Background context A persistent challenge in spine surgery is improving screw fixation in
patients with poor bone quality. Augmenting pedicle screw fixation with cement appears to …

Purpose The need for spinal instrumented fusion in osteoporotic patients is rising. In this
review, we try to give an overview of the current spectrum of pedicle screw augmentation …

Study Design: Retrospective study. Objective: To investigate the incidence, risk factors, and
outcomes of pedicle screw loosening in degenerative lumbar scoliosis (DLS) undergoing …

Objective To investigate risk factors for S1 screw loosening after lumbosacral fusion,
including spinopelvic parameters and paraspinal muscles. Methods We studied with 156 …

Background When choosing S1 as the lowest level of instrumentation, there are many
complications may come out such as S1 screw loosening. Facing this problem, there has …

Background Vertebroplasty prefilling or fenestrated pedicle screw augmentation can be
used to enhance pullout resistance in elderly patients. It is not clear which method offers the …

Abstract Background Patients with L4–S1 lumbar degenerative disease (LDD) with
osteoporosis are prone to sacral-screw loosening during spinal internal fixation. We aimed …

Background/objective Both polymethylmethacrylate (PMMA) and traditional calcium
phosphate–based cements have some deficiencies as augmentation materials for pedicle …

The adequacy of screw anchorage is a critical factor in achieving successful spinal fusion.
This study aimed to use machine learning algorithms to identify critical variables and predict …

Study Design: This is a prospective, randomized trial. Objective: This study aimed to
evaluate the outcome of bracing following transforaminal lumbar interbody fusion (TLIF) in …
