ADJUSTABLE DEVICES FOR TREATING ARTHRITIS OF THE KNEE

摘要

A method of changing a bone angle includes creating an osteotomy in a tibia of a patient; creating a cavity in the tibia by removing bone material; placing a non-invasively adjustable implant into the cavity, the non-invasively adjustable implant comprising an adjustable actuator having an outer housing and an inner shaft, telescopically disposed in the outer housing, and a driving element configured to be remotely operable to telescopically displace the inner shaft in relation to the outer housing; coupling one end of the implant to the first portion of the tibia; coupling the other end of the implant to the second portion of the tibia; and remotely operating the driving element to telescopically displace the inner shaft in relation to the outer housing to changing an angle between the first portion and second portion of the tibia.
