Method for expanding bone crest and an implant-expander for use in said method

Номер: US20120082952A1
Автор: Eduardo Anitua Aldecoa
Принадлежит: BTI Biotechnology Insttitute

Method for expanding bone crest ( 1 ) in order to receive the installation of a final dental implant ( 4 ), where the bone crest ( 1 ) is expanded using a implant-expander, in other words, a biocompatible and osteoconductive piece that has an expander function. The use of an implant-expander ( 3 ) to widen the bone crest ( 1 ) has the important effect of said implant-expander acting as a support to the bone and therefore helping to consolidate the fracture of the bone crest ( 1 ) and the formation of bone around said implant-expander. The bone generated around the implant-expander ( 3 ) is therefore of a high quality. The invention also contemplates the optional correction of the angulation of the alveolus during the widening process, so that the final dental implant ( 4 ) and the corresponding dental prosthesis are adequately oriented. It is also an object of the invention to provide a specific design for the implant-expander ( 3 ).

A rotational correction system includes an implant having first and second sections, the implant having a rotatable permanent magnet disposed in a housing of the first section, the rotatable permanent magnet mechanically connected to a nut operatively coupled to the second section. A keyed portion is interposed between the nut and one or more non-linear grooves disposed on an inner surface of the housing. An external adjustment device having at least one rotatable magnet configured to rotate the rotatable permanent magnet of the implant is part of the system. Rotation of the rotatable permanent magnet of the implant in a first direction effectuates a clockwise change in the rotational orientation of the first section relative to the second section and rotation of the rotatable permanent magnet of the implant in a second direction effectuates a counter-clockwise change in the rotational orientation of the first section relative to the second section.

Intramedullary nail having self-retaining compression slot

Номер: US20120209268A1
Автор: Tom Overes
Принадлежит: Synthes USA LLC

An intramedullary nail has a scalloped compression slot so as to define a plurality of pockets and intersections between the pockets that are narrower than the pockets. Accordingly, a compression member can be inserted into a bone segment of a fractured bone and into the slot. The compression member can be wider than the intersections. A compression actuator can apply a force against the compression member that causes the compression member to translate across the intersections from pocket-to-pocket until the fracture has been approximated. Because the compression member is wider than the intersections, the compression slot retains the compression member and prevents distraction of the fracture.

Принадлежит: Howmedica Osteonics Corp

Disclosed herein are systems and methods for identifying the proper implant for use in an arthroplasty procedure and preparing a bone surface for the placement of such implant. In one embodiment, a centering guide system includes a cannulated post and a translucent surface trial where the cannulated post includes a slit defining legs that flex to engage the post when inserted in a hole of the surface trial. The system is used to confirm a suitable implant size and place a pilot wire in preparation for implant placement. The cannulated post and the translucent surface trial provide comprehensive visibility of the glenoid surface. When inserted into the surface trial, an extension of the cannulated post beyond an articulating surface of the surface trial is minimal or nonexistent. In this way, the congruence of a reamed glenoid surface can be evaluated prior to implantation of the implant.

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.
