Analysis of the characteristics of spino-pelvic sagittal parameters in Degenerative Thoracolumbar Kyphosis deformity and the mechanism of sagittal imbalance

Ruifeng Xun, Liang Zhao, Weixing Han, Gang Chen et autres

BACKGROUND: Degenerative thoracolumbar kyphosis (DTLK) is a subtype of adult spinal deformity. If DTLK progresses further, it can develop into global kyphosis (GK). Although numerous studies have described the sagittal parameters of the spino-pelvic in adult spinal deformities, there is currently no …

Clinical application of a dual-surface, four-edge 3D-printed pedicle screw guide in adolescent idiopathic scoliosis surgery: a retrospective comparative study

Yifei Li, Xiubo Ge, Jian Wang, Wei Zhang et autres

Accurate pedicle screw placement is essential for safety in scoliosis correction surgery. Conventional freehand techniques are operator-dependent, while navigation-assisted techniques may increase intraoperative imaging requirements and workflow complexity. Patient-specific 3D-printed drill guide templates have been proposed to improve accuracy and reduce imaging …

Imaging observation of intervertebral disc degeneration in patients with old thoracolumbar fracture-related kyphotic deformity

Xilong Cui, Ao Ding, Wen Yin, Wei Zhang et autres

Old thoracolumbar fracture with kyphosis (OTLFK) often results in low back pain, with intervertebral disc degeneration being a significant contributor. We hypothesized that patients with OTLFK exhibit distinct patterns of disc degeneration compared to those with chronic low back pain without kyphotic …

Characteristics and mechanical mechanisms of intervertebral disc degeneration in old thoracolumbar fractures with kyphosis: clinical observations and finite element analyses

Xilong Cui, Ao Ding, Junjun Zhu, Wei Zhang et autres

BACKGROUND: Low back pain is a common complication in patients with old thoracolumbar fractures with kyphosis (OTLFK), and intervertebral disc degeneration (IDD) is a major contributor. Mechanical abnormalities are believed to play a key role in the development to IDD. This study …

A new mathematical model for evaluating surface changes in the mid-abdominal sagittal plane after two-level pedicle reduction osteotomy in patients with ankylosing spondylitis

Wen Yin, Guohui Zheng, Wei Zhang, Yunlei Zhai et autres

BACKGROUND: The purpose of this study was to create a mathematical model to precalculate the acreage change in the abdominal median sagittal plane (ac-AMSP) of patients with ankylosing spondylitis (AS) for whom two-level pedicle subtraction osteotomy (PSO) was planned. METHODS: A single-centre …

Operative strategies for ankylosing spondylitis-related thoracolumbar kyphosis: focus on the cervical stiffness, coronal imbalance and hip involvement

Wei Zhang, Wen Yin, Xilong Cui, Zihao Chai et autres

BACKGROUND: Cervical stiffness, coronal imbalance and limited hip movement all play crucial roles in designing the corrective surgery for ankylosing spondylitis-related thoracolumbar kyphosis (AS-TLK). However, a comprehensive classification and tailored strategies for directing clinical work are lacking. This study aims to investigate …
