This book will guide readers on the choice of operative therapy for various degenerative spinal conditions. Although there are numerous spinal texts, this book is one of only a few dedicated to improving the quality of life of patients with degenerative scoliosis. The book consists of three main sections. First, an overview of lumbar degenerative scoliosis anatomy and pathoetiology, imaging and radiographic techniques, the importance of spinal balance, conservative management, and the differences between de novo lumbar degenerative scoliosis and adult idiopathic scoliosis. The second portion gives an overview of the indications for treatment and surgical planning. The third and final section discusses the available surgical techniques with commentary on the experience of experts in the field. These last two sections are presented in a unique format and include: case presentation with images and figures, surgical principles, boxed areas with key concepts, and a conclusion that summarizes potential complications and tips to optimize management.
