Arthritis is a term often used to mean any disorder that affects joints. Symptoms generally include joint pain and stiffness. Other symptoms may include redness, warmth, swelling, and decreased range of motion of the affected joints. In some types of arthritis, other organs are also affected. Onset can be gradual or sudden.
The sartorius muscle is the longest muscle in the human body. It is a long, thin, superficial muscle that runs down the length of the thigh in the anterior compartment.
In human anatomy, the ulnar nerve is a nerve that runs near the ulna bone. The ulnar collateral ligament of elbow joint is in relation with the ulnar nerve. The nerve is the largest in the human body unprotected by muscle or bone, so injury is common. This nerve is directly connected to the little finger, and the adjacent half of the ring finger, innervating the palmar aspect of these fingers, including both front and back of the tips, perhaps as far back as the fingernail beds.
Psoriatic arthritis (PsA) is a long-term inflammatory arthritis that occurs in people affected by the autoimmune disease psoriasis. The classic feature of psoriatic arthritis is swelling of entire fingers and toes with a sausage-like appearance. This often happens in association with changes to the nails such as small depressions in the nail (pitting), thickening of the nails, and detachment of the nail from the nailbed. Skin changes consistent with psoriasis frequently occur before the onset of psoriatic arthritis but psoriatic arthritis can precede the rash in 15% of affected individuals. It is classified as a type of seronegative spondyloarthropathy.
Osteophytes are exostoses that form along joint margins. They should not be confused with enthesophytes, which are bony projections that form at the attachment of a tendon or ligament. Osteophytes are not always distinguished from exostoses in any definite way, although in many cases there are a number of differences. Osteophytes are typically intra-articular.
Bouchard's nodes are hard, bony outgrowths or gelatinous cysts on the proximal interphalangeal joints. They are seen in osteoarthritis, where they are caused by formation of calcific spurs of the articular (joint) cartilage. Much less commonly, they may be seen in rheumatoid arthritis, where nodes are caused by antibody deposition to the synovium.
Nursing theory is defined as "a creative and conscientious structuring of ideas that project a tentative, purposeful, and systematic view of phenomena". Through systematic inquiry, whether in nursing research or practice, nurses are able to develop knowledge relevant to improving the care of patients. Theory refers to "a coherent group of general propositions used as principles of explanation".
Parrot's sign, refers to at least two medical signs; one relating to a large skull and another to a pupil reaction.
The extensor digitorum muscle is a muscle of the posterior forearm present in humans and other animals. It extends the medial four digits of the hand. Extensor digitorum is innervated by the posterior interosseous nerve, which is a branch of the radial nerve.
Subacute bacterial endocarditis, abbreviated SBE, is a type of endocarditis. Subacute bacterial endocarditis can be considered a form of type III hypersensitivity.
A mallet finger, also known as hammer finger or PLF finger or Hannan finger, is an extensor tendon injury at the farthest away finger joint. This results in the inability to extend the finger tip without pushing it. There is generally pain and bruising at the back side of the farthest away finger joint.
The metacarpophalangeal joints (MCP) are situated between the metacarpal bones and the proximal phalanges of the fingers. These joints are of the condyloid kind, formed by the reception of the rounded heads of the metacarpal bones into shallow cavities on the proximal ends of the proximal phalanges. Being condyloid, they allow the movements of flexion, extension, abduction, adduction and circumduction at the joint.
In human anatomy, the abductor digiti minimi is a skeletal muscle situated on the ulnar border of the palm of the hand. It forms the ulnar border of the palm and its spindle-like shape defines the hypothenar eminence of the palm together with the skin, connective tissue, and fat surrounding it. Its main function is to pull the little finger away from the other fingers.
The interphalangeal joints of the hand are the hinge joints between the phalanges of the fingers that provide flexion towards the palm of the hand.
Charles Jacques Bouchard was a French pathologist and an esperantist born in Montier-en-Der, a commune the department of Haute-Marne.
In the human hand, palmar or volar plates are found in the metacarpophalangeal (MCP) and interphalangeal (IP) joints, where they reinforce the joint capsules, enhance joint stability, and limit hyperextension. The plates of the MCP and IP joints are structurally and functionally similar, except that in the MCP joints they are interconnected by a deep transverse ligament. In the MCP joints, they also indirectly provide stability to the longitudinal palmar arches of the hand. The volar plate of the thumb MCP joint has a transverse longitudinal rectangular shape, shorter than those in the fingers.
An adjustable bed is a bed which has a multi-hinged lying surface which can be profiled to a number of different positions. Common adjustments include inclining the upper body and raising the lower body independently of each other. Other common features include height adjustment and tilting the bed to raise the upper body or the lower body into the Trendelenburg or reverse Trendelenburg positions.
Eburnation is a degenerative process of bone commonly found in patients with osteoarthritis or non-union of fractures. Friction in the joint causes the reactive conversion of the sub-chondral bone to an ivory-like surface at the site of the cartilage erosion. The word derives from Latin eburneus, which means "of ivory".
J. B. Lippincott & Co. was an American publishing house founded in Philadelphia, Pennsylvania in 1836 by Joshua Ballinger Lippincott. It was incorporated in 1885 as J. B. Lippincott Company.
A broken toe is a type of bone fracture. Symptoms include pain when the toe is touched near the break point, or compressed along its length. There may be bruising, swelling, stiffness, or displacement of the broken bone ends from their normal position.
