Clinical Effect of Minimally Invasive Percutaneous Pedicle Screw Internal Fixation Combined with Injured Vertebrae Bone Grafting in the Treatment of Thoracolumbar Fractures in Orthopedic Surgery

Abstract

Objective. To observe the clinical effect of minimally invasive percutaneous pedicle screw internal fixation combined with injured vertebrae bone grafting in the treatment of thoracolumbar fractures in orthopedic surgery. Methods. A total of 132 patients with thoracolumbar fractures admitted to the hospital were enrolled between January 2020 and April 2021. Both groups underwent minimally invasive percutaneous pedicle screw internal fixation. According to the presence or absence of intraoperative injured vertebrae bone grafting, they were divided into the grafting group (73 cases) and the injured vertebrae ungrafted group (59 cases). The perioperative indexes, pain at 2 weeks after surgery, surgical stress, recovery of an injured vertebra, self-care ability, quality of life, and postoperative complications were compared between the two groups. Result. There was no significant difference in intraoperative blood loss, operation time, or hospitalization time between the grafting group and the nongrafting group ( P > 0.05 ).2 weeks after surgery, scores of the Visual Analogue Scale (VAS) in the grafting group were lower than those in the nongrafting group ( P < 0.05 ).At 3d after surgery, levels of serum cortisol (COR), epinephrine (E), and norepinephrine (NE) in both groups were higher than those before surgery, which were lower in the grafting group than in the nongrafting group ( P < 0.05 ).At 3 months after surgery, the anterior edge height of the injured vertebra in both groups was increased, which was higher in the grafting group than in the nongrafting group ( P < 0.05 ). At 3 months after surgery, the Cobb angle of sagittal kyphosis in both groups was decreased, which was lower in the grafting group than that in the nongrafting group ( P < 0.05 ). At 3 months after surgery, the scores of activity of daily living (ADL) and the MOS item-short form health survey (SF-36) in both groups were higher than those before surgery, which were higher in the grafting group than in the nongrafting group ( P < 0.05 ). The difference in the incidence rate of injured vertebrae collapse, internal fixation breakage, or kyphosis between the grafting group and the nongrafting group was not statistically significant (1.37% vs 6.78%) ( P > 0.05 ). Conclusion. Minimally invasive percutaneous pedicle screw internal fixation combined with injured vertebrae bone grafting in orthopedic surgery can improve postoperative pain and surgical stress in patients with thoracolumbar fractures, which is conducive to the recovery of injured vertebrae and improvement in the quality of life.

A Clinical Comparative Study on Percutaneous and Open Approaches for Screw Internal Fixation in Treating Thoracolumbar Fractures

“…The empty shell of the vertebral body will lead to the increase of the gap of the anterior column, the reduction of the load-bearing capacity, and the transfer of stress to the posterior fixation system, leading to the fracture or loosening of the internal fixation system. 18 The results of this study showed that the incidence of empty shell signs in the study group was lower than that in the control group during follow-up (all ps < 0.05). This may be because the upper and lower vertebral body placement of fixed screws can reconstruct the height of the cone, consolidate the correction effect of internal fixation, and then reduce the occurrence of adverse reactions such as fracture and fall off of internal fixation.…”

“…pointed out that percutaneous pedicle screw combined with injured screw can more effectively reconstruct spinal physiological sequences and maintain spinal stability 17 . Fei's research points out that minimally invasive percutaneous pedicle screw surgery could improve postoperative pain and surgical stress in patients with thoracolumbar fractures, which was beneficial for the recovery of injured vertebrae and the improvement of quality of life 18 . The results of the present study suggested that one universal screw placed percutaneously in the injured vertebral body, while fixed screws placed in the adjacent upper and lower vertebral bodies could significantly relieve the pain of patients with thoracolumbar fractures in the early postoperative period and reduce postoperative complications.…”

“…The vertebral anterior column is to maintain the stability of the spine structure, bear most of the weight percentage. The empty shell of the vertebral body will lead to the increase of the gap of the anterior column, the reduction of the load‐bearing capacity, and the transfer of stress to the posterior fixation system, leading to the fracture or loosening of the internal fixation system 18 …”
