'''Fistula''' is a medical condition that involves an abnormal connection between two body parts, such as an organ or blood vessel and another structure. Fistulas are usually the result of injury or surgery, but they can also arise as a complication of certain diseases.

==Causes==
[[File:Human_fist_different_sides.svg|thumb|right|Illustration of a human fist from different angles.]]
Fistulas can be caused by a variety of factors, including [[infection]], [[surgery]], [[trauma]], or [[radiation therapy]]. Certain diseases, such as [[Crohn's disease]], can also lead to the formation of fistulas.


==Types==
A '''fist''' is a hand position in which the fingers are curled into the palm and the thumb is wrapped around the outside. This configuration is commonly used in various activities, including [[combat sports]], [[self-defense]], and [[sign language]].
There are several types of fistulas, including:


* [[Arteriovenous fistula]]: This type of fistula occurs between an artery and a vein. It is often used in dialysis treatment for patients with [[kidney disease]].
== Anatomy of a Fist ==
* [[Anal fistula]]: This type of fistula occurs in the anal region and is often a result of an abscess.
* [[Obstetric fistula]]: This type of fistula occurs between the vagina and bladder or rectum. It is often caused by prolonged or obstructed labor.


==Symptoms==
The formation of a fist involves the flexion of the [[metacarpophalangeal joints]] (knuckles) and the interphalangeal joints of the fingers. The [[muscles]] responsible for this action include the [[flexor digitorum superficialis]] and the [[flexor digitorum profundus]]. The [[thumb]] plays a crucial role in stabilizing the fist by wrapping around the outside of the fingers.
The symptoms of a fistula can vary depending on its location and type. Common symptoms can include pain, infection, and bleeding. In some cases, a fistula may not cause any symptoms.


==Treatment==
=== Bones Involved ===
Treatment for a fistula often involves surgery to repair the abnormal connection. Other treatments may include medication to treat any underlying infection or disease, and dietary changes to manage symptoms.


==See also==
The primary bones involved in forming a fist are the [[phalanges]] (finger bones) and the [[metacarpals]] (bones of the hand). The knuckles are formed by the heads of the metacarpal bones.

Fist[edit]

Illustration of a human fist from different angles.

A fist is a hand position in which the fingers are curled into the palm and the thumb is wrapped around the outside. This configuration is commonly used in various activities, including combat sports, self-defense, and sign language.

Anatomy of a Fist[edit]

The formation of a fist involves the flexion of the metacarpophalangeal joints (knuckles) and the interphalangeal joints of the fingers. The muscles responsible for this action include the flexor digitorum superficialis and the flexor digitorum profundus. The thumb plays a crucial role in stabilizing the fist by wrapping around the outside of the fingers.

Bones Involved[edit]

The primary bones involved in forming a fist are the phalanges (finger bones) and the metacarpals (bones of the hand). The knuckles are formed by the heads of the metacarpal bones.

Muscles and Tendons[edit]

The muscles that facilitate the closing of the hand into a fist are located in the forearm and hand. The tendons of these muscles pass through the wrist and attach to the bones of the fingers, allowing for the flexion necessary to form a fist.

Uses of a Fist[edit]

Combat and Self-Defense[edit]

In martial arts and boxing, the fist is used as a weapon for striking. Proper technique is essential to avoid injury, such as fractures to the metacarpal bones or damage to the ligaments of the hand.

Communication[edit]

In sign language, a fist can represent various letters and words, depending on the context and the specific sign language being used.

Cultural Significance[edit]

The fist is often used as a symbol of solidarity and resistance. The "raised fist" is a common gesture in political movements and protests.
