In most people, the ulna is shorter than the the radius. In a small percentage of individuals, the ulna is longer than the radius. This is known as ulna plus variance. There is an a association with various injuries, such as those to the TFCC, but generally nothing is done unless problems develop.
Slighty mistake on my part...MRI report says mild ulnar plus variance, not mild plus variance.
I forgot to add.. with the mild ulnar plus variance should I be seeing a specialist? I've had problems with my wrist for the past year. Thanks!
The TFCC is a ligament? So if it's torn or injured does that cause the ulna to be longer than the radius? The bone slips into a higher position, caused it to be longer? Or can fractures, even if not severe. cause this?
I've had numerous injuries to my wrist and hand that were never treated in the past. Only the past 1-2 years I've experienced problems with pain, clicking or clunking.
Thanks for your help!
The TFCC includes cartilage, tendons, and ligaments. The ulna plus variance is not the result of an injury, it is a normal variant of anatomy that predisposes you to wrist injuries. If you are having recurrent injuries, then evaluation by a hand specialist might be a good idea.
