Incidence of Misplaced Pedicle Screw in Free Hand Technique in Spine Fixation Patients

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...

Pedicle screw fixation in the spine.

In August 1993, in the USA, an FDA advisory committee of experts reviewed the scientific data on pedicle screws and decided that not enough was known about the shortterm problems or the long-term safety and effectiveness of these devices to allow their use to be approved. Manufacturers were therefore forbidden to promote the use of screws in the spine, and patients were warned that pedicle scre...

Pedicle Screw Fixation in Fracture of Thoraco-lumbar Spine

Free hand technique of cervical lateral mass screw fixation

STUDY DESIGN We introduce a simple free hand technique with great ease of application, without angles, measures or degrees, and without any fluoroscopic guidance. It is a safe and reproducible technique. We present our preliminary experience with the use this technique, with inimitable simplicity. PURPOSE The primary aim of the procedure was to achieve adequate screw trajectory in an apparent...

efficacy of pedicle screw fixation in unstable upper and middle thoracic spine fractures

conclusions application of pedicular screw in unstable upper and middle thoracic spine fractures is an effective method that can correct kyphotic deformity and anterolisthesis and improve neurologic deficit. background treatment of unstable upper and middle thoracic spine fractures remains controversial. there is no consensus regarding optimal treatment. objectives in this study, we evaluated t...
