Splinting is the first-line treatment for a mallet finger. The goal is to keep the fingertip straight in the splint until the tendon heals. Finger will stay in a splint for at least six weeks. After that, you’ll wear the splint only at night for another two weeks. You may be advised to wear your splint for other high-risk activities, such as manual work or sports, during those two weeks.
Exercise
hold your hand to support the middle joint on either side.
Bend that joint, keeping the splinted part of your finger straight.
Do this 10 times, 4 to 5 times a day.
Use your other hand to hold down (block) the middle joint of the injured finger.
Bend only the last joint down for a count of 10 and then straighten it for a count of 10.
Do this 2 to 3 times a day, for 5 minutes. This is to help regain flexion and to strengthen the tendon.
