'''Orthopedic surgery''' or '''orthopedics''' (also spelled '''orthopaedics''') is the branch of [[surgery]] concerned with [[Acute (medical)|acute]], [[Chronic (medicine)|chronic]], [[Physical trauma|trauma]]tic, overuse [[injury|injuries]] and other disorders of the [[musculoskeletal system]]. Orthopedic surgeons address most musculoskeletal ailments including [[arthritis]], [[Physical trauma|trauma]] and [[congenital]] deformities using both surgical and non-surgical means. Nicholas Andry coined the word "orthopaedics", derived from [[Greek language|Greek]] [[word]]s for ''orthos'' ("correct", "straight") and ''paideia'' ("rearing" (usually of child)), in 1741, when at the age of 81 he published ''Orthopaedia: or the Art of Correcting and Preventing Deformities in Children''.
In the US the spelling ''orthopedics'' is standard{{Fact|date=February 2007}}, although the majority of university and residency programs{{Fact|date=February 2007}}, and even the [http://www.aaos.org/ AAOS], still use Andry's spelling. Elsewhere, usage is not uniform; in Canada, both spellings are common; ''orthopaedics'' usually prevails in the rest of the Commonwealth, especially in Britain.
== Training ==
In the United States and Canada, orthopedic surgeons are [[physicians]] who have completed applied training in orthopedic surgery after the completion of medical school and attainment of the conventional ([[Doctor of Medicine|MD, MBBS, MBChB, etc]]) or [[Osteopathic medicine in the United States|osteopathic]] ([[Doctor of Osteopathic Medicine|DO]]) degree. According to the latest Occupational Outlook Handbook (2006–2007) published by the US Department of Labor, between 3–4% of all practicing physicians are orthopedic surgeons.
Orthopedic surgeons (also known as orthopedists or orthopods) complete a minimum of 10 years of [[postsecondary education]] and clinical training. In the majority of cases this training includes obtaining an [[undergraduate education|undergraduate degree]] (a few [[medical school]]s will however admit students with as little as two years of previous undergraduate education), either an MD [[Doctor of Medicine|MBBS, MBChB, etc]]) or [[Osteopathic medicine in the United States|osteopathic]] ([[Doctor of Osteopathic Medicine|DO]]) degree, and then completing a five-year [[Residency (medicine)|residency]] in orthopedic surgery. The five-year [[Residency (medicine)|residency]] consists of one year of general surgery training followed by four years of training in orthopedic surgery.
After completion of specialty [[Residency (medicine)|residency]]/[[Specialist registrar|registrar]] trainng, an orthopedic surgeon is then eligible for [[American Board of Medical Specialties|board]] in the United States. In Canada it leads to eligibility for Certification by and Fellowship of the [[Royal College of Physicians and Surgeons of Canada]]. In Australia and New Zealand it leads to eligibility for Fellowship of the [[Royal Australasian College of Surgeons]].
Many orthopedic surgeons elect to do further subspecialty training in programs known as 'fellowships' after completing their residency training. Fellowship training in an orthopedic subspeciality is typically one year in duration (sometimes two) and usually has a [[research]] component involved with the clinical and operative training. Examples of orthopedic subspecialty training in the US are:
* Hand surgery (also performed by Plastic and General Surgeons)
* Shoulder and elbow surgery
* Total joint reconstruction ([[arthroplasty]])
* Pediatric orthopedics
* Foot and ankle surgery (Also performed by [[podiatric surgeons]])
* Spinal disk fusions
* Musculoskeletal oncology
* Surgical sports medicine
* Orthopedic trauma
These are also the nine main sub-specialty areas of orthopedic surgery.
Hand surgery and, more recently, Sports Medicine are the only truly recognized sub-specialties within orthopaedic surgery by the Accredited Council of Graduate Medical Education (ACGME). The other sub-specialities are informal concentrations of practice. To be recognized as a hand surgeon or sports surgeon, a practitioner must have completed an ACGME-accredited fellowship and obtained a Certificate of Added Qualifications (CAQ) which requires an additional standardized examination.
== Practice ==
Orthopedic surgeons address most musculoskeletal ailments including arthritis, trauma and congenital deformities using both surgical and non-surgical means. According to applications for board certification from 1999 to 2003, the top 25 most common procedures (in order) performed by orthopaedic surgeons are as follows:
* Knee [[arthroscopy]] and meniscectomy
* Shoulder [[arthroscopy]] and decompression
* [[Carpal tunnel]] release
* Knee [[arthroscopy]] and chondroplasty
* Removal of support implant
* Knee [[arthroscopy]] and [[anterior cruciate ligament]] reconstruction
* [[Knee replacement]]
* Repair of femoral neck [[bone fracture|fracture]]
* Repair of trochanteric [[bone fracture|fracture]]
* Debridement of [[skin]]/[[muscle]]/[[bone]]/[[bone fracture|fracture]]
* Knee [[arthroscopy]] repair of both menisci
* [[Hip replacement]]

*General orthopedics: 54.8%
*Spine surgery: 11.3%
*Sports medicine: 10.8%
*Hands and upper extremity: 8.7%
*Adult reconstructive: 3.9%
*Pediatric orthopedics: 3.4%

==History==
[[Image:X-ray3.jpg|175px|thumb|Orthopedic implants to repair fractures to the radius and ulna. Note the visible break in the ulna. (right forearm)]]
[[Jean-Andre Venel]] established the first orthopedic institute in 1780, which was the first hospital dedicated to the treatment of children's skeletal deformities. He is considered by some to be the father of orthopedics or the first true orthopedist in consideration of the establishment of his hospital and for his published methods.
[[Antonius Mathysen]], a [[Netherlands|Dutch]] [[military]] [[surgery|surgeon]], invented the [[plaster of Paris]] [[cast (orthopedic)|cast]] in 1851.
Many developments in orthopedic surgery resulted from experiences during wartime. On the battlefields of the [[Middle Ages]] the injured were treated with bandages soaked in horses' [[blood]] which dried to form a stiff, but unsanitary, splint. [[Traction (orthopedics)|Traction]] and [[Splint (medicine)|splinting]] developed during [[World War I]]. The use of [[intramedullary rod]]s to treat fractures of the [[femur]] and [[tibia]] was pioneered by Dr. Kuntschner of [[Germany]]. This made a noticeable difference to the speed of recovery of injured German soldiers during [[World War II]] and led to more widespread adoption of intramedullary fixation of [[bone fracture|fracture]]s in the rest of the world. However, traction was the standard method of treating thigh bone fractures until the late 1970s when the [[Harborview Medical Center]] in Seattle group popularized intramedullary fixation without opening up the fracture. External fixation of fractures was refined by American surgeons during the [[Vietnam War]] but a major contribution was made by [[Gavril Abramovich Ilizarov]] in the [[USSR]]. He was sent, without much orthopedic training, to look after injured Russian soldiers in [[Siberia]] in the 1950s. With no equipment he was confronted with crippling conditions of unhealed, infected, and malaligned fractures. With the help of the local [[bicycle]] shop he devised ring external [[fixator]]s tensioned like the spokes of a bicycle. With this equipment he achieved healing, realignment and [[Distraction osteogenesis|lengthening]] to a degree unheard of elsewhere. His [[Ilizarov apparatus]] is still used today as one of the [[distraction osteogenesis]] methods.
David L. MacIntosh pioneered the first successful surgery for the management of the torn [[anterior cruciate ligament]] of the [[knee]]. This common and serious injury in [[skiing|skiers]], field athletes, and [[dance]]rs invariably brought an end to their athletics due to permanent joint instability. Working with injured [[American football|football]] players, Dr. MacIntosh devised a way to re-route viable [[ligament]] from adjacent structures to preserve the strong and complex mechanics of the knee joint and restore stability. The subsequent development of ACL reconstruction surgery has allowed numerous athletes to return to the demands of sports at all levels.
Modern orthopaedic surgery and musculoskeletal research has sought to make surgery less invasive and to make implanted components better and more durable.
== Arthroscopy ==
The use of [[arthroscopy|arthroscopic tools]] has been particularly important for injured patients. Arthroscopy was pioneered in the early '''1950''''s by Dr. Masaki Watanabe of Japan to perform [[minimally invasive surgery|minimally invasive cartilage surgery and re-constructions]] of torn ligaments. Arthroscopy helped patients recover from the surgery in a matter of days, rather than the weeks to months required by conventional, 'open' surgery. Knee arthroscopy is one of the most common operations performed by orthopedic surgeons today and is often combined with meniscectomy or chondroplasty.
== Joint replacement ==
The modern total [[hip replacement]] was pioneered by Sir [[John Charnley]] in England in the 1960s.<ref name="Wroblewski2003">{{cite journal

}}</ref> He found that joint surfaces could be replaced by metal or high density [[polyethylene]] implants cemented to the bone with [[methyl methacrylate]] cement. Since Charnley, there have been continuous improvements in the design and technique of joint replacement ([[arthroplasty]]) with many contributors, including W. H. Harris, the son of R. I. Harris, whose team at Harvard pioneered uncemented arthroplasty techniques with the bone bonding directly to the implant.
Knee replacements using similar technology were started by McIntosh in [[rheumatoid arthritis]] patients and later by Gunston and Marmor for [[osteoarthritis]] in the 1970s. The modern [[knee replacement]] was developed by Dr. John Insall and Dr. [[Chitranjan Singh Ranawat]] in New York utilizing a fixed bearing,<ref name="Ranawat2002">{{cite journal

Joint replacements are available for other joints on a limited basis, most notably shoulder, elbow, wrist, ankle, and fingers.
In recent years, surface replacement of joints, in particular the hip joint, have become more popular amongst younger and more active patients. This type of operation delays the need for the more traditional and less bone-conserving total hip replacement, but carries significant risks of early failure from fracture and bone death.
One of the main problems with joint replacements is wear of the bearing surfaces of components. This can lead to damage to surrounding bone and contribute to eventual failure of the implant. Use of alternative bearing surfaces has increased in recent years, particularly in younger patients, in an attempt to improve the wear characteristics of joint replacement components. These include ceramics and all-metal implants (as opposed to the original metal-on-plastic). The plastic (actually ultra high molecular weight polyethylene) can also be altered in ways that may improve wear characteristics.
== Pediatric orthopaedics ==
The treatment of children with muscoloskeletal problems remains an integral part of modern orthopaedic surgery. Many fractures and injuries occur in children due to their high activity level and unique immature skeleton. Treatment of fractures in children is different than adults due to active [[growth plate]]s in their bones. Damage to the growth plate can lead to significant problems with later bone growth, and at-risk fractures have to be monitored with care.
The treatment of [[scoliosis]] is a mainstay of pediatric orthopaedics. For poorly understood reasons, curvature develops in the spine of some children, which if left untreated leads to undesirable deformity and may progress to cause chronic pain and breathing problems. The treatment of scoliosis is quite complicated and often involves a combination of bracing and surgery.
Children have other unique musculoskeletal conditions that have been a focus of orthopedics since Hippocrates, including conditions such as [[club foot]] and [[congenital]] [[dislocation of hip]] (also known as [[hip dysplasia|developmental dysplasia of the hip]]). In addition, [[infections]] in bones and joints ([[osteomyelitis]]) in children are common. In the US, specialized hospitals such as the [[Shriners Hospitals for Children]] have provided a substantial portion of treatment for children with musculoskeletal deformities and diseases.
