[Clinical application of the combination of postural reduction and kyphoplasty for traumatic thoracolumbar spine fractures].

ABSTRACT

OBJECTIVE: To determine the efficacy and feasibility of the combination of postural reduction and percutaneous kyphoplasty for traumatic thoracolumbar spine fractures. METHODS: Thirty-seven patients with single level traumatic thoracolumbar spine fractures were included in this study. There are 28 males and 9 females, with an average age of 48 years (range 24 to 79 years). Patients were treated with postural reduction and then percutaneous vertebroplasty with Calcium Phosphate Cement (CPC) were performed on the fractured vertebra. The results were quantitatively evaluated, according to the concept of estimated vertebral height loss and kyphotic angle of the vertebral fractures by preoperative and postoperative plain standing lateral radiographs. Visual analog scale (VAS) and the fracture vertebra shape changes were recorded. RESULTS: Patients were followed up for 9 to 24 months (average 13 months), pain was significantly relieved compared with the preoperative, VAS was reduced averagely from 7.6 +/- 2.5 to 1.8 +/- 1.5, the anterior and middle vertebral height was restored and kyphotic angle was corrected. During the period of follow up, outcomes were satisfactory, without notable correction loss. CONCLUSION: If the indications are correctly handled, the combination of postural reduction and percutaneous kyphoplasty for the treatment of traumatic thoracolumbar spine fractures can provide significant pain relieve and restore the vertebral height and kyphotic angle.
