If your finger bends at all, it can set back the healing process. Any straight, solid item will work as a splint so long as it is strong enough to hold the finger in place. It is also imperative that the tape is wrapped around tightly so that you do not have enough mobility to bend your finger, but not so tight that you cut off circulation or cause the finger to become numb or discolored.
In rare instances where wearing a splint would seriously impede your work — if you were a surgeon for example — it is possible to have a pin inserted into your finger to keep it straight.
It can be especially tempting to remove your splint while showering. One of the advantages of the Oval 8 splint is that it can get wet. If you are using a different splint, put your finger in a plastic bag or use a glove.
Approximately ten days after surgery you will meet back up with your doctor to remove the sutures and monitor the progress of the healing.
