Abstract: An expandable intervertebral cage includes vertically opposed superior and inferior plates and longitudinally opposed distal and proximal wedges disposed between the plates. The wedges define ramps that engage complimentary ramps of the superior and inferior plates to increase a vertical distance between the plates. An actuator is located between the plates, defines a central, longitudinal axis, and is coupled to the wedges such that, as the actuator rotates about the axis, at least one of the wedges moves longitudinally relative to the other, thereby increasing the vertical separation distance. At least one locking component is insertable within a receptacle at least partially defined by the proximal wedge and is configured to transition from an unlocked configuration, where the actuator is rotatable relative to the proximal wedge, to a locked configuration, where the actuator is rotationally affixed relative to the proximal wedge.

Abstract: Embodiments of the present invention include a convertible prosthesis that is capable of conversion from a humeral head replacement to a reverse reconstruction without any removal of parts integrated into the patient's bony anatomy (e.g. implant stems). A desired overall implant inclination angle may be achieved by matching various implant stems with various reverse inserts, thus permitting a resection surface to be matched with an implant stem selection while also permitting a desired overall implant inclination angle to be achieved through the selection of an appropriate insert.

Abstract: The invention relates to a medical device for treating hip joint osteoarthritis in a human patient by providing at least one artificial hip joint surface, the hip joint comprising a natural acetabulum, being a part of the pelvic bone, and a caput femur being a part of the femoral bone, and having a partly spherical form having a largest diameter, wherein said medical device comprises: a prosthetic part or a bone plug configured to be placed in a hole created in the pelvic bone. The invention is characterized in that said medical device further comprises a supporting member connected to said prosthetic part or bone plug. The supporting member is configured to be inserted into said hole from the abdominal side of the acetabulum, and be placed in contact with the bone surrounding the hole on the acetabulum side of the pelvic bone, for carrying load placed on caput femur from the weight of said human patient. Further, the prosthetic part or a bone plug has a diameter not exceeding the diameter of the natural acetabulum.

Abstract: A modular acetabular cup assembly includes an acetabular cup, and a liner seated in the cup. The cup includes an end face, an apex opposite the end face, and a central axis extending between the apex and a center point of the end face. The liner includes an articular surface having a center of rotation which defines a pivot point of the acetabular cup assembly. In certain embodiments, the pivot point is laterally offset from the center point such that the end face is located between the pivot point and the apex.

Abstract: An expandable intervertebral implant is provided for insertion into an intervertebral space defined by adjacent vertebrae. The expandable intervertebral implant includes a pair of outer sleeve portions and an inner core disposed between the outer sleeve portions. Movement of the inner core relative to the outer sleeve portions causes the outers sleeve portions to deflect away from each other, thereby engaging the expandable intervertebral implant with the vertebrae and adjusting the height of the intervertebral space.

Abstract: A medical device for implantation in a hip joint of a human patient, the natural hip joint having a ball shaped caput femur as the proximal part of the femoral bone with a convex hip joint surface towards the center of the hip joint and a bowl shaped acetabulum as part of the pelvic bone with a concave hip joint surface towards the center of the hip joint. The medical device comprising; an artificial caput femur, comprising a convex surface towards the center of the hip joint. The artificial convex caput femur is adapted to, when implanted: be fixated to the pelvic bone of the human patient, and be in movable connection with an artificial acetabulum surface fixated to the femoral bone of the patient, thereby forming a ball and socket joint. The medical device further comprises a fixation element comprising a fixation surface adapted to be in contact with the surface of the acetabulum and adapted to fixate the artificial convex caput femur to at least the acetabulum of the pelvic bone.
