Specific operative and nonoperative techniques and their results are stressed. The book is extensively illustrated with drawings, most of which were made for this book, microscopy photos, and serial radiographs. The reader learns of pediatric orthopedic deformity in relation to normal and abnormal developmental biology, the worsening of untreated disease with growth, and the diagnostic and treatment interventions required based on the stage of progression.* Treatments are correlated with the pathologic state of the disorder* Discusses disorders from earliest onset to the final state showing how the altered biology leads to progressively greater clinical deformity* Initial chapter focuses on development bone biology stressing a broad based approach involving histologic, gene and molecular, and biomechanical features* Subsequent chapters discuss the pathogenesis of the various deformities, natural history, radiographic and imaging findings and orthopaedic and surgical management
