Understanding Hallux Rigidus & Arthritis of the Big Toe

What Is Arthritis of the Big Toe?

Arthritis of the big toe most commonly refers to hallux rigidus, a degenerative joint condition that affects the first metatarsophalangeal joint, or 1st MTPJ, which is the joint connecting the big toe to the foot. As the name suggests, hallux rigidus causes progressive stiffness and loss of motion in the joint alongside pain and swelling. It is the most common form of arthritis in the foot.

The condition develops in stages. In the early stages, motion is somewhat limited, and pain occurs mainly during activity. As it progresses, bone spurs form around the joint, the cartilage deteriorates further, and range of motion decreases significantly. In advanced cases, the joint may become almost completely rigid, making normal walking mechanics difficult to maintain.

Causes & Risk Factors

Hallux rigidus is most often caused by wear and tear on the cartilage of the big toe joint over time. Contributing factors include:

• A family history of the condition or an inherited foot structure that places abnormal stress on the joint
• Previous injury to the big toe, such as a sprain or fracture that damaged the cartilage
• Flat feet or low arches, which alter how force is distributed through the forefoot
• Occupations or activities that require repeated bending of the big toe
• Inflammatory arthritis conditions, such as gout or rheumatoid arthritis

Symptoms

Symptoms of hallux rigidus typically develop gradually and worsen over time. Common signs include:

• Pain and stiffness in the big toe joint, especially during push-off when walking
• Swelling and inflammation around the joint
• A bony bump or bone spur on the top of the joint, which can cause additional pain when pressing against footwear
• Difficulty bending the toe upward, particularly when climbing stairs or squatting
• Limping or altered gait as the body compensates for joint pain
• Aching in the joint, even at rest, in more advanced cases

Diagnosis

Dr. Barnes diagnoses hallux rigidus through a physical examination of the joint, assessing range of motion, identifying the location of pain, and evaluating any visible bone spurs. Digital X-rays are a key part of the diagnostic process, as they show the degree of joint space narrowing, cartilage loss, and bone spur formation, all of which help determine the stage of the condition and guide treatment recommendations.

How Dr. Barnes Treats Arthritis of the Big Toe

Treatment for hallux rigidus is tailored to the severity of the condition. Dr. Barnes begins with conservative measures for earlier-stage cases and recommends surgical intervention when the joint has deteriorated to a point where non-surgical care is no longer effective.

Conservative Care Options

Conservative treatment focuses on reducing pain, managing inflammation, and slowing the progression of the condition:

• Footwear Modifications: Shoes with a stiff, rocker-bottom sole reduce the need to bend the big toe during walking, which can significantly decrease pain with each step. Avoiding flexible or thin-soled footwear is equally important.
• Orthotics: Orthotic devices prescribed by Dr. Barnes can limit motion at the big toe joint and offload pressure from the affected area, providing more consistent day-to-day relief than footwear changes alone.
• Anti-inflammatory Medications: Over-the-counter NSAIDs help manage pain and reduce swelling during flare-ups.
• Corticosteroid Injections: A precisely placed injection into the joint can provide meaningful short-term relief from pain and inflammation, particularly during periods of increased symptoms.
• Activity Modifications: Reducing activities that require significant push-off or toe bending can help manage symptoms without requiring surgical intervention.

Surgical Treatment: 1st MTPJ Arthrodesis

When conservative care is no longer controlling pain adequately, or when the joint has deteriorated to an advanced stage, surgical correction is typically the most reliable path to lasting relief. For hallux rigidus, the most definitive surgical option is a 1st MTPJ arthrodesis, a fusion of the first metatarsophalangeal joint.

During this procedure, Dr. Barnes removes the remaining articular cartilage from both sides of the joint, positions the big toe at the optimal functional angle, and fixates the first metatarsal head to the base of the proximal phalanx using a combination of a plate and screws. This type of rigid fixation stabilizes the joint completely, eliminates the source of arthritis pain, and allows for earlier weight-bearing compared to other fixation methods.

While fusion does eliminate motion at the joint, most patients find that the relief from pain far outweighs the loss of movement, particularly since the joint was already severely limited in motion before surgery. Many patients are surprised by how natural their gait feels after recovery.

The procedure typically takes approximately one hour. Patients are placed in a surgical boot following surgery and are able to bear weight with the boot during the recovery period. Sutures are generally removed at the two-week visit, and X-rays are taken at regular intervals to monitor bone healing. By weeks six to seven, Dr. Barnes assesses whether the patient can begin transitioning to a lace-up shoe. Most of the bone healing is complete by eight weeks, and patients gradually return to their regular activities from that point forward.
