Professor Yu Guangrong has made outstanding achievements in the clinical and basic research of foot and ankle surgery, and has rich clinical experience in the diagnosis and treatment of difficult and complicated diseases in foot and ankle surgery. The plastic titanium plate designed and developed by ourselves has been used to treat various types of calcaneal fractures, which has achieved remarkable clinical results, won two national new practical patents, and has been widely used in many tertiary and secondary hospitals across the country. In clinical microsurgical research, many operations have been carried out, such as replantation of severed limbs, toe transplantation to reconstruct thumb, various skin flaps and musculocutaneous flaps, various bone flaps and bone flaps, free jejunum transplantation to reconstruct esophagus, omentum transplantation to treat ischemic diseases of limbs, vascularized nerve transplantation and composite tissue transplantation to repair composite tissue defects of limbs, etc. It is the first time in the world to report the reconstruction of the whole radius with free fibula transplantation and the repair of long peripheral nerve defects with arterialized lateral forearm cutaneous nerve transplantation. For the second dorsal metacarpal artery flap and composite tissue flap, 12 transplantation methods were studied and successfully applied to clinical promotion, and won the second prize of scientific and technological achievements of the Ministry of Railways 1999. We can actively promote the theory and principle of AO in the study of clinical bone and joint injuries, and promote the international advanced internal fixation materials and technologies earlier in China, and strive to improve the treatment level of bone and joint injuries in China, such as PFNa, LCP, locking nails and reverse locking nails. Surgical treatment of different types of pelvic fractures and acetabular fractures: minimally invasive techniques are used to treat intra-articular injuries and fractures. In 2002, he won the third prize of Shanghai scientific and technological achievements, the third prize of Shanghai clinical medical achievements in 2003, the third prize of Shanghai medical achievements in 2008 and the second prize of Shanghai scientific and technological progress. In the clinical diagnosis and treatment of bone tumors, limb salvage surgery is actively carried out to reconstruct various defects of limbs and joints through methods such as inactivated replantation of tumor bones, allogenic bone transplantation, vascularized fibula transplantation and artificial prosthesis implantation. Make the five-year survival rate of osteosarcoma patients in tongji hospital reach about 50%; The excellent and good rate of limb salvage surgery is over 78%. Active resection and reconstruction of primary and secondary malignant tumors of sacrum and pelvis have achieved good clinical results. Excision of tumor around acetabulum and reconstruction of free fibula transplantation were invited to give a special speech at the international conference on bone tumors.
