Abstract: A tire inflation valve having anti-rotation features has an external valve seat, and includes a valve body, a valve stem extending through the length of the valve body, and anti-rotation features disposed interior to the valve body. The valve stem is configured to move relative to the valve body, such that a resilient seating surface disposed at a proximal end of the valve stem is displaced relative to a valve seat formed by an exterior surface of a proximal end of the valve body. The anti-rotation features may include a complementary slot and protrusion, a keyway and complementary protruding ridge, and/or complementary channels and lateral protrusions.

Abstract: A glenoid prosthesis includes a head portion and an anchor. The head portion includes a first surface adapted to contact a glenoid and an opposed second surface that is at least partially concave. The anchor extends from the first surface of the head portion and terminates at a distal end. At least one first circular member is disposed between the head portion and the distal end of the anchor and encircle the anchor. At least one second circular member is disposed between the head portion and the distal end of the anchor and encircles the anchor. The at least one first circular member is adapted to engage cortical bone of a glenoid and the at least one second circular member is adapted to engage cancellous bone of a glenoid when the glenoid prosthesis is implanted.

Abstract: An inflation valve for a tubeless tire may include a valve body defining a cavity having a proximal opening and a distal opening. A valve stem extends through the cavity and includes a plug at a proximal end of the valve stem. The proximal opening of the cavity is defined by a beveled surface, and an outer diameter of the beveled surface is larger than an inner diameter of the valve body. The valve is transitionable between: a) a closed position, where a resilient surface of the plug engages the beveled surface to seal the cavity, and b) an open position, where the resilient surface of the plug is spaced from the beveled surface to unseal the cavity.

Abstract: A method of fixating a prosthesis to a glenoid is disclosed. The method includes forming a bore in the glenoid; positioning the prosthesis adjacent the glenoid, where the prosthesis includes a head portion and an anchor extending from a rear surface of the head portion; wherein the anchor includes a first fin and a second fin proximal of the first fin; advancing the anchor into the bore until the first fin is implanted within cancellous bone; and further advancing the anchor in the bore until a proximal-facing surface of the second fin is implanted within cancellous bone and abuts cortical bone.

Abstract: Provided is a glenoid implant system that includes a tray component that includes a bone-facing surface and a bearing-facing surface on opposite side of the bone-facing surface; and a bearing component that includes an articulating surface that is generally concave and a back side on opposite side of the articulating surface that is generally convex, wherein the articulating surface is configured for engaging a convex humeral head and the back side is configured for engaging the bearing-facing surface of the tray component thus enabling the bearing component to slide about on the tray component while the convex humeral head articulates against the articulating surface.

Abstract: Provided is a slot anchor guide that includes a medial portion and a lateral portion, the medial portion includes a medial projection configured to span a slot of a fixation plate, where the slot anchor guide is configured to guide an anchor through a predetermined position of a slot of the fixation plate and to mate with the fixation plate to allow a surgeon to place the fixation plate on a bone face by manipulating the lateral portion. Also provided is a tuberosity fracture plate that includes a tuberosity end having a first portion configured to overlay a first tuberosity and a second portion opposite the first portion, a distal portion coupled with and extending away from the tuberosity portion.
