Fifty-eight (30 females) patients with a mean age of 55 were treated in our institution with minimal invasive surgery techniques for osteoporotic, traumatic and neoplastic fractures of the thoraco-lumbar spine. All patients completed pre-operatively and post-operatively the VAS score (0-10, 10 being the worst state for pain) as well as the Oswestry low back pain disability questionnaire at 3, 12, 24 and 36 months intervals. Overall the VAS score was reduced from 7.8 points pre-operatively, to 2.1 points at the 36 month follow up. Oswestry disability score improved from a pre-operative severe disability to moderate disability at 3 months up to a minimum disability at 36 months. The minimally invasive surgical techniques can significantly improve clinical outcomes by preventing many of the drawbacks associated with open approaches whilst also allowing to associate other methods such as coblation, vertebroplasty, interbody fusion that can be complementary to vertebral fixation.
