The structures that make the fingers move are called tendons. There are tendons on both sides of the hand. Those that straighten the fingers are known as the extensors and those that bend the fingers are the flexors.
Sometimes as a result of injury or disease these tendons can rupture or break. This results in an inability to fully move the digit or hand.
Tendon repairs are important to try and restore function. Postoperative rehabilitation with specialist hand therapists is especially important in achieving maximum restoration of function following injury and surgical repair.
Depending on the cause, site, severity and level of the injury, the regime and period of splintage varies. If postoperative regimes are not rigorously followed there is a significant risk of re-rupture and stiffness.
