ABSTRACT
BACKGROUND: It is stil controversial about whether percutaneous vertebroplasty can be as an option for treatment of non-osteoporotic single-segmental vertebral traumatic compression fractures. OBJECTIVE: To observe the effect of percutaneous vertebroplasty in repair of non-osteoporotic single-segmental vertebral traumatic compression fractures. METHODS: Total y 20 patients who underwent percutaneous vertebroplasty in repair of non-osteoporotic single-segmental vertebral traumatic compression fractures between March 2010 and January 2013 were col ected. The variation of visual analog scale scores and the Oswestry disability index scores of patients was observed before and after the repair. RESULTS AND CONCLUSION: (1) The visual analog scale scores and the Oswestry disability index scores of patients were significantly reduced after repair compared with those before repair, moreover, the visual analog scale scores and the Oswestry disability index scores of patients at the 3, 6, 12 and 18 months after repair were similar. (2) Al patients had no adverse effects and complications. (3) These results suggest that percutaneous vertebroplasty in repair of non-osteoporotic single-segmental vertebral traumatic compression fractures quickly relieves back pain and improves the actives of thoracolumbar segments.
ABSTRACT
BACKGROUND:Studies have shown that percutaneous pedicle screw internal fixation in repair of single segment of thoracolumbar fracture can overcome quadrilateral effect, get better biomechanical properties, meanwhile, it also can provide three-point fixation, reduce suspension effect, and reduce the formation of kyphosis. OBJECTIVE: To investigate the clinical efficacy and incidence of complications of the percutaneous pedicle screw internal fixation for treatment of single segment thoracolumbar fractures. METHODS:Totaly 36 patients with single segment thoracolumbar fractures treated by percutaneous pedicle screw internal fixation were enroled. A total of 36 vertebral bodies were treated: T11=5, T12=8, L1=17, L2=6. The visual analog scale scores before treatment and at 3, 6 and 12 months after treatment, the Oswestry disability indexes before treatment, at the first week and at the 12th month after treatment, the Cobb angle before treatment, the first day and at the 12th month after treatment were compared and observed. The incidence of complications was recorded. RESULTS AND CONCLUSION:The visual analog scale scores at 3, 6 and 12 months after treatment was significantly lower than those before treatment (P < 0.001). The Oswestry disability indexes before treatment, at the first week and at the 12th month after treatment were significantly lower those that before treatment (P < 0.001).The Cobb angle before treatment, at the first day and at the 12th month after treatment was significantly smaler than that before treatment (P < 0.001). Only three (8%) patients had complications, including pedicle screw penetrating pedicle into the spinal canal, pedicle screws loosing and the infection in puncture site. These results suggest that percutaneous pedicle screw internal fixation for treatment of single segment thoracolumbar fractures can correct kyphosis, improve the thoracolumbar motion, quickly relieve patient’s back pain, and the incidence of complications is low.
