Congenital, hereditary, metabolic, traumatic, infectious and other diseases can all lead to children's motor system diseases or secondary bone and joint deformities, especially once children's lower limb deformities occur, with the growth of age and bone development, the role of abnormal load-bearing stress will appear complex lesions, increasing the difficulty of treatment. The main purpose of writing this book is how to realize the early diagnosis and treatment of pediatric orthopedic diseases, how to adopt the theory and technology of modern orthopedic surgery, and how to treat pediatric orthopedic diseases through the concept of minimally invasive and minimally invasive technology in clinical work. The book is divided into 14 chapters and more than 800 drawings. In order to save readers' time, the text should be as concise as possible, and the writing form should not be the same, so as to avoid generalizing.

Traumatic fracture of children has been described in detail in many orthopedic works, and there are also many monographs on the correction of spinal deformity of children, which need not be repeated. Therefore, this book focuses on the diagnosis and surgical treatment of bone and joint deformities of children's limbs, especially lower limbs. Yili Sarow's biological theory of "minimally invasive traction tissue regeneration", combined annular external fixator and standard operating technology have been popularized and applied all over the world, which has changed the concept and treatment method of orthopedic surgery. In recent years, new progress has been made in basic research, instrument innovation and clinical application. It can satisfactorily correct all kinds of complex limb deformities, repair disabled limbs, and rebuild the shape and function of limbs without serious surgical complications. Therefore, modern orthopedics has entered the era of tissue repair and reconstruction dominated by external fixation technology (body plastic engineering). This book introduces the external fixation technology in detail, especially the basic theory and technology of "stretch tissue regeneration" newly researched and applied in clinic.

Limb deformity caused by cerebral palsy is becoming more and more prominent in pediatric orthopedic surgery. In recent years, orthopedic and neurosurgery have also made more progress in the surgical treatment of cerebral palsy, but there are few related monographs and documents, so this book is introduced as the key content.

This book is suitable for medical and health workers, medical college students and graduate students, especially for clinical orthopedics, pediatric surgery, plastic surgery and neurosurgeons.
