Wrist

In human anatomy, the wrist is variously defined as 1) the carpus or carpal bones, the complex of eight bones forming the proximal skeletal segment of the hand; (2) the wrist joint or radiocarpal joint, the joint between the radius and the carpus; and (3) the anatomical region surrounding the carpus including the distal parts of the bones of the forearm and the proximal parts of the metacarpus or five metacarpal bones and the series of joints between these bones, thus referred to as wrist joints. This region also includes the carpal tunnel, the anatomical snuff box, the flexor retinaculum, and the extensor retinaculum.

As a consequence of these various definitions, fractures to the carpal bones are referred to as carpal fractures, while fractures such as distal radius fracture are often considered fractures to the wrist.

Structure

The distal radioulnar joint is a pivot joint located between the bones of the forearm, the radius and ulna. Formed by the head of ulna and the ulnar notch of radius, this joint is separated from the radiocarpal joint by an articular disk lying between the radius and the styloid process of ulna. The capsule of the joint is lax and extends from the inferior sacciform recess to the ulnar shaft. Together with the proximal radioulnar joint, the distal radioulnar joint permits pronation and supination.

Chris Brown

Christopher Maurice "Chris" Brown (born May 5, 1989) is an American singer, dancer, rapper and actor. Born in Tappahannock, Virginia, he was involved in his church choir and several local talent shows from a young age. Having signed with Jive Records in 2004, Brown released his self-titled debut studio album the following year. It peaked at number two on the US Billboard 200 and was later certified double platinum by the Recording Industry Association of America (RIAA). With his first single "Run It!" peaking atop the US Billboard Hot 100, Brown became the first male artist as a lead since Diddy in 1997 to have his debut single top the chart. His second album Exclusive (2007) spawned his second Hot 100 number one "Kiss Kiss", in addition to "With You" and "Forever". The album was also certified double platinum by the RIAA.

In 2009, Brown received much media attention after pleading guilty to felony assault of his then girlfriend, singer Rihanna; he was sentenced to five years of probation and six months of community service. His third album Graffiti was released later that year, and included the top-twenty single "I Can Transform Ya". Brown's fourth album F.A.M.E. (2011) became his first to top the Billboard 200; it spawned the successful singles "Yeah 3x", "Look at Me Now", and "Beautiful People". F.A.M.E. earned Brown his first Grammy Award for Best R&B Album at the 54th Grammy Awards. His fifth album Fortune was released in 2012. However, after the release of Exclusive, Brown's albums have not been well received commercially or by music critics, with the exception of X, which received a normalized rating of 63. Brown's seventh studio album Royalty was released on December 18, 2015.
