What is Sprained Finger?
The sprained finger is common in sports with the most common being finger sprain. Each finger has three small bones called “phalanges” separated by two interphalangeal joints. The thumb only has one interphalangeal joint and two small phalange bones. The sprain is an injury to a ligament that runs along each side of the joints. Also, you cannot bend finger and usually need a splint. In other words, the ligaments of the side of the finger get damaged.
