The Relationship between Correction of Local Kyphosis and Overall Sagittal Alignment in Osteoporotic Vertebral Fracture Treated by Percutaneous Kyphoplasty
摘要
Abstract
Objective:To evaluate the relationship between correction of local kyphosis and overall sag-ittal alignment in thoracolumbar spinal osteoporotic vertebral fracture treated by percutaneous kyphoplasty. Methods:From Mar. 2013 to Sep. 2015, 70 patients with osteoporosis vertebral compression fracture treated by PKP were included in the study. Preoperative and postoperative radiographs were analyzed to quantify local and overall spinal sagittal alignment correction. The correlation of local and overall spinal sagittal alignment ( the C7/SFD ratio) correction was analyzed. Results: Measurements revealed that all the kyphoplastys re-duced kyphotic angle at the fractured vertebra by 6.72±1.92°;Single-level kyphoplasty reduced kyphotic an-gle at the fractured vertebra by 5.66±1.26°; Single-level kyphoplasty reduced thoracic kyphotic angle at the fractured vertebra by 5. 36 ± 1. 32°; Single-level kyphoplasty reduced lumbar kyphotic angle at the fractured vertebra by 5.36±1.32°. The C7/SFD ratio was reduced by 0.03±0.02 with all the kyphoplastys. Single-level kyphoplasty reduced the C7/SFD ratio by 0.02±0.01. Single-level kyphoplasty in thoracic fractures reduced the C7/SFD ratio by 0.02±0.01. Single-level kyphoplasty in lumbar fractures reduced the C7/SFD ratio by 0. 02 ±0.01. Except single-level lumbar fracture, the C7/SFD ratio was significantly correlated with local kyphot-ic angular reduction of fractured vertebra. Double-level kyphoplasty reduced the C7/SFD ratio by 0.04±0.02. Three-level kyphoplasty reduced the C7/SFD ratio by 0.06±0.03. The C7/SFD ratio was significantly correla-ted with local kyphotic angular reduction of fractured segments. Comparing single-level thoracic fracture with single-level lumbar fracture, local kyphotic angular reduction of fractured vertebra and the C7/SFD ratio have no sense of statistics. Conclusions:Better improvement was seen on the global sagittal spinal alignment with higher local kyphotic angular reduction after kyphoplasty. More fractured segments after kyphoplasty, higher local kyphotic angular reduction at the fractured vertebra and better improvement of the global sagittal spinal a-lignment.关键词
