Reference excerpt

Hanger, Inc. (formerly Hanger Orthopedic Group, Inc.) is a leading American provider of products and services that assist in enhancing or restoring the physical capabilities of patients with disabilities or injuries that is headquartered in Austin, Texas (formerly Bethesda, Maryland). The company provides orthotic and prosthetic (O&P) services, distributes O&P devices and components, manages O&P networks, and provides therapeutic solutions to patients and businesses in acute, post-acute, and clinical settings. Hanger, Inc. operates through two segments: Patient Care and Products & Services. The primary division of Hanger, Inc.'s Patient Care segment is Hanger Clinic (formerly Hanger Prosthetics and Orthotics), which specializes in the design, fabrication, and delivery of custom O&P devices through 677 patient care clinics, with 109 satellite locations in 44 states, as well as the District of Columbia as of September 30, 2018. According to the company's 2017 annual report, the patient care market for prosthetic and orthotic services in the United States is estimated at $4 billion annually. Hanger Clinic represents about 20 percent of this market. The company employs approximately 4,600 people, including about 1,500 prosthetic and orthotic practitioners. Notable Hanger patients include:

Jeremy Campbell, winner of two gold medals in the 2008 Paralympic Games, and world-record holder for the Pentathlon P44; Aron Ralston a mountain climber who became famous in May 2003, when he amputated his lower right arm with a dull knife in order to free himself from a fallen boulder A notable non-human Hanger patient is Winter, a bottlenose dolphin (the main attraction at Clearwater Marine Aquarium) notable for her prosthetic tail (designed and manufactured by Hanger)

History James Edward Hanger, the first documented amputee of the American Civil War, founded the company in Virginia in 1861. A remark in Ambrose Bierce's postwar memoir that "We shot off a Confederate leg at Philippi" refers to Hanger. At 18 years of age, Hanger joined the Confederate cavalry at Philippi, Virginia, on June 2, 1861. One day later, during the Battle of Philippi, while Hanger was sheltering inside a stable with the rest of the Churchville (Virginia) Cavalry when the "first solid Union cannon shot of the war" bounced into the stable and struck his leg. The injury required amputation of Hanger's leg above the knee; he underwent the first battlefield amputation of the war, at the hands of Union surgeons. Hanger returned to his parents’ home to recuperate wearing a prosthesis that was essentially a wooden peg. His dissatisfaction with the fit and function of the limb replacement led Hanger to design and construct a new prosthesis from whittled barrel staves, rubber and wood, with hinges at the knee and foot. The device worked well, and the state legislature commissioned him to manufacture the “Hanger Limb” for other wounded soldiers. Manufacturing operations for J.E. Hanger, Inc., were established in the cities of Staunton and Richmond. Hanger was awarded his first patent for an artificial limb, number 155, from the Confederate Patent Office on March 23, 1863. Over the years Hanger developed and patented additional products for veterans and other amputees. In 1906, Hanger moved the company’s headquarters to Washington, DC. In 1915, he traveled to Europe to help World War I amputees and to learn from European prosthetists. Hanger’s five sons were active in operating the family business. In 1915, they divided J.E. Hanger, Inc., into four separate companies, with each operating in a different region of the country. At the time of Hanger’s death in 1919, the companies had branches in Atlanta, St. Louis, Philadelphia, Pittsburgh, London and Paris. In the years leading up to World War II, there was little significant advancement in the U.S. prosthetics industry. The new wave of amputee veterans demanded better prosthetic options, and in 1946, the federal government began providing funds for research and development in prosthetics. J.E. Hanger, Inc., was able to introduce new prosthetic socket designs made from improved materials such as thermosetting resins. Around this time, the orthotics industry sought to combine with the prosthetics industry. In 1950, the American Orthotics and Prosthetics Association was formed, which brought a new emphasis on the education and certification of clinical practitioners. By the mid 1950s, J.E.Hanger, Inc., had added orthotic services to its business, and had expanded to 50 offices in the U.S. and 25 in Europe. The 1960s and 1970s held relatively few technological improvements, but the 1980s marked the beginning of a period of advanced technological development that continues to the present day. In 1986, Sequel Corporation, a Colorado-based communications company, sold off its cellular phone business and began investing in the orthotics and prosthetics industry. In 1989, Sequel bought J. E. Hanger, Inc., of Washington, DC. At the time of purchase, J. E. Hanger, Inc., was an $8 million business with offices in 11 cities and eight states. Soon after, Sequel changed the name of the company to Hanger Orthopedic Group. Ivan Sabel, president and chief operating officer, was focused on centralizing the design and manufacturing of the company's prosthetic and orthotic devices and distributing them nationally. In 1996, the company bought J. E. Hanger, Inc., of Georgia. This acquisition doubled the size of the company, which now had 175 patient care centers, six distribution sites, four manufacturing plants and 1,000 employees in 30 states. Hanger continued purchasing small companies and by 1998, was operating 256 patient care centers. In 1999, Hanger Orthopedic Group bought its biggest competitor and the industry leader, the orthotics and prosthetics division of NovaCare. This added an additional 369 patient care centers. Following the NovaCare acquisition, the company continued to expand its corporate holdings with related specialty businesses. In 1999, Fortune Magazine ranked Hanger Orthopedic Group as 79th on its list of One Hundred Fastest-Growing Companies. In October 2022, Patient Square Capital, LP. acquired Hanger, Inc.

Worked examples

Example 1 — a first encounter with Hanger, Inc.

Start with the simplest possible case. Write down what Hanger, Inc. claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Hanger, Inc. before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Hanger, Inc. ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Hanger, Inc.

In research
Hanger, Inc. appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Hanger, Inc. in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Hanger, Inc. is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2022 mergers and acquisitions, Amputee organizations, Companies formerly listed on the New York Stock Exchange, so understanding it makes those chapters shorter.
In everyday life
Look for Hanger, Inc. outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
