A mallet finger is a reduced or absent extension function at the level of the end joint of the finger (DIP joint). It occurs when the finger is accidentally bent abruptly when it was actually extended. As a result, there is an inability to extend the last phalanx. This can have two causes:
Complaints in a mallet finger
In both cases, the consequence is the same; the end joint of the finger starts to droop and can no longer be actively stretched. At first, the finger is usually painful and swollen around the end joint.
In principle, this condition can be treated well with a mallet splint or thermoplastic splint. This involves splinting the fingertip, while leaving the second joint of the finger free to bend and stretch so that it remains flexible. It is essential that this mallet splint is worn 24 hours a day and not simply taken off.
You can take care of the finger yourself daily. When showering, it is advisable to keep the splint on. When grooming, it is very important not to bend the finger. After showering, lay the finger flat on a firm surface, e.g. a table. With the tip of the finger, press on the table to keep the finger straight. This will allow it to dry, once the finger is dry, you can slide the splint back on and fix it with tape if necessary.
If you remove the splint and bend the finger, the healing process starts all over again!
In rare cases, surgery is necessary despite this intensive therapy. When this is the case, it will be discussed by your treated (plastic) surgeon.
