Ligament damage in fingers is often caused by trauma from sports or falls, leading to sprains or dislocations. Playing ball sports can cause jamming and hyperextension, while falls can strain or tear ligaments connecting palms and fingers. Dislocations can also stretch or tear ligaments, sometimes requiring surgery.
Ligament damage in the fingers, in which the tissue that connects the bones of the finger joints is strained or torn, is usually the result of trauma to the hand. Sprains are often the result of participating in sports such as football or basketball where the hands are heavily used and the fingers tend to jam. A fall that lands a person on their hand can hyperextend the hand backwards, damaging the ligaments between the palm and fingers. These and other types of blows to the hand can also cause dislocation, in which joints are forcibly displaced out of their normal positions, which typically damages the ligaments there.
One of the most common causes of ligament damage in the fingers is playing sports, especially those that involve handling, passing, and catching a ball such as basketball, football, or baseball. If the ball is mishandled or hits the hand unexpectedly, the fingers may jam which means that there is trauma to the fingers which then puts strain on the ligaments. This can lead to a sprain, a condition in which the ligament is stretched further than it can naturally go. In severe cases, the ligament may even be torn partially or completely.
Another common reason for ligament damage in the fingers is falling. When a person falls, he can instinctively reach out to stop him. If the person lands hands down, he may be pushed backwards, hyperextending and thereby straining or tearing the ligaments joining the palms to the fingers. Of course, the person can also land in other ways which can jam the fingers and also cause damage to the ligaments in the fingers.
It is also possible to cause ligament damage in the fingers by dislocating any of the joints in the fingers. Joint dislocation can occur while playing sports or during a fall, but it can also be the result of other types of trauma such as a blow to the hand or something heavy falling on the fingers. When a dislocation occurs, a bone is pulled away from where it usually sits next to another bone, which means that the ligament attaching them is stretched or perhaps torn. In some cases, it can also cause an avulsion fracture, where a piece of bone is torn off when the ligament is pulled away. The ligament often remains injured even after the dislocation is corrected and usually requires additional treatment, possibly including surgery.
