Posterior pedicle screw fixation combined with transpedicular bone grafting for treatment of single-level thoracolumbar fractures with the aid of a vertebroplasty tool

Abstract

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.

A Randomized Controlled Trial: Short-Segment Posterior Fixation and Transpedicular Bone Grafting combined with rhBMP-2 for the Treatment of Thoracolumbar Burst Fracture

“…Additionally, the mechanical prying action of the "implantation hopper" can help reset the collapsed vertebral body, restore the height of the injured vertebrae, and achieve satisfactory correction of kyphosis, promoting bone healing. This can effectively reduce the neurological complications caused by bone defects and bone nonunion after surgery [30] . However, Kambin bone grafting has limitations such as puncturing into the injured vertebrae, redestruction of the vertebral bone cortex, cumbersome surgical steps, di culty in obtaining "bone grafting funnel" instruments, and prolonged surgical time.…”

Effect of Minimally Invasive Internal Arch Nailing Surgery on Tissue Traumatic Stress Response in Patients with Vertebral Fractures

“…Surgery can cause systemic stress response and muscle damage, which is a special stressor, and the CK levels of skeletal muscle, cardiac muscle, brain, and other tissue cells are significantly elevated, which can be used as an important indicator to determine muscle damage [ 22 ]. Patients experience significant muscle strain and fracture trauma during open arch root nail internal fixation surgery treatment, and plasma CK levels are significantly elevated [ 23 ]. Open arch root nail internal fixation surgical treatment requires paravertebral muscle distraction under the guidance of an automatic retractor, and paravertebral muscle ischemia is evident, which will further reduce the risk of lumbar back muscle ischemia and increase the pain level of patients [ 24 , 25 ].…”
