Big Toe Arthritis: Joint Fusion Surgery Reduces Walking

Medically reviewed | Published: | Evidence level: 1A
A randomized controlled trial found that first metatarsophalangeal joint fusion reduced walking pain more effectively than watchful waiting in patients with painful hallux rigidus. The findings support surgery as an option for carefully selected patients, although recovery demands and potential complications remain important considerations.

Does Joint Fusion Reduce Pain From Big Toe Arthritis?

Quick answer: The randomized trial found that joint fusion reduced walking pain more than watchful waiting in people with painful hallux rigidus.

Hallux rigidus is arthritis of the first metatarsophalangeal joint, where the big toe meets the foot. Loss of cartilage can produce pain, swelling, stiffness and difficulty pushing off while walking. In the reported randomized trial, patients assigned to arthrodesis experienced greater improvement in walking pain than those managed with watchful waiting.

Randomization strengthens the comparison by reducing differences between treatment groups at the start of a trial. Surgery and watchful waiting cannot be fully blinded, however, and the results should be interpreted alongside information about patient selection, follow-up, complications and other outcomes. The findings do not mean that every person with big toe arthritis should undergo surgery.

How Does First MTP Joint Fusion Work?

Quick answer: The operation removes damaged joint surfaces and fixes the bones together so they heal as one stable, pain-resistant unit.

During first MTP joint arthrodesis, a surgeon prepares the arthritic bone surfaces and holds the toe in a functional position using fixation such as screws or a plate. Bone then grows across the former joint. Eliminating movement at the damaged joint can relieve arthritic pain, but the operation permanently removes motion from that joint.

Recovery commonly involves restrictions on activity and some form of protected weight-bearing while fusion develops, with the exact plan determined by the surgeon and fixation method. Recognized risks include infection, delayed healing or nonunion, hardware irritation, altered pressure under the foot and an unsatisfactory toe position. Smoking, impaired circulation and poorly controlled diabetes can interfere with bone healing and should be discussed before surgery.

Who Should Consider Surgery for Hallux Rigidus?

Quick answer: Fusion is generally considered when advanced arthritis causes persistent pain and nonoperative treatments no longer provide acceptable relief.

Initial management may include wider or stiffer-soled footwear, rocker-bottom shoes, activity modification, pain medication when medically appropriate and sometimes injections. These measures can reduce symptoms without eliminating the joint, making them reasonable options when pain is tolerable or surgery presents substantial risk.

A foot-and-ankle specialist can assess arthritis severity, deformity, bone quality, circulation and personal activity goals. Patients considering fusion should understand that the main objective is reliable pain reduction rather than restoration of normal movement. Shared decision-making should weigh expected improvement against rehabilitation time, surgical risk and the permanent loss of big toe joint motion.

Frequently Asked Questions

Many patients return to comfortable everyday walking after the bones have fused, although footwear choices and activities requiring substantial big toe bending may need adjustment. Recovery and final function vary by patient.

Fusion stops painful movement at the treated joint but does not restore its cartilage or motion. It is intended to provide a stable, less painful joint.

Watchful waiting avoids immediate surgical risk and may include footwear changes, activity modification and symptom-relieving treatment. Arthritis may remain stable or progress, so worsening pain or reduced function should prompt reassessment.
