Multi-walled Nanotube (MWNT) can be carbon nanotubes/nanotubules less than 500nm in diameter or less than 100nm in diameter, nested in an arrangement wherein one or more smaller tubule/nanotube may be positioned inside a larger tubule/nanotube. The nesting arrangement may be concentric, non-concentric, or a combination thereof. (Fig. 3 below) Multiples walls of the Multi-walled Nanotube may have equal lengths or may be of unequal lengths relative to each other. |

Alternatively, or in addition, a user may use the modification module 2208 to modify a predefined osteotomy procedure. The user may add, remove, or modify steps and the instrumentation used in the osteotomy procedure to create a patient specific osteotomy procedure. In this manner, a user may configure features of a selected template cutting guide model 1834 or modified template cutting guide model and/or osteotomy procedure specific to a patient specific osteotomy procedure the surgeon is planning for the patient. As used herein, "patient specific osteotomy procedure" refers to an osteotomy procedure that has been adjusted, tailored, modified, or configured to specifically address the needs or desires or a particular patient. In certain aspects, one patient specific osteotomy procedure may be useable in connection with only one patient. In other aspects, one patient specific osteotomy procedure may be useable with a number of patients having a particular class of characteristics. |

The subject technology generally relates to an orthopedic implant that incorporates carbon nanotubes on a bone-facing side of the implant that can generate an electric charge to stimulate bone in-growth. Compressive forces acting perpendicular to the tubules generate an electrical charge. Additionally, a charge may be generated via compression, torsion, shear, and/or combination of these. |
