System and method for insertion of flexible spinal stabilization element

Номер: US20120035664A1

Автор: Emmanuel Zylber, Michael Filippi, Nimrod Meier, Thomas Egli

Принадлежит: ZIMMER GMBH

Insertion of a spinal stabilization element into a patient generally includes positioning a cord within a sheath and inserting the sheath and cord through the patient's body along a path generally toward an anchor member. An advancement member may be mounted on the leading end of the cord to further facilitate this insertion. The sheath is then retracted to expose a first portion of the cord within the patient's body, and the first portion of the cord is moved into a desired position relative to the anchor member. After advancing a spacer over the sheath and cord, the sheath is retracted to expose a second portion of the cord. The second portion of the cord is then moved into a desired position relative to another anchor member such that the spacer is positioned between the two anchor members.

A modular dynamic pedicle screw system including anchoring device having a threaded shank for anchoring within a vertebra, an intermediate element and a head portion configured to receive and secure a rigid or non-rigid stabilization rod. The threaded shank, the intermediate element and the head portion of the anchoring device are cannulated to permit percutaneous implantation of the device. The intermediate portion is designed to be removable from the threaded shank portion subsequent to implantation of the anchoring device to enable substitution of another intermediate element having different dynamic characteristics. The dynamic stabilization system includes an adjustable torque limiting device that is interchangeable between a tap device and a screw driver. The torque device provides information relative to the patient's bone quality inter-operatively in order to determine the appropriate modulus of elasticity for the dynamic pedicle screw.

Percutaneous compression and distraction system

Номер: US20120191137A1

Автор: Jeffery Arnett, Joshua A. Butters

Принадлежит: Stryker Spine SAS

A compression and distraction shaft assembly applies compression and distraction to bones including vertebrae. Shaft A assembly and shaft B assembly are attached together via a polyaxial fulcrum. The polyaxial fulcrum allows all rotational degrees of freedom between shaft A assembly and shaft B assembly. Such fulcrum, during compression and distraction, does not impart ancillary stresses or motion to vertebrae. An hourglass-shaped bore for engaging pliers is formed in approximately middle of both the shaft A assembly and the shaft B assembly. Distraction pliers having cylindrical tips are used to apply distraction to vertebrae. Once handles are pressed to impart an appropriate amount of distraction to the vertebrae, they are locked in this position. Compression pliers having cylindrical tips are used to apply compression to vertebrae. Once handles are pressed to impart an appropriate amount of compression to the vertebrae, they are locked in this position.

Another exemplary assembly can include a plate that is seated between the receiver member and the rod and accommodates one or more auxiliary bone anchors that augment the fixation of the assembly's primary bone anchor. Another exemplary assembly can include a hook that extends out from the receiver member to hook onto an anatomical structure or another implant to augment the fixation of the assembly's primary bone anchor. Surgical methods using the bone anchor assemblies described herein are also disclosed. 1. A bone anchor assembly , comprising:a bone anchor;a receiver member coupled to a proximal end of the bone anchor and defining a recess configured to receive a rod;a closure mechanism threadably mated to the receiver member;a wing having a proximal portion disposed proximal to the receiver member, a distal portion that defines a bone anchor opening, and a spanning portion that connects the proximal and distal portions; anda nut configured to threadably engage the closure mechanism to secure the proximal portion of the wing to the proximal end of the receiver member.2. The assembly of claim 1 , wherein the closure mechanism comprises a threaded post and wherein the wing includes an opening through which at least a portion of the threaded post is disposed.3.

REVISABLE ORTHOPEDIC ANCHOR AND METHODS OF USE

Номер: US20160008033A1

Автор: Grinberg Alexander, Hawkins John Riley, Michielli Michael

Принадлежит:

A revisable orthopedic anchor and method of use for removably securing an anchor in bone, such as compromised or degenerated bone, is described herein. In one embodiment, the anchor makes use of dual probes and vector divergence of the distal tips of the probes to achieve superior bone purchase and pull-out resistance. In such an embodiment, the probes can be inserted one at a time into a hole formed in, for example, the pedicle bone. After the probes are inserted and joined at the proximal end, they have a greater pull-out resistance than a threaded anchor. Removing the anchor involves separating the proximal heads and reversing the implantation process. As a result of the unique bone anchor design disclosed herein, the devices and methods of the present invention allow for less complicated implantation and removal of orthopedic anchors, all while providing enhanced bone purchase when implanted in a patient. 121.-. (canceled)22. An intervertebral implant , comprising:an implant body having opposed bone-engaging surfaces and at least one sidewall extending between the bone-engaging surfaces, wherein the implant body includes at least at least one lumen formed therein that extends from one of the opposed bone-engaging surfaces to the at least one sidewall;at least one bone anchor that includes a first probe component and a second probe component, wherein each of the first and second probe components are configured to be inserted into the at least one lumen from the at least one sidewall such that a distal end of each probe component protrudes from one of the opposed bone-engaging surfaces; anda set screw configured to be received within a threaded lumen formed in the at least one sidewall such that the set screw, in combination with the sidewalls of the at least one lumen, retains proximal heads of the first and second probe components of the at least one bone anchor in a fixed relationship with each other.23. The implant of claim 22 , wherein the implant body ...

CONNECTION ASSEMBLY

Номер: US20160008037A1

Автор: Harper Michael

Принадлежит:

An orthopedic connection assembly is described that comprises a housing member for receiving an implant that is operably connected to a receiving member for receiving an anchor member. The connection assembly is configured to have a locking mechanism that secures and fixes the relative orientation between the implant and the anchor member. The connection assembly can comprise a plate member receivable within the housing member. When a securing member such as a set screw is introduced downwardly into the housing member to secure the implant, the securing member applies a lateral force to the plate member, which presses against an interference member within the receiving member. The interference member presses against the anchor member, such that the anchor member is fixed in a position relative to the implant. 1. A method for stabilizing a spine comprising the steps of: a housing member including a first aperture for receiving a securing member and a second aperture for receiving a spinal implant;', 'a plate member insertable into the housing member through a third aperture;', 'an interference member capable of engagement by the plate member;', 'a receiving member for receiving the interference member therein, the receiving member including a receiving aperture for receiving an anchor member therethrough; and', 'a cap member receivable over the receiving member and mateable with the housing member,', 'wherein the assembly is configured to allow for a number of variable angles between the spinal implant and the anchor member,, 'providing an orthopedic connection assembly comprisingsecuring the spinal implant and the anchor member2.
