Objective: To investigate the effect of titanium ring cage implantation on cervical foraminal area and intervertebral height.
Methods: Twenty-two patients with single level cervical disc herniation were enrolled in this study. All patients underwent a standard anterior cervical discectomy followed by titanium ring cage implantation. Radiographs were used for evaluation of the cervical foraminal area and intervertebral height in the pre- and postoperative periods.
Results: Mean intervertebral heights were 0.7 +/- 0.1 cm (preoperative), 1.1 +/- 0.2 cm (early postoperative) and 0.9 +/- 0.2 (final measurement). Increase in intervertebral height at final follow-up was 0.2+/-0.1 cm (22.6+/-8.5%). Mean cervical foraminal areas were 0.4+/-0.1 cm2 (preoperative), 0.5 +/- 0.2 cm2 (early postoperative) and 0.5 +/- 0.1 cm2 (final measurement). Increase in cervical foraminal area at the final follow-up was 0.1 +/- 0.1 cm2.
Conclusion: Our study demonstrates that cervical intervertebral height and cervical foraminal area significantly increased after cervical ring cage placement but subsidence during the follow-up period negatively affects foraminal area. However, overall, there was a relative increase of foraminal area and intervertebral height when compared with preoperative values. Long-term follow-up is required to further assess the subsidence rate.

Facet joint tropism in degenerative lumbar scoliosis: a retrospective case-control study.
Spine Deform

Gastroenterology and Hepatology Research Center, Institute of Basic and Clinical Physiology Sciences, Kerman University of Medical Sciences, Kerman, Iran.
Background: To investigate the association between lumbar degenerative scoliosis and the dural sac cross-sectional area (DSCA), the lumbar canal anterior-posterior (LCAP) diameter, and the neural foraminal cross-sectional area (NFCA) in relation to facet joint tropism (FJT).
Methods: In a retrospective case-control study, we analyzed data from 160 patients referred for lumbar magnetic resonance imaging (MRI) between January 2020 and December 2022. Cobb's angle on anteroposterior lumbosacral X-ray is served to identify the presence of degenerative lumbar scoliosis-Cobb's angle exceeding 10 degrees-, and axial T2W MRI is implemented to evaluate facet joint angles and tropism-defined as a difference exceeding 10 degrees between the facet joint angles at each level-, DSCA, LCAP, and NFCA.
Transforaminal Endoscopic Lumbar Foraminotomy for Iatrogenic Foraminal Stenosis Following Vertebroplasty.

We present a case of iatrogenic lumbar foraminal stenosis caused by bone-cement leakage during vertebroplasty, successfully managed using transforaminal endoscopic lumbar foraminotomy (TELF). Vertebroplasty is an effective treatment for osteoporotic vertebral compression fractures (VCFs); however, complications such as bone-cement leakage can lead to vascular or neurological issues, including lumbar radiculopathy. TELF is a minimally invasive surgical option for addressing various forms of lumbar foraminal stenosis.

Study Design: Matched case-control study.
Purpose: To evaluate the midterm outcomes of unilateral pedicle screw fixation (UPSF) versus bilateral pedicle screw fixation (BPSF) in transforaminal lumbar interbody fusion (TLIF) procedure, ascertain efficacy of UPSF in adequately decompressing contralateral foramen+spinal canal and reducing rate of adjacent segment degeneration (ASD) at 4-8-year follow-up (FU).
Overview Of Literature: Previous meta-analyses found no significant differences between UPSF and BPSF regarding fusion rates, clinical and radiological outcomes; however, few studies have reported higher rates of cage migration/subsidence and pseudoarthrosis in the UPSF.

Introduction: The normative relationship between lumbar intervertebral disc space height (DSH) and neuroforaminal dimensions (NFD) has yet to be defined.
Research Question: The purpose of this study was to investigate the relationship between lumbar DSH and NFD using computed tomography (CT), accounting for influences of patient demographic and anthropometric characteristics.
Materials And Methods: We analyzed CT imaging of 350 female and 350 male patients.
Sequential Anterior Longitudinal Ligament Release With Expandable Spacers for Lordosis Correction in Anterior-to-Psoas Lumbar Interbody Fusion: A Radiographic and Biomechanical Study.
Int J Spine Surg

Department of Scientific Affairs, Globus Medical, Inc., Audubon, PA, USA.
Background: Anterior column realignment is an attractive minimally invasive treatment for sagittal imbalance. Expandable spacers offer controlled tensioning of the anterior longitudinal ligament (ALL) during release, which could optimize correction and anterior column stability. This study investigated the biomechanical and radiographic effects of single-level anterior-to-psoas lumbar interbody fusion (ATP-LIF) with expandable spacers and sequential ALL release.
