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 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...
متن کاملCervical Pedicle Screw Insertion Using the Technique with Direct Exposure of the Pedicle by Laminoforaminotomy
OBJECTIVE To present the accuracy and safety of cervical pedicle screw insertion using the technique with direct exposure of the pedicle by laminoforaminotomy. METHODS We retrospectively reviewed 12 consecutive patients. A total of 104 subaxial cervical pedicle screws in 12 patients had been inserted. We also assessed the clinical and radiological outcomes and analyzed the direction and grade...
متن کاملBiomechanical study of the funnel technique applied in thoracic pedicle screw replacement.
BACKGROUND Funnel technique is a method used for the insertion of screw into thoracic pedicle. AIM To evaluate the biomechanical characteristics of thoracic pedicle screw placement using the Funnel technique, trying to provide biomechanical basis for clinical application of this technology. METHODS 14 functional spinal units (T6 to T10) were selected from thoracic spine specimens of 14 fres...
متن کاملPedicle screw placement in patients with variant atlas pedicle
OBJECTIVE To investigate how the anatomy of variant atlas vertebra impacts on the strategy used to place pedicle screws used to treat atlantoaxial instability. METHODS The study enrolled patients with cervical instability who had a posterior arch pedicle height <3.5 mm at the anchor point, a vertebral artery groove height <3.5 mm, or both. Pedicle screws were fitted according to the anatomy o...
