A method for compressing at least a first and second bones comprising:aligning the first and second bones in a desired alignment;inserting a screw member into a borehole extending through the aligned first and second bones, the screw member comprising an elongated body extending from a first end to a second end, wherein the first elongated body includes threads near the first end and a head at the second end;inserting a first transverse element into the first bone or the second bone transversely to a length of the screw member at a first position thereby engaging the elongated body of the screw member such that the screw member can be rotated with respect to the first transverse element; androtating the screw member to compress the first and second bones.2. The method of claim 1 , wherein the first and second bones that are compressed are in a human foot.3. The method of claim 1 , wherein step of aligning the first and second bones comprises the step of: inserting a guide wire through the first and second bones.4. The method of claim 1 , wherein the screw member is cannulated and the step of inserting the screw into the borehole comprises:mounting the screw member on a guide wire in the borehole; andinserting the screw into the borehole on the guide wire.5. ...

INTRAMEDULLARY ANKLE TECHNIQUE AND SYSTEM

A prosthesis suited for orthopedic implantation comprising a modular intramedullary rod that provides intramedullary guidance and that supports an artificial joint surface that can articulate with another artificial joint surface in various ways. Intramedullary guidance systems and methods introduce some and/or all surgical tools and ankle prostheses components through the tibia, using minimal invasive exposure. The systems and methods align the talus and tibia for the installation of one or more ankle prostheses components, and also maintain that alignment during the installation using intramedullary guidance. 1. An intramedullary rod , comprising:a plurality of modular components sized and configured to be disposed in an intramedullary canal;wherein said modular components are configured to be connected to each other in situ; andwherein the distal-most modular component is a base component configured to engage an alignment guide.2. The intramedullary rod of claim 1 , wherein the intramedullary canal is in a tibia.3. The intramedullary rod of claim 1 , wherein the alignment guide is configured for coronal claim 1 , transverse claim 1 , and sagittal adjustments.4. The intramedullary rod of claim 3 , wherein the alignment guide is configured to translate said coronal claim 3 , transverse claim 3 , and sagittal adjustments to a cutting guide.5. The intramedullary rod of claim 3 , wherein the alignment guide comprises at least one hole to place at least one pin claim 3 , and wherein the pin is used to translate said coronal claim 3 , transverse claim 3 , and sagittal adjustments from the alignment guide to a cutting guide.6. A method claim 3 , comprising:inserting a plurality of modular components in an intramedullary canal;connecting said plurality of modular components in situ to form a single intramedullary rod component; andconnecting a distal end of said intramedullary rod component to an alignment guide.7. The method of claim 6 , wherein said intramedullary canal ...
