Contemporary spinal surgeons, whether orthopedic or neurosurgeons, are increasingly recognizing minimally invasive spine surgery (MISS) as a valuable option for managing advanced degenerative diseases. MISS techniques minimize blood loss and surgical site pain, while speeding recovery. Thus, the combination of MISS with adult spinal deformity was a natural choice. Currently, the techniques, technologies, and education of surgeons have finally reached a point where MISS deformity surgeries are becoming commonplace. Nevertheless, the field is young enough (and still evolving) that no comprehensive texts have addressed the unique challenges it poses for surgeons. This book fills that gap.
