A cost-minimization analysis in minimally invasive spine surgery using a national cost scale method.

Introduction: The last decade has seen the emergence of minimally invasive spine surgery. However, there is still no consensus on whether percutaneous osteosynthesis (PO) or open surgery (OS) is more cost-effective in treatment of traumatic fractures and degenerative lesions. The objective of this study is to compare the clinical results and hospitalization costs of OS and PO for degenerative lesions and thoraco-lumbar fractures.
