A surgical instrument system comprises surgical instruments for use with an implantable interspinous device having at least one pair of wings for securing the implantable device to a spinous process. The instrument system may include a surgical instrument for expanding or spreading the pair of wings to accommodate the spinous process. Further, a surgical instrument may be provided for crimping or compressing the pair of wings against the spinous process for secure attachment of the device to a vertebra. The surgical instruments may be configured similar to pliers and apply force to the pair of wings within a predetermined range so as to avoid damage, weakening or breakage of the pair of wings. The surgical instrument system may also include interspinous devices of differing sizes.

Instrument system for use with an interspinous implant

A method for measuring an X-ray image of an area undergoing medical examination that has at least one object. A 3D model is provided of the area undergoing examination that includes a virtual 3D object to be assigned to the object to be measured, a digitally reconstructed X-ray picture is computed based on the 3D model and under the assumption of a virtual projection direction, the X-ray image is compared with the digitally reconstructed X-ray picture, the virtual projection direction is changed relative to the virtual 3D object. The steps of comparing and changing are repeated until a virtual projection direction with maximum correlation between the X-ray image and the digitally reconstructed X-ray picture is found. An object plane is determined that is to be assigned to the virtual 3D object. A corrected projection direction is defined and the X-ray image is measured.

The present invention provides interspinous vertebral and lumbosacral stabilization devices, and methods of using these devices for treating spinal instability conditions. The invention includes interspinous vertebral stabilization devices adapted for placement between the spinous processes of two or more adjacent vertebrae. The invention also includes lumbar stabilization devices adapted to be placed between a lumbar vertebra and an adjacent vertebra, including the first sacral vertebra (S1), to stabilize the lumbosacral region of a patient, and method for using such devices.

Interspinous vertebral stabilization devices

The invention relates to a uniplanar bone anchoring element () comprising an anchoring screw () with a bone thread () and a screw head (), which is flattened on at least one side (); a receiving element () that has a through-bore which tapers in a lower region () and in which the anchoring screw () can be received; and two limbs () which extend upwards and which comprise a threaded profile () in an upper region, said threaded profile being designed for screwing on a securing screw. The receiving element () has an inner groove () which partly runs at least in the circumferential direction in the seat region of the anchoring screw head (). The bone anchoring element also comprises a bearing element () for inserting into the inner groove () of the receiving element (). The bearing element () is partly flattened on at least one side (), and the groove and the bearing element are designed in a complementary manner such that the bearing element is positioned in the groove in a specified position.

Uniplanar bone anchoring element

Implantable devices are provided for stabilizing adjacent vertebrae and the lumbosacral region of a patient. The devices can comprise an interspinous flexible spacer body having a substantially U-shape comprising a superior section, inferior section, and a midsection extending therebetween. The superior and/or inferior sections can include a pair of lateral walls configured to engage a spinous process of a vertebra. Fixation caps can be provided for securing a spinous process of a vertebra to the flexible spacer body. To secure the flexible spacer body between the lumbar vertebra and an adjacent vertebra, an anchor assembly is provided. Also provided are methods of using the implantable devices to stabilize a patient's spine.

Interspinous vertebral and lumbosacral stabilization devices and methods of use

The invention relates to an osteosynthesis device having a bone screw (), which has a threaded shaft () and a ball head (), and having a fork head (), which has a groove () and two legs (), the ball head () being pivotably supported in the fork head (), and having a pressure piece (), which is seated on the ball head (), the pressure piece () being braced on the fork head () and having two lateral fins () extending in the axial direction () of the fork head () and away from the threaded shaft (); it is proposed that the pressure piece () is supported in the fork head () with prestressing in the axial direction () and thus in the direction toward the ball head () in that at least one of the fins () is slit transversely to the axial direction () of the fork head (), so that a slit () forms a spring tongue (), and the pressure piece () is thereby resiliently embodied and is braced via the spring tongue () on the fork head (), and that a protrusion () protrudes in the axial direction () into the slit (); and that the protrusion (), for limiting deformation or deflection of the spring tongue (), forms a stop (), acting in the axial direction (), for the spring tongue ().

Osteosynthesis device

A functionally dynamic stabilization unit and system for treatment of spinal instability are provided. Each unit, and collectively, the system, is configured to control flexion, extension and translation of the affected unstable vertebral area, thereby stabilizing the vertebral segments by restoring normal function. This is achieved by providing a unit and system that allow for lateral bending, axial compression, rotation, anterior segmental height adjustment, and posterior segmental height adjustment. The unit and system provide sufficient segmental stiffness, while also limiting, or controlling, the range of motion (i.e., sufficient stiffness in the neutral or active zone, while limiting or preventing motion outside of the active zone) to stabilize the vertebral segments. In use, the system mimics the natural movement of the normal spine. Furthermore, the system includes a rigid, fusion-promoting coupler configured for use in an adjacent level, or as a substitute for the functionally dynamic unit. The modularity of the system allows adjustment over time and easier revision surgery, and is configured for minimally-invasive, delivery or implantation.

Posterior functionally dynamic stabilization system

A method and system are provided for preparing an interspinous space to receive an implantable device. The system may comprise a cutting tool guide having a guiding surface for directing a cutting tool therethrough and a holder for positioning the cutting tool guide relative to the interspinous space. The holder may be configured to adjustably attach to at least one of a pair of spinous processes defining the interspinous space.

Spinal implant

The invention relates to a spinal implant composed of a plurality of parallel plates. The deliberate introduction of contours in the plates allows for the creation of biomechanically advantageous functions and adjustment options. The elasticity of the anchoring elements enables the disclosed implant to be adjusted to the osseous endplates, resulting in uniform force distribution and thus prevention of the risk of compaction or endplate compression fracture. The plate structure allows for the use of production methods in which hook-like undercut contours can be created, thus enabling the implant to be superbly anchored in the bone without causing damage thereto. Furthermore, the plates can be interconnected by an actuator in such a way that the height and/or the angular position can be adjusted. The vertical adjustment can vary along the length of the implant such that the segment can also be angularly adjusted.

Intervertebral medical implant

The invention relates to an implant in the form of a bone-connecting device with an implant carrier, having at least two structure carriers for stimulating bone growth, the structure carriers can move relative to one another so that, due to a loading of the implant, a relative movement of the structure carriers occurs, the structure carriers furthermore contain structure elements that are arranged so that they define a plurality of partially open intermediate spaces, wherein a volume defined by these intermediate spaces and an immediate environment is deformed by the implant load, and a strain in the intermediate spaces and its immediate environment resulting from the deformation lies in the physiological range for bone growth.
