Description:

The definitive practical reference on managing idiopathic scoliosis from world-renowned experts

Idiopathic Scoliosis: The Harms Study Group Treatment Guide, Second Edition, edited by Peter O. Newton, Amer F. Samdani, Harry L. Shufflebarger, Randal R. Betz, and Jürgen Harms and written by an impressive group of experts reflects treatment advances made in the last decade. Greater understanding of the etiology and improved 3D anatomy has resulted in significant strides in clinical management of scoliosis. This richly illustrated book presents all facets of evaluation and treatment of abnormal curvature of the spine, supported by a solid foundation of evidence-based data culled from the prestigious Harms Study Group.

Divided into four sections and 31 chapters, this one-stop reference encompasses the full spectrum of surgical and nonoperative interventions—from early treatments to modern novel growth modulation techniques. In this second edition, each chapter has been updated and several new ones have been added, reflecting current literature, practice, and expert perspective. Throughout the book, masters share clinical pearls and firsthand knowledge on managing diverse types of adolescent idiopathic spinal deformity, with the common goal of improved patient outcomes.


Key Highlights

Innovative topics include teamwork and safety in spine surgery, halo traction for large curves, anterior growth modulation, intraoperative neuromonitoring, and kyphosis restoration in scoliosis surgery

Surgical chapters follow a consistent layout, encompassing rationales, techniques, and outcomes

Postoperative chapters feature discussion of long-term clinical and radiographic outcomes, infections, complications, and rapid post-op recovery

A wealth of illustrations enhance the reader's knowledge of specific techniques

This comprehensive textbook is essential reading for orthopaedic and neurosurgical residents, fellows, and researchers. Young spine surgeons embarking on their careers and senior surgeons who wish to remain up-to-date on new techniques for treating adolescent idiopathic scoliosis will also benefit from this illuminating resource.
