Vertebroplasty and percutaneous kyphoplasty have played essential roles in the treatment of painful vertebral metastasis, although there are few reports with long survival that have evaluated the long-term efficacy, adjacent fractures and vertebral body (VB) re-collapse associated with these procedures. We aimed to evaluate the longterm efficacy and the complications associated with malignancy and changes in spinal biomechanics.
MATERIAL and METHODS: The retrospective study examined 32 patients with osteolytic VCF due to malignant infiltration of the vertebral body. A visual analogue scale, the EQ5 and radiological analysis (i.e., X-ray and CT scan) were used to assess back pain, quality of life and complications.
RESULTS: Statistically significant reductions in anterior and central vertebral body heights (6.2 mm-19.6 ± 4.2 mm- and 5.8 mm- 16.7 ± 7.8 mm-, respectively) that resulted in reductions of the regional Cobb angles exceeding 30% were observed. There was also a statistically significant improvement in quality of life. The average survival was longer than those reported in most published articles, and the average follow-up period was 30.9 months.
CONCLUSION: Anatomical restoration (i.e., cortical ring reduction with endplate rebalancing) is potentially beneficial for a wellselected group of patients with spine metastases and long life expectancies because this procedure avoids the complications typical of these types of treatments (e.g., leakage, adjacent fractures and re-collapse).
