TLDR
The vulnerability of Luque rod constructs to implant failure, from a mechanical standpoint, is greater than is generally assumed and methods to decrease tensile stresses in the implants and increase stiffness include external immobilization, larger diameter rods, and procedures to enhance correction.About:

Journal ArticleDOI
Early failure of short-segment pedicle instrumentation for thoracolumbar fractures. A preliminary report.
TL;DR: The high rate of failure of the hardware associated with this fixation construct suggests that posterior screw fixation alone may not be adequate when Cotrel-Dubousset instrumentation is used for short-segment lumbar arthrodeses.
Journal ArticleDOI
The use of pedicle-screw internal fixation for the operative treatment of spinal disorders.
TL;DR: The Funnel Technique provides a straightforward, direct, and inexpensive way to very safely apply pedicle screws in the cervical, thoracic, or lumbar spine.

TL;DR: A multicenter, retrospective review of rod fracture in adult spinal deformity was performed in this article, where the authors evaluated symptomatic rod fracture after posterior instrumented fusion for adult spinal deformation.

TL;DR: There was a substantial range in the rate of RF with PSO across centers, suggesting potential variations in technique that warrant future investigation, and alternative instrumentation strategies should be considered for these cases.
Journal ArticleDOI
The biomechanics of long versus short fixation for thoracolumbar spine fractures.
TL;DR: An overview of biomechanical strengths and weaknesses of long and short fixation constructs applied in thoracolumbar fractures are provided, along with a discussion of specific indications for selecting an instrumentation construct for a given fracture.

TL;DR: The optimum approach establishes correctability of the deformity prior to spinal instrumentation, provides secure internal fixation of the spine, and strives for a massive arthrodesis.

Staged correction of neuromuscular scoliosis.

TL;DR: Anterior release and fusion, combined with tong gravity traction and second stage L-rod instrumentation, establishes correctability and accomplishes circumferential arthrodesis of the spine in neuromuscular scoliosis, which has the advantages of requiring no anterior instrumentation and no postoperative immobilization.
