چکیده
This study aimed to explore the clinical effects of percutaneous kyphoplasty combined with pedicle screw fixation on aged osteoporotic thoracolumbar burst fracture. 160 patients with aged osteoporotic thoracolumbar burst fracture treated at our hospital during January 2012 and January 2015 were enrolled. According to the digital meter method, they were randomly divided into two groups, the observational group underwent the therapy of percutaneous kyphoplasty combined with pedicle screw fixation and the control group received the treatment of pedicle screw fixation. The visual analogue scale (VAS), JOA score, Oswestry disability index (ODI) score, anterior flange height and vertebral body Cobb angle were recorded in follow-up visit at different time periods before and after operation. All patients underwent follow-up examinations for 12-24 months at home or at outpatient by therapists, averaged 15.92±2.04 months. The VAS scores at 1, 3 and 7d after operation were significantly lower in observational group than that of control group. The Oswestry disability index (ODI) scores at 1 week, 1 month and 2 months after operation were significantly lower in observational group than that of control group. The JOA scores at 5, 10 and 20d after operation were significantly higher in observational group than that of control group. The anterior flange heightat 2 and 6 months after operation were significantly more in observational group than that of control group. The vertebral body Cobb angle at 3 and 6 months after operation were significantly lower in observational group than that of control group, with a statistically significant difference (P<0.05). In conclusion, percutaneous kyphoplasty combined with pedicle screw fixation therapy on aged osteoporotic thoracolumbar burst fracture are markedly effective to decreases the pain after operation and reduce the bedridden time. In addition, the thoracolumbar stability is stronger, and the anterior flange height, vertebral body Cobb angle were less changed after treatment. Thus, this method is suitable to be widely used in future.

BACKGROUND Percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP) could give rise to excellent outcomes and significant improvements in pain, analgesic requirements, function, cost, and incidence of serious complications for thoracolumbar osteoporotic vertebral compression fractures (VCFs). But some studies showed the recurrent fracture of a previously operated vertebra or adjacen...

BACKGROUND During the last few years, an increasing number of unstable thoracolumbar fractures, especially in elderly patients, has been treated by dorsal instrumentation combined with a balloon kyphoplasty. This combination provides additional stabilization to the anterior spinal column without any need for a second ventral approach. CASE PRESENTATION We report the case of a 97-year-old male...
متن کاملBiomechanical Analysis of Pedicle Screw Fixation for Thoracolumbar Burst Fractures.
Treatment of unstable thoracolumbar burst fractures remains controversial. Long-segment pedicle screw constructs may be stiffer and impart greater forces on adjacent segments compared with short-segment constructs, which may affect clinical performance and long-term out come. The purpose of this study was to biomechanically evaluate long-segment posterior pedicle screw fixation (LSPF) vs short-...

The indications for operative treatment and type of stabilization procedures for the treatment of thoracolumbar burst fracture remain controversial. As surgical reconstruction for the thoracolumbar burst fracture, both long-segment pedicle screw fixation and short-segment pedicle screw fixation including fractured vertebral body have been used widely. The present study evaluated the efficacy of...
