43 patients, over the age of 65, with a single-level vertebral burst fracture were randomly assigned into 1 of 2 groups to compare the effectiveness of treatment with percutaneous kyphoplasty alone to percutaneous internal fixation with percutaneous kyphoplasty. Results of the study indicated that percutaneous internal fixation with percutaneous kyphoplasty offered superior outcomes in VAS pain and ODI improvements compared to percutaneous kyphoplasty. This results support the use of percutaneous internal fixation with percutaneous kyphoplasty in the treatment of elderly patient with thoracolumbar burst fractures as this treatment was able to maintain kyphosis angle correction, improve disability scores, and rapidly relieve lumbar back pain.
