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.

[Mechanism of Huoxue Dingxuan Capsules on autophagy in vascular endothelial cells based on "crosstalk" of Bcl-2 and mTOR protein].

This paper investigated the mechanism of Huoxue Dingxuan Capsules(HXDX) on autophagy in vascular endothelial cells based on the "crosstalk" of Bcl-2 and mTOR protein. bEnd.3 cells were divided into a blank control group, a model group, and an HXDX group.

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.

[Application status and considerations of unilateral biportal endoscopy technique].

Objective: To review the application status, clinical advantages, and complications of unilateral biportal endoscopy (UBE) technique and explore its future development direction.

Methods: By reviewing recent domestic and international literature, the evolution history of UBE technique, its surgical advantages, and its application effectiveness in various spinal diseases were analyzed, providing a comprehensive review.

Results: UBE technique, with its unique dual-channel design, provides a clearer surgical field and more flexible operating space, significantly reduces surgical trauma and postoperative recovery time.

[Incidence and risk factors of postoperative epidural hematoma following anterior cervical spine surgery].

Objective: To investigate the incidence and potential risk factors associated with postoperative spinal epidural hematoma (SEH) following anterior cervical spine surgery (ACSS).

Methods: A retrospective analysis was conducted on the clinical data of patients who underwent ACSS for cervical spondylosis at Peking University Third Hospital between March 2013 and February 2022. Patients who developed postoperative SEH were categorized as the SEH group, while those in the cohort without SEH were randomly selected as the non-SEH group by individually matching with the same operator, same gender, same surgery year, and similar age (±5 years) at a ratio of 4 ∶ 1.

Comparison of Pain and Functional Outcomes Among Geriatric and Nongeriatric Adults Following Full Endoscopic Spine Surgery for Degenerative Lumbar Pathology.

Background: Full endoscopic spine surgery (FESS) champions a rapid recovery and a low rate of overall complications. However, its efficacy in geriatric patients that might yield additional benefits from minimized invasiveness remains underexplored.

Methods: A multi-institutional prospective cohort study was conducted involving patients undergoing elective lumbar FESS.

Lumbosacral transitional vertebrae in small-breed dogs: Prevalence, classification, and characteristics.

The lumbosacral transitional vertebra (LTV) is an abnormally formed vertebra that can be associated with cauda equina syndrome, lumbosacral (LS) degeneration, and pelvic rotation. However, there is little information on LTV in small-breed dogs, and no studies have investigated the association between LTV and LS diseases or degenerative changes in the coxofemoral joints. The purpose of this multicenter, retrospective, and cross-sectional study was to determine the prevalence of LTV in small-breed dogs (<10 kg), classify the type of LTV, and identify its association with degenerative changes in the LS and coxofemoral joints using CT images.

[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.

Development of a deep learning model for automatic detection of narrowed intervertebral disc space sites in caudal thoracic and lumbar lateral X-ray images of dogs.

Intervertebral disc disease is the most common spinal cord-related disease in dogs, caused by disc material protrusion or extrusion that compresses the spinal cord, leading to clinical symptoms. Diagnosis involves identifying radiographic signs such as intervertebral disc space narrowing, increased opacity of the intervertebral foramen, spondylosis deformans, and magnetic resonance imaging findings like spinal cord compression and lesions, alongside clinical symptoms and neurological examination findings. Intervertebral disc space narrowing on radiographs is the most common finding in intervertebral disc extrusion.

Comparison of Disc Degeneration between Pyogenic Spondylitis and Noninfected Lumbar Spondylosis: A Multicenter Retrospective Study with Propensity Score Matching.

Introduction: Disc degeneration is a risk factor of pyogenic spondylitis. However, its degree in patients with pyogenic spondylitis is unknown. This study aimed to determine differences in disc degeneration between patients with pyogenic spondylitis and those with noninfectious lumbar spondylosis.

Safety and efficacy of aggressive exercise therapy for patients with unilateral early-stage spondylolysis: A retrospective comparative cohort study.

Introduction: Bony union in patients with early-stage spondylolysis can be achieved using a rigid corset and avoiding sports activities. However, prolonged absence from sports activities may decrease physical fitness. This study aimed to investigate the safety and efficacy of aggressive exercise therapy for patients with early-stage spondylolysis (ESS).

Study Design: Cross-sectional, observational study.

Objective: Investigate the frequency of intraoperative neuromonitoring (IONM) utilization among Medicare patients diagnosed with cervical spondylosis (CS), both with and without myelopathy.

Background: IONM is widely used as a tool in spine surgery.
