Abstract: System, including methods, apparatus, and kits, for fixing bones with bone plates having movable locking elements.

Abstract: System, including methods, apparatus, and kits, for replacement of at least one surface region of a distal radioulnar joint using at least one prosthesis. In some embodiments, the system may provide restoration of normal, unconstrained biomechanics of the joint, which may preserve rotation and translation and ensure durability of the joint.

Abstract: System, including methods, apparatus, and kits, for bone fixation using overlapping bone plates each including a plurality of notches arranged along the bone plate to provide interchangeable overlap locations.

Abstract: A system and a method for bone fixation are provided. A bone plate may be secured to at least one bone. A monolithic region of the bone plate may be bent to a bent configuration. A strut may be connected to the bone plate. In some embodiments, the strut may be connected at spaced positions of the bone plate that opposingly flank the monolithic region, such that the bent configuration is stabilized.

Abstract: System, including methods, apparatus, kits, and components, for installation of a bone plate using an insertion tool attached to a bone plate and providing a blade for lifting soft tissue off bone in front of the bone plate as the insertion tool is advanced along a surface of the bone.

Abstract: System, including methods, apparatus, and kits, for expanded bone fixation with bone plates. A bone plate and an extension plate may be provided. The bone plate may be secured to a proximal portion of a humerus and overlapping the greater tuberosity of the humerus using fasteners received in openings defined by the bone plate. The extension plate may be attached to the bone plate and the humerus using (a) a fastener disposed in an aperture defined by the first end region and in threaded engagement with the bone plate and (b) a fastener received in an aperture defined by the second end region and extending into the humerus. The attached extension plate may extend from a position over the greater tuberosity to a position over the lesser tuberosity of the humerus such that the intermediate region is disposed over a biceps tendon.

Abstract: System, includes devices, methods, and kits, for fixing bone and/or repairing connective tissue associated with bone using a fastener constructed as a bone nail that includes at least one helical ridge having a large pitch. The large pitch permits the nail to be driven into bone by application of axial force to the nail, to secure the nail in the bone. In some embodiments, the bone nail may have a variable pitch that decreases toward the trailing end of the nail.

Abstract: A method of fusing a joint between two bones, comprising boring a hole through one of the bones across the joint therebetween and into the other bone, placing the leading end of a screw into the hole, where the screw has a threaded region having a pitch that is larger toward a leading end of the screw and smaller toward a trailing end of the screw, and driving the screw into the bone until the threaded region spans the joint.

Abstract: System, including methods, apparatus, and kits, for connecting bones and/or bone portions using a bone connector with a pivotable joint.

Abstract: Method and apparatus for replacing part of a bone with a prosthesis. The prosthesis may comprise a head configured to replace an end portion of a first bone and to articulate with an adjacent second bone. The prosthesis also may comprise a stem configured to be disposed in a bore formed in a medullary canal of the first bone. The stem may define a longitudinal axis. The head and stem may include coupling structure that permits the head to be mounted onto the stem by sliding the head into engagement with the stem in a direction transverse to the longitudinal axis of the stem.

Abstract: System, including methods, apparatus, and kits, for bone fixation with a bone plate attached to a fastener assembly including a first fastener disposed in threaded engagement with the bone plate and a second fastener disposed in threaded engagement with the first fastener.

Abstract: System, including methods, apparatus and components thereof, and kits, for connecting to bone using an anchor element configured to be anchored in bone and having a selectively bendable hinge region. In some embodiments, the system may connect the anchor element to connective tissue, a bridge member, and/or to another anchor element by bending the hinge region while the anchor element is disposed in bone, thereby connecting bone to the connective tissue or bridge member, and/or connecting bone members.

Abstract: Systems, including methods, apparatus, and kits, for fixing bones with bone plates having hybrid apertures.

Abstract: System, including methods, apparatus, and kits, for connecting bones and/or bone portions using a bone connector with a pivotable ball and socket joint.

Abstract: Systems, including apparatus, methods, and kits, for reaming bones with bone reamers.

Abstract: A system and method for installing a shoulder prosthesis. The method includes removing the original humeral head and shaping the proximal end of the humerus with one or more implements to prepare the humerus to receive the shoulder prosthesis.

Abstract: System, including methods and apparatus, for treating orthopedic conditions using a rod member structured for placement in a medullary canal of a bone and including at least one locking aperture with an internal thread structure. In some embodiments, the internal thread structure may include two or more thread leads disposed adjacent the same end of the locking aperture, two or more interspersed internal threads, and/or a thread depth substantially less than that of a corresponding threaded fastener for the locking aperture.

Abstract: Bone plates having an adjustable joint, and methods of using the bone plates to fix bones.

Abstract: Device and method for bone fixation. The device may comprise a bone plate including a plate body and a locking element. The plate body may define a plurality of openings configured to receive fasteners that secure the plate body to bone. The plurality of openings may include an elongate opening. The locking element, in turn, may define a through-hole disposed under the elongate opening for placement closer to bone than the elongate opening. The locking element may be configured to be disposed in threaded engagement with a fastener received by the locking element at the through-hole from the elongate opening. The locking element may be connected slidably to the plate body, in the absence of the fastener, to permit movement of the through-hole along the elongate opening.

Abstract: System, including method and apparatus, for applying traction to a patient's limb using constant-force springs. The constant-force springs may include one or more main springs that apply a base tractive force and at least one supplementary spring that can apply a supplementary tractive force to the limb. The at least one supplementary spring may be changeable reversibly between uncoupled and coupled configurations while the base tractive force is applied continuously to the limb and without repositioning the limb, thereby providing discrete adjustment of traction force while the limb remains in traction.
