Achilles Tendon Rupture Glossary of Terms

The following are health and medical definitions of terms that appear in the Achilles Tendon Rupture article.

Acetaminophen: A pain reliever and fever reducer. Brand name: Tylenol. The exact mechanism of action of acetaminophen is not known. Acetaminophen relieves pain by elevating the pain threshold (that is, by requiring a greater amount of pain to develop before it is felt by a person). Acetaminophen reduces fever through its action on the heat-regulating center (the "thermostat") of the brain. Generic is available.

Achilles: In Greek mythology, the hero who was thought to have some special medical knowledge. Achilles studied medicine with Chiron, the centaur, who invented it.
See the entire definition of Achilles

Achilles tendon: A tough sinew that attaches the calf muscle to the back of the heel bone. The Achilles tendon is one of the longest tendons in the body. It is also called the tendo Achilles or the tendo calcaneus, the calcaneus being the heel bone.
See the entire definition of Achilles tendon

Acute: Of abrupt onset, in reference to a disease. Acute often also connotes an illness that is of short duration, rapidly progressive, and in need of urgent care.
See the entire definition of Acute

Adjacent: Lying nearby. Related terms include superjacent, subjacent, and circumjacent. From ad-, near + the Latin jacere, to lie = to lie near.

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: The ankle joint is complex. It is made up of two joints: the true ankle joint and the subtalar joint:
See the entire definition of Ankle

Arthritis: Inflammation of a joint. When joints are inflamed they can develop stiffness, warmth, swelling, redness and pain. There are over 100 types of arthritis. (see osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, lupus, gout, pseudogout).

Atrophy: Wasting away or diminution. Muscle atrophy is wasting of muscle, decrease in muscle mass.
See the entire definition of Atrophy

Blood clots: Blood that has been converted from a liquid to a solid state. Also called a thrombus.
See the entire definition of Blood clots

Calcaneus: The calcaneus is the heel bone. It is also called the os calcis. The calcaneus is a more or less rectangular bone at the back of the foot.
See the entire definition of Calcaneus

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).
See the entire definition of Calf

Cast: 1) A protective shell of fiberglass, plastic, or plaster, and bandage that is molded to protect broken or fractured limb(s) as it heals. 2) An abnormal mass of dead cells that forms in a body cavity. For example, cases of cells that form in the tubules of the kidneys are sometimes detected in urine samples.

Conditioning: 1) Exercise and practice to build the body up for either improved normal performance, as in physical therapy, or in preparation for sports performance. 2) A method of educating involving repetitive activities to influence behavior.

Depression: An illness that involves the body, mood, and thoughts, that affects the way a person eats and sleeps, the way one feels about oneself, and the way one thinks about things. A depressive disorder is not the same as a passing blue mood. It is not a sign of personal weakness or a condition that can be wished away. People with a depressive disease cannot merely "pull themselves together" and get better. Without treatment, symptoms can last for weeks, months, or years. Appropriate treatment, however, can help most people with depression.
See the entire definition of Depression back to top

Diabetes: Refers to diabetes mellitus or, less often, to diabetes insipidus. Diabetes mellitus and diabetes insipidus share the name "diabetes" because they are both conditions characterized by excessive urination (polyuria).
See the entire definition of Diabetes

Diagnosis: 1 The nature of a disease; the identification of an illness. 2 A conclusion or decision reached by diagnosis. The diagnosis is rabies. 3 The identification of any problem. The diagnosis was a plugged IV.
See the entire definition of Diagnosis

Drain: A device for removing fluid from a cavity or wound. A drain is typically a tube or wick. As a verb, to allow fluid to be released from a confined area.

Emergency department: The department of a hospital responsible for the provision of medical and surgical care to patients arriving at the hospital in need of immediate care. Emergency department personnel may also respond to certain situations within the hospital such cardiac arrests.
See the entire definition of Emergency department

Fascia: A flat band of tissue below the skin that covers the underlying tissues and separates different layers of tissue. Fascia encloses muscles. Inflammation of the fascia is referred to as fasciitis.
See the entire definition of Fascia

Heart: The muscle that pumps blood received from veins into arteries throughout the body. It is positioned in the chest behind the sternum (breastbone; in front of the trachea, esophagus, and aorta; and above the diaphragm muscle that separates the chest and abdominal cavities. The normal heart is about the size of a closed fist, and weighs about 10.5 ounces. It is cone-shaped, with the point of the cone pointing down to the left. Two-thirds of the heart lies in the left side of the chest with the balance in the right chest.
See the entire definition of Heart

Heel bone: Formally called the calcaneus. A more or less rectangular bone at the back of the foot. The words "calcaneus" and "calcium" come from the same source.

Ibuprofen: A non-steroidal anti-inflammatory drug (NSAID) commonly used to treat pain, swelling, and fever. Common brand names for Ibuprofen include Advil, Motrin, and Nuprin.

Incidence: The frequency with which something, such as a disease, appears in a particular population or area. In disease epidemiology, the incidence is the number of newly diagnosed cases during a specific time period. The incidence is distinct from the prevalence which refers to the number of cases alive on a certain date.

Indicate: In medicine, to make a treatment or procedure advisable because of a particular condition or circumstance. For example, certain medications are indicated for the treatment of hypertension during pregnancy while others are contraindicated.

Infection: The growth of a parasitic organism within the body. (A parasitic organism is one that lives on or in another organism and draws its nourishment therefrom.) A person with an infection has another organism (a "germ") growing within him, drawing its nourishment from the person.
See the entire definition of Infection

Inflammation: A basic way in which the body reacts to infection, irritation or other injury, the key feature being redness, warmth, swelling and pain. Inflammation is now recognized as a type of nonspecific immune response.
See the entire definition of Inflammation

Injury: Harm or hurt. The term "injury" may be applied in medicine to damage inflicted upon oneself as in a hamstring injury or by an external agent on as in a cold injury. The injury may be accidental or deliberate, as with a needlestick injury. The term "injury" may be synonymous (depending on the context) with a wound or with trauma.

Knee: The knee is a joint which has three parts. The thigh bone (the femur) meets the large shin bone (the tibia) to form the main knee joint. This joint has an inner (medial) and an outer (lateral) compartment. The kneecap (the patella) joins the femur to form a third joint, called the patellofemoral joint. The patella protects the front of the knee joint.
See the entire definition of Knee

Leg: In popular usage, the leg extends from the top of the thigh down to the foot. However, in medical terminology, the leg refers to the portion of the lower extremity from the knee to the ankle.
See the entire definition of Leg back to top

Ligament: A ligament is a tough band of connective tissue that connects various structures such as two bones.
See the entire definition of Ligament

Lower leg: The lower leg is the bottom segment of the leg: the part below the knee.
See the entire definition of Lower leg

Metatarsal: One of the five cylindrical bones extending from the heel (the tarsus) to the toes on each foot. The metatarsals are numbered from the inside out, so the first metatarsal extends to the big toe and the fifth metatarsal goes to the littlest toe.

MRI: Abbreviation and nickname for magnetic resonance imaging. For more information, see: Magnetic Resonance Imaging; Paul C. Lauterbur; Peter Mansfield.

Muscle: Muscle is the tissue of the body which primarily functions as a source of power. There are three types of muscle in the body. Muscle which is responsible for moving extremities and external areas of the body is called "skeletal muscle." Heart muscle is called "cardiac muscle." Muscle that is in the walls of arteries and bowel is called "smooth muscle."

Nerve: A bundle of fibers that uses chemical and electrical signals to transmit sensory and motor information from one body part to another. See: Nervous system.

Objective: In a microscope, the objective (also called the objective lens) is the lens nearest to the object being examined whereas the lens closest to the eye is termed the ocular (the eyepiece).
See the entire definition of Objective

Operation: Although there are many meanings to the word "operation", in medicine it refers to a surgical procedure.
See the entire definition of Operation

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.
See the entire definition of Pain

Pharmacy: A location where prescription drugs are sold. A pharmacy is, by law, constantly supervised by a licensed pharmacist.

Physical therapist: A person trained and certified by a state or accrediting body to design and implement physical therapy programs. Physical therapists may work within a hospital or clinic, in a school providing assistance to special education students, or as an independent practitioner.

Physical therapy: A branch of rehabilitative health that uses specially designed exercises and equipment to help patients regain or improve their physical abilities. Physical therapists work with many types of patients, from infants born with musculoskeletal birth defects, to adults suffering from sciatica or the after- effects of injury, to elderly post-stroke patients.

Plantar: Having to do with the sole of the foot.
See the entire definition of Plantar

Prognosis: 1. The expected course of a disease.
2. The patient's chance of recovery.
The prognosis predicts the outcome of a disease and therefore the future for the patient. His prognosis is grim, for example, while hers is good.
See the entire definition of Prognosis

Rehabilitation: The process of restoration of skills by a person who has had an illness or injury so as to regain maximum self-sufficiency and function in a normal or as near normal manner as possible. For example, rehabilitation after a stroke may help the patient walk again and speak clearly again.
See the entire definition of Rehabilitation back to top

Rupture: A break or tear in any organ (such as the spleen) or soft tissue (such as the achilles tendon). Rupture of the appendix is more likely among uninsured and minority children when they develop appendicitis.

Spasm: A brief, automatic jerking movement. A muscle spasm can be quite painful, with the muscle clenching tightly. A spasm of the coronary artery can cause angina. Spasms in various types of tissue may be caused by stress, medication, over-exercise, or other factors.

Stomach: 1. The sac-shaped digestive organ that is located in the upper abdomen, under the ribs. The upper part of the stomach connects to the esophagus, and the lower part leads into the small intestine.
See the entire definition of Stomach

Strain: 1. An injury to a tendon or muscle resulting from overuse or trauma. 2. A hereditary tendency that originated from a common ancestor. 3. To exert maximum effort. 4. To filter.

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). The definition of a "surgeon" has begun to blur in recent years as surgeons have begun to minimize the cutting, employ new technologies that are "minimally invasive," use scopes, etc.
See the entire definition of Surgeon

Surgery: The word "surgery" has multiple meanings. It is the branch of medicine concerned with diseases and conditions which require or are amenable to operative procedures. Surgery is the work done by a surgeon. By analogy, the work of an editor wielding his pen as a scalpel is s form of surgery. A surgery in England (and some other countries) is a physician's or dentist's office.
See the entire definition of Surgery

Suture: 1. A type of joint between the bones of the skull where the bones are held tightly together by fibrous tissue. 2. Thread-like material used to sew tissue together. 3. To stitch a wound closed.

The word suture came with little change from the Latin sutura, "a sewn seam." In Latin, the verb suere is "to sew, stitch, or tack together."

Tear: A drop of the salty secretion of the lacrimal glands which serves to moisten the conjunctiva and cornea.

Tendinitis: Inflammation of a tendon (the tissue by which muscle attaches to bone). Tendinitis most commonly occurs as a result of injury, such as to the tendons around the shoulder or elbow. It can also occur as a result of an underlying inflammatory rheumatic disease, such as reactive arthritis or gout. Tendinitis is synonymous with tendonitis.

Tendon: The tissue by which a muscle attaches to bone. A tendon is somewhat flexible, but fibrous and tough. When a tendon becomes inflamed, the condition is referred to as tendinitis or tendonitis. Inflamed tendons are at risk for rupture.
See the entire definition of Tendon

Tension: 1) The pressure within a vessel, such as blood pressure: the pressure within the blood vessels. For example, elevated blood pressure is referred to as hypertension. 2) Stress, especially stress that is translated into clenched scalp muscles and bottled-up emotions or anxiety. This is the type of tension blamed for tension headaches.

Therapy: The treatment of disease.
See the entire definition of Therapy

Thigh: The thigh extends from the hip to the knee. The thigh has only one bone, the femur which is the largest bone in the human body.
See the entire definition of Thigh

Tylenol: See: Acetaminophen.

Ultrasound: High-frequency sound waves. Ultrasound waves can be bounced off of tissues using special devices. The echoes are then converted into a picture called a sonogram. Ultrasound imaging, referred to as ultrasonography, allows physicians and patients to get an inside view of soft tissues and body cavities, without using invasive techniques. Ultrasound is often used to examine a fetus during pregnancy. There is no convincing evidence for any danger from ultrasound during pregnancy.

Achilles Tendon Rupture

Ruptured Tendon Overview

A tendon is the fibrous tissue that attaches muscle to bone in the human body. The forces applied to a tendon may be more than 5 times your body weight. In some rare instances, tendons can snap or rupture. Conditions that make a rupture more likely include the injection of steroids into a tendon, certain diseases (such as gout or hyperparathyroidism), and having type O blood.

Although fairly uncommon, a tendon rupture can be a serious problem and may result in excruciating pain and permanent disability if untreated. Each type of tendon rupture has its own signs and symptoms and can be treated either surgically or medically depending on the severity of the rupture and the confidence of the surgeon.

The 4 most common areas of tendon rupture are as follows:

  • Quadriceps

    • A group of 4 muscles, the vastus lateralis, vastus medialis, vastus intermedius, and the rectus femoris, come together just abo...
