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).
