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
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
Ankle joint: The ankle joint is complex. It is made up of two joints: the true ankle joint and the subtalar joint:
The true ankle joint is composed of 3 bones: the tibia which forms the medial (inside) portion of the ankle; the fibula which forms the lateral (outside) portion of the ankle; and the talus underneath. The true ankle joint is responsible for the up-and-down motion of the foot.
The subtalar joint is under the true ankle joint and consists of the talus on top and calcaneus on the bottom. The subtalar joint is responsible for the side-to-side motion of the foot.
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. See the entire definition of Ankle pain
Ankylosing: Undergoing ankylosis (stiffening or fusion of a joint).
Ankylosing spondylitis: A type of arthritis that causes chronic inflammation of the spine and the sacroiliac joints. Chronic inflammation in these areas causes pain and stiffness in and around the spine. Over time, chronic spinal inflammation (spondylitis) can lead to a complete cementing together (fusion) of the vertebrae, a process called ankylosis. Ankylosis causes total loss of mobility of the spine. See the entire definition of Ankylosing spondylitis
Bacteria: Single-celled microorganisms which can exist either as independent (free-living) organisms or as parasites (dependent upon another organism for life). See the entire definition of Bacteria
Bacterial: Of or pertaining to bacteria. For example, a bacterial lung infection.
Benign: Not cancer. Not malignant. A benign tumor does not invade surrounding tissue or spread to other parts of the body. A benign tumor may grow but it stays put (in the same place). See the entire definition of Benign
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
Capsule: Capsule has many meanings in medicine including the following:
In medicine, a membranous structure that envelops an organ, a joint, tumor, or any other part of the body. It is usually made up of dense collagen-containing connective tissue.
In pharmacy, a solid dosage form in which the drug is enclosed in a hard or soft soluble container, usually of a form of gelatin.
In microbiology, a coat around a microbe, such as a bacterium or fungus.
Collateral: In anatomy, a collateral is a subordinate or accessory part. A collateral is also a side branch, as of a blood vessel or nerve. See the entire definition of Collateral
Cortisone: An adrenocorticoid hormone, a naturally occurring hormone made by and secreted by the adrenal cortex, the outer part (the cortex) of the adrenal gland. See the entire definition of Cortisone
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
Fibula: The lateral (outside) and smaller of the two long bones in the lower leg between the knee and ankle. (The other bone in the lower leg is the tibia.) See the entire definition of Fibula
Flexion: The process of bending or the state of being bent. Flexion of the fingers results in a clenched fist.
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. See the entire definition of Fracture
Gouty arthritis: An attack that is usually extremely painful of joint inflammation due to deposits of uric acid crystals in the joint fluid (synovial fluid) and joint lining (synovial lining). Intense joint inflammation occurs as white blood cells engulf the uric acid crystals, causing pain, heat, and redness of the joint tissues. The term "gout" commonly is used to refer to these painful arthritis attacks but gouty arthritis is only one manifestation of gout.
Immune: Protected against infection. The Latin immunis means free, exempt.
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.
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.
Joint: A joint is the area where two bones are attached for the purpose of motion of body parts. A joint is usually formed of fibrous connective tissue and cartilage. An articulation or an arthrosis is the same as a joint. See the entire definition of Joint
Lateral:1. In anatomy, the side of the body or a body part that is farther from the middle or center of the body. Typically, lateral refers to the outer side of the body part, but it is also used to refer to the side of a body part. For example, when referring to the knee, lateral refers to the side of the knee farthest from the opposite knee. The opposite of lateral is medial. 2. In radiology, slang for a lateral X-ray. See the entire definition of Lateral
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
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
Malleolus: Bony prominence on either side of the ankle.
Medial:1. Pertaining to the middle; in or toward the middle; nearer the middle of the body. Medial is as opposed to lateral. For example, the medial side of the knee is the side closest to the other knee whereas the lateral side of the knee is the outside of the knee. 2. Within a multilayered structure, the center layer. The medial layer of the aorta is the middle layer. For example, necrosis of the medial layer of the aorta may lead to aortic rupture. See the entire definition of Medial
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."
Naproxen: A non-steroidal anti-inflammatory drug (NSAID) used for the management of mild to moderate pain, fever, and inflammation. Naproxen blocks the enzyme cyclooxygenase that makes prostaglandins, resulting in lower concentrations of prostaglandins. As a consequence, inflammation, pain and fever are reduced. Brand names for naproxen include Anaprox, Naprelan, Naprosyn, and Aleve. See the entire definition of Naproxen
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.
Nerve compression: "Pinching" a nerve by putting too much pressure on it. For example, the sciatic nerve may be painfully compressed by a ruptured disc in the lower spine causing sciatica. See the entire definition of Nerve compression
Onset: In medicine, the first appearance of the signs or symptoms of an illness as, for example, the onset of rheumatoid arthritis. There is always an onset to a disease but never to the return to good health. The default setting is good health. See the entire definition of Onset
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
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
Posterior: The back or behind, as opposed to the anterior. See the entire definition of Posterior
Psoriatic arthritis: Joint inflammation associated with psoriasis. Psoriatic arthritis is a potentially destructive and deforming form of arthritis that affects approximately 10% of persons with psoriasis.
Reactive arthritis: A chronic form of arthritis featuring the following three conditions: (1) inflamed joints; (2) inflammation of the eyes (conjunctivitis); and (3) inflammation of the genital, urinary or gastrointestinal system. See the entire definition of Reactive arthritis
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
Rheumatoid arthritis: An autoimmune disease which causes chronic inflammation of the joints, the tissue around the joints, as well as other organs in the body. Autoimmune diseases occur when the body tissues are mistakenly attacked by its own immune system. The immune system is a complex organization of cells and antibodies designed normally to "seek and destroy" invaders of the body, particularly infections. Patients with these diseases have antibodies in their blood which target their own body tissues, where they can be associated with inflammation. Because it can affect multiple other organs of the body, rheumatoid arthritis is referred to as a systemic illness and is sometimes called rheumatoid disease. While rheumatoid arthritis is a chronic illness (meaning it can last for years) patients may experience long periods without symptoms. See the entire definition of Rheumatoid arthritis
Sensation: In medicine and physiology, sensation refers to the registration of an incoming (afferent) nerve impulse in that part of the brain called the sensorium, which is capable of such perception. Therefore, the awareness of a stimulus as a result of its perception by sensory receptors. (Sensory is here synonymous with sensation.) See the entire definition of Sensation
Shinbone: The larger of the two bones in the lower leg (the smaller one being the fibula). The shinbone is anatomically known as the tibia. See the entire definition of Shinbone
Spondylitis: Inflammation of one or more of the vertebrae of the spine. Diffuse inflammation of the spine is seen in the disease ankylosing spondylitis. Localized spondylitis is seen with infections of a certain area of the spine, such as in Pott's disease.
Symptomatic treatment: Therapy that eases the symptoms without addressing the basic cause of the disease. See the entire definition of Symptomatic treatment
Syndrome: A set of signs and symptoms that tend to occur together and which reflect the presence of a particular disease or an increased chance of developing a particular disease. See the entire definition of Syndrome
Synovitis: Inflammation of the synovial membrane, the lining of the joint.
Talus: The ankle bone. The ankle joint is formed by the talus and the bottom of the tibia and fibula that rest upon it. The Latin word "talus" means ankle and in medicine it can refer to the entire ankle, too.
Tarsal tunnel syndrome: A type of compression neuropathy (nerve disease due to compression of the nerve) in the ankle and foot. See the entire definition of Tarsal tunnel syndrome
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
Tibia: The larger of the two bones in the leg (the smaller one being the fibula). The tibia is familiarly known as the shinbone. See the entire definition of Tibia
Trauma: Any injury, whether physically or emotionally inflicted. "Trauma" has both a medical and a psychiatric definition. Medically, "trauma" refers to a serious or critical bodily injury, wound, or shock. This definition is often associated with trauma medicine practiced in emergency rooms and represents a popular view of the term. In psychiatry, "trauma" has assumed a different meaning and refers to an experience that is emotionally painful, distressful, or shocking, which often results in lasting mental and physical effects. See the entire definition of Trauma
Viral: Of or pertaining to a virus. For example, "My daughter has a viral rash."
X-ray:1. High-energy radiation with waves shorter than those of visible light. X-rays possess the properties of penetrating most substances (to varying extents), of acting on a photographic film or plate (permitting radiography), and of causing a fluorescent screen to give off light (permitting fluoroscopy). In low doses X-rays are used for making images that help to diagnose disease, and in high doses to treat cancer. Formerly called a Roentgen ray. 2. An image obtained by means of X-rays.
Rheumatoid arthritis is an autoimmune disease that causes chronic inflammation of the joints, the tissue around the joints, as well as other organs in the body. Because it can affect multiple other organs of the body, rheumatoid arthritis is referred to as a systemic illness and is sometimes called rheumatoid disease.
The knee joint is composed of three compartments and ligaments which stabilize the joint. Causes of knee pain may include injury, degeneration, infrequently infection and rarely bone tumors. Although routine x-rays do not revel meniscus tears, they can be used to exclude other problems of the bones and tissues. The knee joint is the most commonly involved joint in rheumatic disease, as well as immune diseases that affect various tissues of the body.
Foot pain may be caused by injuries (sprains, strains, bruises, and fractures), diseases (diabetes, Hansen disease, and gout), viruses, fungi, and bacteria (plantar warts and athlete's foot), or even ingrown toenails. Pain and tenderness may be accompanied by joint looseness, swelling, weakness, discoloration, and loss of function. Minor foot pain can usually be treated with rest, ice, compression, and elevation and OTC medications such as acetaminophen and ibuprofen. Severe pain should be treated by a medical professional.
Arthritis is inflammation of one or more joints. When joints are inflamed they can develop stiffness, warmth, swelling, redness and pain. There are over 100 types of
arthritis including osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, lupus, gout,
and pseudogout.
Carpal tunnel syndrome is a condition in which irritation of the wrist's median nerve causes tingling and numbness of the thumb, index, and the middle fingers. This condition is known as tarsal tunnel syndrome in the ankles and feet. Treatment of carpal tunnel syndrome depends on the severity of the symptoms and the nature of any disease that might be causing the symptoms.
Ankylosing spondylitis is a type of arthritis that causes chronic inflammation of the spine. The tendency to develop ankylosing spondylitis is genetically inherited.
Psoriatic arthritis is a disease that causes skin and joint inflammation. Symptoms include painful, stiff, and swollen joints, tendinitis, and organ inflammation. Treatment involves antiinflammatory medications and exercise.
Fractures occur when bone cannot withstand the outside forces applied to the bone. Fractures can be open or closed. Types of fractures include: greenstick, spiral, comminuted, transverse, compound, or vertebral compression. Common fractures include: stress fracture, compression fracture, rib fracture, and skull fracture. Treatment depends upon the type of fracture.
Bone spurs are pointy outgrowths of bone that develop in areas of inflammation or injury. They commonly occur on the heel and spine and may be the result of reactive arthritis, ankylosing spondylitis, or diffuse idiopathic skeletal hyperostosis. Symptoms include pain, numbness, and tenderness. Treatment focuses on decreasing inflammation and avoiding re-injury.
Heel spurs, pointed, bony outgrowths of the heel, are caused by localized soft tissue inflammation and can be located at the back of the heel or under the heel, beneath the sole of the foot. Plantar fascitis is associated with inflammation caused by heel spurs on the soles of the feet. Both conditions are treated with ice application and anti-inflammatory medications. Orthotics may also provide some relief.
An injury to a ligament is called a sprain, and an injury to muscle or tendon is called a strain. Sprains and strains may be caused by repetitive movements or a single stressful incident. Symptoms include pain and swelling. Though treatment depends upon the extent and location of the injury, rest, ice, compression, and elevation are key elements of treatment.
There are several bones in the foot, and these bones can be broken (fractured) in a variety of ways. Falling from heights, dropping heavy objects on the foot, or stress fractures from running or walking. Treatment of a broken foot depends on what bone in the foot is broken.
Chronic pain is pain (an unpleasant sense of discomfort) that persists or progresses over a long period of time. In contrast to acute pain that arises suddenly in response to a specific injury and is usually treatable, chronic pain persists over time and is often resistant to medical treatments.
Reactive arthritis is a chronic, systemic rheumatic disease characterized by three conditions, including conjunctivitis, joint inflammation, and genital, urinary or gastrointestinal system inflammation. Inflammation leads to pain, swelling, warmth, redness, and stiffness of the affected joints. Non-joint areas may experience irritation and pain. Treatment for reactive arthritis depends on which area of the body is affected. Joint inflammation is treated with antiinflammatory medications.
Nonsteroidal antiinflammatory drugs (NSAIDs) are prescribed medications for the treatment of inflammatory conditions. Examples of NSAIDs include aspirin, ibuprofen, naproxen, and more. One common side effect of NSAIDs is peptic ulcer (ulcers of the esophagus, stomach, or duodenum). Side effects, drug interactions, warnings and precautions, and patient safety information should be reviewed prior to taking NSAIDs.
Sever condition is an inflammation of the growth plate of the bone at the back of the heel where the Achilles tendon attaches. Sever condition can be very painful and is commonly referred to as "growing pains." The condition often disappears with age, but it can also be treated by limiting activity, using antiinflammatory medications, shoe inserts, and heel lifts.
The foot is designed to withstand the considerable forces
placed on it by walking, running, and jumping. The 26 bones of the foot are
connected by joints and supported by thickened ligaments to absorb the impact of movement. As well,
the joints of the foot are acted upon by tendons that allow flexing and
extending to permit walking and running to occur.
The bony anatomy can be described as follows:
The talus articulates with the
tibia (shin bone) to form the
ankle joint.
The calcaneus or the heel
bone is attached by ligaments to the tibia to
provide stability to the ankle joint.
The midfoot consists of the navicular, the cuboid, and the three cuneiform
bones. The midfoot is where inversion and
supination of the foot occurs. These
motions allow the sole of the foot to turn inwards and upwards.
