Joint Fusion Surgery

Joint fusion surgery joins the bones across a damaged joint to reduce painful movement and improve stability.

Also called arthrodesis, it removes damaged joint surfaces and holds the adjoining bones in a planned position while they grow together. The operation aims to reduce pain from movement, but that joint will no longer bend normally. It is used in selected areas such as the ankle, big toe, hand, or thumb.

Recovery usually starts with protection in a splint, cast, or boot. The operated area may need to stay raised, and weight or hand use is increased only according to the surgical plan. Follow-up visits and imaging help the team check alignment and bone healing. Physiotherapy may then address strength, walking pattern, balance, or safe hand function.

Possible problems include infection, a blood clot, nerve irritation, wound difficulty, hardware discomfort, altered movement in nearby joints, or bones that heal slowly or fail to join. Risk varies with the joint, general health, smoking, bone quality, and the operation. Contact the surgical team for worsening redness, drainage, fever, severe swelling, or new pain rather than waiting for a routine visit.

Fusion can reduce pain that comes from the treated joint moving, and its stability is intended to last once the bones have united. It cannot restore movement at that joint, and nearby joints may take on more work over time. The result depends on the original damage, bone healing, alignment, and rehabilitation.

The aim is a solid, well-aligned union rather than preserving joint motion. The exact approach depends on the joint and may use screws, plates, or other fixation. The surgeon will explain which movements will change and how daily tasks can be adapted.

A specialist may discuss fusion when severe joint damage causes persistent pain, deformity, or instability and non-surgical care has not provided enough function. Examples include advanced ankle osteoarthritis, hallux rigidus, hand or thumb arthritis, and some patterns of rheumatoid arthritis. The decision considers work, mobility, hand demands, nearby joints, and the movement that would be sacrificed.

Before surgery, the team reviews medicines, health conditions, imaging, and the planned position. During the operation, the surgeon prepares the joint surfaces, places the bones together, and secures them with fixation such as a plate and screws. The wound is closed and the limb is protected. Instructions cover pain control, wound care, movement limits, and follow-up.

Early recovery focuses on swelling control, safe transfers, and protecting the fusion. As healing becomes clearer on follow-up assessment, activity and loading are progressed. Later rehabilitation works on strength, balance, footwear, or hand function. Bone healing and return to demanding activity vary, so the surgeon’s progression takes priority over a calendar.

Ask how your medicines, diabetes, smoking, circulation, and bone health affect healing. Seek urgent help for chest pain, sudden breathlessness, or a painful swollen calf. For the operated area, promptly report spreading redness, discharge, fever, numbness, or a change in colour or temperature.

Depending on the joint, options may include activity modification, footwear or splints, physiotherapy, medicines, injections, corrective surgery, or joint replacement. An ankle replacement is a different operation that aims to retain movement and is suitable only for selected patients. Compare expected pain relief, movement, rehabilitation, and future procedures with your specialist.

Look for an orthopedic surgeon experienced with the specific joint and ask who will coordinate imaging, wound checks, rehabilitation, and return to work or sport. Bring a list of medicines, previous treatments, and the activities you need to regain.
