In the early spring rain, I flew to Chongqing with my graduate student Zhang Hongan to Nanchong, Sichuan Province on March 27. After one and a half days of minimally invasive needle knife surgery, more than ten children with cerebral palsy had their deformities such as hip inversion, knee flexion and pointed foot corrected. In one case of stroke hemiplegia, the deformities such as shoulder inversion, elbow flexion, forearm rotation, and wrist and finger flexion were corrected immediately after surgery, and the limb deformities of other adult palsy patients also improved to different degrees. ”Ren’s Minimally Invasive Treatment Technique for Cerebral Palsy” was reproduced in Nanchong, Sichuan Province, with the assistance of anesthesiologists and nurses from the operating room of the local hospital and the trust of the patient’s family.
