The method includes the steps of using at least one bone hook that engages the interior of the bone to apply a counterforce to the bone plate installation forces. ## Claims ### Claim 1 A bone plate installation kit comprising: a bone plate and first and second bone hooks; the bone plate having a central portion located between a first end portion and a second end portion; each of the end portions defining at least one fastener opening; the central portion defining an elongated slot having a length between slot ends and a minimum width; each bone hook having a shank and a hook end; the shank of each bone hook being sized to allow both shanks to be located in and move around in the elongated slot at the same time and move independently of the other to point the hook ends in substantially opposite directions; and each shank having a maximum width dimension that is no greater than two-thirds of the minimum width of the elongated slot. ### Claim 2 (depends on 1) The kit of claim 1, wherein the elongated slot has a length that is at least two times and at most eight times the minimum width of the elongated slot. ### Claim 3 (depends on 1) The kit of claim 1, wherein the elongated slot has a length that is greater than three times a diameter of the fastener opening in one of the end portions. ### Claim 4 (depends on 1) The kit of claim 1, wherein the plate defines a plurality of fastener openings in each end portion. ### Claim 5 (depends on 1) The kit of claim 1, wherein the hook end of at least one of the bone hooks is selectively extendable to an extended condition and selectively retractable to a retracted condition. ### Claim 6 (depends on 5) The kit of claim 5, wherein the selectively extendable and selectively retractable hook end is biased toward the retracted condition. ### Claim 7 (depends on 5) The kit of claim 5, wherein the shank of the at least one of the bone hooks has a curved tip through which the hook end extends and into which the hook end retracts. ### Claim 8 (depends on 5) The kit of claim 5, wherein the hook end is connected to a plunger. ### Claim 9 (depends on 5) The kit of claim 5, further comprising a latch that holds the hook end in the extended condition. ### Claim 10 (depends on 5) The kit of claim 5, wherein the hook end is rotatable with respect to the shank; the hooks end having a portion in the form of one of a thread, a screw tip, a corkscrew, and a pig tail. ### Claim 11 (depends on 10) The kit of claim 10, further comprising a plunger that selectively rotates the hook end. ### Claim 12 A method of installing a bone plate over a bone fracture comprising the steps of: positioning a first bone hook through a slot in a bone plate; the bone hook having a shank and a hook end; moving the hook end into an interior of one bone end on one side of a fractured bone through a fractured end of the fractured bone; and supporting the one bone end on one side of the fracture of a fractured bone with the first bone hook by providing an outward counterforce working against an inward force created during installation of a bone fastener into the one bone end through the bone plate. ### Claim 13 (depends on 12) The method of claim 12, further comprising the step of extending the hook end from a retracted position to an extended position with respect to the shank. ### Claim 14 (depends on 13) The method of claim 13, further comprising the step of rotating the hook end to screw it into the interior of the one bone end. ### Claim 15 (depends on 13) The method of claim 13, wherein the shank has a curved tip and the hook end is connected to a plunger with a shaft; the method further comprising the step of bending at least a portion of the hook end and shaft through the curved tip as the hook end is moved from the retracted position to the extended position. ### Claim 16 A method of installing a bone plate over a bone fracture comprising the steps of: inserting a first self-expanding bone anchor into an interior of one bone end on one side of a fractured bone through a fractured end of the fractured bone; inserting a second self-expanding bone anchor into an interior of the other bone end on the other side of the fractured bone through the other fractured end of the fractured bone; connecting the first and second self-expanding bone anchors together with a connector; and moving the bone ends together with force on the connector. ### Claim 17 (depends on 16) The method of claim 16, further comprising the step of supporting the one bone end by providing an outward counterforce on the connector that works against an inward force created during installation of a bone fastener into one of the bone ends through a bone plate. ### Claim 18 (depends on 16) The method of claim 16, wherein each of the self-expanding bone anchors is inserted into the bone end in a collapsed condition and allowed to self expand to an expanded condition.
