If you follow the NFL, then you know that the Bears All Pro linebacker, Brian Urlacher, dislocated his "wrist" Sunday night against the Packers and will be out the remainder of the season after undergoing surgery yesterday. The term "wrist" only describes a general area of the body, and the exact bone that was dislocated was not disclosed in any of the press releases. The actual "wrist" is the articulation of the distal end of the radius with the proximal row of carpal bones (four bones). The most commonly dislocated carpal bone is the lunate, which is located almost directly beneath the middle finger. This bone helps hold the wrist together, and often times when it is dislocated, it must be put back into place with pins via surgery. This type of surgery requires a lengthy recovery. I was able to do some digging and Urlacher did, in fact, dislocate the lunate.
