Anaesthesia: See: Anesthesia .

Anesthesia: Loss of feeling or awareness. A general anesthetic puts the person to sleep . A local anesthetic causes loss of feeling in a part of the body such as a tooth or an area of skin without affecting consciousness. Regional anesthesia numbs a larger part of the body such as a leg or arm, also without affecting consciousness. The term "conduction anesthesia" encompasses both local and regional anesthetic techniques. Many surgical procedures can be done with conduction anesthesia without significant pain . In many situations, such as a C-section , conduction anesthesia is safer and therefore preferable to general anesthesia. However, there are also many types of surgery in which general anesthesia is clearly appropriate.

Ankle pain: Pain in the ankle , a "hinged" joint. Ankle pain is commonly due to a sprain or tendinitis. The severity of ankle sprains ranges from mild (which can resolve within 24 hours) to severe (which can require surgical repair). Tendinitis of the ankle can be caused by trauma or inflammatory forms of arthritis .

Ankle sprain: A common musculoskeletal injury in which the ligaments of the ankle partially or completely tear due to sudden stretching. This typically occurs when the ankle is suddenly "twisted" in a sports activity or by stepping off an uneven surface. The pain is initially severe and can be associated with a "popping" sensation. Immediate swelling over the area of injury often occurs as the injured blood vessels leak fluid into the local tissue. Partial tears retain some ankle stability, whereas complete tears lose stability because the strapping ligaments no longer brace the ankle joint .

Arthroscopy: A surgical technique whereby a tube-like instrument is inserted into a joint to inspect, diagnose and repair tissues.  Arthroscopy is most commonly performed in patients with diseases of the knees or shoulders. The adjective "arthroscopic" is often confused with "orthoscopic." Orthoscopic means having correct vision or producing it; and free from optical distortion or designed to correct distorted vision. This fits with the prefix "ortho-", meaning straight or erect, and "-scopic" from the Greek "skopein", to see. Orthoscopic literally is to see straight. Knee surgery performed with a small scope is arthroscopic knee surgery, not orthoscopic knee surgery.

Blood pressure: The blood pressure is the pressure of the blood within the arteries. It is produced primarily by the contraction of the heart muscle . It's measurement is recorded by two numbers. The first ( systolic pressure) is measured after the heart contracts and is highest. The second ( diastolic pressure) is measured before the heart contracts and lowest. A blood pressure cuff is used to measure the pressure. Elevation of blood pressure is called " hypertension ".

Breathing: The process of respiration, during which air is inhaled into the lungs through the mouth or nose due to muscle contraction, and then exhaled due to muscle relaxation.

Calf: The belly or fleshy hind part of the leg below the knee. The calf is made up mainly of the gastrocnemius muscle (which comes from the Greek "gastroknemia" meaning calf of the leg, from "gaster" (gastr-), belly, + "kneme," leg).

Compartment syndrome: A condition in which there is swelling and an increase in pressure within a limited space (a compartment) that presses on and compromises blood vessels, nerves, and/or tendons that run through that compartment. Hence, the function of tissue within that compartment is compromised.

Fracture: A break in bone or cartilage. Although usually the result of trauma, a fracture can be caused by an acquired disease of bone such as osteoporosis or by abnormal formation of bone in a disease such as osteogenesis imperfecta ("brittle bone disease"). Fractures are classified according to their character and location as, for example, a greenstick fracture of the radius.

Orthopaedics: The branch of surgery broadly concerned with the skeletal system (bones). This particular term is commonly misspelled. Orthopedics is how this field of surgery is listed under Physicians & Surgeons in the telephone Yellow Pages in Jacksonville, Florida. This spelling is quite common today. But it is actually incorrect, erroneous, flat out wrong. Orthopedics would relate the term to the foot because in Latin pedis means foot. Orthopaedics is not merely old-fashioned. It is the correct spelling. What was meant by the term orthopaedics when it was composed goes back to its roots: ortho-, straight + the Greek paes, child = the practice, literally, of straightening the child. If the child had a crooked spine ( scoliosis ), it was the job of the orthopaedist to straighten the child, not just the child's foot. That is why there is no American Academy of Orthopedic Surgery but there is an American Academy of Orthopaedic Surgery! (And that is also why orthopaedists look after broken bones).

Outpatient: A patient who is not an inpatient (not hospitalized) but instead is cared for elsewhere -- as in a doctor's office, clinic, or day surgery center. The term outpatient dates back at least to 1715. Outpatient care today is also called ambulatory care .

Pain: An unpleasant sensation that can range from mild, localized discomfort to agony. Pain has both physical and emotional components. The physical part of pain results from nerve stimulation. Pain may be contained to a discrete area, as in an injury, or it can be more diffuse, as in disorders like fibromyalgia . Pain is mediated by specific nerve fibers that carry the pain impulses to the brain where their conscious appreciation may be modified by many factors.

Prescription: A physician's order for the preparation and administration of a drug or device for a patient. A prescription has several parts.

Skin color: The color of skin which is complexly determined. Skin color depends on many factors including reddening caused by inflammation , the hemoglobin level in the blood, and the darkening caused by increased deposition of the pigment melanin . Melanin itself is a polymer that comes in two types -- a red-yellow form known as pheomelanin and a black-brown form known as eumelanin.

Sprain: An injury to a ligament that results from overuse or trauma . Sprains occurs when there is a stretch or tear in one or more ligaments, slightly elastic bands of tissue that keep the bones in place while permitting movement at a joint. The treatment of a sprain involves applying ice packs, resting and elevating the involved joint, and using anti-inflammatory medications. Depending on the severity and location of the sprain, support bracing can help. Local cortisone injections are sometimes given for persistent inflammation . Activity may be resumed gradually. Ice application after activity can reduce or prevent recurrent inflammation. Occasionally, supportive bracing can prevent reinjury. In severe sprains, orthopedic surgical repair may be performed.

Surgeon: A physician who treats disease, injury, or deformity by operative or manual methods. A medical doctor specialized in the removal of organs, masses and tumors and in doing other procedures using a knife (scalpel).
