10/30/2023 0 Comments How long is your thumbSprained thumb is usually the result of a repetitive activity that puts excessive pressure on the thumb joints, forcing the thumb to move beyond its movement range. These thumb joints come under heavy pressure when the thumb is stretched or compressed during any task and when such pressure is applied repetitively, the cartilage or the connective tissues sometimes get damaged resulting in a joint injury known as sprained thumb. The connective tissues and cartilage between these joints ensure that there is enough cushioning during thumb movement when bone collides with bone. The thumb comprises of two joints with the IP (Interphalangeal) joint lying between the two phalanges and the MCP (Metacarpophalangeal) joint lying between the first metacarpal and the lower phalange. Sprained thumb is a condition related to the joints and connective tissues that help in thumb movement.
