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.

An implant for repairing an articular cartilage defect site including an implant fixation portion with an upper segment and at least one bone interfacing segment and a top articulating portion with an articulating surface and an engagement surface. The upper segment includes a supporting plate with a first locking mechanism segment. The engagement surface includes a second locking mechanism segment. The first locking mechanism segment with at least two channels is structured to couple to the second locking mechanism segment with at least two protrusions. The at least one bone interfacing segment structured for insertion into the articular cartilage defect site. An implant including an implant fixation portion, a top articulating portion, and a locking mechanism with a first locking segment coupled to the upper segment and a second locking segment coupled to the at least one engagement surface and structured to couple to the first locking segment.

A method for pre-operative orthopedic planning includes obtaining only a high-resolution knee-joint scan of a patient, determining hip rotation center and ankle rotation center from anthropometric data based on personal data of the patient, and determining a mechanical axis of the knee joint based on the anthropometric data. The method also includes preparing at least a two-dimensional image model of the knee joint using the knee-joint scan and the determined mechanical axis, and preparing a pre-operative surgical plan based on the image of the knee joint.

A system for harvesting bone material from a bone may include a rotary cutter defining a rotary cutter longitudinal axis extending between a rotary cutter proximal end and a rotary cutter distal end. The rotary cutter may have a drive shaft configured to receive input torque, and an osteochondral cutter configured to cut the tissue and receive the tissue material in response to rotation of the osteochondral cutter under pressure against the tissue. The system may further include a bone port defining a bone port longitudinal axis extending between a bone port proximal end and a bone port distal end. The bone port may have a bone port cannulation sized to closely fit over the osteochondral cutter. At least one of the bone port proximal end and the bone port distal end may be securable to the tissue. A stratiform tissue graft may be delivered through the bone port.

A cement restrictor inserter instrument (130) comprises an inserter (131) having a handle (132) at a proximal end, a cement restrictor attachment formation (137) at a distal end for releasably attaching a cement restrictor (150), a shaft (136) extending from the proximal end to the distal end and a stop (138) on the shaft and between the proximal end and the distal end; and a body (140) having a shape corresponding to the shape of an orthopaedic prosthetic implant, a spacer (142), a visible depth guide feature (190) and a releasable attachment mechanism by which the body is releasably attachable to the shaft, and wherein the spacer is configured to position the visible depth guide feature at a fixed position relative to the inserter when the spacer abuts the stop corresponding to a target cement restrictor position when the visible depth guide feature is aligned with a feature of a bone of a patient in which the cement restrictor is to be inserted.

An orthopaedic joint replacement system is shown and described. The system includes a number of prosthetic components configured to be implanted into a patient's knee. The system also includes a number of surgical instruments configured for use in preparing the bones of the patient's knee to receive the implants. A method or technique for using the surgical instruments to prepare the bones is also disclosed.

A sacroiliac joint screw has a screw body having a head and a treaded shank with a self-drilling cutting tip. The screw body is cannulated and configured to receive a Steinmann pin for the purpose of a minimally invasive approach (MIS) for delivery to the sacroiliac joint (SI) while minimizing soft tissue damage. The self-drilling cutting tip creates a pilot hole. The threaded shank has a plurality of spiral cutting flutes, the spiral cutting flutes extend along a length of the threaded shank and are configured to provide a constant self-tapping feature. A plurality of bone harvesting windows are positioned in the spiral cutting flutes and are configured to pull in bone as the screw is advanced into the joint.

A reverse shoulder system can include, for example, a glenoid baseplate comprising a longitudinal axis, the glenoid baseplate further including a stem and a central channel within a sidewall of the stem. The stem can include a longitudinal axis. The longitudinal axis of the glenoid baseplate can be angled with respect to the longitudinal axis of the stem, wherein the longitudinal axis of the glenoid baseplate is not perpendicular with respect to the longitudinal axis of the stem. Other components including a glenosphere, tools, and methods of use are also disclosed.

Disclosed herein is a toe implant for replacing a portion of a human toe joint, as well as a related kit, surgical method, and method of manufacturing. Specifically, the toe implant may include a bearing member having a curved interface surface and a fixation member coupled to the bearing member. The fixation member may include a first portion having a non-porous barrier, and a tapered second portion.

Embodiments of devices, apparatuses, kits, and methods for repairing a human joint by suturing biological tissue to the articular surface of a bone at the joint (e.g., repairing defects in the humerus at the glenoid joint after an anterior shoulder dislocation) are described herein. Biological tissue may include hard tissue such as bone or a joint socket or soft tissue such as cartilage, ligaments, tendons, or muscle tissue.
