Finger Joint Fusions
Hand, Wrist & Finger Specialist Care
Finger joint fusion is a surgical procedure performed to treat severe arthritis or joint instability in the fingers. This technique involves permanently joining two or more bones together, eliminating the painful joint movement. Fusion is often considered when conservative treatments fail to provide relief, and the patient experiences chronic pain and functional limitations.
Indications
Finger joint fusions are recommended for individuals with the following conditions:
Advanced arthritis: Severe degeneration of the joint cartilage leading to pain, swelling, and stiffness.
Joint instability: Significant joint instability due to ligament damage or joint deformities.
Failed previous treatments: When other conservative treatments, such as medications, splints, or injections, do not provide satisfactory results.
Joints that can benefit from fusion
Finger joint fusions are commonly performed on the following joints:
Distal interphalangeal joints (DIPJs): The DIPJ is the most frequent joint to benefit from fusion, especially when large osteophytes (bumps) around the joint cause significant discomfort.
Proximal interphalangeal joints (PIPJs): The PIPJ can be fused or replaced, depending on the severity of symptoms and arthritis.
Types of fusion
Finger joint fusions are typically achieved using a screw that goes inside the bone to hold the bones together. For the PIPJ, a specialised screw-in-screw system may be used to decrease the burden of visible metalware that can be seen when using a plate. This technique provides stability and promotes bony union at the fused joint.
Rehabilitation
After finger joint fusion, rehabilitation is a crucial part of the recovery process and may include:
Immobilisation with a splint: Initially, the fused finger joint will be immobilised with a splint to protect the healing bones.
Outcome
Studies have shown a high rate of successful outcomes following finger joint fusions. According to patient-reported outcomes, up to 95% of individuals achieve excellent or good results, experiencing reduced pain and improved hand function after the procedure.
