Meeting held July 2012 in Poznan, Poland.

It is over 70 years since two orthopedic surgeons invented the Milwaukee brace for the treatment of children with scoliosis. Since then, clinicians and researchers have been inspired to design ever more effective braces to correct 3-D spinal deformities. This book presents papers from the bi-annual meeting of the International Research Society of Spinal Deformities (IRSSD), held as a virtual event on 22 and 23 January 2021. The IRSSD concentrates on research into spinal deformity with clinical applications. In addition to 3D assessment of the spine, researchers also explore spinal biomechanics, etiopathogenesis, and innovative conservative and surgical therapies with the goal of integrating science with clinical care to improve patient care. The 2021 meeting was originally scheduled to take place in Milwaukee, Wisconsin, USA, but was instead held in a virtual format due to the Covid 19 pandemic. Despite this change, the meeting still allowed valuable interaction and open discussion among practitioners from around the world, and keynote speakers and authors contributed the 44 short papers and 47 abstracts included here. The papers are grouped under 17 chapter headings, and cover a wide range of topics, including biologic and biomechanical benchmarks, clinical evaluation, conservative treatments and surgical approaches. Diagnostic assessments and non-surgical treatments of EOS are also emphasized and elucidated. The book will be of interest to all those whose work is related to the treatment and care of patients with spinal deformities.

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.

Spinal disorders are among the most common medical conditions with significant impact on health related quality of life, use of health care resources and socio-economic costs. This is an easily readable teaching tool focusing on fundamentals and basic principles and provides a homogeneous syllabus with a consistent didactic strategy. The chosen didactic concept highlights and repeats core messages throughout the chapters. This textbook, with its appealing layout, will inspire and stimulate the reader for the study of spinal disorders.

This book provides comprehensive coverage of current topics in idiopathic scoliosis (IS). A three-dimensional deformity of the spine, the condition is characterized by lateral curvature combined with vertebral rotation. The primary lesion, however, lies in the median sagittal plane, taking the form of a lordosis. Although the clinical manifestations of scoliosis have been well documented, its cause and pathogenesis have not yet been determined. Research into what causes IS has focused on the structural elements of the spine, spinal musculature, collagenous structures, the endocrine system, the central nervous system, and genetics. Results of these studies have brought about a new perception of IS epiphenomena, but the main cause of IS remains unknown. Recently, several investigators have produced new hypotheses regarding the cause of IS using the developing techniques of genetics, biochemistry, and neurology. This book is a review of the various causative factors thus far proposed for IS and an introduction to the directions in which research is heading to determine the primary cause of IS.

Three-dimensional scoliosis therapy has for decades played an established role in the conservative management of mild and even of severe scoliosis. As well as describing every aspect of the pathologically curved, deformed spine, this textbook incorporates an extensive programme of exercises that can be tailored specifically to the needs of the individual patient. As outlined in Three-Dimensional Scoliosis Therapy: The Schroth Breathing Orthopaedic System, correction of the spinal deformity is based on a special breathing technique and active muscle stretching, as well as on elongation, detorsion and reduction of lordosis. The provision of psychological support for the patient is also emphasised as a key element. Christa Lehnert-Schroth born 1924 in Meissen She worked as a physiotherapist for about 50 years with scoliosis patients and further developed her mother's breathing orthopaedic technique with great success. Between 1961 and 1995 Christa Lehnert-Schroth - always surrounded by physicians - was director of the private Katharina-Schroth-Klinik in Bad Sobernheim/Germany. In many lectures, articles, seminars and films for physiotherapists and medical doctors in addition to recorded discs for patient's training at home she illustrated her mother's special method for scoliosis assuring well being of many patients and in honor her mother's legacy.
