Guided pedicle screw insertion: techniques and training.
BACKGROUND CONTEXT In spinal fusion surgery, the accuracy with which screws are inserted in the pedicle has a direct effect on the surgical outcome. Accurate placement generally involves considerable judgmental skills that have been developed through a lengthy training process. Because the impact of misaligning one or more pedicle screws can directly affect patient safety, a number of navigatio...
متن کاملTrue anteroposterior view pedicle screw insertion technique
BACKGROUND The wide use of minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) surgery in the treatment of degenerative disc disease of lumbar spine in spinal surgery highlights the gradual decrease in the use of traditional pedicle screw insertion technology. This study aims to analyze the accuracy of the true anteroposterior view pedicle screw insertion technique in MIS-TLIF ...
متن کاملPedicle screw malposition following spinal lumbar injury
Pedicle screws are the main type of instrumentation used in the lumbar spine via the posterior approach. The accuracy of their insertion is always a concern because the malposition of screws is associated with a potential risk of iatrogenic injury of any neurovascular structure they pass. Fortunately, spinal cord and cauda equina injuries are rare. This 18-year-old paraplegic woman presented mo...
متن کاملBiomechanical analysis of differing pedicle screw insertion angles.
BACKGROUND Pedicle screw fixation to stabilize lumbar spinal fusion has become the gold standard for posterior stabilization. A significant percentage of surgical candidates are classified as obese or morbidly obese. For these patients, the depth of the incisions and soft tissue makes it extremely difficult to insert pedicle screws along the pedicle axis. As such, the pedicle screws can only be...
متن کاملImproved accuracy of computer-assisted cervical pedicle screw insertion.
OBJECT The authors introduce a unique computer-assisted cervical pedicle screw (CPS) insertion technique used in conjunction with specially modified original pedicle screw insertion instruments. The accuracy of screw placement as well as surgery-related outcome and complication rates were compared between two groups of patients: those in whom a computer-assisted and those in whom a conventional...
