Objective: This study was performed to assess the efficacy of a novel tool to assist transpedicular bone grafting in short-segment pedicle screw fixation combined with pedicle fixation at the level of the fractured vertebra (six-screw fixation).
Methods: We retrospectively analyzed 80 patients (40 in the control group and 40 in the tool-aided group) with single-level thoracolumbar fractures. Patients in the control group underwent traditional six-screw fixation combined with transpedicular bone grafting. In the tool-aided group, we introduced a novel vertebroplasty tool to assist transpedicular bone grafting. Basic information and related indicators were recorded.
Results: There were no significant differences in the patients' baseline characteristics or surgical outcomes between the control group and tool-aided group. Both traditional surgery and tool-aided surgery restored the height of the fractured vertebrae and decreased the Cobb angle, visual analog scale score, and Oswestry Disability Index. However, tool-aided surgery more effectively restored the height of the fractured vertebrae and reduced the visual analog scale score and Oswestry Disability Index than did traditional surgery.
Conclusion: Vertebroplasty tool-aided surgery facilitated more precise and successful grafting of bone into damaged vertebrae than did traditional surgery and therefore might be recommended for treating single-level thoracolumbar fractures.

Background: Fractures of thoracolumbar spine in the field of ankylosing diseases such as ankylosing spondylitis (AS) and diffuse idiopathic skeletal hyperostosis (DISH) can by surgically treated with miniinvasive posterior transpedicular fixation. The exact length of implant is the subject of several studies. In our study, we retrospectively evaluated the treatment of B3 fractures of the ankylosed thoracolumbar spine with use a shorter versus longer implant, always with 8 screws.

Objective: Proximal junctional kyphosis (PJK) is a prevalent postoperative complication after posterior hemivertebra (HV) resection. Previous research has demonstrated a strong correlation between the development of PJK and reduced bone mineral density. The vertebral bone quality (VBQ) score, derived from magnetic resonance imaging, is considered a predictive and evaluative tool for bone mineral density.

Article Synopsis
- The study aimed to evaluate how the distribution of bone cement during percutaneous vertebroplasty (PVP) affects patients' residual back pain after surgery.
- A total of 65 patients with osteoporotic vertebral fractures underwent PVP, split into two groups based on the distribution of cement: 20 had it biased to one side (partial group) and 45 had it filling the vertebral body midline (bilateral group).
- Results showed that while both groups experienced pain relief post-surgery, the bilateral group had significantly lower pain levels at 1 day, 1 month, and 3 months after the procedure, highlighting that proper cement distribution is crucial in reducing residual back pain.

Article Synopsis
- The study aimed to assess the feasibility, safety, and early effectiveness of a minimally invasive surgical technique called the trench technique for treating central calcified thoracic disc herniation (CCTDH) and thoracic ossification of the posterior longitudinal ligament (T-OPLL).
- Seven patients were analyzed retrospectively, all of whom underwent successful surgery with an average age of 51.7 years; the outcomes were measured using various clinical scores, including pain (VAS) and functional recovery (JOA).
- Results showed all surgeries were completed without complications, with a reasonable average operation time of about 80 minutes, minimal blood loss, and short postoperative hospital stays, suggesting the procedure is both effective and safe.
Vertebral augmentation: How we do it.

Vertebral augmentation consists of minimally invasive techniques indicated in the treatment of vertebral compression fractures (VCFs). These compression fractures cause vertebral body height loss and consequent significant pain and are most frequently the result of osteoporosis, cancer metastasis, or trauma. The deleterious effects of VCFs often compound, as greater load-bearing stress is transferred to the remaining healthy vertebrae.
