A thumb sprain happens when you injure the tissues in your thumb that connect the bones in a joint. These tissues, known as ligaments, keep your bones in place when the joint moves. In your thumb, several ligaments help you grab objects, pinch, and make a fist.
Many times, thumb sprains will result from sports injuries or falls. For example, skiing results in many thumb injuries, as does basketball. Or, you may fall and try to catch yourself, bending your thumb in an awkward position.
Injuries to the hand and fingers are common in sports and must be taken seriously. If not treated properly, they can be very debilitating and have long-term consequences. Here we explain sudden onset acute injuries as well as chronic overuse hand and finger injuries.
Everyone has had a minor problem with a finger, hand, or wrist. Most of the time our body movements do not cause problems, but it's not surprising that symptoms occur from everyday wear and tear or from overuse. Finger, hand, or wrist problems can also be caused by injuries or the natural process of aging.
Texting, typing, gaming … Such activities pervade our lives. More specifically these painful or irritating conditions are repetitive stress injuries that fall under the more scientific categories of tendinitis, tendinosis, carpal tunnel syndrome, osteoarthritis, carpometacarpal joint irritation, collateral ligament injury, etc. As I alluded to, we use our thumbs frequently throughout the day for technology use and otherwise.
Jonathan Croswell has spent more than five years writing and editing for a number of newspapers and online publications, including the "Omaha World-Herald" and "New York Newsday. There are 27 bones in the hand and wrist, and these moving parts are joined by tendons and ligaments in the normal functioning of this body part. Because many of these bones and other moving parts are interrelated, it can sometimes be difficult to identify the location of the damage.
The bones in a normal hand line up precisely, letting you perform many specialized functions like grasping a pen or manipulating small objects in your palm. When you fracture a finger bone, it can put your whole hand out of alignment. Without treatment, your broken finger may stay stiff and painful.
A sprained thumb occurs when the ligaments that support the thumb stretch beyond their limits or tear. This usually happens when a strong force bends the thumb backwards, away from the palm of the hand. The most common way for this to occur is by falling onto an outstretched hand. A tear to this ligament can be painful and may make your thumb feel unstable.
