attachment portion to pivot the body about a first axis to move the sleeve, and the rotating portion is rotationally connected to the second end portion of the body of the guide to pivot the rotating portion about a second axis to move the sleeve. The rotating portion translates along the second axis to move the sleeve, and the sleeve defines one of a plurality of trajectories.

This disclosure is directed to methods for reconstructing an unstable triangular fibrocartilage complex (TFCC). Exemplary methods include preparing, delivering, and fixating a graft within a distal radioulnar joint in a manner that restores the functionality to the TFCC, thereby improving the joint kinematics of the radioulnar joint.

A bone cut guide includes a first portion having a first cut slot and having an aperture for receiving a wire to connect the first portion to a first bone. A second portion has a second cut slot and a second aperture for receiving a second wire to connect the second portion to a second bone. The first portion and the second portion are movably connected to each other to allow the first bone and the second bone to move relative to each other.

A surgical drill alignment guide is disclosed that can provide an accurate trajectory for placement of a bone screw along a longitudinal axis of a bone.

A radiolucent, 3-D printed soft tissue retractor includes an elongate, curved support body having a long central axis that exceeds the length of a short, transverse axis. A bone engaging concavity is provided on a first side of the body. A concave soft tissue retracting surface is provided on a second side of the body. An inflection point is provided on the body in between the bone engaging concavity and the soft tissue retracting surface. The soft tissue retractor is configured to cooperate with a second soft tissue retractor and a backing plate to retract tissue and stabilize bones during a surgical distal radius fracture repair.

A tool for locating the insertion point of a radial component of a wrist prosthesis on a human distal radius bone, the guide comprising a handle; a guide face attached to the handle, the guide face being of a shape configured to engage an articular surface of the distal radius bone; the guide face comprising three visual cues respectively adapted to align with a palmar corner of a radio-ulnar joint located on the distal radius, a dorsal corner of a radio-ulnar joint located on the distal radius, and a tip of a radial styloid located on the distal radius; the guide face further comprising an opening designating the insertion point, the opening being at a designated location on the guide face relative to the visual cues; and the opening adapted to facilitate the marking of the insertion point on the articular surface of the distal radius bone.
