When it comes to “hand surgery”, many people are unfamiliar with it, and even medical workers who know less about the division of labor in hospitals and have no contact with it are puzzled, what kind of department is it? Is it a general term for “surgical department”? People with a little knowledge often exclaim, “Now the division is really fine! Isn’t hand surgery also a part of orthopedics? How come there are doctors and departments specializing in the hand, I’ve never heard of them before! . The second hospital of Jilin University hand and foot and limb repair and reconstruction surgery center Tian Heng In fact, the hospital department refinement, specialization is part of the social division of labor, is also its inevitable result, medical subdivision specialization is conducive to focus time, energy, financial resources, sources of disease from basic research, clinical treatment, rehabilitation and health care, a comprehensive, systematic, scientific summary of the most safe, effective, economical, practical treatment program to protect The health of the people’s lives. “Hand surgery” is also based on the development of social handicraft industry, division of labor and medical professional refinement of such a general trend, especially at present, domestic agriculture is the main, machine-assisted agriculture, rapid development of industry, a large number of rural surplus labor into millions of factories, the use of hands and injuries will increase, but their safety awareness and Under the current social situation where the safety protection of machines and equipment is relatively poor, the emergency treatment and follow-up of hand trauma is still an important part of the work of hand surgeons. Because the foot and hand are very similar in anatomical structure and functional units, as the saying goes, “hand and foot love”, therefore, “hand surgery” is named “hand and foot surgery”. At this point, perhaps we all understand that the original “hand and foot surgery” is a department specializing in the treatment of hand and foot-related diseases. We realize that “hand and foot injuries, broken fingers, toes, fractures, broken tendons, broken blood vessels, numbness, stiff joints, pain is not good, bulging long swelling, infection, children more fingers, toes, or a few long together, longer than normal, short, long, long oblique or even missing” and so on these hand and foot of These hand and foot diseases should be treated in hand and foot surgery for more professional and better recovery! Indeed, this is the important work of hand and foot surgeons. However, the division of labor is not isolated and unique, but more in depth on the basis of solid comprehensive skills, and can be laterally linked with related disciplines to provide a broader, effective treatment options. Hand and foot surgery is no exception, because it once belonged to the orthopedic category, so hand and foot surgeons have conventional orthopedic treatment theory and skills; but at the same time, because of long-term engagement in finger and toe replantation, post-trauma repair, deformity correction and functional reconstruction, hand and foot surgeons have developed the unique skills of anastomosis of tiny blood vessels less than half a millimeter in diameter, fine repair of nerves and tendons, and to soft tissue, bone blood supply, tendons and nerves, They have a deep understanding of the blood supply of bone, tendon and nerve rehabilitation, fine minimally invasive operation, appearance after repair and reconstruction, etc., which enables them to “tear down the east wall and mend the west wall, and make a big difference, or even create something from nothing” in all parts of the body for soft tissues such as skin, muscles, tendons, ligaments, nerves and other bone and joint defects with ease. “Repair and reconstruction”. Therefore, hand and foot surgeons are more specialized in the treatment of trauma, bone disease, deformity, tumor, and infectious diseases of the hands and feet, as well as the replantation of severed tissues in other parts of the body (including scalp, nose, ears, lips, tongue, penis, etc.), the recanalization of small ducts (including lymphatic ducts, celiac ducts, ureters, vas deferens, fallopian tubes, arteriovenous fistulas for dialysis), the repair of combined skin, blood vessels, nerves, tendons, and bones of the extremities, and the repair of peripheral injuries and defects. We are also competent in the repair of damage and defects of the extremities, the treatment of muscle atrophy, movement disorders and sensory numbness caused by peripheral nerve damage and compression, hand and foot reconstruction, diabetic foot infection, vasculitis, burns and trauma scar release, and reconstructive surgery of the ear, nose, lip and tongue, jaw, larynx, breast, esophagus, penis and other tissues and organs. From this, we can see that hand and foot surgery is not only two treatment units divided by body parts from orthopedics, but also a core technology of “microtubular anastomosis, fine repair of nerve and tendon, and repair and reconstruction of tissue defects”, integrating traditional traumatology and orthopedics, absorbing plastic and cosmetic concepts and technologies, and pursuing the goal of limb function restoration and reconstruction and good appearance. It is an independent and inclusive medical subspecialty, and is positioned as “hand, foot and repair and reconstruction surgery” in name only. Jilin University Second Affiliated Hospital of Orthopedic Surgery Center for Hand, Foot and Reconstructive Surgery in the Second Affiliated Hospital of Jilin University in the pursuit of realistic progress, seize the opportunity, after the introduction of talent, resource integration, adhering to the “unified and balanced, complementary advantages” concept of the establishment of the orthopedic hospital, and in the orthopedic hospital under the tertiary disciplines – – “hand, foot and repair and reconstruction surgery”. -The Department of Hand, Foot and Reconstructive Surgery was established under the Department of Hand Surgery, Foot and Ankle Surgery and Reconstructive Surgery, of which Foot and Ankle Surgery is the first one in the province. At present, the department has 56 medical and nursing staffs, including 12 doctors, 4 professors, 5 attending doctors and 3 residents, and the famous hand surgery experts, Prof. Li Bingwan and Prof. Wang Yufa, are at the front line of clinical service for patients. It has 70 beds, with an annual outpatient and emergency volume of about 8,000, 2,300 inpatient cases and 3,000 surgeries. We routinely perform treatment of various hand and foot trauma, tendon, ligament, bone and joint diseases, peripheral nerve injury and compression, limb defect repair and reconstruction, deformity correction, bone and joint infection, diabetic foot, including replantation of difficult severed fingers such as pediatric broken fingers, tissue block severance, terminal finger body severance, decortication and rotational avulsion severance, finger reconstruction with tissue defects, toe transplantation, major car accidents, agricultural machinery strangulation, etc. The treatment of compound near amputation injuries, various island and free tissue flap repair techniques, functional reconstruction of birth palsy and peripheral nerve injuries, minimally invasive treatment of hand and foot bone and joint injuries, deformity correction, functional reconstruction, stem cell treatment of chronic refractory trauma such as osteoarthritis and diabetic foot, etc. have reached the leading position in the province and have specialized and standardized international level.
