Anatomical distal radius fracture fixation plate and methods of using the same
First Claim
1. A fixation plate, comprising:
- a substantially rigid plate defining a first set of threaded peg holes adapted to individually receive fixation pegs therethrough and at least one non-threaded first alignment hole, each of said peg holes having a first diameter, and said at least one first alignment hole having a second relatively smaller diameter sized to closely receive a K-wire, each said at least one first alignment hole being located between peg holes.

Abstract
A fixation plate includes a set of threaded peg holes adapted to individually receive fixation pegs therethrough and non-threaded alignment holes having a relatively smaller diameter than the peg holes and preferably sized to closely receive a K-wire. The alignment holes are located between the peg holes. One peg hole is configured for aligning the plate during an osteotomy procedure, while other peg holes are configured for use after fracture reduction and receive K-wires to temporarily secure the plate to the bone and determine whether pegs inserted through adjacent respective peg holes will be properly located before drilling relatively larger holes for such pegs.

10. A fixation plate, comprising:
a substantially rigid plate having a body and a head, with said head angled upward relative to said body, said head defining a first set of longitudinally displaced threaded peg holes and a first non-threaded alignment hole substantially smaller in diameter than said peg holes and laterally displaced between two peg holes of said first set of peg holes. - View Dependent Claims (11, 12, 13, 14)

21. A substantially rigid fixation plate for stabilization of a distal radius bone fracture, comprising:
-
a) an elongate body portion;
b) a transverse head portion angled relative to said body portion, wherein said head and body portions are sized for use over the distal radius bone fracture; and
c) stabilization means to prevent said head portion from rocking on the distal radius prior to mechanically coupling said head portion to the bone. - View Dependent Claims (22, 23, 24, 25)

26. A system for fracture fixation of the distal radius, comprising:
-
a) a plate having a first portion and a second portion angled relative to said first portion, said first portion defining at least one screw hole, and said head defining a plurality of threaded peg holes and at least one substantially smaller non-threaded alignment hole situated between two adjacent peg holes;
b) at least one screw sized for insertion into said at least one screw hole;
c) a plurality of pegs each having a threaded head and a shaft, said pegs sized insertion into said peg holes; and
d) at least one K-wire, wherein said alignment hole is sized to closely receive said K-wire. - View Dependent Claims (27)

28. A method for treating a distal radius fracture, comprising:
-
a) reducing the fracture;
b) positioning a volar plate over the fracture, the plate including a body portion and a head portion angled relative to the body portion, the plate including a plurality of non-threaded alignment holes sized to closely receive a K-wire;
c) drilling K-wires through alignment holes of the plate and into the radius bone both proximal and distal of the fracture to temporarily secure the plate to the bone;
d) examining whether the location of the drilled K-wires is correct;
e) if the location is incorrect, removing the K-wires and relocating at least one of the plate and K-wires, and repeating steps c) and d); and
f) if the location is correct, more permanently securing the plate to the bone. - View Dependent Claims (29, 30, 31)

32. A method of performing correction of a deformity at a metaphysis of a long bone, comprising:
-
a) drilling a K-wire substantially parallel to an articular surface of the long bone such that one end of the K-wire is located within or through the bone and the other end of the K-wire is free;
b) providing a plate having a longitudinally displaced body and head portions which are angled relative to each other, the head portion including an alignment hole sized to closely receive the K-wire;
c) at the alignment hole, sliding the plate over the free end of the K-wire;
d) coupling the head portion to the bone distal of the fracture; and
e) cutting the bone at or adjacent the metaphysis;
f) levering the body portion of the plate to reorient the metaphysis relative to a diaphyseal portion of the long bone; and
g) coupling the body portion of the plate to the long bone. - View Dependent Claims (33, 34, 35, 36)
