INTRODUCTION: Very severe osteoporotic vertebral compression fractures (vsOVCFs), which are vertebral bodies collapsed to less than one-third of their original height, are considered as a relative contraindication to vertebral augmentation techniques. The purpose of our study was to evaluate the safety and efficacy of balloon kyphoplasty in treating vsOVCFs. METHODS: Between January 2005 and December 2010, 26 patients (23 women, 3 men) with 27 very severe vertebral fracture bodies underwent balloon kyphoplasty. The vertebral height, local kyphotic angle, visual analogue scale (VAS) and Oswestry Disability Index (ODI) values were assessed before the operation, 1 day after the operation and at the final follow-up. Post-operative computed tomography scans were used to detect cement leakage. RESULTS: Asymptomatic cement leakage occurred in 7 of 27 treated vertebral fractures (25.9 %). Three patients (11.5 %) were proved to have subsequent vertebral compression fractures (VCFs). There were significant improvements in the vertebral height and kyphotic angle after surgery (p < 0.01). A total of 22 patients (84.6 %) exhibited partial or complete pain relief, and the mean VAS and ODI scores decreased significantly from pre-operation to post-operation (p < 0.01). CONCLUSION: Kyphoplasty is a safe and effective procedure for the treatment of vsOVCFs. It achieved significant vertebral height restoration and kyphotic angle reduction. Relief of pain and improvement in function were also observed in most patients.
