Spinal osteotomy techniques have been dramatically applied as a standard method for severe and rigid spinal deformity. Although clinical results indicate that patients who undergo osteotomy procedures typically experience well deformity correction and ameliorate the clinical appearance, aggressive peri-operative risks and follow-up complications are not rare. More meticulous and standard indication selection, osteotomy plan design and complication prevention strategy and outcome evaluation are critically needed for surgeon majored in spine deformity. The book Spinal Osteotomy is divided into sections that focus on principles of spinal osteotomy, technical and case illustration and outcomes and complications as well as computer navigation and other latest techniques. Each section is heavily illustrated and clearly written for ease of understanding. Orthopedic surgeons, neurosurgeon residents and fellows who want to focus on spinal deformity correction will find this instructive and invaluable.
