摘要： A cortical bone screw assembly comprising a shaft with a threaded section (2) and a cutting and self-tapping end section (3). The assembly includes a nut (14) which includes a resilient body (16). The resilient body (16) can expand to allow translational movement of the nut (14) along the shaft, but when such radial expansion is prevented so is such translational movement. However, the nut (14) can still be moved along the shaft by rotation on the thread (2). This enables the nut (14) to be advanced rapidly along an exposed length of shaft, but when it enters a restricted volume which prevents expansion of the resilient body (16), further advance can only be achieved by relative rotation.

摘要： An adjustable two-dimensional joint for use in hip compression screw assemblies, allows for relative alignment of the lag screw and angle plate, even when these components are effectively fitted to the respective bone sections. The joint has first and second elements (2, 4), formed with complementary male and female cylindrical surfaces (10, 12), which define the plane of adjustment. The first element (2) also defines a hinge point (6) at the axis of the male cylindrical surface (10), and the second element (4) includes a fulcrum (8) extending to the axis of the female cylindrical surface (12). A setting device (20) extends between the two elements (2, 4), which can be extended or contracted to alter the angle subtended at the hinge point/fulcrum (6, 8).

摘要： A two-dimensional joint for use in hip compression screw assemblies has first and second elongate elements (2, 4) formed with complementary male and female surfaces (10, 12) defining the plane of adjustment. A setting member (20) extends from a pivot point on the first element (2) into the second element (4) along a set axis (18) inclined to the axis of the second element (4), and adjustably coupled thereto. Such adjustment alters the angle between the elements (2, 4) when the cylindrical surfaces (10, 12) are in sliding engagement.
