A soft anchor surgical fixation device includes two soft anchoring implants. The implants have a first elongate state where the implants may slide easily through a bone hole or tunnel, and a second axially compressed state where the implants are prevented from sliding through the bone hole or tunnel. The device also includes a suture pathway extending at least partially along and through the sidewalls of the implants. Tension on the suture transitions the implants from the first elongate state to the second compressed state.

Inflatable orthopedic implants and related methods are disclosed herein, e.g., for deploying such implants within an intervertebral space for use in spinal fusion surgery, other intervertebral surgical procedures, or other surgical procedures. The inflatable intervertebral implant can include a hollow inflatable body that can be configured in a compact state for insertion into a target intervertebral space between a pair of adjacent vertebral bodies. Once the vertebral bodies are separated or distracted, e.g., using one or more inflatable distractors, the hollow body of the inflatable implant can be inflated with bone cement or other curable material. When the curable material hardens, the inflated implant can form a rigid intervertebral support structure (e.g., a fusion cage) capable of maintaining the vertebral distraction and thereby enabling removal of the distractors.

An improved modular rotational device includes a first and second threaded coupler for affixation along the stem of an endoprosthetic device, for example, a humeral prosthesis or a femoral prosthesis. The rotational device axis of rotation is coaxial with the stem, and its axis of rotation is located in close proximity to the intramedullary stem of the prosthesis or in close proximity to the distal articulation of the prosthesis. A housing has a proximal and distal end with an axial bore therethrough for receiving an elongated stem of the device. A lobe ring may be utilized to limit the axis of rotation of the device. Additional endoprosthetic devices may be attached to male or female threaded couplers, or to Morse tapers. A plurality of suture attachments facilitates attachment of soft tissue thereto.

A tendon anchoring assembly that includes an anchor and a washer. The anchor includes an elongated body and a substantially circular head and the washer includes an inferior face having gripping protrusions, and a through hole sized to receive a portion of the substantially circular head. A shoulder implant assembly that can be used in conjunction with the tendon anchoring assembly is also disclosed.

An orthopedic medical device assembly that includes a first bearing for attachment to an implant and a second bearing for attachment to an implant, such as a glenosphere.

An osteotome having a shaft assembly that includes a guide extending in a longitudinal direction of the shaft assembly, and a blade adjacent the guide and extending in the longitudinal direction of the shaft assembly.

Methods of inserting and retaining interbody fusion material are disclosed. In some embodiments, the methods include inserting an anchored implant comprising a bone anchoring portion and an engagement portion. A method may also include inserting at least one bone fusion material within a disc space between two adjacent vertebral bodies. In some embodiments, a method includes driving the bone anchoring portion into an outer surface of at least one of the adjacent vertebral bodies and recessing the bone anchoring portion within the outer surface of the at least one adjacent vertebral body.

A prosthetic implant replaces hyaline cartilage in a synovial joint with a flexible polymer sliding surface, preferably of hydrogel, on a segmented support with an array of adjacent segments to which the hydrogel is molded. Adjacent segments are laterally and angularly displaceable permitting the implant to conform to rounded or irregular surfaces or to be rolled or folded for arthroscopic placement. Tension cables threaded through segments along a circuit can cinch segments together for stiffening the supporting layer and/or the cable can pull the implant against a bone surface. Adjacent segments can have inter-engaged structures. In some embodiments the segments are carried on a flexible foil or fibrous sheet.

An implantable tissue repair device containing a body having a biocompatible hydrogel and a plurality of tissue anchoring elements projecting from the body, where the anchoring elements are integrally formed with the body and have the same biocompatible hydrogel as the body, and the anchoring elements, in use, are arranged to enter apertures in a tissue and anchor the device to the tissue.

The invention provides a reticular fixation system and method for an articular cartilage. The system comprises an articular cartilage repair surface locator, a temporary fixation kirschner wire, a depth-control guide wire, a percussion device and a cartilage fixing piece. The method comprises: repositing an injured articular cartilage; placing a locator on a surface of the injured articular cartilage; fixing the locator to the articular cartilage and the bone temporarily; punching the fixing piece wire tunnels on the articular cartilage and the bone in a fixing piece guide channel of the locator; placing the fixing piece into a fixing piece wire guide channel; percussing a fixing piece nail into the tunnels of the articular cartilage and the bone; removing the temporary fixation kirschner wire; implanting a second fixing piece nail, and completing the articular cartilage repair. The invention can improve convenience and reliability of fixation of the injured cartilage.
