Abstract

 Background: Vertebral compression fractures are increasingly common due to many causes: osteoporosis, spinal injury, vertebral body hemangioma, multiple myeloma,... of which osteoporosis is the most common cause. Balloon kyphoplasty is a method that brings many benefits to patients. Objectives: To evaluate clinical and paraclinical characteristics, clinical improvement and vertebral kyphosis angle index in patients with vertebral compression fractures treated with balloon kyphoplasty. Materials and methods: A prospective descriptive study was designed on 22 patients diagnosed with thoracolumbar vertebral compression fractures due to osteoporosis treated with balloon kyphoplasty at Can Tho University of Medicine and Pharmacy Hospital. Results: Mean age: 70.27±10.53 (45-90), mainly > 60 years old (90.9%). Femal/male: 6.35/1, 100% osteoporosis with T-score ≤ -2.5. 100% of patients experience pain relief on the first day after the produce. The average VAS score decreased significantly from 7.32±1.09 before surgery to 1.27±0.98 after 24 hours and 1.14±1.04 after a month. After a month, accroding to modified MacNab criteria, the excellent and good results were 21/22 patients (95.45%), moderate results were 1/22 patients (4.55%), no patient had poor results. The effectiveness in height restoration of vertebral body was from 67.63±11.03% pre-op to 81.82±6.33% post-op. The local kyphotic angle, and local Cobb angle improved after surgery were statistically significant and maintained after a month of follow-up. Conclusions: Balloon kyphoplasty is safe and minimally invasive proceduce that provides a good methods for pain relief in patients with vertebral body compression fracture caused by osteoporosis.
