Tendons allow our finger joints to straighten and to close like a fist. Any disruption to this system may stop or limit these movements. The two broad categories of tendon injury are closed and open injuries. Open injuries imply a laceration of some sort and usually require surgical exploration.
Closed tendon injuries, in some areas of the body, can be managed non-operatively with splints and rehabilitation. Some closed tendon injuries, especially those that cause the finger tips to bend, may require surgical treatment.
