RESUMO
Objective Clinical investigation of treatment of osteoporotic vertebral compression fractures by unilateral kyphoplasty.Methods After Surgical intervention of sixteen vertebral compression fractures by unilateral kyphoplasty,then investigate the changes of height and Cobb angle of vertebral bodies.Results All surgical procedures were finished safely.The mean height of the anterior and media vertebral bodies was 1.8?0.3cm,1.4?0.4cm preoperatively and 2.2?0.4cm、2.3?0.3cm postoperatively;the Cobb angle was decreased from 28.4??10.2? preoperatively to 19.2??4.5? postoperatively.The mean absolute value of the difference in height between right and left side of the vertebral bodies was 0.1cm in this group.Conclusions The kyphosis is improved and the operative time is reduced by unilateral kyphoplasty.Though this result is satisfied,more clinical studies are needed to be done for authenticating the effect of unilateral kyphoplasty on the treatment of vertebral compression fractures in the future.
