An implantable medical device for implantation in a hip joint of a human patient is provided. The medical device comprises: at least one artificial hip joint surface adapted to replace at least the surface of at least one of the caput femur and acetabulum. At least one artificial hip joint surface comprises: a positioning hole with at least one opening in said at least one artificial hip joint surface. The hole is adapted to be placed and dimensioned such that the medical device is adapted to be fitted using a positioning shaft and at least partly surround the shaft, for positioning the at least one artificial hip joint surface in a desired position in the hip joint. The hole is adapted to be fitted using the positioning shaft, when the shaft is stabilized and placed in at least one of the femoral bone and the pelvic bone for positioning said medical device inside the hip 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.

A bone fixation device for treatment of a bone fracture includes a fixation screw defining a transverse opening, a fixation arm configured for inserting the fixation screw through a bone fracture, a set screw, and an aiming arm configured for inserting the set screw into the transverse opening and engagement with the fixation screw. The set screw stabilizes the fixation screw.

Intramedullary nails, systems, and methods. The intramedullary nail may include a generally elongate body extending from a first, distal end to a second, proximal end. The distal end may include one or more openings configured to receive one or more bone anchors that extend transversely through the distal end intramedullary nail, and thereby configured to secure the distal end of the nail. The proximal end may also include one or more openings configured to receive one or more bone anchors that extend transversely through the proximal end of the intramedullary nail, and thereby configured to secure the proximal end of the nail. In some embodiments, the proximal end may further include a cross-locking feature, which includes a second bone anchor that interlocks with a first bone anchor, for example, for enhanced bone purchase and bony fixation.

Devices, systems, and methods for locking a drill guide into a polyaxial hole while maintaining the form and function of the polyaxial hole are provided herein. In some embodiments, the drill guide includes a hollow outer body extending from a proximal end to a distal end and having a slot disposed proximate the proximate end, wherein the distal end is configured as a reverse collet having a plurality of prongs; an inner body having a central channel extending therethrough; and a lever coupled to the inner body through the slot, wherein the slot is shaped such that rotation of the lever results in motion along a central axis of the drill guide, and wherein a distal end of the inner body is configured to prevent radially inward deflection of the plurality of prongs when the inner body is in a lowermost position.

An implant and method for fixation of long bones. The implant provides rotational, longitudinal, and bending stability. The implant comprises one or more elongated members that span the intramedullary cavity of a long bone, a distal tip that expands radially relative to the long axis of the implant, and a locking mechanism at the proximal end of the implant.

Implant delivery systems for delivering sheet-like implants include a delivery shaft, an implant expander, a sheath, and a sheet-like implant. In some embodiments, the delivery shaft has a proximal end and a distal end. The implant expander is mounted to the distal end of the delivery shaft. The implant expander includes a central portion and a plurality of leg portions radiating from the central portion. The implant expander is evertable between an unstressed configuration in which a distal surface of the implant expander defines a concave surface, and a first compact configuration in which the distal surface of the implant expander defines a convex surface. The implant expander has a first lateral extent when the implant expander is free to assume the unstressed configuration. The sheath defines a lumen having a lumen diameter. At least a portion of the delivery shaft is slidably disposed in the lumen. The lumen diameter is smaller than the first lateral extent of the implant expander so that the sheath holds the implant expander in the first compact configuration when slidably disposed therein. The sheet-like implant overlays at least a portion of the distal surface of the implant expander with portions of the sheet-like implant extending between the leg portions of the implant expander and the sheath. Methods of treating a rotator cuff of a shoulder are also disclosed.

A hip/shoulder prosthesis includes: a head component; a metaphyseal component; a diaphyseal nail, and a locking device. The head component includes: a front face and rear face; with a bore, and first and second shaped recesses in the rear face. The metaphyseal component includes: a central transverse aperture at an angle to the metaphyseal component's axis; a first end configured for threaded engagement within the bore of the head component; and a longitudinal hole that begins at the second end, transects the transverse aperture and reaches the first end, to receive the locking device. The diaphyseal nail is inserted in the femoral or humeral canal, and includes: fastening apertures that receive corresponding screws for fastening the diaphyseal nail to the femur or humerus; a portion configured to be received within, and engage, the transverse aperture of the metaphyseal component, and a transverse hole configured to receive the locking device.

An expandable implant system is configured to increase the height of a target bone, for instance that has been subjected to a compression fracture. The expandable implant system includes an implant assembly that can be inserted into the target bone, and subsequently expanded so as to increase the height of the target bone. The expandable implant system further includes an and insertion assembly that is configured to create an insertion channel into the target bone, such that the implant assembly can be inserted in a collapsed configuration into the target bone along the insertion channel, and subsequently expanded.

The present invention relates to an implant system that comprises an implant, a handle configured to removably receive the implant, and, in some embodiments, a spacer tool configured to be mounted on the implant. In further embodiments, a k-wire is employed to guide the implant to a desired location. The handle has a hole for receiving a first portion of the implant. Using the handle to implant the implant, along with an associated spacer, provides a quick and convenient method for implanting the implant as described herein and in the associated drawings.
