When thumb pain becomes persistent, one question often comes up: which healthcare professional should you consult?
Between the general practitioner, physiotherapist, surgeon, or rheumatologist, the care pathway can seem unclear.

Yet the rheumatologist plays a key role in managing thumb osteoarthritis (rhizarthrosis). As a specialist in joint diseases, they are involved at several stages: diagnosis, pain assessment, and proposing non-surgical treatments… but their role is still often misunderstood.

So, when should you consult a rheumatologist for thumb osteoarthritis? And what can they actually offer you?

The rheumatologist: a joint specialist

The rheumatologist is the reference physician for joint diseases, including rhizarthrosis.

Their role is to provide deeper expertise when symptoms become more pronounced or when their progression requires a specialist’s opinion. They rely on a comprehensive assessment of the situation: pain intensity, functional impairment, and the stage of osteoarthritis progression.

In this context, they can refine initial treatments and take part in a step-by-step management approach, in line with the different treatment options available for thumb osteoarthritis.

Understanding the anatomy of the thumb

When should you consult a rheumatologist?

A rheumatologist is generally consulted at a later stage, when discomfort becomes more established.

Persistent pain

When pain becomes regular or even daily and affects simple movements, a specialist opinion helps to better understand the situation.

Progression of symptoms

Stiffness, reduced mobility, and loss of strength may indicate disease progression, as described in the different stages of rhizarthrosis.

Insufficient initial treatments

When the first solutions put in place are no longer enough to relieve symptoms, the rheumatologist can suggest adjustments or alternative approaches.

A key step before considering other treatments

The rheumatologist occupies a pivotal role in the care pathway.
They often intervene before more invasive solutions are considered, with a clear objective: relieve pain and delay the progression of symptoms as much as possible.

Their role is therefore to explore and optimize so-called “conservative” treatments, while evaluating their effectiveness over time.

What treatments does a rheumatologist offer?

Adapting medical treatments

They can adjust painkillers or anti-inflammatory medications depending on the intensity of the pain and the patient’s profile.

Supporting daily activities

They can also guide patients toward practical solutions to reduce stress on the joint, complementing advice already given on adapting daily movements.

Targeted treatments: injections

Injections are among the options frequently proposed at this stage of care.

They involve injecting a substance directly into the joint to reduce inflammation and relieve pain. Their use follows a stepwise approach, when simpler treatments are no longer sufficient.

Their effect can vary from person to person: some experience significant relief, while for others the improvement is more limited or temporary.

⚠️ Important information about injections

Repeated injections into the joint may have a negative impact on the progression of the disease.
When performed multiple times, they can weaken the structures around the joint and make potential surgical procedures more complex later on.

What next? When solutions are no longer enough

Over time, it may happen that the treatments offered no longer provide lasting relief.

In such situations, the rheumatologist also plays a guiding role.
They can help identify the right moment to consider other options, particularly when daily discomfort becomes too significant.

At this stage, the question of surgical solutions may be raised, in addition to the work already carried out beforehand.

A progressive and coordinated care pathway

The management of thumb osteoarthritis is based on a progressive approach.

The rheumatologist is part of a broader care pathway, alongside:

• the general practitioner, as the first point of contact
• rehabilitation professionals
• and, when appropriate, a hand surgeon

Each step allows care to be adjusted according to the progression of the disease, following a logic of continuous support over time.

Key takeaways

The rheumatologist is a key player in managing thumb osteoarthritis, often at a pivotal moment in the care pathway.

They help refine the diagnosis, adapt treatments, and propose solutions such as injections when pain becomes more significant. Their intervention follows a progressive approach aimed at preserving thumb function as much as possible.

When these approaches are no longer sufficient, they also help guide patients toward other options, in line with the evolution of the disease.

Understanding their role better means navigating your care pathway more effectively… and moving forward step by step with solutions tailored to each situation.
