Finger Joint Replacements
Finger joint replacement surgery is performed to improve the symptoms of pain in degenerate joints. The joints are most often damaged as a result of osteoarthritis (wear and tear), previous severe injury or rheumatoid arthritis. This can lead to stiffness, pain and deformity of the hands and fingers. Unfortunately, many people are unaware that these conditions are able to be corrected and live with significant pain and deformity of their hands. In much same way that both hip and knee joints can be replaced with artificial joints, so can the joints of the hand and fingers. Outcome following finger joint replacement is however slightly different. The aim of finger joint replacement surgery is to improve symptoms of pain. It is important to stress that the range of motion of the finger may not improve.

Which joints can be replaced?
The option of which implant is suitable will also depend on which finger joint is affected.

The MCP joints are the main knuckle joints between your hand and finger. These joint are very important in making a fist. They are commonly affected by rheumatoid arthritis but also by osteoarthritis. The use of either silicone (rubber) type implants or a pyrocarbon implant will likely be discussed with you.
Proximal interphalangeal joint (PIPJ):
The PIP joints are the middle knuckle joints in the fingers. They are crucial in gripping and also in the fine control of the fingers. Options for replacement surgery here will include surface replacement (very much like a tiny knee replacement) or silicone type implants. The relative merits of each will be discussed with you at your consultation.
Distal Interphalangeal joints (DIPJ):
These are the joints that are closest to the end of your fingers. They are often affected by osteoarthritis. Joint replacements are not commonly utilised here with fusion of the joint providing excellent pain relief and stability to the end of the finger.
Is the operation undertaken as a day case?
What outcome can I expect?
Finger joint replacement surgery is primarily performed to improve symptoms of pain. It can also improve the appearance and restore the alignment of the fingers. Improving the amount that the fingers bend following the surgery is less predictable. The scientific evidence supports the fact that most patients will have either the same or slightly less movement following a joint replacement, but some patients will have more. Satisfaction from the operation is often reported in relation to the dramatic improvement in symptoms of pain however. The prostheses do wear over time and on occasions patients may need to have revision surgery. This is more likely in younger patients or patients involved with heavier or repetitive use of the hands. You will be advised to protect the hands where possible with this in mind.
