Orthopedic surgery
Encyclopedia
Orthopedic surgery or orthopedics (also spelled orthopaedic surgery and orthopaedics in British English
) is the branch of surgery
concerned with conditions involving the musculoskeletal system
. Orthopedic surgeons use both surgical and nonsurgical means to treat musculoskeletal trauma
, sports injuries, degenerative disease
s, infection
s, tumor
s, and congenital disorder
s.
Nicholas Andry coined the word "orthopaedics", derived from Greek
word
s for orthos ("correct", "straight") and paideion ("child"), when he published Orthopaedia: or the Art of Correcting and Preventing Deformities in Children in 1741. Correction of spinal and bony deformities became the cornerstone of orthopedic practice. Today, over 6 months of training is dedicated to the treatment of the pediatric population.
In the United States orthopedics is standard, although the majority of college, university and residency programs, and even the American Academy of Orthopaedic Surgeons, still use the spelling with the Latinate digraph ae. Elsewhere, usage is not uniform; in Canada, both spellings are acceptable; orthopaedics usually prevails in the rest of the Commonwealth, especially in Britain.
training in orthopedic surgery. The five-year residency consists of one year of general surgery training followed by four years of training in orthopedic surgery.
Selection for residency training in orthopedic surgery is very competitive. Approximately 700 physicians complete orthopedic residency training per year in the United States. About 10 percent of current orthopedic surgery residents are women; about 20 percent are members of minority groups. There are approximately 20,400 actively practicing orthopedic surgeons and residents in the United States. According to the latest Occupational Outlook Handbook (2009–2010) published by the United States Department of Labor
, between 3–4% of all practicing physicians are orthopedic surgeons.
Many orthopedic surgeons elect to do further training, or fellowships, after completing their residency training. Fellowship training in an orthopedic subspecialty is typically one year in duration (sometimes two) and sometimes has a research
component involved with the clinical and operative training. Examples of orthopedic subspecialty training in the United States are:
These specialty areas of medicine are not exclusive to orthopedic surgery. For example, hand surgery is practiced by some plastic surgeons and spine surgery is practiced by most neurosurgeons. Additionally, foot and ankle surgery is practiced by board-certified Doctors of Podiatric Medicine (D.P.M.) in the United States. Some family practice physicians practice sports medicine; however, their scope of practice is non-operative.
After completion of specialty residency

training, an orthopedic surgeon is then eligible for board certification
. Certification by the American Board of Orthopaedic Surgery means that the orthopedic surgeon has met the specified educational, evaluation, and examination requirements of the Board. The process requires successful completion of a standardized written exam followed by an oral exam focused on the surgeon's clinical and surgical performance over a 6-month period. In Canada, the certifying organization is the Royal College of Physicians and Surgeons of Canada
; in Australia and New Zealand it is the Royal Australasian College of Surgeons
.
In the United States, specialists in hand surgery and sports medicine may obtain a Certificate of Added Qualifications (CAQ) in addition to their board certification by successfully completing a separate standardized examination. There is no additional certification process for the other subspecialties.
A typical schedule for a practicing orthopedic surgeon involves 50–55 hours of work per week divided among clinic, surgery, various administrative duties and possibly teaching and/or research if in an academic setting. In 2009, the median salary for an orthopedic surgeon in the United States was $406,847.
Antonius Mathysen, a Dutch
military
surgeon
, invented the plaster of Paris 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
and splinting
developed during World War I
. The use of intramedullary rod
s to treat fractures of the femur
and tibia
was pioneered by Gerhard Küntscher
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 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 fixators tensioned like the spokes of a bicycle. With this equipment he achieved healing, realignment and lengthening
to a degree unheard of elsewhere. His Ilizarov apparatus
is still used today as one of the distraction osteogenesis
methods.
Ruth Jackson
became the first female Board-certified Orthopaedic Surgeon in the U.S in 1937. Orthopedics continues to be a male-dominated field. In 2006, 12.4% of orthopedics residents were women.
David L. MacIntosh pioneered the first successful surgery for the management of the torn anterior cruciate ligament
(ACL) of the knee
. This common and serious injury in skiers
, field athletes, and dance
rs invariably brought an end to their athletics due to permanent joint instability. Working with injured 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 orthopedic surgery and musculoskeletal research has sought to make surgery less invasive and to make implanted components better and more durable.
was pioneered in the early 1950s by Dr. Masaki Watanabe of Japan to perform minimally invasive cartilage surgery and reconstructions 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. The majority of orthopedic procedures are now performed arthroscopically.
was pioneered by Sir John Charnley
in England in the 1960s. He found that joint surfaces could be replaced by metal or high density polyethylene
implants cemented to the bone with methyl methacrylate
bone 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 developed by Dr John Insall
in New York utilizing a fixed bearing system, and by Dr Frederick Buechel and Dr Michael Pappas utilizing a mobile bearing system.
Uni-compartmental knee replacement, in which only one weight-bearing surface of an arthritic knee is replaced, is an alternative to a total knee replacement in a select patient population.
Joint replacements are available for other joints on a limited basis, most notably shoulder, elbow, wrist, ankle, spine, 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.

Bone cement
Bone cements have been used very successfully to anchor artificial joints for more than half a century. Artificial joints are anchored with bone cement. The bone cement fills the free space between the prosthesis and the bone and plays the important role of an elastic zone...
. Since Charnley, there have been continuous improvements in the design and technique of joint replacement
Joint replacement
Replacement arthroplasty [from Greek arthron, joint, limb, articulate, + -plassein, to form, mould, forge, feign, make an image of], or joint replacement surgery, is a procedure of orthopedic surgery in which the arthritic or dysfunctional joint surface is replaced with an orthopaedic prosthesis...

Knee replacements using similar technology were started by McIntosh in rheumatoid arthritis
Rheumatoid arthritis
Rheumatoid arthritis is a chronic, systemic inflammatory disorder that may affect many tissues and organs, but principally attacks synovial joints. The process produces an inflammatory response of the synovium secondary to hyperplasia of synovial cells, excess synovial fluid, and the development...

Uni-compartmental knee replacement, in which only one weight-bearing surface of an arthritic knee is replaced, is an alternative to a total knee replacement in a select patient population.
Joint replacements are available for other joints on a limited basis, most notably shoulder, elbow, wrist, ankle, spine, 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.
