There are two types of operation which are helpful for arthritic fingers: Fusing the joint (arthrodesis) or joint replacement (arthroplasty). These are day case operations which can usually be done by ‘awake surgery’ using local anaesthetic. It could be that some patients will have more than one finger joint replacement in a single operation. A small incision is made in the finger, the damaged joint is removed and the artificial joint is inserted. The artificial joint is made of silicone plastic, metal or ceramic. It functions in the same way as a healthy joint, a bit like a hinge on a door, although the movement is typically about half the range in a healthy joint. Alternatively, fusing the joint means that it is set in a fixed position and no further movement is possible. Both types of operation reliably remove the pain from arthritis but of course have different results regarding the freedom of movement in the hand.
After surgery, some hand physiotherapy is necessary for several weeks and protective splints are often required during this period but typically these may be removed at times to do light activities as well as physiotherapy exercises. After about 8-10 weeks patients should be able to resume usual activities including golf, tennis and gardening, for example.
