Why is the tendon so important in pointing a finger?
The extensor tendon is what works to allow you to extend your hand and fingers. Without them working properly, you would not be able to flatten you hand out or point your fingers. There are many ways the extensor tendons can become damaged, and if they are not treated properly, you could be left with a long-term inability to use your fingers to their fullest potential.
