Thanks to his many-year explorations and practice, Prof. LI Ming, from the Changhai Hospital affiliated to the No. 2 Military Medical School, has achieved progresses in treating and studying spinal column deformation. LI and his team harvested a number of innovative findings, including treating advanced cases of spinal column side-protruding, and root nailing technique. The operation he performed on patients of advanced side-protruding spinal column produced noticeable therapeutic effects, avoided a second operation that would be required under the previous operation procedure, and saved the patients their medical bills. LI and his team have treated over 100 advanced patients with a protruding side arch of 80 degrees or above, using the same technique, and achieved satisfactory results.
