Free hand technique lumbar spine pedicle screw placement in Indian population

Thoracic pedicle screw placement: free-hand technique.

Thoracic pedicle screws provide a number of advantages over other methods of spinal fixation in treating a variety of conditions including: better pull-out strength and greater control in the sagittal, coronal and rotational planes due to increased stability to axial, bending and rotational forces by three-column fixation, fewer vertebral motion segments arthrodesed, no or lessened need for pos...

A new free-hand pedicle screw placement technique with reference to the supraspinal ligament

We sought to compare the safety and accuracy of a new free-hand pedicle screw placement technique to that of the conventional technique. One hundred fifty-three consecutive adult patients with simple fracture in the thoracic or/and lumbar spine were alternately assigned to either the new free-hand or the conventional group. In the new free-hand technique group, preoperative computerized tomogra...

First experience with laser guided percutaneous pedicle screw placement in the lumbar spine

Since many years surgeons are trying to optimize pedicle screw placement in spine surgeries to reduce severe complications. Intraoperative image guidance could improve the accuracy in pedicle screw placement (Tain 2011). However no significant reduction of complications could be seen (Verma 2010). With the implementation of robotic 3D flat-panel detectors in hybrid operating rooms a new form of...

Pedicle Screw Fixation in Fracture of Thoraco-lumbar Spine

Free Hand Pedicle Screw Placement in the Thoracic Spine without Any Radiographic Guidance : Technical Note, a Cadaveric Study

Thoracic pedicle screw fixation techniques are still controversial for thoracic deformities because of possible complications including neurologic deficit. Methods to aid the surgeon in appropriate screw placement have included the use of intraoperative fluoroscopy and/or radiography as well as image-guided techniques. We describe our technique for free hand pedicle screw placement in the thora...
