An orthopedic implant with an inferior portion having a tibia contact surface configured to extend over a tibia; a superior portion opposite to the inferior portion having a tendon contact surface configured to change a position of a patellar tendon by lifting or tilting the patellar tendon when the curved surface of the first portion is engaged with the tibia; a fixation mechanism adapted to attach the orthopedic implant to the tibia; and an adjustment mechanism adapted to change a distance between the tendon contact surface and the tibia contact surface. The invention also includes a method for repositioning a patellar tendon of a patient.

An implant (30) for a mammalian bone joint (3) for spacing a first bone (2) of the joint from a second bone (1) of the joint while allowing translational movement of the second bone in relation to the first bone is described. The implant comprises (a) a distal part (31) configured for intramedullary engagement with an end of the second bone, (b) a proximal part (34) having a platform (15) configured for non-engaging abutment of an end of the first bone and translational movement thereon, and (c) an articulating coupling (10, 16) provided between the distal and proximal ends allowing controlled articulation of the first and second bones. The bone-abutting platform is shaped to conform to and translate upon the end of the first bone. A kit for assembly to form the implant of the invention, and the use of the implant to treat osteoarthritis in a bone joint, are also described.

An artificial functional spinal unit including an expandable intervertebral implant that can be inserted via a posterior surgical approach and used with one or more facet replacement devices to provide an anatomically correct range of motion is described. Lordotic and non-lordotic expandable, articulating implants and cages are described, along with embodiments of facet replacement devices and instruments for insertion. Methods of insertion are also described.

A modular variable blade augment including an augment component and a blade component. The blade component includes a buttress portion and a neck portion, with the neck portion having a body segment and a face segment that is contoured for mating engagement with an outer surface of the acetabular shell. The augment component has a first opening sized and shaped to receive insertion of the body segment, and which is also sized to accommodate selective adjustment of linear and angular orientations of the blade component relative to the augment component when the body segment is positioned in the first opening. Additionally, the body segment has a length that is sized to facilitate direct contact of the face segment with the acetabular shell when the modular variable blade augment is in an assembled configuration. Further, cement can be injected into the internal cavity to unitize the connection between the acetabular shell and the blade component.

A multi-section expandable device includes an expansion module, a first push member and a second push member disposed at front and rear ends of the expansion module, and a bolt screwedly connected to the first and second push members. When the bolt is tightened, the first push member and the second push member are pushed to approach each other so as to push the expansion module to generate a first-stage expansion and a second-stage expansion. The first-stage expansion enables the expansion module to expand laterally so as to adjust its width. The second-stage expansion is performed after the expansion module is laterally expanded to have a maximum width, so that the expansion module is longitudinally expanded to adjust its height. The multi-section expandable device not only has better support effect, but also avoids the wear of the contact surfaces of the vertebrae.

Interbody spacers are expandable horizontally and vertically by an application of axial force, and lockable in an expanded configuration. The spacers include support members interconnected to end bodies by pivotable link members. The spacers are introduced between vertebral bodies in a compressed configuration and expanded to fill the intervertebral space and provide support and selective lordotic correction. Graft material may be introduced into the expanded spacer. Provisional and/or supplementary locking means to lock the spacers in the expanded configuration. Embodiments of the spacers include symmetrically and asymmetrically configured spacers. Methods of expansion include symmetric expansion or asymmetric expansion along each of two directions.

A humeral head implant system includes a head component including a first articulating surface, a second bottom surface extending from the first spherical articulating surface, a first cavity extending a first distance into the head component from the second bottom surface, and a second cavity extending into the head component along a cavity axis. The head component defines a head axis extending through a center of the first articulating surface parallel to the cavity axis. A base component defines a slot extending from a first width to a second width. An insert component includes an insert body, a first engagement feature, and a slot engagement feature. The first engagement feature is received in the second cavity along the cavity axis. The insert body has an insert thickness less than the first distance, and the slot engagement feature slides into the slot in a direction transverse to the cavity axis.

A pre-sutured allograft construct and method of manufacture for repairing, replacing, reconstructing, or augmenting a hip or shoulder labrum may include a folded tissue portion extending from a first end to a second end and forming top, middle, and bottom folds. A stitched pattern secures the folded tissue portion into a graft roll having an overall length extending from a first adjustable region, through a central region, and through a second adjustable region. A continuous series of whip stitches extends from the first adjustable region, through the central region, and through the second adjustable region. A series of triple circumferential stitches overlays the whip stitches in the first and the second adjustable regions, while a series of circumferential stitches alternates with the whip stitches in the central region. The construct is pre-manufactured as an allograft product, but is adjustable during the surgical procedure within the body. Other embodiments are also disclosed.

The present invention involves a system and methods for assembling and implanting a vertebral body implant. The vertebral body implant includes, but is not necessarily limited to, an expandable core body and endplates that can be attached at both ends. Endplates of various shapes, sizes and angles are attachable to the expandable core so that a suitable vertebral body implant can be implanted between vertebrae.

The present invention provides an expandable fusion device capable of being installed inside an intervertebral disc space to maintain normal disc spacing and restore spinal stability, thereby facilitating an intervertebral fusion. In one embodiment, the fusion device includes a body portion, a first endplate, and a second endplate, the first and second endplates capable of being moved in a direction away from the body portion into an expanded configuration or capable of being moved towards the body portion into an unexpanded configuration. The fusion device is capable of being deployed and installed in both configurations.
