Article Synopsis
- - The study created a detailed 3D model of the lower lumbar spine (L3-S1) to analyze how different fixation methods affect the stability and stress during oblique lumbar interbody fusion (OLIF).
- - Four surgical models were tested: Stand-alone (SA), unilateral (UCBT), bilateral cortical bone trajectory (BCBT), and bilateral pedicle screws (BPS), with BCBT showing the least range of motion, indicating better stability, while SA had the highest ROM and cage stress.
- - Overall, using OLIF with internal fixation increased segment stability and reduced stress on cages, with BPS being particularly good for preventing damage and reducing risks of complications, while BCBT effectively maintained stability in
Background: This meta-analysis compares the efficacy of unilateral biportal endoscopic transforaminal lumbar interbody fusion (UBE-TLIF) to conventional interbody fusion in lumbar degenerative diseases (LDD).
Methods: An extensive literature search was conducted in PubMed, Web of Science, and the Cochrane Library. Research related to UBE-TLIF published up to November 2022 was reviewed.
Objective: To evaluate the early clinical efficacy of robot-assisted percutaneous short-segment bone cement-augmented pedicle screw fixation in the treatment of stageⅡ-Ⅲ Kümmell disease.
Methods: The clinical data of 20 patients with stageⅡ-Ⅲ Kümmell's disease who underwent robot-assisted percutaneous bone cement-augmented pedicle screw fixation between June 2017 and January 2021 were retrospectively analyzed. There were 4 males and 16 females, aged from 60 to 81 years old with an average age of (69.
Article Synopsis
- The study compared robot-assisted (RA) and freehand (FH) methods for pedicle screw fixation in treating thoracolumbar fractures to evaluate their accuracy and effectiveness.
- The RA group had longer operation times (138.69 min) but significantly less intraoperative blood loss (49.23 ml) compared to the FH group (103.67 min and 78.33 ml).
- Both methods showed significant improvement in vertebral height ratio post-operation, indicating that RA treatment effectively reduces fractures.
Background: Percutaneous kyphoplasty (PKP) or percutaneous vertebroplasty (PVP) are commonly employed for Kummell's disease in stages II-III; however, these techniques produce some complications.
Objective: To compare the clinical efficacy and imaging results of percutaneous vertebroplasty + bone cement-augmented short-segment pedicle screw fixation (PSPVP) versus transpedicular intracorporeal bone grafting + pedicle screw fixation (PSIBG) in the treatment of stage II-III Kummell's disease.
Methods: A total of 69 patients admitted between November 2017 and March 2021 were included in this study; 36 of these were treated with PSPVP, and 33 were treated with PSIBG.
The aim of this study was to evaluate the treatment efficacy of lateral spinal stenosis through the decompression of the nerve root under a multiple planar endoscope. From January 2017 to March 2019, 52 patients with lumbar spinal stenosis or lumbar spinal stenosis combined with intervertebral disc herniation had been treated via transforaminal approach spinal endoscopy. Our study retrospectively analyzed the treatment outcome.

In the present study, we investigated the possible mechanism of Vinp in alleviating of the progress of osteonecrosis of the femoral head (ONFH) both experiments. The results showed that treatment with Vinp suppressed the dexamethasone (Dex) induced over-regulation of ROS level and apoptotic factors.

The mechanism of degenerative intervertebral disc is very complex, which may be associated with multiple factors such as the mechanical stress force injury of intervertebral disc, nutritional deficiency, inflammatory stimulation, etc. Recently, many studies detected propionibacterium acnes(P. acnes) in degenerative intervertebral disc and supposed P.

However, the true efficacy of AOSF remains unclear. In this study, we aimed to provide the pooled rates of non-union, reoperation, infection, and approach related complications after AOSF for odontoid fractures.

However, it is still unclear whether TLIF with unilateral pedicle screw (PS) fixation is as effective as that with bilateral PS fixation. We performed a meta-analysis of the literatures and aimed to gain a better understanding of whether TLIF with unilateral PS fixation was safe and effective for lumbar diseases.

Methods: Between January 2008 and December 2012, we retrospectively analysed a total of 131 patients who underwent decompressive surgery along with the Coflex system for the treatment of degenerative lumbar diseases. The related complications were reported, and appropriate measures were taken.
