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...
متن کاملPedicle 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...
متن کاملCement Augmentation of Sacral Pedicle Screw Fixation
As an alternative to PMMA, a newly developed calcium triglyceride bone cement (CTBC) (Kryptonite, Doctors Research Group, USA) has been reported to have osteoconductive properties [2]. In addition, CTBC is adhesive, non-toxic, and low exothermic, all of which would be advantageous in vivo. It has also been shown to have a modulus of elasticity very similar to bone, which is drastically differen...
متن کاملFree 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...
متن کاملA biomechanical comparison of a novel thoracic screw fixation method: transarticular screw fixation vs traditional pedicle screw fixation.
BACKGROUND Transarticular screw fixation is used in the upper cervical and lumbar spine to achieve posterior spinal stability, and its biomechanical performance has been proven to be similar to that of pedicle screw fixation. However, few studies have reported the use of transarticular screw fixation in the upper thoracic spine. OBJECTIVE To biomechanically compare transarticular screws with ...
