Systems, devices and methods are disclosed for treating fractures and other bone maladies. The systems, devices and methods may include one or both of a stabilizing structure, such as an implant, bone plate, or other device and a fastening assembly, such as a lag screw and compression screw assembly. The stabilizing structure in some embodiments has a proximal section with a transverse aperture and a cross-section that may be shaped to more accurately conform to the anatomical shape of cortical bone and to provide additional strength and robustness in its lateral portions, preferably without requiring significant additional material. The fastening assembly may be received to slide, in a controlled way, in the transverse aperture of the stabilizing structure. In some embodiments, the engaging member and the compression member are configured so that the compression member interacts at least indirectly with the stabilizing structure and a portion of the engaging member to enable controlled movement between the first and second bone fragments. This configuration is useful for, among other things, compressing a fracture.

The invention claimed is: 1. A method for treating bone maladies, comprising: associating a stabilizing structure with an exterior of a first bone portion, the stabilizing structure comprising a first transverse aperture; engaging an engaging member with a second bone portion; at least partially inserting the engaging member through the first transverse aperture; and passing a compression member at least partially through the first transverse aperture; wherein the compression member at least indirectly interacts with the stabilizing structure; wherein the compression member contacts the second bone portion; and wherein the compression member contacts and interacts with an external surface of the engaging member to move the second bone portion towards the first bone portion. 2. The method for treating bone maladies of claim 1, further comprising using the compression member to facilitate a sliding movement of the engaging member with respect to the stabilizing structure, wherein the compression member at least indirectly interacts with the stabilizing structure to facilitate controlled movement between the first and second bone portions. 3. The method for treating bone maladies of claim 1, further comprising: associating a guide with the stabilizing structure; and using the guide to guide the movement of at least one bone preparation instrument. 4. The method for treating bone maladies of claim 3, wherein the guide is used to guide the movement of a plurality of bone preparation instruments. 5. The method for treating bone maladies of claim 3, wherein the guide is used to guide the movement of the at least one bone preparation instrument after the stabilizing structure has been associated with the first bone portion. 6. The method for treating bone maladies of claim 5, wherein the engaging member is engaged with the second bone portion after the stabilizing structure is associated with the first bone portion and after the guide is used to guide the movement of the at least one bone preparation instrument. 7. The method for treating bone maladies of claim 1, wherein the engaging member is at least partially inserted through the first transverse aperture after the engaging member is associated with the second bone portion. 8. The method for treating bone maladies of claim 2, wherein using the compression member to facilitate a sliding movement of the engaging member facilitates compressing the second bone portion with respect to the first bone portion. 9. The method for treating bone maladies of claim 1, wherein the engaging member comprises a channel and wherein the compression member at least partially nests within the channel. 10. The method for treating bone maladies of claim 9, wherein the engaging member comprises threads formed in the channel, and wherein the compression member interacts with the threads to move the second bone portion towards the first bone portion. 11. A method for treating bone maladies, comprising: associating a stabilizing structure with an exterior of a first bone portion, the stabilizing structure comprising a transverse aperture; engaging an engaging member with a second bone portion, the engaging member comprising an exterior channel and a cooperation structure located in the channel; at least partially inserting the engaging member through the transverse aperture; and passing a compression member at least partially through the transverse aperture; wherein the compression member at least indirectly interacts with the stabilizing structure; and wherein the compression member at least partially nests within the channel and interacts with the cooperation structure of the engaging member to move the second bone portion towards the first bone portion. 12. The method for treating bone maladies of claim 11, wherein the cooperation structure comprises threads, and further comprising rotating the compression member to move the second bone portion towards the first bone portion. 13. The method for treating bone maladies of claim 11, wherein the engaging member is at least partially inserted through the transverse aperture after the engaging member is engaged with the second bone portion.
