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 alignment hole is configured for aligning the plate during an osteotomy procedure, while other alignment holes are configured for use after fracture reduction and receive K-wires to temporarily stabilize the fracture and 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.

What is claimed is: 1. A method of performing an osteotomy, comprising: a) drilling a K-wire through a portion of a bone; b) providing a bone plate with a first portion having an alignment hole, and a second portion; c) using the K-wire as a guide, positioning the bone plate over the K-wire, with t
What is claimed is: 1. A method of performing an osteotomy, comprising: a) drilling a K-wire through a portion of a bone; b) providing a bone plate with a first portion having an alignment hole, and a second portion; c) using the K-wire as a guide, positioning the bone plate over the K-wire, with the K-wire extending through the alignment hole, and advancing the plate over the K-wire so that a first portion of the plate contacts an aspect of the bone; d) securing the first portion of the bone plate to the bone; e) performing an osteotomy; and f) securing a second portion of the plate to the bone on a side of the bone opposite the osteotomy. 2. A method according to claim 1, wherein: said drilling is in relation to an anatomical landmark. 3. A method according to claim 2, wherein: said anatomical landmark is an articular surface. 4. A method according to claim 1, wherein: the bone is a distal radius bone. 5. A method according to claim 1, wherein: the osteotomy is performed proximal to where the first portion of the bone plate is secured to the bone. 6. A method according to claim 1, wherein: said drilling is parallel to the articular surface at end of the bone. 7. A method according to claim 1, wherein: said method is performed to correct a metaphyseal deformity. 8. A method according to claim 1, further comprising: removing the K-wire after the first portion of the plate is secured to the bone. 9. A method according to claim 1, wherein: said performing an osteotomy includes, cutting the bone to define a cut, and levering the second portion of the bone plate toward the bone on an opposite side of the cut from where the first portion of the bone plate is secured to the bone. 10. A method according to claim 9, wherein: said levering creates an open wedge in the bone. 11. A method according to claim 1, wherein: said alignment hole is oblong. 12. A method according to claim 1, wherein: the first and second portions are angled relative to each other. 13. A method of performing an osteotomy, comprising: a) drilling a K-wire through a portion of a bone; b) using the K-wire as a guide, positioning a bone plate over the K-wire and against an aspect of the bone; c) securing a first portion of the bone plate to the bone, wherein said securing a first portion includes inserting a plurality of pegs through threaded holes in the plate and into the bone, the pegs having threaded heads which lock relative to the threaded holes; d) performing an osteotomy; and e) securing a second portion of the plate to the bone on a side of the bone opposite the osteotomy. 14. A method according to claim 13, wherein: said securing a second portion includes inserting a plurality of non-locking screws through holes in the plate and into the bone. 15. A method of performing an osteotomy, comprising: a) drilling a K-wire through a portion of a bone, said drilling parallel to an articular surface at an end of the bone; b) using the K-wire as a guide, positioning a bone plate over the K-wire and against an aspect of the bone; c) securing a first portion of the bone plate to the bone; d) performing an osteotomy; and e) securing a second portion of the plate to the bone on a side of the bone opposite the osteotomy. 16. A method according to claim 15, wherein: the first and second portions are angled relative to each other. 17. A method of performing an osteotomy, comprising: a) drilling a K-wire through a portion of a bone, said drilling parallel to an articular surface at an end of the bone; b) using the K-wire as a guide, positioning a bone plate over the K-wire and against an aspect of the bone; c) securing a first portion of the bone plate to the bone; d) performing an osteotomy; e) securing a second portion of the plate to the bone on a side of the bone opposite the osteotomy; and f) removing the K-wire after the first portion of the plate is secured to the bone. 18. A method according to claim 17, wherein: the first and second portions are angled relative to each other. 19. A method of performing an osteotomy, comprising: a) drilling a K-wire through a portion of a bone, said drilling parallel to an articular surface at an end of the bone; b) using the K-wire as a guide, positioning a bone plate over the K-wire and against an aspect of the bone; c) securing a first portion of the bone plate to the bone; d) performing an osteotomy, including cutting the bone to define a cut, and levering the second portion of the bone plate toward the bone on an opposite side of the cut from where the first portion of the bone plate is secured to the bone; and e) securing a second portion of the plate to the bone on a side of the bone opposite the osteotomy. 20. A method according to claim 19, wherein: said levering creates an open wedge in the bone. 21. A method according to claim 19, wherein: the first and second portions are angled relative to each other.
