Introduction: Previous studies have indicated that exposure to heavy metals related to bone health is primarily limited to some common harmful metals, and the impact of lead has not been fully understood. This study aims to explore the relationship between urine lead exposure and bone density.
Methods: 1,310 adults were included from the NHANES database (2015-2018), and through generalized linear regression analysis and constrained cubic spline models, the association between lead levels and total bone density as well as lumbar spine bone density was explored.
Objective: As the population ages and technology advances, lateral lumbar intervertebral fusion (LLIF) is gaining popularity for the treatment of degenerative lumbar scoliosis (DLS). This study investigated the feasibility, minimally invasive concept, and benefits of LLIF for the treatment of DLS by observing and assessing the clinical efficacy, imaging changes, and complications following the procedure.
Methods: A retrospective analysis was performed for 52 DLS patients (12 men and 40 women, aged 65.
Objective: Although the role of anterior cervical titanium plate system in stabilizing the spine sequence and promoting bone graft fusion has been widely recognized, more and more attention has been paid to the design of the plate itself and the complications caused by it. In order to solve the problems of poor stability of internal fixation, plate displacement and screw looseness, we designed the new PRUNUS spine plate system. Hence, the present study was conducted to describe observe and evaluate the clinical efficacy of a new type of three-leaf reinforced cervical anterior screw plate system (PRUNUS nailing system) developed for anterior cervical surgery.

- - The study aimed to assess the safety and effectiveness of 3D-printed interbody fusion cages used in anterior cervical discectomy and fusion (ACDF) for patients with cervical spondylotic myelopathy (CSM), focusing on mid- and long-term outcomes.
- - A total of 30 patients, with an average age of 60.22 years, underwent surgery and were monitored for an average of 65.23 months; their clinical improvement was measured using various scores and measurements before and after the procedure.
- - Results showed significant improvements in neurological function and quality of life, with a fusion rate of 100%, minimal changes in spinal height, and no major complications reported during follow-up. *
Objective: To analyze correlations between the selection of microtitanium plates with different specifications for use in a cervical vertebral dome expansion laminoplasty.
Methods: Sixteen patients that underwent the cervical vertebral dome expansion laminoplasty with a cervical spinal stenosis angioplasty procedure for treatment of their cervical spinal cords were recruited at our hospital. From February 2017 to September 2018, medical records confirmed that all patients underwent cervical CT and MRI tests pre- and postsurgery.
Article Synopsis
- The study investigates a new spinal surgery technique called full lamina back shift spinal canal enlargement for treating cervical spondylotic myelopathy.
- A comparison was made between 32 patients who underwent this new technique and 32 patients who had a traditional internal fixation procedure, analyzing imaging data for effectiveness.
- Results showed that the new technique resulted in significantly larger spinal canal dimensions and effective decompression, with minimal complications, demonstrating its clinical efficacy compared to the traditional method.
Objective: To develop a new type of open dynamic cervical spine system and study its biomechanical properties.
Methods: Ten fresh goat spine specimens were used in this study. Using high precision digital display grating displacement sensor system, a new type of open dynamic nail plate fixation was compared with Atlantis nail plate fixation in terms of the stability of cervical vertebrae, pull-out strength, and fatigue strength.
Objective: To observe and evaluate the clinical curative effect of a new type of open-powered cervical spine system developed for anterior cervical surgery.
Methods: A retrospective analysis was performed in our hospital in 2015-2017 of 329 orthopaedic patients treated with cervical anterior decompression, cage or titanium mesh graft fusion, new open-powered nail plate or traditional cervical anterior screw plate. A total of 154 (control group) and 175 (observation group) cases were fixed with conventional cervical- and new open-powered nail plates, respectively.
Influence of extending expansive open-door laminoplasty to C1 and C2 on cervical sagittal parameters.
BMC Musculoskelet Disord
February 2020
Article Synopsis
- The study examines the effects of expanding expansive open-door laminoplasty (EODL) to include C1 and C2 for treating cervical spinal stenosis, addressing limitations of the standard procedure which only targets C3-7.
- A retrospective analysis of 33 patients showed significant improvements in cervical angles and spinal alignment, particularly in the C2-7 Cobb angle and the T1-slope after one year post-surgery.
- Neurological function also improved significantly, with JOA scores indicating a 91.6% enhancement in patient outcomes, demonstrating the effectiveness of the extended procedure.
Objective: To investigate the efficacy and safety of ultrasonic bone curette in treating thoracic spinal stenosis.
Methods: A total of 30 patients of thoracic spinal stenosis who underwent posterior thoracic decompression in the hospital from December 2015 to 2017 were enrolled. Of these, 18 patients (group A) underwent posterior thoracic decompression using ultrasonic bone curette; and 12 patients underwent the treatment using a high-speed drill (group B).
