Lymph	infraclavicular lymph nodes[1]
MeSH	Thumb

The thumb is the first digit of the hand. When a person is standing in the medical anatomical position (where the palm is facing anteriorly), the thumb is the lateral-most digit. The Medical Latin English noun for thumb is pollex (compare hallux for big toe), and the corresponding adjective for thumb is pollical.

Definition[link]

As one of five digits, and as companion to four other fingers[link]

The English word "finger" has two senses, even in the context of appendages of a single typical human hand:

1. Any of the five digits.
2. Any of the five terminal members of the hand, especially those other than the thumb.

Linguistically, it appears that the original sense was the broader of these two: penkwe-ros (also rendered as penqrós) was, in the inferred Proto-Indo-European language, a suffixed form of penkwe (or penqe), which has given rise to many Indo-European-family words (tens of them defined in English dictionaries) that involve or flow from concepts of fiveness.

The thumb shares the following with each of the other four fingers:

• Having a skeleton of phalanges, joined by hinge-like joints that provide flexion toward the palm of the hand
• Having a "back" surface that features hair and a nail, and a hairless palm-of-the-hand side with fingerprint ridges instead

The thumb contrasts with each of the other four by being the only digit that:

• Is opposable to the other four fingers
• Has two phalanges rather than three
• Has greater breadth in the distal phalanx than in the proximal phalanx
• Is attached to such a mobile metacarpus (which produces most of the opposability)

and hence the etymology of the word: "tum" is Proto-Indo-European for " swelling " (cf "tumour" and "thigh") since the thumb is the stoutest of the digits.

Opposition and apposition[link]

A bonobo "fishing" for termites, an example of incomplete/"untrue" opposition.^[2]

In humans, opposition and apposition are two movements unique to the thumb but these words are not synonyms:

Primatologists and hand research pioneers J. Napier and P. Napier defined opposition as: "A movement by which the pulp surface of the thumb is placed squarely in contact with - or diametrically opposite to - the terminal pads of one or all of the remaining digits." For this true, pulp-to-pulp opposition to be possible, the thumb must rotate about its long axis (at the carpometacarpal joint).^[3] Arguably, this definition was chosen to underline what is unique to the human thumb.

Anatomists and other researchers focused exclusively on human anatomy, on the other hand, tend to elaborate this definition in various ways and, consequently, there are hundreds of definitions.^[4] Some anatomists^[5] restrict opposition to when the thumb is approximated to the fifth digit (little finger) and refer to other approximations between the thumb and other digits as apposition. To anatomists, this makes sense as two intrinsic hand muscles are named for this specific movement (the opponens pollicis and opponens digiti minimi respectively).

Other researchers use another definition,^[4] referring to opposition-apposition as the transition between flexion-abduction and extension-adduction; the side of the distal thumb phalanx thus approximated to the palm or the hand's radial side (side of index finger) during apposition and the pulp or "palmar" side of the distal thumb phalanx approximated to either the palm or other digits during opposition.

Moving a limb back to its neutral position is called reposition and a rotary movement is referred to as circumduction.

Human anatomy[link]

Skeleton[link]

The skeleton of the thumb consists of the first metacarpal bone which articulates proximally with the carpus at the carpometacarpal joint and distally with the proximal phalanx at the metacarpophalangeal joint. This latter bone articulates with the distal phalanx at the interphalangeal joint. Additionally, there are two sesamoid bones at the metacarpophalangeal joint.

Muscles[link]

The muscles of the thumb can be compared to guy-wires supporting a flagpole; tension from these musclular guy-wires must be provided in all directions to maintain stability in the articulated column formed by the bones of the thumb. Because this stability is actively maintained by muscles rather than by articular constraints, most muscles attached to the thumb tend to be active during most thumb motions.^[6]

The muscles acting on the thumb can be divided into two groups: The extrinsic hand muscles, with their muscle bellies located in the forearm, and the intrinsic hand muscles, with their muscles bellies located in the hand proper.^[7]

Extrinsic[link]

Flexor pollicis longus (left) and deep muscles of dorsal forearm (right)

A ventral forearm muscle, the flexor pollicis longus (FPL) originates on the anterior side of the radius distal to the radial tuberosity and from the interosseous membrane. It passes through the carpal tunnel in a separate tendon sheath, after which it lies between the heads of the flexor pollicis brevis. It finally attaches onto the base of the distal phalanx of the thumb. It is innervated by the anterior interosseus branch of the median nerve (C7-C8)^[8]

Three dorsal forearm muscles act on the thumb:

The abductor pollicis longus (APL) originates on the dorsal sides of both the ulna and the radius, and from the interosseous membrane. Passing through the first tendon compartment, it inserts to the base of the first metacarpal bone. A part of the tendon reaches the trapezium, while another fuses with the tendons of the extensor pollicis brevis and the abductor pollicis brevis. Except for abducting the hand, it flexes the hand towards the palm and abducts it radially. It is innervated by the deep branch of the radial nerve (C7-C8).^[9]

The extensor pollicis longus (EPL) originates on the dorsal side of the ulna and the interosseous membrane. Passing through the third tendon compartment, it is inserted onto the base of the distal phalanx of the thumb. It uses the dorsal tubercle on the lower extremity of the radius as a fulcrum to extend the thumb and also dorsiflexes and abducts the hand at the wrist. It is innervated by the deep branch of the radial nerve (C7-C8).^[9]

The extensor pollicis brevis (EPB) originates on the ulna distal to the abductor pollicis longus, from the interosseus membrane, and from the dorsal side of the radius. Passing through the first tendon compartment together with the abductor pollicis longus, it is attached to the base of the proximal phalanx of the thumb. It extends the thumb and, because of its close relationship to the long abductor, also abducts the thumb. It is innervated by the deep branch of the radial nerve (C7-T1).^[9]

The tendons of the extensor pollicis longus and extensor pollicis brevis form what is known as the anatomical snuff box (an indentation on the lateral aspect of the thumb at its base) The radial artery can be palpated anteriorly at the wrist(not in the snuffbox).

Intrinsic[link]

Thenar (left) and dorsal interossei (right) muscles

There are four thenar muscles:

The abductor pollicis brevis (APB) originates on the scaphoid tubercle and the flexor retinaculum. It inserts to the radial sesamoid bone and the proximal phalanx of the thumb. It is innervated by the median nerve (C8-T1).^[10]

The flexor pollicis brevis (FPB) has two heads. The superficial head arises on the flexor retinaculum, while the deep head originates on three carpal bones: the trapezium, trapezoid, and capitate. The muscle is inserted onto the radial sesamoid bone of the metacarpophalangeal joint. It acts to flex, adduct, and abduct the thumb, and is therefore also able to oppose the thumb. The superficial head is innervated by the median nerve, while the deep head is innervated by the ulnar nerve (C8-T1).^[10]

The adductor pollicis also has two heads. The transversal head originates along the entire third metacarpal bone, while the oblique head originates on the carpal bones proximal to the third metacarpal. The muscle is inserted onto the ulnar sesamoid bone of the metacarpophalangeal joint. It adducts the thumb, and assists in opposition and flexion. It is innervated by the deep branch of the ulnar nerve (C8-T1).^[10]

The opponens pollicis originates on the tubercle of the trapezium and the flexor retinaculum. It is inserted onto the radial side of the first metacarpal. It opposes the thumb and assists in adduction. It is innervated by the median nerve.^[10]

The first dorsal interosseous, one of the central muscles of the hand, extends from the base of the thumb metacarpal to the radial side of the proximal phalanx of the index finger.^[11]

Variation[link]

Hitchhiker's thumbs

"Hitchhiker's thumb" is an autosomal recessive trait more formally known as "distal hyperextensibility of the thumb".^[12] Homozygous carriers can extend the top of the thumb backwards nearly 90° when the thumb is extended in a "thumbs-up". Cases of Hitchhiker's thumb are subject to a variation in range of motion. Some who have this condition are able to hyperextend thumbs backwards 90° while still able to bend thumbs forward partially or with an added normal forward range of motion. Those with a more traditional case of Hitchhiker's thumbs can hyperextend backwards 90° while unable to bend past a straight position of the thumb.^[13] Malformations include a triphalangeal thumb and polydactyly.

Grips[link]

Left: In a power grip the object is in contact with the palm. Right: Cricketer Jack Iverson's "bent finger grip", an unusual pad-to-side precision grip designed to confuse batsmen.

One of the earlier significant contributors to the study of hand grips was orthopedic primatologist and paleoathropologist John Napier who proposed organizing the movements of the hand by their anatomical basis as opposed to work done earlier that had only used arbitrary classification.^[14] Most of this early work on hand grips had a pragmatic basis as it was intended to narrowly define compensable injuries to the hand, which required an understanding of the anatomical basis of hand movement. Napier proposed two primary prehensile grips: the precision grip and the power grip.^[15] The precision and power grip are defined by the position of the thumb and fingers where:

• The power grip is when the fingers (and sometimes palm) clamp down on an object with the thumb makes counter pressure. examples of the power grip are gripping a hammer, opening a jar using both your palm and fingers, and during pullups.
• The precision grip is when the intermediate and distal phalanges ("fingertips") and the thumb press against each other. Examples of a precision grip are writing with a pencil, opening a jar with the fingertips alone, and gripping a ball (only if the ball is not tight against the palm).

Opposability of the thumb should not be confused with a precision grip as some animals possess semi-opposable thumbs yet are known to have extensive precision grips (Tufted Capuchins for example).^[16] Nevertheless, precision grips are usually only found in higher apes, and only in degrees significantly more restricted than in humans.^[17]

Evolution[link]

The opposable thumb has helped the human species develop more accurate fine motor skills. It is also thought to have directly led to the development of tools, not just in humans or their evolutionary ancestors, but other primates as well. The opposable thumb ensured that important human functions such as writing were possible.^[18][19] The thumb, in conjunction with the other fingers, makes human hands and those of other species with similar hands some of the most dexterous in the world.^[20]

A primitive autonomization of the first carpometacarpal joint (CMC) may have occurred in dinosaurs. A real differentiation appeared perhaps 70 mya in early primates, while the shape of the human thumb CMC finally appears about 5 mya. The result of this evolutionary process is a human CMC joint positioned at 80° of pronation, 40 of abduction, and 50° of flexion in relation to an axis passing through the second and third CMC joints.^[21]

Opposable thumbs are shared by many primates, including most simians, and some prosimians. The climbing and suspensory behaviour in orthograde apes, such as chimpanzees, has resulted in elongated hands while the thumb has remained short. As a result, these primates are unable to perform the pad-to-pad grip associated with opposability. However, in pronograde monkeys such as baboons, an adaptation to a terrestrial lifestyle has led to reduced digit length and thus hand proportions similar to those of humans. Consequently, these primates have dexterous hands and are able to grasp objects using a pad-to-pad grip. It can thus be difficult to identify hand adaptations to manipulation-related tasks based solely on thumb proportions.^[22]

The evolution of the fully opposable thumb is usually associated with Homo habilis, the forerunner of Homo sapiens.^[23][24] This, however, is the suggested result of evolution from Homo erectus (around 1 mya) via a series of intermediate anthropoid stages, and is therefore a much more complicated link.

It is possible, though, that a more likely scenario may be that the specialized precision gripping hand (equipped with opposable thumb) of Homo habilis preceded walking, with the specialized adaptation of the spine, pelvis, and lower extremities preceding a more advanced hand. And, it is logical that a conservative, highly functional adaptation be followed by a series of more complex ones that complement it. With Homo habilis, an advanced grasping-capable hand was accompanied by facultative bipedalism, possibly implying, assuming a co-opted evolutionary relationship exists, that the latter resulted from the former as obligate bipedalism was yet to follow.^[25] Walking may have been a by-product of busy hands and not vice versa.

HACNS1 (also known as Human Accelerated Region 2) is a gene enhancer "that may have contributed to the evolution of the uniquely opposable human thumb, and possibly also modifications in the ankle or foot that allow humans to walk on two legs". Evidence to date shows that of the 110,000 gene enhancer sequences identified in the human genome, HACNS1 has undergone the most change during the human evolution since the chimpanzee-human last common ancestor.^[26]

Many animals also have some kind of opposable thumb or toe. An animal species is said to have opposable thumbs if the thumb is capable of bending in such a way that it can touch all the other digits on the hand. Most species do not have opposable thumbs. Opposable thumbs are a signature feature of the primate family, and played a large role in the ancient humans' invention and use of tools.

Primates

• Primates fall into one of four groups:^[27]
  • Nonopposable thumbs: tarsiers and marmosets
  • Pseudo-opposable thumbs: all strepsirrhines and Cebidae
  • Opposable thumbs: Old World monkeys and all great apes
  • Opposable with comparatively long thumbs: gibbons (or lesser apes)

Darwinius masillae, an Eocene primate fossil often described as a missing link between prosimian and simian, had hands and feet with highly flexible digits featuring opposable thumbs and halluces.^{[28][dubious – discuss][undue weight? – discuss]}

Other placental mammals

• Giant Pandas — five clawed fingers plus an extra-long sesamoid bone beside the true first digit that, though not a true digit, works like an opposable thumb.^[29]
• Lophiomys — a genus of African cricetid (rodent), with only one extant species (Lophiomys imhausi), but several extinct species, with opposable halluces.^[30]

Additionally, in many polydactyl cats, both the innermost and outermost ("pinky") toes may become opposable, allowing the cat to perform more complex tasks.

Marsupials

Left: Opposable digits of Sulawesi Bear Cuscus forelimb Right: Opposable thumb on rear foot of an opossum

• In most phalangerid marsupials (a family of possums) except species Trichosurus and Wyulda the first and second digits of the forefoot are opposable to the other three. In the hind foot, the first toe is clawless but opposable and provides firm grip on branches. The second and third toes are partly syndactylous, united by skin at the top joint while the two separate nails serve as hair combs. The fourth and fifth digits are the largest of the hind foot.^[31]
• Similar to phalangerids though in a different order, koalas have five digits on their fore and hind feet with sharp curved claws except for the first digit of the hind foot. The first and second digits of the forefeet are opposable to the other three, which enables the koala to grip smaller branches and search for fresh leaves in the outer canopy. Similar to the phalangerids, the second and third digits of the hind foot are fused but have separate claws.^[32]
• Opossums are New World marsupials with opposable thumbs in the hind feet giving these animals their characteristic grasping capability (with the exception of the Water Opossum, the webbed feet of which restrict opposability).^[33]
• The mouse-like microbiotheres were a group of South American marsupials most closely related to Australian marsupials. The only extant member, Dromiciops gliroides, is not closely related to opossums but has paws similar to these animals, each having opposable toes adapted for gripping.^[34]

Reptiles

• Troodon — a birdlike dinosaur — partially opposable thumbs.
• Bambiraptor — a small, predatory dinosaur — it could touch the outer two of its three digits together in an opposable grip.
• Nqwebasaurus — a coelurosaur with a long, three-fingered hand which included a partially opposable thumb (a "killer claw").^[35]

Most birds have at least one opposable digit on the foot, in various configurations, but these are seldom called "thumbs".

Amphibians

• Phyllomedusa, a genus of frogs native to South America.^[36]

Carlos Irwin Estevez (born September 3, 1965), better known by his stage name Charlie Sheen, is an American film and television actor. He is the youngest son of actor Martin Sheen.

His character roles in films have included Chris Taylor in the 1986 Vietnam War drama Platoon, Jake Kesey in the 1986 film The Wraith, and Bud Fox in the 1987 film Wall Street. His career has also included more comedic films such as Major League, the Hot Shots! films, and Scary Movie 3 and Scary Movie 4. On television, Sheen is known for his roles on two sitcoms: as Charlie Crawford on Spin City and as Charlie Harper on Two and a Half Men. In 2010, Sheen was the highest paid actor on television, earning US$1.8 million per episode of Two and a Half Men.^[3]

Sheen's personal life has also made headlines, including reports about alcohol and drug abuse and marital problems as well as allegations of domestic violence. He was fired from his role on Two and a Half Men by CBS and Warner Bros. on March 7, 2011. Sheen subsequently announced a nationwide tour.^[4]

Early life[link]

Sheen was born Carlos Irwin Estevez in New York City, the youngest son and third of four children of actor Martin Sheen and artist Janet Templeton.^[5] His paternal grandparents were immigrants from Galicia (northwestern Spain) and Ireland.^[6] Sheen has two older brothers, Emilio Estevez and Ramon Estevez, and a younger sister, Renée Estevez, all actors. His parents moved to Malibu, California, after Martin's Broadway turn in The Subject Was Roses. Sheen's first movie appearance was at age nine in his father’s 1974 film The Execution of Private Slovik. Sheen attended Santa Monica High School in Santa Monica, California, where he was a star pitcher and shortstop for the baseball team.^[5][7]

At Santa Monica High School, he showed an early interest in acting, making amateur Super 8 films with his brother Emilio and school friends Rob Lowe and Sean Penn under his birth name. A few weeks before graduation, Sheen was expelled from school for poor grades and attendance. Deciding to become an actor, he took the stage name Charlie Sheen. His father had adopted it in honor of the Catholic archbishop and theologian Fulton J. Sheen.^[8][9]

Acting career[link]

Film[link]

Sheen's film career began in 1984 with a role in the Cold War teen drama Red Dawn with Patrick Swayze, C. Thomas Howell, Lea Thompson, and Jennifer Grey. Sheen and Grey reunited in a small scene in Ferris Bueller's Day Off (1986). He also appeared in an episode of the anthology series Amazing Stories. Sheen had his first major role in the Vietnam War drama Platoon (1986). In 1987, he starred with his father in Wall Street. Both Wall Street and Platoon were directed by Oliver Stone. In 1988, Stone asked Sheen to star in his new film Born on the Fourth of July (1989), but later cast Tom Cruise instead. Sheen was never notified by Stone, and only found out when he heard the news from his brother Emilio. Sheen did not take a lead role in Stone's subsequent films,^[10] although he did have a cameo role in Money Never Sleeps.

In 1987, Sheen was cast to portray Ron in the unreleased Grizzly II: The Predator, the sequel to the 1976 low budget horror movie Grizzly. In 1988, he starred in the baseball film Eight Men Out as outfielder Happy Felsch. Also in 1988, he appeared opposite his brother Emilio in Young Guns and again in 1990 in Men at Work. In 1989, Sheen, John Fusco, Christopher Cain, Lou Diamond Phillips, Emilio Estévez and Kiefer Sutherland were honored with a Bronze Wrangler for their work on the film Young Guns.^[11]

In 1990, he starred alongside his father in Cadence as a rebellious inmate in a military stockade and with Clint Eastwood in the buddy cop action film The Rookie.^[5] The films were directed by Martin Sheen and Eastwood, respectively. In 1992, he starred in Beyond the Law with Linda Fiorentino and Michael Madsen. In 1994, Sheen was awarded a star on the Hollywood Walk of Fame.^[11] In 1997, Sheen wrote his first movie, Discovery Mars, a direct-to-video documentary revolving around the question, "Is There Life on Mars?". The next year, Sheen wrote, produced and starred in the action movie No Code of Conduct.^[12]

Sheen appeared in several comedy roles, including the Major League films, Money Talks, and the spoof Hot Shots! films. In 1999, Sheen appeared in a pilot for A&E Network, called Sugar Hill, which was not picked up. In 1999, Sheen played himself in Being John Malkovich. He also appeared in the spoof series Scary Movie 3 and follow up Scary Movie 4.

Sheen appears as Dex Dogtective in the unreleased Lionsgate animated comedy Foodfight.^[12]

Sheen has been cast to star alongside Jason Schwartzman in Roman Coppola's upcoming film A Glimpse Inside the Mind of Charlie Swan III.^[13]

Television[link]

In 2000, Sheen debuted on the small screen when he replaced Michael J. Fox for the last two seasons of the sitcom Spin City. For his work on Spin City, Sheen was nominated for two ALMA Awards and won his first Golden Globe for Best Performance by an Actor in a Television Series – Musical or Comedy.^[14][15] The series ended in 2002.

In 2003, Sheen was cast as Charlie Harper in the CBS sitcom Two and a Half Men, which followed the popular Monday night time slot of Everybody Loves Raymond. Sheen's role on Two and a Half Men was loosely based on Sheen's bad boy image.^[16] The role garnered him an ALMA Award and he gained three Emmy Award nominations and two Golden Globe award nominations.^[14] During his eighth and final season on the show, Sheen earned a record $1.8 million per episode.^[3]

Warner Bros. dismissal[link]

In January 2011, production of Two and a Half Men went on hiatus while Sheen underwent a substance rehabilitation program in his home, his third attempt at rehab in twelve months.^[17][18][19] The following month, however, CBS canceled the season's four remaining episodes after Sheen publicly made derogatory comments about the series' creator, Chuck Lorre,^[20] and Warner Bros. officially banned Sheen from entering its production lot.^[21] Sheen, already the highest-paid actor on television,^[3] responded by publicly demanding a 50 percent raise,^[22] claiming that in comparison to the amount that the series was making, he was "underpaid."^[22]

CBS and Warner Bros. fired Sheen from Two and a Half Men on March 7, 2011.^[23] He was replaced by Ashton Kutcher.^[24][25] In the aftermath of his dismissal, Sheen remained vocally critical of Chuck Lorre,^[26] and filed a wrongful termination lawsuit against Lorre and Warner Bros., which was settled the following September 26.^[27] That same month, Sheen, while presenting an award at the Primetime Emmy Awards, addressed "everybody here from Two and a Half Men" and stated, "From the bottom of my heart, I wish you nothing but the best for this upcoming season. We spent eight wonderful years together and I know you will continue to make great television."^[28]

Meltdown[link]

This section requires expansion.

In the wake of the dismissal, Sheen had a highly publicized "meltdown" which was broadcast on television and the internet. He made bizarre statements in television interviews, suggesting that he was a "warlock" with "tiger blood" and "Adonis DNA".^[29] He also posted videos to YouTube showing himself smoking cigarettes through his nose, and cursing out his former employers. ^[30] He told one TV interviewer, "‘I’m tired of pretending I’m not special. I’m tired of pretending I’m not a total bitchin’ rock star from Mars."^[31]

Other[link]

On September 19, 2011, Sheen was roasted on Comedy Central. It was watched by 6.4 million people, making it the highest rated roast on Comedy Central to date.^[32]

Other ventures[link]

In 2006, Sheen launched a clothing line for kids, called Sheen Kidz.^[33]

In 2011, Sheen set a new Guinness World Record for Twitter as the "Fastest Time to Reach 1 Million Followers" (adding an average of 129,000 new followers per day^[34]) as well as the Guinness record for "Highest Paid TV Actor Per Episode – Current" at $1.25 million while he was a part of the cast of Two and a Half Men sitcom.^[35] On March 3, 2011, Charlie Sheen signed with Ad.ly marketing agency specializing in Twitter and Facebook promotions.^[36][37]

Sheen's "My Violent Torpedo of Truth/Defeat is Not An Option" tour on the marquee of Radio City Music Hall in New York City.

On March 10, 2011, Sheen announced a nationwide tour, "My Violent Torpedo of Truth/Defeat is Not An Option", which began in Detroit on April 2.^[38] The tour sold out in 18 minutes, a Ticketmaster record.^[39] However, on April 1, 2011 the Detroit Free Press featured an article that stated as of March 30 that there were over 1000 tickets available from a third-party reseller, some at 15% less than the cheapest seats sold at the Fox Theater.^[40] The Huffington Post reported that it was expected Sheen would earn $1 million in 2011 from Twitter endorsements and $7 million from the North American tour.^[41] Many of those attending the April 2 performance in Detroit found it disappointing;^[42] the subsequent performance in Chicago, which featured some adjustments, received a more positive reception.^[43]

Sheen has taken up a new business venture as a partner in a line of electronic cigarettes. The "NicoSheen" product will feature the actor's signature smirk on packages of disposable E-cigarettes and related products.^[44]

On August 13, 2011, Sheen appeared as a host at the 12th annual Gathering of the Juggalos. He received a mixed reaction from the audience. Some cheered him, and some booed and threw things at him.^[45]

Personal life[link]

Family and relationships[link]

Sheen has been married three times and has five children. His first daughter, Cassandra Jade Estevez, was born on December 12, 1984, to his former high school girlfriend, Paula Profit.^[46][47]

In January 1990, Sheen accidentally shot his fiancee, Kelly Preston, in the arm.^[48] She broke off the engagement soon after.^[49][50][51]

In the 1990s, Sheen dated a number of adult film actresses, including Ginger Lynn^[48][52][53] and Heather Hunter.^[48]

On September 3, 1995,^[54] Sheen married Donna Peele.^[55] That same year, Sheen was named as one of the clients of an escort agency operated by Heidi Fleiss.^[56] Sheen and Peele divorced in 1996.^[5]

On June 15, 2002, Sheen married actress Denise Richards. They have two daughters, Sam^[57] and Lola Sheen.^[58] In March 2005, Richards filed for divorce, accusing Sheen of alcohol and drug abuse and threats of violence.^[59] The divorce was finalized in November 2006 and preceded a custody dispute over their two daughters.^[60][61][62]

On May 30, 2008, Sheen married Brooke Mueller, who later gave birth to their twin sons, Bob and Max.^[63][64][65] In November 2010, Sheen filed for divorce. On March 1, 2011, police removed Bob and Max from Sheen's home. Sheen told NBC's Today, "I stayed very calm and focused."^[66] According to People, social services took the children after Mueller obtained a restraining order against Sheen. The document said, "I am very concerned that [Sheen] is currently insane."^[67] Asked if he would fight for the children, Sheen texted People, "Born ready. Winning."^[67] Sheen and Mueller's divorce became final on May 2, 2011.^[2][68][69]

On March 1, 2011, Sheen was concurrently living with pornographic actress Rachel Oberlin and model and graphic designer Natalie Kenly, whom he collectively nicknamed his "goddesses".^{[70][71][72][73][74]} Oberlin left Sheen in April 2011, and Kenly left in June 2011.^[75][76]

Substance abuse and legal issues[link]

On May 20, 1998, Sheen overdosed while using cocaine and was hospitalized. On August 11, 1998, Sheen, already on probation for a previous drug offense, had his probation extended for an extra year and entered a rehab clinic.^[77][78] In a 2004 interview, Sheen admitted that the overdose was caused by his experimentation with injecting cocaine.^[79]
