Developed in conjunction with J. 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. In most cases of adult forearm fractures, both bones are broken. Operative medtroni 1 Anesthesia General intravenous anesthesia GIVA is recommended longirude in the thoracic spine, but not necessarily in the lumbar spine.

While some fractures are very serious injuries that require emergency treatment, other fractures can.

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

Suspected or documented metal allergy or intolerance. Three-dimensional fluoroscopy-guided percutaneous thoracolumbar pedicle screw placement: Successful percutaneous placement of longitide screws requires surgical skill and experience because of lack of anatomic surface landmarks.

Postoperative recovery during the up to 2year follow-up was rapid for all patients. Universal system Modular packaging maximizes screw options Low-profile design More ,ongitude. Tissue or nerve damage caused by improper positioning and placement of implants or instruments. Imaging review of percutaneous pelvic fracture medrronic.


Spine Radius Surgical Technique Precision Zone of locking security Non-threaded locking mechanism Simple, low torque closure Low profile, low volume multi-angle screw Introduction Minimally invasive systems. The ports needed to be removed in a blind procedure to pass the rod between the screws.

Remove all packaging materials prior to sterilization. For the Sextant system, the screw extenders are lined up, and a rod measuring device is used to measure the appropriate rod length Fig.


Dural tears, pseudomeningocele, fistula, persistent CSF leakage, meningitis. Loss of or increase in spinal mobility or function. If the line is visible, the Rod is through the Extender Figure If the rods are cut to length, they should be cut in such a way as to create a flat, non-sharp surface perpendicular to the midline of the rod.

Internal fixation for a two-level fusion can be provided by placing screws in the end vertebrae, skipping the intervening vertebra. This was because the first and second generation of the Sextant system allows only some distraction and compression that may be ineffective in step reduction.

Open surgery always remains a solution if there is a problem. In the Sextant system, the screw extenders are aligned and a rod measuring device is used to measure the appropriate rod length.

Low Back Surgical Technique. Follow up ranged between 6 months and 48 months.

Although two adjacent pedicles can be accessed through a single larger incision, we do not recommend larger incisions.

Potential complications of percutaneous screw placement with or without fusion were recorded. We had to repeat all steps of screw introduction from the beginning.


To attain exposure, use a dissection or preferably a dilation technique to visualize the head of each Screw Figure Potential complications Regarding the need for fusion, biomechanically the survival of the implant is questionable.

Guidewire, Screw Extender placement and Rod passage are shown on one side only for clarity. The deficiencies of such pacemakers were made painfully obvious following a power outage over Halloween in which affected large sections of Minnesota and western Wisconsin. Several recent approaches to minimally invasive posterior fusion with internal longiude have been described.

If buttons are held until unreduce past EJ, the Outer Extender will pull off entirely. If needed, use longirude Rod Bender to bend the Rod according to patient anatomy Figure 38c.

In addition to the steps detailed in the following pages, a graft must be used when implanting the construct. The Rod may then be passed in a lordotic manner through the first two Extenders with the handle on its side.

In later cases, we cannulated all pedicles on each side, longituce both pedicles per vertebra simultaneously under AP projection. Figure 30a Figure 30c Figure 30b If it is difficult to rotate the hex, check the Screw alignment to ensure the Screw is not slightly rotated.
