FIELD: medicine.
SUBSTANCE: system for tibia angle changing for patient having knee osteoarthritis comprises an adjustable non-invasive implant and a drive member. The adjustable non-invasive implant comprises an adjustable actuator configured to fit inside the tibia longitudinal cavity and having an outer housing and an inner rod telescopically arranged in the outer housing. The outer housing is connectable to the first part of the tibia, and the inner rod is configured to be connected to the second part of the tibia. The second part of the tibia is at least partially separated from the first part of the tibia by means of osteotomy. The drive element comprises a permanent magnet and is adapted to remote actuation, in order to telescopically displace the inner rod relative to the outer housing. The system for bone angle changing includes an adjustable non-invasive implant and a drive member. The adjustable non-invasive implant comprises an adjustable actuator having an outer housing and an inner rod telescopically arranged in the outer housing. The outer housing is connected to the first anchor hole, and the inner rod is connected to the second anchor hole. The first anchor hole is configured to pass the first anchor to connect the adjustable actuator to the first part of the bone. The second anchor hole is configured to pass the second anchor to connect the adjustable actuator with the second part of the bone. The second part of the bone is at least partially separated from the first part of the bone by means of osteotomy. The drive element is adapted to remote actuation, in order to telescopically displace the inner rod relative to the outer housing. The adjustable non-invasive implant is adapted to be indefinite in angle relatively to at least one of the first or the second part of the bone when connected to both the first part and the second part of the bone.
EFFECT: prevention of adjustment angle loss.
