Subungual Hematoma
A subungual hematoma is a collection of blood ( hematoma) underneath a toenail or fingernail. It can be extremely painful for an injury of its size, although otherwise it is not a serious medical condition. Nature A laceration of the nail bed causes bleeding into the constricted area underneath the hard nail plate. The blood pools under the nail, giving a reddish, brownish, blueish, or grey/blackish discoloration. The blood puts pressure to the nailbed causing pain which can be throbbing in quality and disappears when the pressure on the nail bed is relieved. Subungual hematomas typically heal without incident, though infection may occur. The pressure of the blood blister may cause separation of nail plate from the nail bed ( onycholysis), but the nail should not be pulled off, as this can cause scarring of the nailbed and deformed nails. Nail discolouration may last some months. The nail plate may also become thicker and more brittle as a result of the injury ( onychoch ...

Internal Medicine
Internal medicine, also known as general medicine in Commonwealth nations, is a medical specialty for medical doctors focused on the prevention, diagnosis, and treatment of diseases in adults. Its namesake stems from "treatment of diseases of the internal organs". Medical practitioners of internal medicine are referred to as internists, or physicians in Commonwealth nations. Internists possess specialized skills in managing patients with undifferentiated or multi-system disease processes. They provide care to both hospitalized (inpatient) and ambulatory (outpatient) patients and often contribute significantly to teaching and research. Internists are qualified physicians who have undergone postgraduate training in internal medicine, and should not be confused with " interns", a term commonly used for a medical doctor who has obtained a medical degree but does not yet have a license to practice medicine unsupervised. In the United States and Commonwealth nations, there is often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Electrocautery
Cauterization (or cauterisation, or cautery) is a medical practice or technique of burning a part of a body to remove or close off a part of it. It destroys some tissue in an attempt to mitigate bleeding and damage, remove an undesired growth, or minimize other potential medical harm, such as infections when antibiotics are unavailable. The practice was once widespread for treatment of wounds. Its utility before the advent of antibiotics was said to be effective at more than one level: *To prevent exsanguination *To close amputations Cautery was historically believed to prevent infection, but current research shows that cautery actually increases the risk for infection by causing more tissue damage and providing a more hospitable environment for bacterial growth. Actual cautery refers to the metal device, generally heated to a dull red glow, that a physician applies to produce blisters, to stop bleeding of a blood vessel, and for other similar purposes., page 16.

Trepanation
Trepanning, also known as trepanation, trephination, trephining or making a burr hole (the verb ''trepan'' derives from Old French from Medieval Latin from Ancient Greek, Greek , literally "borer, auger"), is a surgical intervention in which a hole is drilled or scraped into the human skull. The intentional perforation of the cranium exposes the ''dura mater'' to treat health problems related to intracranial diseases or release pressured blood buildup from an injury. It may also refer to any "Burr (cutter), burr" hole created through other body surfaces, including nail beds. A trephine is an instrument used for cutting out a round piece of skull bone to relieve pressure beneath a surface. Trepanning was sometimes performed on people who were behaving in a manner that was considered abnormal. In some ancient societies it was believed this released the evil spirits that were to blame. Evidence of trepanation has been found in prehistoric human remains from Neolithic times onward. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hallux
Toes are the digits of the foot of a tetrapod. Animal species such as cats that walk on their toes are described as being ''digitigrade''. Humans, and other animals that walk on the soles of their feet, are described as being ''plantigrade''; '' unguligrade'' animals are those that walk on hooves at the tips of their toes. Structure There are normally five toes present on each human foot. Each toe consists of three phalanx bones, the proximal, middle, and distal, with the exception of the big toe (). For a minority of people, the little toe also is missing a middle bone. The hallux only contains two phalanx bones, the proximal and distal. The joints between each phalanx are the interphalangeal joints. The proximal phalanx bone of each toe articulates with the metatarsal bone of the foot at the metatarsophalangeal joint. Each toe is surrounded by skin, and present on all five toes is a toenail. The toes are, from medial to lateral: * the first toe, also known as the h ...

Morton's Toe
Morton's toe, also known as Greek toe, is the condition of having a first metatarsal bone that is shorter than the second metatarsal (see diagram). It is a type of brachymetatarsia. This condition is the result of a premature closing of the first metatarsal's growth plate, resulting in a short big toe, giving the second toe the appearance of being long compared to the first toe. The metatarsal bones behind the toes are of different lengths, and the relative lengths vary between people. For most feet, a smooth curve can be traced through the joints at the bases of the toes (the metatarsal-phalangeal, or MTP, joints). But in Morton's foot, the line has to bend more sharply to go through the base of the big toe, as shown in the diagram. This is because the first metatarsal, behind the big toe, is short compared to the second metatarsal, next to it. The longer second metatarsal puts the MTP joint at the base of the second toe further forward. If the big toe and the second toe are ...

Ingrown Toenail
An ingrown nail, also known as onychocryptosis (from () 'nail' and () 'hidden') is a common form of nail disease. It is an often painful condition in which the nail grows so that it cuts into one or both sides of the paronychium or nail bed. While ingrown nails can occur in the nails of both the hands and the feet, they occur most commonly with the toenails (as opposed to fingernails). A common misconception is that the cause of an ingrown toenail is the nail growing into the paronychium, but it can also be caused by overgrown toe skin. The condition is caused by a microbial inflammation of the paronychium causing a granuloma within which the nail is buried. A true ''ingrown toenail'' is caused by actual penetration of flesh by a sliver of toenail. Signs and symptoms Symptoms include pain along the margins of the nail caused by hypergranulation, worsening of pain when wearing tight footwear, and sensitivity to pressure of any kind (in some cases this pressure can be a ...

United States Army Medical Corps
The Medical Corps (MC) of the U.S. Army is a staff corps (non-combat specialty branch) of the U.S. Army Medical Department (AMEDD) consisting of commissioned medical officers – physicians with either an M.D. or a D.O. degree, at least one year of post-graduate clinical training, and a state medical license. The MC traces its earliest origins to the first physicians recruited by the Medical Department of the Army, created by the Second Continental Congress in 1775. The US Congress made official the designation "Medical Corps" in 1908, although the term had long been in use informally among the Medical Department's regular physicians. Currently, the MC consists of over 4,400 active duty physicians representing all the specialties and subspecialties of civilian medicine. They may be assigned to fixed military medical facilities, to deployable combat units or to military medical research and development duties. They are considered fully deployable soldiers.

Edward Lyman Munson
Brigadier General Edward Lyman Munson (December 27, 1868 – July 7, 1947) was a senior officer of the United States Army Medical Corps. He served in several conflicts, was an instructor and teacher for matters of field hygiene and sanitation, and authored several publications. Military career Born in New Haven, Connecticut, Munson was the son of attorney and judge Lyman E. Munson. Edward L. Munson graduated from the Yale School of Medicine in 1892. He accepted a commission with the US Navy but turned it down a few months later, to join the US Army. After joining the Army in 1893, Lieutenant Munson was assigned to Fort Assinniboine in Montana. In 1889 he received a new assignment to Fort Adams, Rhode Island, but was shortly afterwards deployed with the 5th Artillery, Fifth Army Corps in Chickamauga, Georgia. As part of the Spanish–American War, the unit was sent to Cuba. Many soldiers had already been infected with Typhoid fever while being mobilized in Chickamauga; in Cuba ...

Running
Running is a method of terrestrial locomotion by which humans and other animals move quickly on foot. Running is a gait with an aerial phase in which all feet are above the ground (though there are exceptions). This is in contrast to walking, a slower form of movement where at least one foot is always in contact with the ground, the legs are kept mostly straight, and the center of gravity vaults over the stance leg or legs in an inverted pendulum fashion.Biewener, A. A. 2003. Animal Locomotion. Oxford University Press, US. books.google.com/ref> A feature of a running body from the viewpoint of Spring mass system, spring-mass mechanics is that changes in Kinetic energy, kinetic and potential energy within a stride co-occur, with energy storage accomplished by springy tendons and passive muscle elasticity. The term "running" can refer to a variety of speeds ranging from jogging to Sprint (running), sprinting. Running in humans is associated with improved health and life expect ...

Toe Box
The toe box is the section of footwear that surrounds the toes on closed-toe shoes. Toe boxes that are too tight can cause injuries and foot deformity, foot deformities, whereas wider toe boxes may be used to treat or prevent common foot conditions such as broken toes, bunions, and Morton's neuroma. Toe boxes come in a variety of shapes and styles of construction, some of which are a matter of fashion, and some of which are designed for specialized functions. Fitting The toe box of a shoe should fit the wearer's foot without cramping or compressing it. A simple way to test if a toe box is too tight is to take out the insole of the shoe and stand on it. If the toes overhang the insole, the toe box is too small for the foot. The toe box also needs enough extra room to accommodate movements of the foot, such as lengthening arches and the splay of the toes. With each step, ankles and feet bend, toes spread and flex, and the arches of the foot flatten and rebound. Because the arches f ...
