Cervical Pedicle Screw Placement Using Medial Funnel Technique
OBJECTIVE Cervical pedicle screw (CPS) placement is very challenging due to high risk of neurovascular complications. We devised a new technique (medial funnel technique) to improve the accuracy and feasibility of CPS placement. METHODS We reviewed 28 consecutive patients undergoing CPS instrumentation using the medial funnel technique. Their mean age was 51.4 years (range, 30-81 years). Preo...
متن کاملPlacement of pedicle screws in the human cadaveric cervical spine: comparative accuracy of three techniques.
STUDY DESIGN This investigation was conducted in two parts. In the first part, a morphometric analysis of critical cervical pedicle dimensions were measured to create guidelines for cervical pedicle screw fixation based on posterior cervical topography. In the second part of the study, a human cadaver model was used to assess the accuracy and safety of transpedicular screw placement in the suba...
متن کاملAccuracy of fluoroscopy versus computer-assisted navigation for the placement of anterior cervical pedicle screws.
STUDY DESIGN Randomized laboratory cadaver study. OBJECTIVE The objective of this study was to determine the accuracy of anterior transpedicular screw placement in the cervical spine using conventional fluoroscopy versus computer-assisted navigation. SUMMARY OF BACKGROUND DATA Traditionally, global cervical instability has required anterior and posterior fixation due to the superior biomech...

متن کاملThoracic 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...
