Wrist pain is common. Repetitive motion can damage your wrist. Everyday activities like typing, racquet sports or sewing can cause pain, or even carpal tunnel syndrome. Wrist pain with bruising and swelling can be a sign of injury. The signs of a possible fracture include misshapen joints and inability to move your wrist. Some wrist fractures are a result of osteoporosis.
A sprain is an injury to a ligament. Ligaments are the connective tissues that connect bones to bones; they could be thought of as tape that holds the bones together at a joint.
The most common ligament to be injured in the wrist is the scapho-lunate ligament. It is the ligament between two of the small bones in the wrist, the scaphoid bone and the lunate bone. There are many other ligaments in the wrist, but they are less frequently injured. Sprains can have a wide range of severity; minor sprains may have minimal stretch of the ligaments, and more severe sprains may represent complete tears of the ligament(s). Another common ligament injured is the TFCC (triangular fibrocartilage complex).
