Artificial meniscal scaffolds characterized by a composite of circumferential polymer fiber network and orthogonal polymer fiber network embedded in an arcuate bioresorbable matrix comprised of collagen and hyaluronic acid. The orthogonal polymer fiber network prevents separation of the circumferential polymer fiber networks. The polymer fiber networks convert axial compressive forces on the scaffolds to tensile loads on the circumferential polymer fibers. The composite scaffold can be anchored to bone by novel anchoring components that protect the polymer fibers and ensure immediate securement of the artificial meniscal scaffold to bone.

The present technology provides patient-specific implants. The implants can include a plate having a geometry contoured to mate with an identified anatomical structure at a target position. The plate can include a first projection having a first contact surface with a first topography designed to mate with a corresponding first surface of a first vertebral body, and a second projection having a second contact surface with second topography designed to mate with a corresponding second surface of a second vertebral body. The first topography can be different than the second topography. In some embodiments, the first and/or second projection can be configured to contact, and have topographies designed to mate, with a plurality of surfaces, such as two adjacent surfaces, of the respective first and second vertebral bodies.

A system includes a first implant component and a second implant component. The first implant component is configured to be secured to a bone and includes a plate and a coupler extending upward from the plate and defining a coupler axis. The second implant component is configured to be coupled to the first implant component. The second implant component includes an articulation surface and defines a cavity configured to receive the coupler of the first implant component. The second implant component is couplable to the first implant component at a plurality of rotational orientations about the coupler axis.

Object: Provided is a dysphonia treatment tool in which a front surface piece is bent. Resolution means: A dysphonia treatment tool includes a plurality of clamping sections (1, 1) each including a front surface piece (1a) disposed from a cut end surface of thyroid cartilage incised to a front surface, and a rear surface piece (1b) disposed on a rear surface of the thyroid cartilage, and being fitted respectively to cut ends of the thyroid cartilage that are opposite each other, and a bridging section (2) linking the plurality of clamping sections (1, 1) to each other. The front surface piece (1a) is bent in an intermediation section between a base end and a distal end of the front surface piece (1a).

An apparatus includes a body extending from a first end to a second end. The first end is a leading end, and the second end includes a first coupling element configured to couple the body to a first other component. The body includes an external fixation element extending along a length of the first component. The external fixation element is configured to engage bone. Systems and methods are also disclosed.

The present disclosure provides for spinal implants configured for lateral insertion techniques deployable between a contracted position and an expanded position. The spinal implant may include a first endplate and a second endplate, each having a plurality of guide walls and inclined ramps. The spinal implant may further include a moving mechanism having first and second trolleys configured to act against the first and second plurality of ramps. The moving mechanism may further include a first set screw and a second set screw opposite the first set screw. The moving mechanism may be configured to operably adjust a spacing between the first and second endplates upon simultaneous rotation of the first and second set screws along a rotation axis, and may also operably adjust an angle of inclination between the first and second endplates upon rotating the first set screw or second set screw along the rotation axis.

An expandable interbody spacer that is delivered in the anterior approach with adjustable height and end plate angulation (lordosis). The expandable interbody spacer is configured to have an initial collapsed state having a first height suitable for being inserted into an intervertebral space defined by a pair of adjacent vertebrae, and an expanded state having a second height that is greater than the first height. The expandable interbody spacer may be expanded from the initial collapsed state to the expanded state in-situ. The expanded state increases the distance between the adjacent vertebrae and provides support to the adjacent vertebrae while bone fusion occurs and also provides rigid support between the adjacent vertebrae that withstands compressive forces. By inserting the expandable interbody spacer into the intervertebral space in the initial collapsed state, it is possible to perform the surgery percutaneously with minimal disruption to tissues surrounding the surgical site and intervening soft tissue structures.

Prostheses, acetabular apparatuses, and methods of use are disclosed. In some embodiments, an acetabular apparatus includes an acetabular cup, a pre-assembled liner and flange construct, and a dual mobility bearing (e.g., a dual articulating femoral head component and insert). In one embodiment, the pre-assembled liner and flange construct may be coupled together by a band coupled to the flanges, the band being arranged and configured to be pressed onto an outer surface of a liner. The pre-assembled liner and flange construct being arranged and configured to accept the dual mobility bearing so that it is freely rotatable relative thereto during use.

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.

The augments, systems and methods for supporting acetabular implants described herein can include an augment (100) for supporting an acetabular shell (90) having a first portion (136) of a locking mechanism. The system can also include a shell having a second portion of a locking mechanism (96). The first portion of the locking mechanism and the second portion of the locking mechanism can be adapted to move relative to one another from an unlocked state to a locked state to fixedly couple the augment to the shell. In some examples, the augment can be contourable to match the shape of a bone.
