At least the first end portion can protrude relative to the connection portion such that it is at least partly receivable in a first recess formed in the first bone region. The first end portion can be in the form of an end cup and can be fixed to the first bone region by a fixation device such as a screw. A head of the screw can sit within the end cup. The second end portion can be similar to the first end portion or alternatively may comprise a hook, blade or staple. ## Claims ### Claim 1 An orthopaedic system for fixing between first and second regions of bone separated by a growth plate, comprising: a bone screw having a threaded shaft and a head; and a device including a first end portion adapted and configured to fix to the first bone region; a second end portion adapted and configured to fix to the second bone region; and a connection portion connected between the first and second end portions and having an underside to extend across an outer surface of the bone that includes the growth plate between the first and second bone regions, wherein, at least the first end portion includes an open cup that protrudes relative to the connection portion such that it is at least partly receivable in a first recess in the first bone region, the open cup having an unthreaded interior surface adapted and configured to receive therein the head of said bone screw; and wherein the open cup defines a first opening adapted and configured to receive the threaded shaft for fixing said device to the first bone region, the open cup permitting pivotal rotation of said fixed bone screw relative to said device. ### Claim at position 2 2-5. (canceled) ### Claim 6 (depends on 1) The device of claim 1, wherein the connection portion has an inner surface that is adapted to face in an inwards direction towards an outer surface of the bone, and wherein the first end portion protrudes in the inwards direction. ### Claim 7 (depends on 6) The device of claim 6, wherein a first shoulder region is formed at an interface between an inner surface of the first end portion and the inner surface of the connection portion. ### Claim 8 (canceled) ### Claim 9 (depends on 7) The device of claim 7, wherein the first shoulder region defines an angle of at least 90 degrees. ### Claim at position 7 10-27. (canceled) ### Claim 28 (depends on 1) The system of claim 1, wherein the second end portion comprises a hook. ### Claim 29 (depends on 28) The device of claim 28, wherein the hook is adapted to hook around a portion of the second bone region when the first end portion is located in the first recess. ### Claim 30 (depends on 28) The device of claim 28, wherein the hook is adapted to at least partially locate in a second recess formed in the second bone region. ### Claim 31 (depends on 28) The device of claim 28, wherein the hook bends at an angle relative to the connection portion of at least about 150 degrees. ### Claim 32 (depends on 28) The device of claim 28, wherein the hook comprises first and second prongs that each taper in width towards a distal end of the hook. ### Claim 33 (depends on 28) The device of claim 28, wherein the hook comprises two or more prongs. ### Claim 34 (depends on 1) The device of claim 1, wherein the second end portion comprises a staple. ### Claim 35 (depends on 1) The device of claim 1, wherein the second end portion comprises a blade. ### Claim at position 16 36-37. (canceled) ### Claim 38 (depends on 1) The device of claim 1, wherein the first and second end portions are rigid and the connection portion is non-rigid. ### Claim 39 (depends on 38) The device of claim 38, wherein the connection portion comprises a flexible link. ### Claim 40 (depends on 39) The device of claim 39, wherein the flexible link is a flexible tape or band. ### Claim 41 (depends on 40) The device of claim 40, wherein the first and second end portions comprise slots and the flexible link connects to the first and second end portions by extending into the slots. ### Claim at position 21 42-45. (canceled) ### Claim 46 A method of guiding growth of a bone, the bone including first and second regions of bone separated by a growth plate, the method comprising: locating a first end portion of an orthopaedic device in a first recess at the first bone region; and locating a second end portion of the orthopaedic device at the second bone region; wherein the orthopaedic device has a connection portion connected between the first and second end portions, and wherein, the first end portion protrudes relative to the connection portion such that the connection portion extends across an outer surface of the bone between the first and second bone regions when the first end portion is located in the first recess and the second end portion is located at the second bone region, and wherein the first end portion defines a first opening to receive a first fixation device and the method comprises fixing the first end portion to the first bone region by extending the first fixation device through the first opening and into the first bone region. ### Claim 47 (depends on 46) The method of claim 46, comprising locating the second end portion in a second recess at the second bone region, wherein the second end portion protrudes relative to the connection portion. ### Claim 48 (depends on 47) The method of claim 47, wherein the second end portion defines a second opening to receive a second fixation device and the method comprises fixing the second end portion to the second bone region by extending the second fixation device through the second opening and into the second bone region. ### Claim 49 (depends on 46) The method of claim 46, wherein the second end portion comprises a hook. ### Claim 50 (depends on 46) The method of claim 46, wherein the second end portion comprises a staple. ### Claim 51 (depends on 46) The method of claim 46, wherein the second end portion comprises a blade. ### Claim at position 28 52-54. (canceled) ### Claim 55 An orthopaedic device for fixing between first and second regions of bone separated by a growth plate, the orthopaedic device comprising: a first end portion to fix to the first bone region; a second end portion to fix to the second bone region; and a connection portion connected between the first and second end portions to extend across an outer surface of the bone between the first and second bone regions, wherein, the first end portion defines a first opening to receive a first fixation device to fix the orthopaedic device to the first bone region; wherein, the second end portion defines a second opening to receive a second fixation device to fix the orthopaedic device to the second bone region; wherein the first end portion is configured to allow pivotal rotation of the first fixation device relative to the orthopaedic device when the first fixation device is received in the first end portion; and wherein the second end portion is configured to prevent pivotal rotation of the second fixation device relative to the orthopaedic device when the second fixation device is received in the second end portion.
