Abstract: A spiral growth tether system may be securable to a bone having a growth plate that separates a first portion of the bone from a second portion of the bone. The spiral growth tether system may include a tether including a first end configured to be secured to the first portion, a second end configured to be secured to the second portion, and a central portion between the first end and the second end. The first end and the second end may be configured to separate at the central portion in response to the first end being urged away from the second end as a result of growth of the bone urging the first portion away from the second portion.

Abstract: A system for external rotational deformity correction of an intact bone may include: a first frame member and a second frame member rotatably coupled therewith, a first bone fixation member coupled to the first frame member and to a distal segment of the intact bone, a second bone fixation member coupled to the second frame member and to a proximal segment of the intact bone at a first angle, an automated control mechanism coupled to the first and second frame members, and a power source for the automated control mechanism. The automated control mechanism may: receive power from the power source, rotate the first frame member to a desired relative rotational position, and position the first bone fixation member at a desired second angle to exert torsional force on the intact bone and externally reduce rotational deformity of the intact bone.

Abstract: A tether assembly may be attached to a bone to correct a rotational deformity. The bone may have a growth plate that separates a first section of the bone from a second section of the bone. The tether assembly may have a tether member with a first end, a second end, and a central portion extending between the first end and the second end. The first end may have a closed outer wall that defines and fully bounds a first aperture. The second end may have an open outer wall that defines and partially bounds a second aperture. The open outer wall may define a slot in communication with the second aperture. The first and second ends may be securable to the first and second sections of the bone via coupling members inserted through the first and second apertures and anchored in the first and second sections, respectively.

Abstract: An apparatus and method for external anteversion correction of an intact bone may include a first arcuate segment, a second arcuate segment rotatably coupled to the first arcuate segment, a first pin extending from the first arcuate segment to a proximal segment of the intact bone, a second pin extending from the second arcuate segment to a distal segment of the intact bone, and a control mechanism attached to the first and second arcuate segments. The control mechanism may rotate the first arcuate segment relative to the second arcuate segment to exert torsional force on the intact bone between the proximal and distal segments of the intact bone, thereby externally reducing anteversion of the intact bone.

Abstract: A cap for a c-arm medical imaging device with an image intensifier comprises a plate sized and shaped to cover an exterior facing surface of the image intensifier. The plate is transparent to x-rays and has a planar center with a planar outer surface and a planar inner surface to face the image intensifier. A retainer is carried by the plate to retain the plate on the image intensifier.

Abstract: A method for correcting an angular deformity in a bone includes positioning a link across a physis of the bone, the link having a first portion with a first opening, a second portion with a second opening, and a central portion extending between the first portion and the second portion, the central portion being more flexible than the first portion or the second portion. A first bone engager and second bone engager are advanced through the first opening and the second opening, respectively, and into the bone on opposing sides of the physis. The physis is allowed to generate more physeal tissue on a side of the bone opposite the link so as to reduce the angular deformity.

Abstract: A system is provided for stabilizing bone. The system includes a fixing block, a pin having a far end which is adapted to be fixed directly into bone and a near end which enters the fixing block, and a frame on which the fixing block is fixable. The pin enters the fixing block in a non-orthogonal manner in order to permit the pin to enter the bone with an orientation which is non-orthogonal to the bone's surface, thereby permitting the pin to engage more of the bone.

Abstract: A bone alignment implant includes a first bone fastener with a first bone engager that is adapted for fixation into the metaphyseal bone and a second bone fastener with a second bone engager that is adapted for fixation into the diaphyseal bone. A link connecting the two fasteners spans across the physis. Alternatively, the bone alignment implant is adapted for fixation into the diaphyseal sections of two adjoining vertebral bodies. These implants act as a flexible tethers between the metaphyseal and the diaphyseal sections of bone during bone growth. These implants are designed to adjust and deform during the bone realignment process. When placed on the convex side of the deformity, the implant allows the bone on the concave side of the deformity to grow. During the growth process the bone is then realigned. A similar procedure is used to correct torsional deformities.

Abstract: A method for correcting an angular deformity in a bone includes inserting a guide wire within a physis of a bone having an angular deformity, the physis extending between a first side the bone on which the guide wire is inserted and an opposing second side of the bone. The guide wire is used to guide a link to the physis. The link is then secured to the first side of the bone so that the link spans across the physis and restricts the growth of the physeal tissue of the physis on the first side of the bone. The physis is then allowed to generate more physeal tissue on the second side of the bone than on the first side of the bone so that the angular deformity of the bone is reduced.

A link connecting the two fasteners spans across the physis. These implants act as a flexible tethers between the epiphyseal and the metaphyseal sections of bone during bone growth.

When placed on the convex side of the deformity, the implant allows the bone on the concave side of the deformity to grow. During the growth process the bone is then realigned.
