Capsule injury
A capsule injury in the finger often occurs as a result of overstretching or forcible extension of the affected finger joint. In many cases, ball sports such as volleyball or handball are possible causes. The affected finger bends away and, in addition to the tear in the joint capsule, an injury to the stabilizing ligamentous apparatus of the finger occurs.
This results in severe pain and considerable swelling of the finger and joint. The swelling develops due to the fluid that escapes from the damaged joint capsule. Bruising around the joint or in the area of the finger may also develop as a result of the injury.
Therapeutically, the finger joint should be cooled immediately and immobilized with the help of a splint for about two weeks so that the damaged joint capsule on the finger can regenerate. Complete healing can take up to six weeks. In some cases, the capsule injury may not heal properly and lead to osteoarthritis in the affected finger joint.
