A medical device for implantation in a hip joint of a patient, the natural hip joint having a ball shaped caput femur integrated with a collum femur having a collum and caput center axis, extending longitudinal along the collum and caput femur, in the center thereof, as the proximal part of the femoral bone with a convex hip joint surface towards the centre of the hip joint and a bowl shaped acetabulum as part of the pelvic bone with a concave hip joint surface towards the centre of the hip joint, the medical device comprising; an artificial caput femur comprising a convex surface towards the centre of the hip joint, an elongated portion adapted to be connected to a prosthetic spherical portion of said artificial convex caput femur and fixated to the pelvic bone of the human patient,

The present invention disclosed a method of producing a three-dimensional porous tissue in-growth structure. The method includes the steps of depositing a first layer of metal powder and scanning the first layer of metal powder with a laser beam to form a portion of a plurality of predetermined unit cells. Depositing at least one additional layer of metal powder onto a previous layer and repeating the step of scanning a laser beam for at least one of the additional layers in order to continuing forming the predetermined unit cells. The method further includes continuing the depositing and scanning steps to form a medical implant.

Devices and methods for treating one or more damaged, diseased, or traumatized portions of the spine, including intervertebral discs, to reduce or eliminate associated back pain. In one or more embodiments, the present invention relates to an expandable interbody spacer. The expandable interbody spacer may comprise a first jointed arm comprising a plurality of links pivotally coupled end to end. The expandable interbody spacer further may comprise a second jointed arm comprising a plurality of links pivotally coupled end to end. The first jointed arm and the second jointed arm may be interconnected at a proximal end of the expandable interbody spacer. The first jointed arm and the second jointed arm may be interconnected at a distal end of the expandable interbody spacer.

A tibial implant may include a plurality of geometrically conformal implant subunits. The implant subunits may be configured for individual insertion within a wedge-shaped-void of the tibia. The implant subunits may further be configured for assembly in order to provide an implant substantially covering an exposed portion of cortical bone formed when performing a surgical osteotomy. In some embodiments, some or all of the plurality of subunits may be mechanically interlocked with each other. Methods and kits for insertion and assembly of implants are further described.

An implant includes a plate having a plurality of fastener holes, the plurality of fastener holes being configured to receive a plurality of fasteners, respectively; a spacer coupled to the plate and configured to be inserted into a treatment region; and a fastener lock movably coupled to the plate and configured to lock the plurality of fasteners.

A distractible intervertebral implant configured to be inserted in an insertion direction into an intervertebral space that is defined between a first vertebral body and a second vertebral body is disclosed. The implant may include a first body and a second body. The first body may define an outer surface that is configured to engage the first vertebral body, and an opposing inner surface that defines a rail. The second body may define an outer surface that is configured to engage the second vertebral body, and an inner surface that defines a recess configured to receive the rail of the first body. The second body moves in a vertical direction toward the second vertebral body as the second body is slid over the first body and the rail is received in the recess.

According to some embodiments, a method of inserting a lateral implant within an intervertebral space defined between an upper vertebral member and a lower vertebral member includes creating a lateral passage through a subject in order to provide minimally invasive access to the intervertebral space, at least partially clearing out native tissue of the subject within and/or near the intervertebral space, positioning a base plate within the intervertebral space, wherein the base plate comprise an upper base plate and a lower base plate and advancing an implant between the upper base plate and the lower base plate so that the implant is urged into the intervertebral space and the upper vertebral member is distracted relative to the lower vertebral member.

A spinal implant is provided including an upper surface, a lower surface, a front surface and a back surface, two side surfaces extending between the upper surface and the lower surface, the two side surfaces extending between the front surface and the back surface and an opening positioned closer to the back surface than the front surface. The opening is provided to contain graft material that spans between a cortical rim of the upper vertebral body and the cortical rim of the lower vertebral body. The method includes packing the opening with graft material, wherein the graft material spans between the decorticated cortical rim of the upper vertebral body and the decorticated cortical rim of the lower vertebral body.

The present disclosure provides a glenoid implant system for a reverse shoulder implant system that includes a glenoid implant having a center post, and also includes an angled baseplate comprising a bone facing surface to face an implant site prepared in a glenoid region of a patient, and an implant facing surface to face and engage the glenoid implant and receive the center post of the glenoid implant, wherein the implant facing surface being at an angle with respect to a centerline of the bone facing surface.

Shoulder arthroplasty systems and configurations for components thereof are described. For example, implant systems for a total should arthroplasty (TSA), hemi shoulder arthroplasty, and reverse should arthroplasty (RSA) are described. In addition, exemplary configurations for baseplates, glenoid components, glenosphere components, humeral components, humeral head components, humerosocket components, connectors, and adaptors, are described.
