BACKGROUND:Anterior decompression, bone graft fusion, plate and screw fixation are commonly used in clinic for the treatment of thoracolumbar burst or comminuted fractures. The posterior surgery including decompression laminectomy and pedicle screw internal fixation.
OBJECTIVE:To explore the biomechanical changes of spine after thoracolumbar fracture and dislocation treated with pedicle screw internal fixation.
METHODS:Forty-six patients with thoracolumbar fracture and dislocation were treated with pedicle screw internal fixation, and then the recovery of spinal cord injury and fracture reduction were observed after internal fixation, immediately after internal fixation and 1-year fol ow-up.
RESULTS AND CONCLUSION:Al the 46 cases were fol owed-up. Frankel function classification assessment was used to evaluate the spinal cord injury grade. There was no significant difference in the percentage of A grade between periods (P>0.05), and there were significant differences in the percentage of B-E grades when compared between immediately postoperative period, 1-year fol ow-up period and preoperative period (P<0.05), but there was no significant difference when compared between immediately postoperative period and 1-year-fol ow period (P>0.05). The anterior height percentage, posterior height percentage and Cobb angle indicators were used to assess the fracture reduction, and the results showed there was no significant difference in posterior height between periods (P>0.05), and there was significant difference in Cobb angle when compared between immediately postoperative period, 1-year fol ow-up period and preoperative period (P<0.05), but there was no significant difference between immediately postoperative period and 1-year fol ow-up period (P>0.05). The results indicate that pedicle screw internal fixation system for the treatment of thoracolumbar spinal fracture and dislocation is conducive to the fracture reduction and functional recovery.

Lung cancer and chronic obstructive pulmonary disease (COPD) are two high-mortality diseases in the world.Numerous epidemiological studies have demonstrated that presence of COPD increases the risk of lung cancer.Habitual cigarette smoking frequently develops lung cancer as well as COPD,However the links between the two diseases should be more than smoking alone.The underlying mechanisms may include genetic predisposition,inflammation and cell injury,oxidative and noxious stress,extracellular matrix and proteinases,some of which might represent the targets for chemoprevention or chemotherapy.
