Definition, Scope, and History of Orthopedic Surgery - Orthopedic surgery is a branch of surgery that focuses on conditions involving the musculoskeletal system. - Orthopedic surgeons use both surgical and nonsurgical methods to treat musculoskeletal trauma, spine diseases, sports injuries, degenerative diseases, infections, tumors, and congenital disorders. - The discipline was initially developed with attention to children, but it now covers spinal and bone deformities in all stages of life. - Orthopedic surgeons work in hospitals and clinics. - The education required to become an orthopedic surgeon includes a Bachelor of Medicine, Bachelor of Surgery (M.B.B.S.), Bachelor of Medicine, Bachelor of Surgery (MBChB), Doctor of Medicine (M.D.), or Doctor of Osteopathic medicine (D.O.). - The spelling of orthopedics can vary, with some using the spelling 'orthopaedics' and others using 'orthopedics.' - Orthopedic surgery has its roots in the Middle Ages, where bandages soaked in horse's blood were used as splints. - The term 'orthopedics' was coined by Nicolas Andry in 1741 in the first textbook on the subject. - Jean-André Venel established the first orthopedic institute in 1780, dedicated to treating children's skeletal deformities. - Advances in surgical technique during the 18th century expanded treatment options. - Antonius Mathijsen invented the plaster of Paris cast in 1851, revolutionizing orthopedic treatment. - Hugh Owen Thomas and Robert Jones played significant roles in the development of modern orthopedic surgery. - Gerhard Küntscher pioneered the use of intramedullary rods to treat fractures. - Sir John Charnley developed the modern total hip replacement in the 1960s.

Advancements in Orthopedic Surgery - The Charnley low-friction arthroplasty and its derivative designs were the most-used hip replacement systems for over two decades. - The Exeter hip replacement system, with a slightly different stem geometry, was developed around the same time. - Continuous improvements have been made in the design and technique of hip implants. - Intramedullary fixation without opening up the fracture became popular in the late 1970s. - Orthopedic surgery continues to advance with new technologies, techniques, and materials.

Training and Specialization in Orthopedic Surgery - Completion of four years of undergraduate education and four years of medical school. - Residency training in orthopedic surgery, typically lasting five years. - Selection for residency training is highly competitive. - Fellowship training in orthopedic sub-specialties, lasting one to two years. - Board certification by the American Board of Medical Specialties or the American Osteopathic Association Bureau of Osteopathic Specialists.

Specific Procedures in Orthopedic Surgery - Arthroscopy, pioneered by Masaki Watanabe, allows for faster recovery compared to open surgery. - Arthroplasty is the replacement, remodeling, or realignment of the articular surface of a joint. - Knee replacements developed by McIntosh, Gunston, Marmor, Insall, Buechel, and Pappas. - Joint replacements available for other joints such as hip, shoulder, elbow, wrist, ankle, spine, and fingers. - Surface replacement of joints, particularly the hip, is becoming more popular among younger and active patients.

Future of Orthopedic Surgery and Epidemiology - Focus on decreasing prescription of opioids while providing adequate pain control. - Continued research and development to make surgery less invasive and improve implant durability. - Collaboration with other medical specialties for comprehensive patient care. - Emphasis on evidence-based practices and outcomes research. - Integration of technology and innovation in orthopedic surgical techniques and procedures. - Prevalence of musculoskeletal procedures in the U.S increased from 17.9% to 24.2% between 2001 and 2016. - Spine and joint procedures were common in all age groups except infants in a 2012 study. - Spinal fusion, laminectomy, knee arthroplasty, and hip replacement were among the top procedures for various age groups.
