Objective To investigate the characteristics and corrective strategies of various limb deformities treated by QIN Sihe orthopaedic team in the past 40 years, so as to provide a large sample for understanding the causes, types, and treatment methods of limb deformity and disability in China.Methods A clinical data of 35 075 cases who were treated by QIN Sihe orthopaedic team between May 1978 and December 2018 was summarized. The age, gender, deformity characteristics, etiological and pathological composition, regional distribution, and surgical methods of the patients were analyzed.Results There were 20 458 males (58.33%) and 14 617 females (41.67%). The age ranged from 1 to 82 years (mean, 20.5 years). The majority people (19 363 cases, 55.20%) were 11-25 years old. Of which, 33 259 cases (94.82%) were operated on lower extremity. The geographical distribution of patients covered 33 regions in China and 12 foreign countries. There were 202 etiologies involved neurological, heredity, metabolism, traumatic sequelae, congenital, vascular, lymphoid, skin, endocrine, iatrogenic, and so on. The disease covered all subsubjects of orthopaedics. The top six deformities secondary to poliomyelitis sequelae, cerebral palsy, traumatic sequelae, spondylolysis sequelae, genu varum and genu valgum, and congenital talipes equinovarus. There were 280 kinds of surgical methods, the majority of which were Achilles tendon lengthening, supracondylar osteotomy, subtalar joint arthrodesis, tibiofibular osteotomy, metatarsal aponeurosis, and Achilles tendon replacement of peroneal longus muscle, etc. Orthopaedic surgery combined with external fixation were applied in 8 702 cases, including Ilizarov fixator in 3 696 cases and Hybrid fixator in 5 006 cases.Conclusion QIN Sihe orthopaedic database with 40 years is the largest one of limb deformity and disability in China. It reflects the etiology, type, population characteristics, surgical methods and strategy of limb disability and deformity which can be treated by orthopaedic surgery. The data needs to be further excavated and deeply studied in future because of its important academic value and historical significance.
