The hand and wrist are a complicated system of bones, muscles, ligaments and cartilages that can work both independently and separately from each other. What affects one can affect the whole wrist. Wrist stability can be impacted at any level and is most commonly caused by a previous injury or condition that damages the ligaments and tendons in the hand. As this often affects the carpal bones in one way or another, complex instabilities are generally known as carpal instabilities and can impact on the stability of the wrist and make everyday tasks a challenge. The level of instability determines the course of action that must be undertaken to correct this.
