摘要： A thighbone shaft has a pole and a bolt. The pole defines an inclined threaded hole therein. Tooth portions are respectively formed at opposite sides of the pole. A head is arranged on a front portion of the pole. A sleeve is provided on the head. A threaded portion is formed on the bolt and is retained in the inclined threaded hole for engaging the bolt and the pole. The thighbone shaft is assembled easily, reduces planting area and replacement cost, decreases stress force, and promotes planting fixedness.

摘要： The invention relates to modular hip joint prosthesis and an assembling method thereof. The modular hip joint prosthesis includes a stem component, a proximal body module and lock component. The proximal body module assembles with the stem component and includes a first curved surface component and a second curved surface, wherein the radius of curvature of the first curved surface component is different from the radius of curvature of the second curved surface component. The lock component is used to encase the first curved surface component and the second curved surface for locking up both components.

摘要： An anti-subsidence dynamic hip screw comprises of a barrel having a connection portion and a tube-type extending portion angled a predetermined angle with the connection portion, and a first long groove and a first limit portion disposed at the inner wall of the extending portion respectively; a lag screw having an inside end disposed threading screw at its outer edge and a outside end with a predetermined length passed through in the extending portion by the way of reciprocation; a second long groove and a second limit portion disposed at the lag screw respectively related to the first long groove and the first limit portion, each first limit portion and second limit portion used for preventing the lag screw from rotating inside the extending portion; a blade piece with a predetermined length simultaneously passed through and retained in the first long groove and the related second long groove; a compressing screw having an inside end screwed with the outside end of the lag screw and an outside end retained in the outside end of the extending portion. The above structure is not only easy to assembly, especially for the effect of decreasing the subsidence of the femoral head, but also makes the effect more obvious when using for the hip fracture of the osteoporosis body.
