Smart device for non-invasive skeletal adjustment

Номер: US20120101527A1
Автор: Robert A. Connor
Принадлежит: Orthonex LLC

This invention is an implantable device and system that allows post-operative, non-invasive adjustment of members of the skeletal system. It includes extension-resisting members and a compression-resisting member that connect members of the skeletal system. Post-operative, non-invasive adjustment of the tensions, lengths, widths, and/or torsions of the extension-resisting members changes the relative movement, position, or both movement and position of members of the skeletal system. The compression-resisting member may act as a fulcrum. This invention can help to pioneer the evolution of “smart” orthopedic devices that adjust skeletal biodynamics to address changing clinical needs and changes in patient activity over time. Some promising applications include: dynamic stabilization of the spine; correction of scoliosis; and bone elongation.

The fixation instrument includes a tension assembly that is configured to secure a free end of the bone fixation member to the fixation instrument. The tension assembly is further configured to pull the free end so as to increase tension in the loop while the tension in the loop is less than a select tension. The tension assembly is unable to further increase tension in the bone fixation member once the tension in the bone fixation member has reached the select tension. The fixation instrument further includes a cutter assembly that is configured to cut the free end of the bone fixation member so as to separate the free end from the loop.

Percutaneous Technique and Implant For Expanding The Spinal Canal

Номер: US20120215312A1
Автор: D. Greg Anderson
Принадлежит: ISD Innovative Surgical Designs Inc

Expanding a spinal canal by drilling a cylindrical passage in each pedicle of a vertebra, making a circumferential pedicle cut (osteotomy) through each pedicle from within the passage, separating each pedicle cut by inserting an implant into the passage to distract the pedicle cut (i.e., lengthen the pedicle) to expand the spinal canal, and securing each pedicle cut, allowing the vertebra to heal with the spinal canal expanded. The implant can include an outer sleeve, an inner bolt, and expandable flanges. The outer sleeve includes an upper and a lower portion, with the expandable flanges therein. Rotation of the inner bolt causes the upper and lower portions of the outer sleeve to separate, causing the pedicle cut to widen and the expandable flanges to radially extend into and stabilize the widened pedicle cut for expansion of the spinal canal.

Spine Stabilization

Номер: US20120265203A1
Автор: Brian GARVEY, Christopher Angelucci, Colm McLaughlin, James Himmelberger, Michael Black, Robert W. Trout
Принадлежит: Globus Medical Inc

A bone stabilizing plate includes two plate portions, each affixable to bones of a patient, the plate portions telescoping together with mating rails and grooves. A limiter associated with one of the plate portions sliding engages one a catch associated with the other of the plate portions, when the plate portions are telescoped together, and resists stops telescoping when the plate portions are telescoped a predetermined distance apart. Once the limiter and catch are engaged, the plate portions enable imposition of a minimum compressive force between bones connected to the plates. The limiter is resiliently positioned to deflect into a relief formed in its respective plate portion. A groove positioned proximate the catch enables free telescoping motion limited by the engagement of the catch and limiter, whereby the minimum compressive force between bones is maintained, and Wolfe's Law may apply.

Juxta-articular stabilisation system

Номер: US20120290016A1
Автор: Deepak Kumar
Принадлежит: Individual

The juxta-articular stabilisation system constitutes of a plate with integral pin and tail part, a plate specific jig, a plate and jig specific drill sleeve, a plate positioner, a slotted head screw, a pin bender, screws and pins. This system can be used for fixation of most types of fractures involving the juxta-articular radius. The plate has a most juxta-articular row of screw holes in individually bendable and detachable extensions especially designed for very distal fractures or the volar lip fractures. The plate and jig assembly have plate positioning apertures in its juxta-articular part to allow adjustment in position of plate in longitudinal, transverse and oblique directions after temporary fixation to the juxta-articular fragment with a pin prior to fixation to diaphyseal fragment. This allows a very precise placement of the plate in the most desirable position. The drill guiding jig can be assembled to the plate prior to surgery thus reducing surgical step and time. The specific orientation of the screws holes in the diaphyseal part of the plate orientates the screws such that when tendons apply forces across the fracture, the plate is wedged between screw and the bone rather than pushed away from the bone. Therefore, more aggressive physical therapy can be commenced earlier and plates with fewer screws in the proximal part can be used without compromising the strength of the fixation. The plate also has bendable and dividable pin part and tail parts on either ends that allows the plate to be used with a chuck or power tool as a pin or drill bit and also have longer purchase into the bone with minimal soft tissue exposure.
