Kinematic status of Bryan and Mobi-C artificial cervical discs post cervical hybrid surgery: a retrospective study.

Objective: To examine the mid-term efficacy and imaging results of using the Mobi-C and Bryan implants after cervical hybrid surgery for 2-level cervical spondylolisthesis, and to observe their postoperative changes and differences in the flexion-extension center of rotation (FE-COR) for the anterior cervical disc replacement (ACDR) segment.

Methods: Patients who underwent cervical hybrid surgery between June 2014 and June 2019 were included in this study. The mJOA, NDI, and VAS scores were used to assess clinical outcomes, and the FE-COR of the ACDR segment was measured.

Association between modifiable and nonmodifiable risk factors with paralumbar muscle health in patients with lower back pain.

Background: Prior studies have linked sarcopenia and fat infiltration in paraspinal muscles with lumbar pain, spinal pathology, and adverse postoperative outcomes in lumbar spine surgery. A recent magnetic resonance imaging (MRI)-based method for assessing muscle health, incorporating parameters such as Goutallier Classification (GC) and the Paralumbar Muscle Cross-Sectional Area to Body Mass Index ratio (PL-CSA/BMI), has shown that higher muscle grades correlate with significant improvements in patient-reported outcomes. Despite these advancements, there is limited research on the associations between paralumbar muscle health and factors such as age, BMI, walking tolerability, and spondylolisthesis.

Comparative efficacy and fusion outcomes of unilateral bi-portal endoscopic transforaminal lumbar interbody fusion versus minimally invasive transforaminal lumbar interbody fusion in treating single-segment degenerative lumbar spondylolisthesis with lumbar spinal stenosis: a two-year retrospective study.

Background: Degenerative lumbar spondylolisthesis (DLS) with lumbar spinal stenosis (LSS) is a common condition resulting in substantial lower back pain and disability. Surgical intervention is recommended only when conservative treatment fails. This study compared UBE-TLIF and MIS-TLIF regarding clinical outcomes and fusion rates in patients with single-segment DLS with LSS.

Risk factors analysis and predictive model of degree I degenerative lumbar spondylolisthesis.

Study Design: Retrospective Case-Control Study.

Background: There have been some previous studies on the risk factors associated with lumbar spondylolisthesis, but there are few studies on the risk factors for disease progression in mild degenerative lumbar spondylolisthesis (DLS). To analyze the risk factors associated with aggravation of spondylolisthesis in patients with grade I degenerative spondylolisthesis and construct a prediction model.

[Therapeutic and diagnostic classification of degenerative spondylolisthesis: validation and multiple-center inter-observer agreement].

Object: To evaluate inter- and intra-observer agreement of the proposed diagnostic and treatment classification of degenerative spondylolisthesis.

Material And Methods: The proposed diagnostic and treatment classification of degenerative spondylolisthesis was validated according to the GRRAS protocol. For this purpose, we retrospectively analyzed MRI, CT and spinal radiography data in 20 patients.

Traumatic lumbosacral instability: part 1 - proposing a definition and identifying underlying injury patterns.

Traumatic lumbosacral instability (TLSI) generally refers to a traumatic disruption of the lumbopelvic junction. The ambiguous use of this term has contributed to confusion and limited understanding of injuries that can impact lumbosacral stability. As of now, TLSI lacks a clear definition, and the underlying injury patterns remain inadequately characterized.

Is There a Need for Functional Radiographs in Diagnosing Lumbar Instability?

Study Design: Retrospective radiological database analysis.

Objective: The aim of this study was to assess the value of functional radiography (FRF = flexion; FRE = extension) compared to MRI and standing sagittal plane full spine radiography (SP) with low-grade spondylolisthesis.

Methods: Sagittal translation (ST) and rotation (SR) were measured between all lumbar levels to assess instability.

Letter to the editor concerning "Erector Spinae could be the game changer in surgical decision-making in patients with lumbar spondylolisthesis: a cross-sectional analysis of an age-, sex-, subtype-, level-matched patients with similar spinopelvic parameters received surgical or conservative management" by M.S. Eksi, et al. (Eur Spine J [2024]: doi: 10.1007/s00586-024-08341-3).

The letter responds to a study on the role of erector spinae muscle quality in surgical decision-making for lumbar spondylolisthesis. It highlights the potential of paraspinal muscle fatty infiltration as a predictive factor, suggesting that early rehabilitation targeting these muscles may reduce the need for surgery. The authors propose improvements for future research, such as using advanced MRI techniques for better fat infiltration assessment, controlling patient activity levels, and incorporating multidimensional imaging analyses with machine learning.

External validation of SpineNetV2 on a comprehensive set of radiological features for grading lumbosacral disc pathologies.

Background: In recent years, the integration of Artificial Intelligence (AI) models has revolutionized the diagnosis of Low Back Pain (LBP) and associated disc pathologies. Among these, SpineNetV2 stands out as a state-of-the-art, open-access model for detecting and grading various intervertebral disc pathologies. However, ensuring the reliability and applicability of AI models like SpineNetV2 is paramount.

The Effect of Selective Dorsal Rhizotomy on Scoliosis in Children With Cerebral Palsy: A Long-term Follow-up Study.

Background: Selective dorsal rhizotomy (SDR) is commonly used to reduce spasticity in children with cerebral palsy (CP). Children with CP have an increased risk of spinal deformities that increase with age and Gross Motor Function Classification System (GMFCS) level. Few studies have considered the risk of spinal deformity post-SDR by GMFCS level.

Impact of joint hypermobility on lumbar positional changes in back pain patients: a cross-sectional weight-bearing MRI study.

Purpose: To investigate positional lumbar changes by weight-bearing MRI in low back pain (LBP) patients with hypermobile joints (Beighton score ≥ 4).

Methods: Patients referred to weight-bearing MRI went through a clinical examination, including Beighton's test, answered back pain-related questionnaires, and were hereafter imaged in supine and standing in a 0.25-T MRI unit.

Lumbar Spinal Rahisynthesis with Plif: a Retrospective Study of 58 Patients Demonstrating Imaging and Clinical Outcomes with One Year Follow-up.

Background/objectives: Nowadays, posterior lumbar cages remain a popular choice among the available options for interbody fusion even when compared with anterior approaches. As the posterior lumbar anatomy permits a relatively easy exposure to the spinal anatomy of interest, expandable cages prove to be a reliable tool for 360-degree fusion. Our study aspires to investigate the postoperative effects of Flarehawk 9 after open posterior lumbar fixation.

Magnetic resonance imaging (MRI) computed tomography (CT) in the diagnosis and classification of spondylolysis and spondylolisthesis-a narrative review.

Background And Objective: Spondylolysis is a lysis of the pars interarticularis, a component of the posterior arch of the vertebral body, in the face of repeated overuse and stress phenomena generally associated with sports in children and adolescent patients. This entity is one of the most common causes of low back pain in this age group. The diagnosis can be made using various imaging techniques, with computed tomography (CT) being considered the gold standard, as it provides the best visualization of the fracture, its extension and orientation, as well as an assessment of the entire bony skeleton.

Mid-term efficacy of non-contact orthopedic robot navigation in the treatment of lumbar spondylolisthesis.

Objective: This study was aimed to explore the mid-term efficacy of non-contact orthopedic robot navigation in the treatment of lumbar spondylolisthesis.

Methods: The clinical data of young and middle-aged patients with lumbar spondylolisthesis were retrospectively analyzed and divided into an observation group and a control group according to surgical methods. The observation group was treated with minimally invasive transforaminal interbody fusion (MIS-TLIF) combined with orthopedic robot-navigated percutaneous pedicle screw fixation; while the control group underwent traditional posterior lumbar interbody fusion (PLIF).
