1. A method of changing a bone angle, the method comprising:
creating an open wedge osteotomy between a first portion and a second portion of a tibia of a patient, wherein the first portion of the tibia remains attached to the second portion of the tibia;
creating a first cavity in the tibia by removing bone material along a first axis extending from a tibial plateau of the tibia along a medullary canal of the tibia;
inserting an excavation device through an opening in the tibial plateau and into the first cavity;
using the excavation device, forming a second cavity to one side of the first cavity;
removing the excavation device from the first cavity;
inserting a non-invasively adjustable osteotomy device into the first cavity, the non-invasively adjustable osteotomy device comprising:
an outer housing;
an inner shaft telescopically disposed within the outer housing; and
a driving element configured to be operable to displace the inner shaft in relation to the outer housing;
securing the non-invasively adjustable osteotomy device within the second cavity;
coupling one of the outer housing or the inner shaft to the first portion of the tibia;
coupling the other of the outer housing or the inner shaft to the second portion of the tibia; and
operating the driving element displace the inner shaft relative to the outer housing, thereby changing an angle between the first portion and the second portion of the tibia.
