The invention relates to a glenoid (shoulder socket) implant prosthesis, a humeral implant prosthesis, devices for implanting glenoid and humeral implant prostheses, and less invasive methods of their use for the treatment of an injured or damaged shoulder.

An orthopaedic prosthesis is disclosed. The orthopaedic prosthesis includes a frame including a plurality of beams defining an open-cell structure and a shell applied to the frame. The frame includes a proximal arm, a distal arm, and a central body connecting the proximal arm to the distal arm. The shell extends over the proximal arm, the distal arm, and the central body of the frame. A method of implanting an orthopaedic prosthesis is also disclosed.

Spinal interbody cages are provided that include a bulk interbody cage, a top face, a bottom face, a top mesh structure, a bottom mesh structure, pillars, and slots. The top and bottom faces are exterior surfaces of the bulk interbody cage having a top central opening and a bottom central opening, respectively. The top and bottom mesh structures extend from the bulk interbody cage across the top central opening and the bottom central opening, respectively. The pillars are for contacting vertebral bodies. The slots are to be occupied by bone of the vertebral bodies and/or by bone of a bone graft. The spinal interbody cage has a Young's modulus of elasticity of at least 3 GPa, and has a ratio of the sum of (i) the volumes of the slots to (ii) the sum of the volumes of the pillars and the volumes of the slots of 0.40:1 to 0.90:1.

The present disclosure provides systems and methods for repairing a defect on a portion of an articular surface of a human body, particularly of the glenoid. More particularly, the present disclosure provides systems and methods for repairing both a glenoid cavity and a glenoid rim of the glenoid using a single implant.

An implant assembly including an expandable vertebral body replacement implant. Two outer cores disposed on opposing ends of an inner are configured to move away from each other when the inner core is actuated. The implant assembly may include removable endplate configured to engage vertebral bodies as interbody spacer or through a corpectomy. The implant may include a locking mechanism to prevent collapse or movement the implant assembly after implantation. The locking mechanism may be automatically engage after removal of an inserter instrument from the implant assembly.

A knee arthroplasty system may have a femoral joint prosthesis with a femoral bone engagement surface with an anterior portion, a posterior portion, and a distal portion that connects the anterior portion to the posterior portion. A first femoral anchoring member may protrude from the distal portion, and may be connected to the anterior portion with a primary femoral web. A tibial resection guide may have a base member and a guide member with a slot that guides a cutting blade to resect the tibial plateau. The guide member may slide along an arcuate path relative to the base member.

A locking member for implantation in a hip joint of a patient is disclosed. The locking member is adapted to assist in the fixation of a medical device, having an artificial hollow caput femur surface, to the collum and/or caput femur, wherein the artificial caput femur surface comprises at least one extending portion adapted to clasp a portion of the caput and/or collum femur. The locking member comprises an element adapted to lock the artificial caput femur surface such that the caput femur remains clasped and restrained in the artificial caput femur surface.

A vertebral body replacement device includes a first member and a first footplate detachably connectable to the first member, a second member and a second footplate detachably connectable to the second member, and a central member detachably connectable to the first member. The first member is displaceable relative to the second member in response to rotation of the central member relative to the first member to adjust the length of the vertebral body replacement device. The first footplate includes a first surface oriented toward the first member, a second surface oriented away from the first member, and a sidewall extending between the first surface and the second surface. The first surface includes an alignment slot facing the first member. The alignment slot is open through the sidewall of the first footplate and configured to slidingly engage the first member to orient the first footplate relative to the first member.

A vertebral body replacement device includes a first member and a first footplate detachably connectable to the first member, a second member and a second footplate detachably connectable to the second member, and a central member detachably connectable to the first member. The first member is axially displaceable relative to the second member in response to rotation of the central member relative to the first member to adjust the length of the vertebral body replacement device. The first member includes a pair of first fastener holes and a pair of second fastener holes angularly offset from the first fastener holes. The first footplate includes an aperture configured to align with one of the first fastener holes to orient the footplate in a first position or one of the second fastener holes to orient the footplate in a second position.

The present disclosure relates to a system and method for repairing an articular surface. A guide pin may be secured to an articular surface of a glenoid, wherein the guide pin defines a working axis and the working axis is positioned at an angle relative to the articular surface, wherein angle is less than or equal to 90 degrees. An excision device may be advanced over the guide pin, wherein the excision device includes a cannulated shaft and at least one cutter, wherein the at least one cutter is generally aligned in a single plane. A generally hemi-spherical excision site may be formed with the excision device within the articular surface of the glenoid.
