Systems and related methods for changing the angle of a bone of a subject, the system may include a non-invasively adjustable implant configured to be placed inside a cavity within the bone. The non-invasively adjustable implant may couple to a first portion of bone and a second portion of bone that is separated or separable from the first portion of bone, such that non-invasive elongation of the adjustable implant causes movement of the first portion of bone and the second portion of bone apart angularly. The system may include an anchor configured to couple the non-invasively adjustable implant to bone. The non-invasively adjustable implant may include an anchor hole configured to receive the anchor therein.

A system for surgical planning and assessment of spinal deformity correction is provided that has a spinal imaging system and a control unit. The spinal imaging system is configured to collect at least one digitized position of one or more vertebral bodies of a subject. The control unit is configured to receive the at least one digitized position, and calculate, based on the at least one digitized position, an optimized posture for the subject. The control unit is configured to receive one or more simulated spinal correction inputs, and based on the inputs and optimized posture, predict an optimal simulated postoperative surgical correction.

Systems and methods for adjusting a curvature of a spine are provided. The systems may include an implant body, an actuator coupled to the implant body, a sensor configured to detect a parameter indicative of a biological condition, a transceiver, and a controller. The transceiver may be configured to transmit data associated with the parameter to an external remote control and receive instructions from the external remote control. Finally, the controller is configured to move the actuator in response to the instructions from the external remote control, wherein the actuator adjusts the implant body. The methods may include measuring a parameter indicative of a biological condition; transmitting data associated with the parameter from the implantable device to an external remote control; transmitting instructions from the external remote control to the implantable device; and actuating the implantable device in response to the instructions from the external remote control.

A prosthetic device for use as an artificial meniscus is disclosed. The prosthetic device restores stress distribution, stability, and function to the knee joint after removal of the damaged natural meniscus. In some embodiments, the prosthetic device includes an anti-migration feature that inhibits extreme movement within the joint while permitting free floating over a significant range. In one aspect, the anti-migration feature is an enlarged anterior structure or a posterior meniscus remnant engaging channel while in another aspect, the anti-migration feature includes a tethering member. Still further, removable radiopaque features are provided to enhance trialing of the implant prior to final implantation within the joint.

A method of changing a bone angle includes creating an osteotomy between a first portion and a second portion of a tibia of a patient; creating a cavity in the tibia by removing bone material along an axis extending in a substantially longitudinal direction from a first point at the tibial plateau to a second point; 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 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 remotely operating the driving element to telescopically displace the inner shaft in relation to the outer housing, thus changing an angle between the first portion and second portion of the tibia.

In one embodiment, an adjustable implant system includes a bone anchor having first and second ends, a bone engagement surface adjacent the first end, and a housing extending between the first and second ends. The adjustable implant system can further include a non-invasively actuatable driving element within the housing and coupled to an adjustment component configured to couple to a flexible elongate tension member which is capable of engaging a patient's soft tissue (e.g., rotator cuff or ACL). Non-invasive actuation of the driving element can cause the adjustment component to change the amount of tension on the flexible elongate tension member and consequently on the patient's soft tissue. The adjustable implant system can include an external adjustment device configured to be placed on or adjacent the patient's skin and comprising at least one energy transferring component configured to energize/actuate the driving element inside the housing of the adjustable implant.

A system, and method of using the system, for changing the angle of a bone of a subject is provided by the present disclosure. In one embodiment the system includes a non-invasively adjustable implant configured to be placed inside a longitudinal cavity within the bone and comprising an outer housing and an inner shaft telescopically disposed in the outer housing, at least one of the outer housing and inner shaft associated with a first anchor hole and a second anchor hole, the first anchor hole configured to pass a first anchor for coupling the adjustable implant to a first portion of bone and the second anchor hole configured for to pass a second anchor for coupling the adjustable implant to the first portion of bone, the inner shaft configured to couple to a second portion of bone that is separated or separable from the first portion of bone, such that non-invasive elongation of the adjustable implant causes the inner shaft to extend from the outer housing and to move the first portion of bone and the second portion of bone apart angularly; a driving element configured to be remotely operable to telescopically displace the inner shaft in relation to the outer housing; and wherein the first anchor hole is configured to allow the first anchor to pivot in at least a first angular direction and the second anchor hole is configured to allow the second anchor to translate in at least a first translation direction.

In one embodiment, a non-invasively adjustable spinal system for treatment of a subject having spondylolisthesis includes a first implantable actuator having at least one anchoring structure, the anchoring structure configured to facilitate securement of the first implantable actuator to a portion of the sacrum of the subject. The non-invasively adjustable spinal system can further include an adjustment element, configured to be coupled to the first implantable actuator, the adjustment element having an engagement structure configured to engage at least one transverse process of a lumbar vertebra of the subject. The non-invasively adjustable spinal system can further include a driving element, wherein remote activation of the driving element causes movement of the adjustment element in relation to the first implantable actuator.

According to some embodiments, systems and methods for reshaping bone are provided. The systems may include an implant body, an actuator coupled to the implant body, a sensor configured to detect a parameter indicative of a biological condition, a transceiver, and a controller. The transceiver may be configured to transmit data associated with the parameter to an external remote control and receive instructions from the external remote control. Finally, the controller is configured to move the actuator in response to the instructions from the external remote control, wherein the actuator adjusts the implant body. The methods may include measuring a parameter indicative of a biological condition; transmitting data associated with the parameter from the implantable device to an external remote control; transmitting instructions from the external remote control to the implantable device; and actuating the bone growth device in response to the instructions from the external remote control.
