A reverse shoulder orthopaedic implant includes a glenosphere component having a lateral bearing surface configured to articulate with a humeral cup of a humeral prosthesis. A metaglene component includes a platform configured to receive glenosphere component.

An implantable medical device for implantation in a hip joint of a human patient is provided. The medical device comprises: at least one artificial hip joint surface adapted to replace at least the surface of at least one of the caput femur and acetabulum. At least one artificial hip joint surface comprises: a positioning hole with at least one opening in said at least one artificial hip joint surface. The hole is adapted to be placed and dimensioned such that the medical device is adapted to be fitted using a positioning shaft and at least partly surround the shaft, for positioning the at least one artificial hip joint surface in a desired position in the hip joint. The hole is adapted to be fitted using the positioning shaft, when the shaft is stabilized and placed in at least one of the femoral bone and the pelvic bone for positioning said medical device inside the hip joint.

A stand-alone expandable interbody spinal fusion device, including a superior component, an inferior component, an expansion mechanism operatively arranged to displace the superior component in a first direction relative to the inferior component about a first hinge, and a locking mechanism. The locking mechanism including a plate operatively arranged to pivot about a second hinge, the plate further including a first through-bore and a first plurality of teeth, a pawl operatively arranged to pivot about a third hinge, the pawl further including a second through-bore, and a post operatively arranged to pass through the second and third through-bores such that after the superior component is displaced in the first direction, the locking mechanism prevents displacement of the superior component in a second direction, opposite the first direction.

An expandable implant includes an upper main support of bone, a lower main support coupled to the upper main support, the lower main support comprising a first coupling feature and a second coupling feature being substantially parallel to the first coupling feature, and a control assembly configured to control relative movement between the upper main support and the lower main support, the control assembly including a first control member configured to engage the upper main support and the lower main support and interface with the first coupling feature a second control member configured to engage the upper main support and the lower main support and interface with the second coupling feature, and a control shaft configured to be received by the first control member and the second control member, wherein manipulation of the control shaft causes relative movement between the upper main support and the lower main support.

A system for performing interbody fusion surgery including an expandable intervertebral spacer and specialized instruments for choosing the correct size of implant, implanting the device within the intervertebral space, and for delivery of bone graft or bone substitute to the interior of the implant.

A prosthesis for primary artrodhesis can be used for artroplasty and a prosthesis for artroplasty comprises members for artrodhesis. The prosthesis (1b) for primary artrodhesis comprises a locking member (33b) with an attachment portion (16b) which is insertable into a hole (8b) in a first attachment member (4b) of the prosthesis for location of the locking member therein, and a lockable member (34b) integral with a second attachment member (5b) of the prosthesis. The lockable member (34b) is configured for adjustable setting thereof relative to the locking member (33b) and for fixation thereof, in set position, to the locking member. Alternatively, the lockable member comprises an attachment portion which is insertable into a hole in the second attachment member for location of the lockable member therein. At the prosthesis for artroplasty, the hole in the first screw-like attachment member is partly configured to define a press fit with an attachment pin of a socket member and partly threaded to permit, after removal of the socket member, during artrodhesis, securing by screwing in the hole of the locking member for cooperation with a lockable member which is configured for adjustable setting thereof relative to the locking member and for fixation thereof, in set position, to the locking member.

A device and methods for intervertebral spinal fusion of adjacent intervertebral bodies. An intervertebral spacer is positioned within a narrow disc space between adjacent intervertebral bodies of a patient. The spacer is arranged with upper and lower guides. The guides are adapted to simultaneously guide the deployment of upper and lower anchors of an anchoring device into their respective intervertebral bodies. The spacer is also adapted to lock the upper and lower anchors to the spacer in the deployed position.

A spinal implant for placement between first and second vertebrae includes a housing having first and second axial end surfaces and a bore extending along an axis through the housing and between the end surfaces. A first projection extends at least partially about the axis and including a channel. A lift is slidably received in the bore and includes threads along its length. A collar is threadably engaged with the lift and extends into the channel on the housing such that the projection prevents axial movement of the collar relative to the housing. Rotation of the collar about the axis causes the lift to move axially relative to the collar and the housing for adjusting the height of the implant.

A trial liner for fitting in a shell part of an orthopaedic joint prosthesis has a concave inner bearing surface for articulation with a head part, and an opposite outer surface. The liner has first and second portions which are separated by a slot extending between the inner and outer surfaces which has first and second ends. The slot divides the liner into first and second portions which are connected to one another by means of a first hinge at the first end of the slot and a second hinge at the second end of the slot. Each of the first and second portions has a locking feature in the form of a recess or protrusion which can engage a corresponding locking feature on the internal surface of a shell part to lock the liner into the shell part. The hinges allow the first portion of the liner to pivot relative to the second portion between first and second configurations, in which the distance between the first and second portions is less in the second configuration than in the first configuration.

A trial liner system for use in hip arthroplasty. The liner system includes a first trial liner having a generally convex outer surface and a generally concave inner surface, the generally concave inner surface having a first locking mechanism. The liner also includes a second trial liner having a generally convex outer surface and a generally concave inner surface The generally convex outer surface includes a second locking mechanism adapted to lock with the first locking mechanism of the first trial liner when the second trial liner is inserted into the first trial liner.
