Hallux rigidus

In brief

Hallux rigidus is a problem of the joint that connects the big toe to the foot, causing pain and loss of movement, especially when the toe bends upwards during walking. It is uncommon in children and adolescents and may be related to an injury of the cartilage and the bone beneath it. Identifying the cause makes it possible to choose the most suitable treatment and, whenever possible, preserve joint function.

Typical age

Mainly adults; uncommon in children and adolescents

Also known as

Stiff big toe · Hallux limitus

What is it?

Hallux rigidus affects the first metatarsophalangeal joint, located at the base of the big toe. This joint needs to move for normal walking, running and jumping. When there is pain, inflammation or damage to the joint surfaces, movement can become limited, especially when bending the toe upwards.

In adults it is usually related to progressive wear of the cartilage and the formation of bony prominences. In children and adolescents, however, it is uncommon, and other causes should be investigated, such as osteochondral lesions, injuries or changes in the joint surface. An osteochondral lesion affects the cartilage and the bone immediately beneath it, and can cause pain and loss of movement even in young patients.

Sometimes the problem starts after a sports injury or repeated minor trauma. Pain may appear when running, jumping or pushing off from the ground. If the lesion does not heal well, the restricted movement may persist and, in some cases, degenerative changes may develop in the joint.

So in an adolescent with pain and stiffness of the big toe, it is not enough to confirm that movement is limited: it is important to identify the cause and determine whether there is a cartilage or bone lesion that needs specific treatment.

Signs parents may notice

The most common symptoms are:

• Pain at the base of the big toe, especially when walking fast, running or jumping.
• Difficulty bending the toe upwards, for example when standing on tiptoe or pushing off while walking.
• Swelling around the joint after sport.
• A bump on top of the joint, which may be a bony prominence.
• Limping or a change in walking pattern to avoid loading or moving the painful toe.
• Lower sports performance, especially in activities that involve running, jumping and changes of direction.
• Pain with certain shoes, particularly if they press on the top of the joint.

These symptoms do not always mean hallux rigidus. In children and adolescents, persistent pain in this area should be investigated to rule out other injuries.

When to see a specialist

A medical assessment is advisable if:

• The pain at the base of the big toe keeps coming back or does not go away with rest.
• The adolescent has a progressive loss of movement.
• There is recurrent swelling or pain during sport.
• There is a limp or difficulty walking normally.
• The symptoms started after an injury or are preventing a return to sport.

When is it urgent?

An urgent assessment is recommended if there is sudden severe pain, marked swelling, obvious redness and warmth, fever, inability to put weight on the foot, or symptoms after a significant injury. These signs may indicate an acute injury or another problem that needs prompt attention.

How is it diagnosed?

The diagnosis starts with the clinical history and physical examination. The specialist will ask when the pain started, whether there was an injury, which activities trigger it and how it has changed over time.

The examination assesses the movement of the big toe, pain on movement, swelling and any bony prominences. The walking pattern is also observed, and the specialist checks whether the pain comes from the joint itself or from the surrounding structures.

Imaging is chosen according to the findings:

• X-rays: show the alignment of the bones, any bony prominences and possible joint changes.
• MRI: can be particularly useful in adolescents if an osteochondral lesion, a cartilage problem or a lesion not clearly visible on X-rays is suspected.
• CT scan: may be used in selected cases to study the bone structure in more detail.

In young patients, identifying a possible osteochondral lesion is especially important, as treatment can then aim to repair or protect the joint surface.

Treatment

Treatment depends on the cause, the extent of the lesion and how much function is limited. In adolescents the aim is to preserve the joint and prevent a treatable lesion from progressing to more advanced joint damage.

Conservative treatment

When the lesion and symptoms allow, treatment starts with non-surgical measures:

• Temporarily adjusting activity: reducing running, jumping and movements that cause pain.
• Suitable footwear: comfortable shoes that do not compress the joint and, in some cases, stiffer soles that reduce painful bending of the toe.
• Insoles or shoe modifications: can help reduce the load on the joint, depending on each patient.
• Local cold: can temporarily relieve pain and swelling after activity.
• Physiotherapy: can help restore movement and function when indicated, without forcing a painful joint.
• Pain relief: medicines should be used under the guidance of a health professional and taking the patient’s age into account.

If there is an osteochondral lesion, the specialist may also recommend limiting weight-bearing or activity for a certain period. Recovery time will depend on the location, size and stability of the lesion.

These measures can relieve symptoms, but not all cartilage lesions heal with conservative treatment alone. Follow-up is therefore important if the pain persists.

Surgical treatment

Surgery is considered when pain and functional limitation persist despite appropriate conservative treatment, or when there is an osteochondral lesion that, because of its characteristics, needs surgical repair.

The technique is chosen according to the cause and the condition of the joint. Options include:

• Arthroscopy or joint debridement: allows the joint to be examined through small incisions and certain lesions to be treated, loose fragments to be removed or inflamed tissue to be cleared when indicated.
• Treatment of the osteochondral lesion: depending on its size, depth and stability, this may include drilling or techniques that stimulate bone repair, fixation of selected fragments, or cartilage restoration procedures.
• Cheilectomy: removal of bony prominences that block movement. It is used in selected cases where there is bony impingement and the joint is otherwise in good condition.
• Reconstructive techniques: for specific osteochondral defects, procedures to repair or replace the damaged tissue may be considered. Their use in adolescents must be individualised, as the scientific evidence is limited.

In children and adolescents, the choice of technique must take into account growth, the extent of the lesion and the need to preserve the joint in the long term. Procedures used in adults with advanced arthritis are not necessarily suitable for young patients.

The operation may be performed under general or regional anaesthesia, or a combination, depending on the procedure and the patient. Some operations allow discharge on the same day; others require observation or a longer period without weight-bearing.

Outlook and recovery

Recovery depends on the type of lesion and the treatment carried out. There is no single timeline that applies to every adolescent with hallux rigidus.

• Conservative treatment: improvement may occur over several weeks, although osteochondral lesions may need longer periods of protection and follow-up.
• After arthroscopy or cheilectomy: weight-bearing and movement are usually regained gradually, depending on the procedure.
• After repair of an osteochondral lesion: weight-bearing may need to be limited for several weeks to protect the treated area and allow it to heal.
• School: a return is usually possible before a return to sport, as long as the pain is under control and getting around is safe.
• Return to sport: requires regaining movement, walking without pain and gradually tolerating load. If an osteochondral lesion has been repaired, the return may take several months.

The specialist will advise whether crutches, a post-operative shoe or immobilisation are needed, and when weight-bearing and activity can be increased. Clinical check-ups and, when appropriate, imaging are used to confirm progress before returning to sport.

Frequently asked questions

Is hallux rigidus common in adolescents?

No. It is much less common than in adults. When it appears in young patients, it is worth checking for an osteochondral lesion or another joint problem.

Can it get better without surgery?

In some cases, yes. Relative rest, suitable footwear and adjusting activity can relieve the symptoms. The outcome depends mainly on the cause and the characteristics of the lesion.

Can a cartilage injury cause stiffness of the big toe?

Yes. Osteochondral lesions of the head of the first metatarsal can cause pain and loss of movement and, in some cases, lead to degenerative changes.

When can my child return to sport?

It depends on the lesion and the treatment. The pain going away is not enough: function must be recovered and the joint must be able to tolerate activity without the symptoms getting worse.
