First Claim
Patent Images
1. A bone plate for bone fixation, comprising:
- first and second plate members structured to be placed under skin and each defining one or more openings configured to receive fasteners that secure the first and second plate members to portions of at least one bone; and
a joint connecting the first and second plate members and defining an angular disposition between the first and second plate members, the joint having (1) a pivotable configuration in which the angular disposition is adjustable by pivotal movement of the first plate member about two or more nonparallel axes, and (2) a fixed configuration in which the angular disposition is fixed,wherein the first and second plate members include respective concave and convex surfaces that are at least substantially complementary, and wherein the concave and convex surfaces are configured to slide on each other in the pivotable configuration of the joint.

17. A bone plate for fixation of the radius, comprising:
-
first and second plate members each defining one or more openings configured to receive fasteners for securing the first and second plate members to different portions of a radius bone, at least one of the first and second plate members having a nonplanar inner surface that is generally complementary to a distal surface region of the radius bone, such that the at least one plate member fits onto the radius bone; and a joint connecting the first and second plate members and defining an angular disposition between the first and second plate members, the joint having an adjustable configuration in which the angular disposition is adjustable and a fixed configuration in which the angular disposition is fixed, wherein the joint includes a threaded fastener, and wherein the joint is configured to be placed in the fixed configuration by rotation of the threaded fastener. - View Dependent Claims (18, 19, 20)

-
first and second plate members structured to be placed under skin and each defining one or more openings configured to receive fasteners that secure the first and second plate members to portions of at least one bone; and a joint connecting the first and second plate members and defining a relative angular disposition of the first and second plate members, the joint having (1) an adjustable configuration in which the relative angular disposition is adjustable by movement of at least one of the first and second plate members about two or more nonparallel axes, and (2) a fixed configuration in which the relative angular disposition is fixed, wherein the first and second plate members include respective concave and convex surfaces that are at least substantially complementary, and wherein the concave and convex surfaces are configured to slide on each other in the adjustable configuration of the joint. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
