Sun's bone-setting technique originated in Xinshao County, Hunan Province, the core circle of the ancient "Meishan Culture". It is the product of the organic integration of the mysterious Hunan folk traditional bone-setting technique and modern bone-setting technique. It has extremely high scientific research value for studying Hunan culture, revealing the scientific components of Meishan medicine, and enriching my country's traditional bone-setting medicine. In 2008, Sun's bone-setting technique was included in the second batch of intangible cultural heritage list of Hunan Province. Bone-setting techniques Sun's bone-setting technique attaches importance to the use of traditional techniques. The main techniques include 11 bone-setting techniques such as "pulling and stretching, lifting and pressing, and touching and pressing"; 8 upper joint techniques such as "pulling, pushing and pulling, shaking and unlocking, and rotating and prying to reset"; 9 tendon-regulating techniques such as "smoothing, pinching and elasticity, flexion and extension, and pulling and stretching". Pharmaceutical skills formula: It is made of a combination of Radix Dipsaci, Sichuan pepper, cloves, Rhizoma Chuanxiong, Angelica sinensis, camphor, Acanthopanax acanthopanacis, Shengnanhao, Radix Angelicae Dahuricae, and 1. Preparation: Grind into fine powder and mix into ointment. Sun's bone setting technique mainly uses splint fixation in external fixation. For the production of splints and external fixation devices, it emphasizes "momentum" (conform to the anatomical structure and conducive to functional training) and "toughness" (toughness and firm fixation of fractures). On the basis of traditional splint fixation, the design of splints has been improved. Heel support splints for calf fractures, bracket splints for humeral shaft fractures, system splints for forearm fractures, and hook external fixation brackets for femoral trochanteric fractures have been invented; on the basis of the ""-shaped bandage, shoulder-arm straps have been invented to improve the fixation method of clavicle fractures; for unstable long bone fractures, percutaneous puncture combined with splint external fixation is advocated. The special prescriptions of Sun's bone-setting technique include: "Qiwei Jinhuang Powder", "Prescription No. 1-3 for Upper Limb Injury", "Prescription No. 1-3 for Lower Limb Injury", "Prescription Series for Chest Injury", "Prescription Series for Head Injury", "Prescription Series for Spinal Injury", "Broken Paste", "Analgesic Powder", "Blood Activating Powder", "Analgesic Capsules", "Bone Setting Capsules", "Broken Capsules", "Bone Strengthening Capsules" and more than 40 other ancestral prescriptions and special preparations with significant efficacy. The founder of the inheritance of Sun's bone-setting technique is Sun Xiaokun from Xinshao County. In the early years of the Republic of China, Sun Xiaokun, a bone-setting doctor who was already well-known in Meishan medical skills, went out to travel and seek a teacher. He studied under the Shaolin monk Qi Baozi, learned martial arts and medicine, and mastered the unique Shaolin skills of treating bone injuries. After returning home after completing his studies, Sun Xiaokun boldly integrated the Shaolin bone-setting treatment skills with the local traditional Meishan bone-setting medical skills, diligently studied the mysterious bone-setting skills, practiced medicine, and saved lives, becoming a generation of bone-setting doctors with a reputation in the medical field in central Hunan. After the founding of New China, Sun Xiaokun responded to the government's call and opened a joint orthopedic clinic in Xinshao County. It had 20 inpatient beds and became the first orthopedic clinic of a certain scale in Shaoyang at that time. In 1960, Sun Xiaokun, a famous doctor of his generation, passed away at the age of 52. The second-generation inheritor of Sun's bone-setting technique was Sun Guangsheng, his nephew. He studied medicine with his uncle Sun Xiaokun since he was a child and learned the true skills of bone-setting and healing. In order to carry forward the family-learned Sun's bone-setting medical skills, Sun Guangsheng successively studied in Hunan Provincial Health Cadre School, Hunan University of Traditional Chinese Medicine, Guiyang University of Traditional Chinese Medicine, and Tianjin Medical College. While actively learning modern medical science, he integrated Chinese and Western medicine, learned from many others, and always adhered to the traditional Sun's bone-setting medical skills. He proposed the bone-setting and healing theory of "equal emphasis on form and spirit, overall adjustment, tendon regulation and bone-setting, and stage-position differentiation and treatment". In 1974, Sun Guangsheng boldly introduced modern bone injury techniques such as surgical open reduction and internal fixation to treat severely displaced intra-articular fractures, open fractures, and old fractures in the Sun's Joint Clinic. In 1975, he founded the Sun's Orthopedics Specialty in Xinshao County Hospital of Traditional Chinese Medicine. In 1978, the Xinshao County Government officially appointed Sun Guangsheng as the director of the County Hospital of Traditional Chinese Medicine. In 1996, Xinshao Hospital of Traditional Chinese Medicine was officially named "Shaoyang Orthopedics Hospital" by the Shaoyang Municipal People's Government, which enabled the rapid development of Sun's Orthopedics. In 1998, Liao Huaizhang, the third-generation inheritor of Sun's bone-setting technique, became the director of the Orthopedic Hospital. Liao Huaizhang is a doctor of traditional Chinese medicine and a proud disciple of Sun Guangsheng. He has always been the leader of the research discipline of Sun's bone-setting technique. With the support of Sun Guangsheng, he comprehensively and systematically summarized and sorted out Sun's bone-setting technique from the perspectives of bone injury theory, clinical treatment, and prescription compatibility. He used the traditional bone injury therapy of Sun's bone-setting technique to carry out a number of difficult orthopedic treatment surgeries and treatment research, and achieved dozens of national and provincial scientific research results. In 2003, Shaoyang Orthopedic Hospital was designated by the Hunan Provincial Government as a provincial key specialized hospital for traditional Chinese medicine bone injury treatment.
