The Department of Pediatric Orthopaedics of the Peking Union Orthopaedic Hospital boldly pioneered a new technology of multi-segment osteotomy limb lengthening May 7, 2015, seven months after surgery, half an hour to remove the stent and replace it with a protective cast, Gesang ** happily removed the lengthening stent! Lengthening 12 centimeters in only seven months, the team of Professor Li Jin of the Department of Pediatric Orthopaedics at the Union Orthopaedic Hospital broke a new record for limb lengthening speed! Li Jin, Professor Li Jin, Department of Orthopaedics, Peking Union Medical College Hospital, Wuhan, China The team of Professor Li Jin, Department of Pediatric Orthopaedics, Peking Union Medical College Hospital, has successfully carried out multi-segment osteotomy Ichthyosis brace lengthening for patients with severe inequality of the lower limbs and achieved surgical success. This is the first case in Hubei Province and the first case in central and western China. In October 2014, Kelsang**, a 5-year-old boy from the Tibetan border of the motherland, came to the Department of Pediatric Orthopedics of Wuhan Union Medical College Hospital under the guidance of his mother. Professor Li Jin, head of the Department of Pediatric Orthopedics of the Union Hospital, personally saw this special child. According to the child’s mother, because of the birth of unilateral below-knee developmental deformity, the two legs of Kelsang ** gradually occurred severe unequal length, the affected side has been shortened by 7 cm, and the foot turned outward. He had known that Professor Li Jin of the Department of Pediatric Orthopedics at Wuhan Union Hospital was very famous and one of the national authorities in pediatric orthopedics, and was experienced in pediatric limb orthopedics. Regarding limb inequality, the Department of Pediatric Orthopedics at the Union Hospital has had more than a decade of experience in treating it. With the guidance and support of Professors Du Jingyuan and Yang Shuhua, Prof. Li Jin has treated a large number of patients from 2 cm to 16 cm of shortening with success. Treatment methods include unilateral lengthening, semi-annular brace lengthening, annular brace lengthening cum Ichthyosis lengthening, etc. Epiphyseal osteotomy with various brace lengthening is generally used at 0.5-1.0 mm per day. For severe limb inequality, the treatment period is often months or even 1-2 years, which is very long. Professor Li Jin analyzed the child, who was already shortened by 7 centimeters at the age of 5, and had already started to affect the development of the pelvic spine, and was expected to develop into an adult shortened by at least 12 centimeters, which would take more than a year in a smooth case according to traditional methods. In order to shorten the treatment period, multi-segment osteotomy lengthening has been tried and succeeded in China and abroad. No one has yet performed it in the Midwest region of China. Limb lengthening itself is a very complicated operation, and the multi-segment lengthening design is even more complicated. After more than two hours of surgery, Professor Li successfully completed the multi-segment osteotomy and the installation of the Ichthyosis frame. The ultimate success of this surgery can shorten the treatment cycle of the patient by 1/3-1/2. It will greatly save the patient’s family’s energy and burden.
