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.

Young Jeezy

Jay Wayne Jenkins (born September 28, 1977), better known by his stage name Young Jeezy (or simply Jeezy), is an American hip-hop recording artist from Atlanta, Georgia. In 1998, he launched the label imprint CTE World (then known as Corporate Thugz Entertainment). Aside from his solo career, Jeezy is the de facto leader of the southern hip hop group United Streets Dopeboyz of America (USDA), and is a former member of Bad Boy Records' Boyz n da Hood. Jeezy is also known for helping pioneer the hip hop subgenre trap music, alongside fellow Atlanta-based rapper T.I..

Jeezy embarked on his music career in 2001, as Lil J, with the release of Thuggin' Under the Influence (T.U.I.). He later joined Boyz n da Hood in 2005, the same year his solo major label debut Let's Get It: Thug Motivation 101, was released. Its lead single "Soul Survivor", which features R&B singer Akon, became a top-ten hit in the US. His subsequent albums, The Inspiration (2006) and The Recession (2008), both yielded chart-topping singles. Jeezy has also been featured on numerous hip-hop and R&B hit singles, such as "Say I" by Christina Milian, "I'm So Paid" by Akon, "Hard" by Rihanna and "Love in This Club" by Usher, the latter of which reached number one on the US Billboard Hot 100, in 2008.
