Pedicle Screw Instrumentation of the Thoracic Spine in Idiopathic Scoliosis

Abstract

Pedicle or vertebral body cortical penetration occurred with 25% of the screws but with no neurologic compromise. Curve correction was slightly greater than with hooks, but not to a statistically significant extent.

Adolescent idiopathic thoracic scoliosis: apical correction with specialized pedicle hooks

“…Our Cobb angle correction was 67% postoperatively and 58% on average at the last follow-up. This compares favorably with the Liljenqvist series [17], where 59% of curve correction was achieved using mainly pedicle screws. It is known that one of the main factor that determines correctability is the flexibility of the curve [7].…”

“…The best vertebral fixation is well known to be achieved with pedicle screws. This has been used in the correction of AIS by Suk et al [24] and Liljenqvist et al [17], who documented better corrections in their pedicle screw groups than in their hook only groups. Both reported excellent correction using such techniques (72% of Cobb angle correction for Suk and 59% for Liljenqvist).…”

Use of computed tomographic reconstruction to establish the ideal entry point for pedicle screws in idiopathic scoliosis

“…In the treatment of spinal deformity, the use of the pedicle screw has been gaining increasing acceptance among the surgeons [1]. The implantation of pedicle screws with spinal instrumentation has shown to have improved coronal, sagittal and rotational deformity correction [2].…”

CT Provides Precise Size Assessment of Implanted Titanium Alloy Pedicle Screws

“…The use of thoracic pedicle screws in the treatment of pediatric spinal deformity has increased in popularity [3,10,15,20,27,34]. Several studies have been devoted to developing safe techniques for screw placement [3,5,8,9], whereas others focus on anatomic structures at risk during screw placement [5, 7, 12, 16, 19-22, 29, 30, 32, 33].…”

“…The use of pedicle screws for treatment of spinal deformities has increased in popularity [3,10,15,20,27,34]. Pedicle screws are purported to provide several advantages over other available implants: higher pullout strength, ability to save distal fusion levels, better apical vertebral derotation, and improved curve correction, to name a few.…”
