What are hand ligaments?
Ligaments are tough pieces of connective tissue that join one bone to another. Ligaments are attached on either side of a joint, strengthening and stabilizing it by limiting excess motion of the bones. Injuries to ligaments are very common; in fact, what we call a sprain is actually an injury to the ligaments of the “sprained” joint. The hand is particularly susceptible to ligament injuries simply because it gets so much use and thus is exposed to many possibilities for injury. One common place for a hand ligament injury to occur is in the scapholunate ligament. This ligament connects the scaphoid and the lunate, two of the small carpal bones, which make up the wrist and base of the palm.
