This article is going to tell you exactly why Brian Urlacher needs surgery on a dislocated wrist. Many people think that since it's just a dislocation, that all he had to do was pop it back into place. WRONG!The wrist is probably the worst place to get a dislocation. The wrist has so many tiny bones and tendons, that with the speed and strength he delivered in that tackle, it probably severely toar mostly all of the tendons, and knocked the bones out of place. Here is exactly what doctors say a dislocated wrist is:
The wrist joint is composed of distal radial and ulnar surfaces, 8 carpal bones, and the proximal metacarpal bones. The distal carpal row consists of the following bones: hamate, capitate, trapezoid, and trapezium. The proximal row consists of the following bones: scaphoid, lunate, triquetrum, and pisiform.
The carpal bones are held together by a complex set of ligaments, including the interosseous, volar, and dorsal ligaments and a triangular fibrocartilage complex (TFC).The dorsal ligaments are weaker than the volar ligaments, making dorsal dislocation more common.
A person with a wrist dislocation has a bone that has come out of place in the wrist joint. A wrist dislocation usually occurs with a wrist fracture.

Now most people are saying that why can't he wear a club cast; he can't do that because the wrist is so gentle that the wrist will have to be under close supervision. The bones could nudge up against a piece of foam and get nudged out of place. This injury is more serious than people are thinking it is. If he plays on it, he can make it worse, maybe to the point where the wrist wouldn't operate in a normal function.
Hopefully this clears up the reason why Brian Urlacher is having surgery on a dislocated wrist. If you have any questions, leave a comment and I'll try to answer it as soon as possible.
