Abstract: A display device and a bezel thereof are provided. The display device includes a display panel and a bezel. The display panel has a first surface and a second surface. The first surface includes at least one pixel pad section, and the second surface includes at least one circuit pad section. The bezel includes a first surface connecting portion, a second surface connecting portion and at least one conductive wire. The edge of the display panel having the pixel pad section and the circuit pad section is accommodated between the first surface connecting portion and the second surface connecting portion. Each conductive wire has a first end and a second end. The first end is disposed on the first surface connecting portion and the second end is disposed on the second surface connecting portion. The part of the first connecting portion having the first end corresponds to the pixel pad section, and the part of the second connecting portion having the second end corresponds to the circuit pad section.

Abstract: A bone screw of minimally invasive fixation device for lumbar comprises a positioning casing and a screw body. The positioning casing includes a rod securing base and an alignment portion, both of which are integrally formed; an annular notch is formed between them. The alignment portion has at least two pairs of rod alignment openings in a bulb-shaped or keyhole-shaped form with an upper portion larger than a lower portion. Two longitudinal notches extend from near the top across the alignment openings to the rod securing base. The screw body includes a spherical head and a screw rod; the outer diameter of the spherical head is larger than that of the screw rod. The screw body is rotatably connected to the bottom portion of the positioning casing; the spherical head of the screw body is arranged in the spherical pit of the rod securing base.

Abstract: The percutaneous minimally invasive pedicle fixation system herein comprises a bone screw and a hook-rod, wherein the bone screw includes a positioning casing and a screw body. The positioning casing comprises securing base, an alignment casing and a screw body passage. The securing base includes a through hole at the bottom and two openings arranged opposite to each other in the wall. The alignment casing has a wall portion and a volume reduce portion, wherein the wall portion is configured with an elongate opening and the volume reduced portion is a portion with part of the wall removed to recede from the outer surface of the securing base and a guide opening formed in the volume reduced portion. The positioning casing further includes a first easy breaking portion between the alignment casing and the securing base so that the alignment casing can be removed from the positioning casing.

Abstract: A method for filling a bone defect in a subject in need thereof is disclosed. The method includes heating a bone cement composition at a first temperature where the bone cement composition is fluidic, and delivering an effective amount of the fluidic bone cement composition at a second temperature to the bone defect thereby filling the bone defect and allowing the fluidic bone cement composition to solidify, the second temperature being sufficiently high for maintaining the bone cement composition fluidic without causing thermal necrosis. Also disclosed are systems for carrying out the method.

Abstract: A bone anchor comprises a screw body and a flange, which are joined together in a way to keep their rotation independent from each other. In implanting the screw body into a bone, the flange does not rotate to prevent twisting and/or snarling of the suture in wounded bone from occurring.
