Abstract:
Disclosed herein are components of a reverse shoulder prosthesis. In an embodiment, a reverse shoulder prosthesis includes a humeral adapter tray configured to sit near a resected surface of a humerus, the humeral adapter tray comprising: a cavity; a central bore; and a distal face including a boss, the boss: (i) configured as an extension of the distal face, (ii) posteriorly offset from the central bore by at least 10 mm, and (iii) configured to engage a humeral stem; and a humeral liner comprising: a distal rim configured to sit within the cavity of the humeral adapter tray; and a concave articulating surface configured to mate with a convex articulating surface of a glenosphere. In an embodiment, the boss, in addition to being posteriorly offset, is superiorly offset from the central bore by at least 8 mm. In an embodiment, the reverse shoulder a humeral stem which engages the boss.

Abstract:
This disclosure describes devices and methods for performing spinal surgical procedures. In some embodiments, a method may include positioning at least a portion of at least one surgical instrument in at least one naturally occurring orifice of a human by a user. In some embodiments, a method may include accessing an interior space of the human using at least one of the surgical instruments. The method may include performing at least a portion of a spinal surgical procedure using at least one of the surgical instruments positioned in at least one of the naturally occurring orifices of the human. The method may include removing at least one of the surgical instruments from at least one of the naturally occurring orifices upon completion of at least a portion of the spinal surgical procedure.
Abstract:
One embodiment of the present invention relates to a knee prosthesis system with at least a first tibial portion element (a tibial insert or a tibial insert trial) and a second tibial portion element (a tibial insert or a tibial insert trial), wherein each of the first tibial portion element and the second tibial portion element has a different slope. Another embodiment of the present invention relates to a method of implanting a knee prosthesis, wherein the method utilizes at least a first tibial portion element (a tibial insert or a tibial insert trial) and a second tibial portion element (a tibial insert or a tibial insert trial), wherein each of the first tibial portion element and the second tibial portion element has a different slope.
Abstract:
One embodiment of the present invention relates to a reverse shoulder assembly. Another embodiment of the present invention relates to a reverse shoulder assembly method of use. In one example, a reverse shoulder assembly of the present invention may be provided such that the reverse shoulder assembly alters the abduction force created by a patient's deltoid to a forward flexion force. In one example, a reverse shoulder assembly of the present invention may be provided such that the reverse shoulder assembly alters the abduction force created by a patient's deltoid to an external rotation force. In one example, a reverse shoulder assembly of the present invention may be provided such that the reverse shoulder assembly alters the abduction force created by a patient's deltoid to an external rotation force and a forward flexion force.
Abstract:
Methods, systems, devices and tools for placing bone stabilization components in a patient are provided. The systems and devices have a reduced number of discrete components that allow placement through small incisions and tubes. More particularly, the present invention is directed to screws for use in systems and methods of treating the spine, which eliminate pain and enable spinal motion, which effectively mimics that of a normally functioning spine. Methods are also provided for installation of the screw and other subject systems.
Abstract:
Adjustable reverse shoulder prostheses are disclosed herein. A glenoid assembly includes a glenoid plate configured for fixation to a glenoid bone for a reverse shoulder prosthesis; a glenosphere configured for connection to the glenoid plate; and an adjustment plate, wherein the adjustment plate has a connection for directly engaging the glenosphere, and wherein the adjustment plate has an articulation for directly engaging the glenoid plate at a variable angular orientation. During a reverse total shoulder arthroplasty method, a glenoid plate is fixated to a glenoid bone; an adjustment plate, configured for interfacing with both the glenoid plate and a glenosphere, is locked to the glenoid plate, wherein the adjustment plate is configured for angular orientation or positional change relative to the glenoid plate; a glenosphere is connected to the adjustment plate; and an angular orientation and position of the glenosphere relative to the fixated glenoid plate is independently adjusted.
Abstract:
A rod reduction instrument for position a rod relative to a seat of a bone anchor in a spinal implant system is provided. The instrument includes three concentric cannulas with circumferentially aligned rod receiving portions formed therein. One cannula is movable with respect to another to lock and unlock the seat of a bone anchor to the rod reduction instrument. The rod to be reduced is positioned inside at least one of the rod receiving portion. One cannula is moved with respect to another to lock the seat of the bone anchor to the rod reduction instrument. Once locked to the bone anchor, the remaining cannula is moved to reduce the distance between the rod and the seat within at least one of the rod receiving portions. The distance between the rod and the seat is reduced until the rod is position inside the seat. A secondary instrument is inserted through a central bore of the rod reduction instrument to introduce a cap and lock the cap to the seat securing the rod to the bone anchor.
