Grab the Inner Sleeve and pull it straight out of the Extender without squeezing the Extender tips together. Reproductive system compromise, including lontitude, loss of consortium, and sexual dysfunction.

ALIF Anterior In human anatomy, referring to the front surface of the body or the position of one structure relative to another Lumbar Relating to the loins or the section of the back and sides between.

Placement of pedicle screws in the thoracic spine. Ensure that the guidewire does not advance during tapping or screw insertion. Easy loose wire movement and advancement may warrant trajectory revision, as it carries the possibility of being outside the vertebral body.

General intravenous anesthesia GIVA is recommended routinely in the thoracic spine, but not necessarily kongitude the lumbar spine. No further complications were detected during the follow-up period.

Figure 41 Figure Herniated Disk in the Lower Back. Rapid postoperative recovery, less postoperative pain, and better function means that the theoretical benefits of have been achieved. Bracing for standalone rods and screws is controversial, especially in trauma cases. The spacer portion of the device is manufactured from Polycarbonate-Urethane. Any case where the implant components selected for use would be too large or too small to achieve a successful result.

The cable is fabricated from a 7×7 filament yarn made from titanium alloy, with a cylinder rotary-swaged to the end, made from the same material. The study included 40 patients 22 females and 18 males ranging in age from 25 to 70 years mean age, Operative techniques, technical tips, and longtiude were recorded for both systems.


Figure 38c To estimate any bend for the Rod, place the Rod Inserter lateral msdtronic the patient and take a lateral fluoroscopy. Care should be taken so that the correct components are used in the spinal construct. Figure 33 Figure 32 Care should be used to avoid inadvertent Guidewire removal and unguided Screw placement.

Percutaneous Transpedicular Fixation: Technical tips and Pitfalls of Sextant and Pathfinder Systems

In the Sextant system, the screw extenders are aligned and a rod measuring device is used to measure the appropriate rod length. Care should be taken not to dislodge the guide wire while removing the Jamshidi needles, taps, and other materials.

Instruments for removing Synthes screws. Loss of or increase in spinal mobility or function. If buttons are held until unreduce past EJ, the Outer Extender will pull off entirely. However, we recommend a more lateral incision in lumbar vertebrae, which will create the right trajectory for instrumentation placement in line with long axis of the pedicle [ 11122122 ]. Break-off Set Screw accordingly. Federal law USA restricts these devices to the sale by or on the order of a physician.

Understanding your spine Disc Between each pair of vertebrae there is a disc that acts as a cushion to protect the vertebra. Cut the rods outside the operative field. Hip Knee Spine Navigation. Many percutaneous fixation systems have been introduced in spine practice.

The implants should not be scratched or otherwise damaged.


To allow the maximum chances for a successful surgical result, the patient or devices should not be exposed to mechanical vibrations or shock that may loosen the device construct. Since the system was developed for minimally invasive procedures of the lumbar spine, only pre-bent lordotic rods are currently available. The exception was an elderly female whose general condition contraindicated GIVA. The PathFinder fixation system has smaller diameter pedicular screws available for use in the thoracic pedicles.

Further, the proper selection and longitudde of the patient will greatly affect the results. Like the Muller technique, the ,ongitude procedure involves blind tunneling for the rod passage with no provision for hemostasis in the muscle.


Page 3 Surgical Technique Posterior More information. Bakken began as a graduate student in electrical engineering at the University of Minnesota before he gave up his studies to focus on Medtronic.

Place Suction Trephine down the shaft and rotate to remove blood and tissue that could be impeding the start of the Set Screw Figure Successful percutaneous placement of pedicle screws requires surgical skill and experience because of lack of anatomic surface landmarks.

Unreduce other extender by one-half turn to allow it to slide along Rod. No wound infections occurred.

Footer Facebook LinkedIn Twitter. Key elements of the instrument set are a steerable rod inserter and reduction screw extenders. The Sextant percutaneous stabilization system consists of polyaxial cannulated screws and pre-bended lordotic rods with Jamshidi needles, guide wires, cannulated tap, and special assembly connectors.

Fractures of the Thoracic and Lumbar Spine The kongitude common fractures of the spine occur in mestronic thoracic midback. The needle is then moved laterally 1cm to 2cm and inserted through the skin at the intersection of the facet and transverse process Figure 6. Detailed instructions on the use and limitations of the device should be given to the patient. I have been strongly advised to carefully read and consider this operative permit.

We recommend a more lateral incision lateral to the border of the pedicle on AP imaging for percutaneous transpedicular placement, especially in lumbar vertebrae, to create the right trajectory for placement of instrumentation.

The benefits of kongitude invasive spine surgery MIS include decreased longihude, less blood loss, shorter hospital stays and faster recovery. Designed For Maximum Adaptability. The risk of bending, loosening, or breakage of a temporary internal fixation device during postoperative rehabilitation may be increased if the patient is active, or if the patient is debilitated or demented.

All procedures were performed with the Sextant group A and PathFinder group B systems under fluoroscopic guidance.
