Little League Elbow
Little League elbow is a condition that is caused by repetitive throwing motions, especially in children who play sports that involve an overhand throw. "Little Leaguer's elbow" was coined by Brogdon and Crow in an eponymous 1960 article in the American Journal of Radiology. The name of the condition is derived from the game of baseball. Compared to athletes who play other sports, baseball players are at higher risk of overuse injuries and injuries caused by early sports specialization by children and teenagers. Little League elbow is most often seen in young pitchers under the age of sixteen. The pitching motion causes a valgus stress to be placed on the elbow joint which can cause damage to the structures of the elbow, resulting in an avulsion of the medial epiphyseal plate (growth plate). The first diagnosis of the injury in 1960 set off a firestorm of controversy regarding how much youth baseball players can and should be asked to pitch. The ailment even appeared in the com ...

Baseball Pitch
In baseball, the pitch is the act of throwing the baseball toward home plate to start a play. The term comes from the Knickerbocker Rules. Originally, the ball had to be thrown underhand, much like "pitching in horseshoes". Overhand pitching was not allowed in baseball until 1884. The biomechanics of pitching have been studied extensively. The phases of pitching include the windup, early cocking, late cocking, early acceleration, late acceleration, deceleration, and follow-through. Pitchers throw a variety of pitches, each of which has a slightly different velocity, trajectory, movement, hand position, wrist position and/or arm angle. These variations are introduced to confuse the batter and ultimately aid the defensive team in getting the batter or baserunners out. To obtain variety, and therefore enhance defensive baseball strategy, the pitcher manipulates the grip on the ball at the point of release. Variations in the grip cause the seams to catch the air differently, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Journal Of Radiology
The American Journal of Roentgenology (''AJR'') is a monthly peer-reviewed journal that covers topics in radiology. It is published by the American Roentgen Ray Society (ARRS) and is based in Leesburg, VA. The current editor-in-chief (August 2020) is Andrew B. Rosenkrantz. History The publication has undergone several changes throughout its history. The initial publication in 1906 was entitled the ''American Quarterly of Roentgenology'', and was officially associated with the ARRS in 1909. In 1913, journal was renamed the ''American Journal of Roentgenology'', and publication frequency was increased to a monthly basis under editor Preston M. Hickey. Hickey would remain editor-in-chief for approximately 10 years, and became a pioneering voice for evolution of radiologic education and reporting. With the advent of radiation therapy and nuclear medicine under the auspices of radiology, there was a period from 1920 to 1970s during which the ARRS began publishing articles on topics o ...

Ulnar Collateral Ligament Of Elbow Joint
The ulnar collateral ligament (UCL) or internal lateral ligament is a thick triangular ligament at the medial aspect of the elbow uniting the distal aspect of the humerus to the proximal aspect of the ulna. Structure It consists of two portions, an anterior and posterior united by a thinner intermediate portion. Note that this ligament is also referred to as the medial collateral ligament and should not be confused with the lateral ulnar collateral ligament (LUCL). The ''anterior portion'', directed obliquely forward, is attached, above, by its apex, to the front part of the medial epicondyle of the humerus; and, below, by its broad base to the medial margin of the coronoid process of the ulna. The ''posterior portion'', also of triangular form, is attached, above, by its apex, to the lower and back part of the medial epicondyle; below, to the medial margin of the olecranon. Between these two bands a few intermediate fibers descend from the medial epicondyle to blend with a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Baseball Pitching
In baseball, the pitcher is the player who throws ("pitches") the baseball from the pitcher's mound toward the catcher to begin each play, with the goal of retiring a batter, who attempts to either make contact with the pitched ball or draw a walk. In the numbering system used to record defensive plays, the pitcher is assigned the number 1. The pitcher is often considered the most important player on the defensive side of the game, and as such is situated at the right end of the defensive spectrum. There are many different types of pitchers, such as the starting pitcher, relief pitcher, middle reliever, lefty specialist, setup man, and the closer. Traditionally, the pitcher also bats. Starting in 1973 with the American League(and later the National League) and spreading to further leagues throughout the 1980s and 1990s, the hitting duties of the pitcher have generally been given over to the position of designated hitter, a cause of some controversy.

Panner Disease
Panner disease is an osteochondrosis of the capitellum of the elbow. Panner disease is primarily seen in boys between the ages of five and ten years old. Panner disease is often caused by excessive throwing due to valgus stress. The disease causes pain and stiffness in the affected elbow and may limit extension; the affected elbow is usually on the dominant arm the child uses. The disease may be associated with pitching and athletic activity. On radiographs, the capitellum may appear irregular with areas of radiolucency. Treatment is symptomatic, with a good prognosis. Treatment is minimal and includes restricting athletic activity to allow for the elbow to heal and for pain to be relieved. The disease is named after the Danish radiologist Hans Jessen Panner (1871–1930). Symptoms An individual with Panner disease most commonly experiences elbow pain near the capitellum. Other symptoms include: * Stiffness in the elbow * Elbow swelling * Limited range of motion * Elbow extensi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radial Tunnel Syndrome
Radial tunnel syndrome (RTS) is caused by increased pressure on the radial nerve as it travels from the upper arm (the brachial plexus) to the hand and wrist. Symptoms and signs Radial tunnel syndrome causes posterolateral elbow pain that is similar to tennis elbow and may sometimes occur in conjunction with that condition. Patients may typically have weakness of extension at the wrist and third digit. The pain is often reproduced upon resisted supination of the forearm, and pain at the radial tunnel on resisted hyperextension of the wrist. Cause The theory is that the radial nerve becomes irritated and/or inflamed from friction caused by compression by muscles in the forearm. Some speculate that radial tunnel syndrome is a type of repetitive strain injury (RSI), but there is no detectable pathophysiology and even the existence of this disorder is questioned. The term "radial tunnel syndrome" is used for compression of the posterior interosseous nerve, a division of the radial ne ...

Repetitive Strain Injury
A repetitive strain injury (RSI) is an injury to part of the musculoskeletal or nervous system caused by repetitive use, vibrations, compression or long periods in a fixed position. Other common names include repetitive stress disorders, cumulative trauma disorders (CTDs), and overuse syndrome. Signs and symptoms Some examples of symptoms experienced by patients with RSI are aching, pulsing pain, tingling and extremity weakness, initially presenting with intermittent discomfort and then with a higher degree of frequency. Definition Repetitive strain injury (RSI) and associative trauma orders are umbrella terms used to refer to several discrete conditions that can be associated with repetitive tasks, forceful exertions, vibrations, mechanical compression, sustained or awkward positions, or repetitive eccentric contractions. The exact terminology is controversial, but the terms now used by the United States Department of Labor and the National Institute of Occupational Safe ...

Golfer's Elbow
Golfer's elbow, or medial epicondylitis, is tendinosis of the medial epicondyle on the inside of the elbow. It is in some ways similar to tennis elbow, which affects the outside at the lateral epicondyle. The anterior forearm contains several muscles that are involved with flexing the digits of the hand, and flexing and pronating the wrist. The tendons of these muscles come together in a common tendinous sheath, which originates from the medial epicondyle of the humerus at the elbow joint. In response to minor injury, this point of insertion becomes inflamed, causing pain. Causes The condition is called ''golfer's elbow'' because in making a golf swing this tendon is stressed, especially if a non-overlapping (baseball style) grip is used; however, many people develop the condition without playing golf. It is also sometimes called ''pitcher's elbow'' due to the same tendon being stressed by the throwing of objects such as a baseball, but this usage is much less frequent. Other ...

Tennis Elbow
Tennis elbow, also known as lateral epicondylitis or enthesopathy of the extensor carpi radialis origin, is a condition in which the outer part of the elbow becomes painful and tender. The pain may also extend into the back of the forearm. Onset of symptoms is generally gradual although they can seem sudden and be misinterpreted as an injury. Golfer's elbow is a similar condition that affects the inside of the elbow. Enthesopathies are idiopathic, meaning science has not yet determined the cause. Enthesopathies are most common in middle age (ages 35 to 60). It is often stated that the condition is caused by excessive use of the muscles of the back of the forearm, but this is not supported by experimental evidence and is a common misinterpretation or unhelpful thought about symptoms. It may be associated with work or sports, classically racquet sports, but most people with the condition are not exposed to these activities. The diagnosis is based on the symptoms and examination ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tommy John Surgery
Ulnar collateral ligament reconstruction, colloquially known as Tommy John surgery (TJS), is a surgical graft procedure where the ulnar collateral ligament in the medial elbow is replaced with either a tendon from elsewhere in the patient's body, or with one from a deceased donor. The procedure is common among collegiate and professional athletes in several sports, particularly in baseball. The procedure was devised in 1974 by orthopedic surgeon Frank Jobe, a Los Angeles Dodgers team physician who served as a special advisor to the team until his death in 2014. It is named after the first baseball player to undergo the surgery, major league pitcher Tommy John, whose record of 288 career victories ranks seventh among left-handed pitchers. The initial operation, John's successful post-surgery career, and the relationship between the two men was the subject of a 2013 ESPN ''30 for 30'' documentary. Uses The ulnar collateral ligament (UCL) can become stretched, frayed or torn thr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charlie Brown
Charles "Charlie" Brown is the principal character of the comic strip ''Peanuts'', syndicated in daily and Sunday newspapers in numerous countries all over the world. Depicted as a "lovable loser," Charlie Brown is one of the great American archetypes and a popular and widely recognized cartoon character. Charlie Brown is characterized as a person who frequently suffers, and as a result, is usually nervous and lacks self-confidence. He shows both pessimistic and optimistic attitudes: on some days, he is apprehensive to even go outside because his day might just be spoiled, but on others, he hopes for the best and tries as much as he can to accomplish things. He is easily recognized by his trademark zigzag patterned shirt. The character's creator, Charles M. Schulz, said that Charlie Brown "must be the one who suffers because he is a caricature of the average person. Most of us are much more acquainted with losing than winning." Despite this, Charlie Brown does not always suffer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
